I am looking at 'the_post' hook which seems to fire inside the loop .

function rb_test_the_post($post){
if (($post->post_content) == '') {
continue;
}
}

<p>This gives me an error in Wordpress ( "The site is experiencing technical difficulties " and also in my editor as it doesnt see any while or if statement for the continue statement.) .

] | How can I run a wp cli command when a wordpress hook is called on my website.
On user registration hook, I would like to run a wp cli command to activate a license. | Depends on what you want to do. If you want to run the PHP code that's behind the WP-CLI code you might consider looking at <https://github.com/wp-cli/entity-command>
Maybe you don't actually need WP-CLI but the corresponding code behind it. Most WP-CLI commands have Wordpress equivalents. For example of what I was trying to do today, the `wp menu create "My Menu"` command is defined here:
<https://github.com/wp-cli/entity-command/blob/master/src/Menu_Command.php>. (It was much easier to find documentation for WP-CLI for this because 99% of results for Wordpress describe how to do it via the admin panel.)
Basically it just uses the WP function:
```
65: $menu_id = wp_create_nav_menu( $args[0] );
```
So `> wp menu create "My Menu"` on the commandline is roughly equivalent to `wp_create_nav_menu('My Menu')` in a `functions.php` file.
Similarly, the plugin command would be addressed as a WP-CLI extension command defined in [Plugin\_Command.php](https://github.com/wp-cli/extension-command/blob/master/src/Plugin_Command.php) which uses the Wordpress command [activate\_plugin()](https://developer.wordpress.org/reference/functions/activate_plugin/). If you want to know the WP version of the WP-CLI command you could look it up yourself or include the specific command you want to know in your question. |
360,490 | <p>I have a site that uses categories to output posts into categories.php. I don't have single posts using single.php </p>
<p>What I need is for a 'next 10' / 'previous 10' links in the category a site visitor is looking at. Here's my code from category.php</p>
<pre><code><?php if (is_category('black-metal')) : ?>
<h2><img src="<?php bloginfo('template_directory'); ?>/assets/img/black-metal-h2.png" alt="Black Metal" /></h2>
<?php $catquery = new WP_Query( 'cat=2&posts_per_page=10' ); ?>

``` | There can be a case that theme implements hooks via `do_action("action_name"`) but it's not forced to bind actual actions to it, as theme's developers might just did it to make theme more extensible, and in fact never use it inside theme.
So you can just bind your own code via `add_action("colormag_before", "your_function_name"`) in a child theme or plugin, and it will work.
And obviously if you want just to check if hook is used already somewhere in theme, just search through theme's code for `add_action("colormag_before"` (or `add_action( "colormag_before"` or `add_action('colormag_before'` or `add_action( 'colormag_before'`. these are just variation with different kinds of how it can be spelled)
If you can search via regular expression it will be `add_action\(\s*['"]colormag_before` |

I have found examples on the developer.wordpress site but I have been still struggling.
Localizing scripts:
[wp\_localize\_script()](https://developer.wordpress.org/reference/functions/wp_localize_script/#comment-content-1391)
In my theme's functions.php file, I have:
```
function wp_my_ajax_script() {
wp_localize_script( 'ajax_handle_agent_search', 'myAjax', admin_url( 'admin-ajax.php' ));
wp_enqueue_script( 'ajax_handle_agent_search' );
}
add_action( 'wp_enqueue_scripts', 'wp_my_ajax_script' );
```
And on my page, I've added a HTML code wdiget that contains:
```
<script>
jQuery(document).ready( function() {
console.log("Document loaded");
jQuery("#searchButton").click( function(e) {
console.log("Search button clicked");
console.log("Ajax: " . myAjax);
e.preventDefault();
var zipCode = document.getElementById("inputField").value;
console.log("Zip code entered: " + zipCode);
jQuery.ajax({
type : "post",
dataType : "json",
url : myAjax.ajaxurl,
data : {
action: "zip_search_action",
zip_code : zipCode
},
success: function(response) {
if(response.type == "success") {
console.log("In success");
document.getElementById("results").html = response.data;
}
else {
console.log("In success, in else!");
}
},
error: function(errorThrown){
console.log("In error, error thrown!");
console.log(errorThrown);
}
})
});
});
</script>
<input type="text" id="inputField">
<input type="button" value="Search" id="searchButton">
```
Then I load the page, enter a zip code in to the input field and click the button. The developer tools console shows:

Thank you | Here's just a few examples of what escaping looks like:
**Escaping URLS:**
```
<?php echo esc_url( home_url() ); ?>
```
**Escaping Content**
```
<?php echo esc_html( get_the_title() ); ?>
```
**Escaping Attributes**
```
<?php echo esc_attr( $my_class ); ?>
```
**Escaping Content but keep HTML**
```
<?php echo wp_kses_post( get_the_content() ); ?>
```
**Escaping Emails**
```
<?php echo sanitize_email( $email_address ) ); ?>
```

Specifically, it's used to adding body classes, removing body classes, conditionally adding body classes and some use cases.
>
> **The Body Class: What Can It Be Used For?**
>
>
>
The body class in WordPress is a class or series of classes that are applied to the HTML body element. This is useful for applying unique styles to different areas of a WordPress site as body classes can be added conditionally.
* This is a really simple way to add body classes and is especially useful if you are creating a theme, using this below code is header.php body element
>
> < body `<?php body_class();` ?> >
>
>
>
**Adding Multiple Body Classes**
There may be times when you want to add more than one body class. This can be achieved using a simple
>
> `< body <?php body_class( array( "class-one", "class-two", "class-three" ) ); ?>>`
>
>
>
**Conditionally Adding a Body Class**
This example uses the WooCommerce conditional method of is\_shop() :
```
<?php if ( is_shop() ) { body_class( 'is-woocommerce-shop' ); } else { body_class(); } ?>
```
**Adding a Body Class by Filter**
It's possible to use a WordPress filter to add a body class, This code can either go in your themes functions.php or within your plugin.
```
add_filter( 'body_class','my_body_classes' );
function my_body_classes( $classes ) {
$classes[] = 'your-custom-class-name';
return $classes;
}
```

In this post I assume that you already have basic knowledge how to work with WP\_Query class in WordPress. Before I begin, I want to show you some very simple examples. The similar examples you can find in WordPress Codex.
As you know all the posts have the metadata you can populate in "Custom fields" metabox (the metabox by the way can be hidden). So, for example, if you want to get a post with meta key show\_on\_homepage and meta value on, you can do it the following way:
```
$rd_args = array(
'meta_key' => 'show_on_homepage',
'meta_value' => 'on'
);
$rd_query = new WP_Query( $rd_args );
```

The simple example below allows you to get all the posts with a specific custom field value. Let’s just get all the posts with custom field name "color" and custom field value white.
```
// the meta_key 'color' with the meta_value 'white'
$rd_args = array(
'meta_query' => array(
array(
'key' => 'color',
'value' => 'white'
)
)
);
$rd_query = new WP_Query( $rd_args );
```
If you look at the post edit page (in admin area) in any post which matches the query, you will see the following in the "Custom Fields" section:

Why should I use it ?</strong>\":</p>\n\n<blockquote>\n <p>That <code>key</code> parameter is the <strong>meta key</strong> (or the custom field's <em>name</em>\n — think of it like post slugs). And without it, WordPress/MySQL\n won't know what meta should be queried for since <code>WP_Query</code> doesn't\n query all (post) meta by default.</p>\n \n <p>You can find all the <code>WP_Query</code> parameters\n <a href=\"https://developer.wordpress.org/reference/classes/wp_query/parse_query/\" rel=\"nofollow noreferrer\">here</a>\n and\n <a href=\"https://developer.wordpress.org/reference/classes/wp_meta_query/__construct/\" rel=\"nofollow noreferrer\">here</a>\n for the <code>meta_query</code> (meta query clauses).</p>\n</blockquote>\n\n<h3>Additional Notes</h3>\n\n<p>These are additional details, which may be useful to you, in addition to the other answer.</p>\n\n<ol>\n<li><p>The <code>meta_query</code> parameter, or WordPress meta queries, are not only used with <code>WP_Query</code> or for searching/filtering posts, but also for searching/filtering terms like the default/built-in Category (<code>category</code>) taxonomy, comments, users, and sites in a Multisite network.</p>\n\n<p>However, the default Custom Fields editor/metabox is only available for posts. For terms, users, etc., you can code your own <em>metabox</em> or use a plugin like Advanced Custom Fields.</p></li>\n<li><p>In reply to the \"<strong>Can I use anything as key ?</strong>\":</p>\n\n<p><em>Yes, basically.</em></p>\n\n<p>But technically, a meta key is limited to <em>a maximum of 255 characters</em> and plugins/themes (and you) can use <a href=\"https://developer.wordpress.org/?s=sanitize_%7B%24object_type%7D_meta_%7B%24meta_key%7D\" rel=\"nofollow noreferrer\">filter hooks</a> to allow/disallow certain characters, limit the key length, etc.</p>\n\n<p>And despite what I said in the original answer (\"think of it like post <em>slugs</em>\"), meta key can actually be like a post <em>title</em> which contains spaces as in <code>Continue Reading</code> or <code>Favorite Music in the 90's</code>.</p></li>\n</ol>\n"

``` | Basically meta\_query parameter of WP\_Query allows you to search WordPress posts / pages / custom post types by their meta data and sort the result.
In this post I assume that you already have basic knowledge how to work with WP\_Query class in WordPress. Before I begin, I want to show you some very simple examples. The similar examples you can find in WordPress Codex.
As you know all the posts have the metadata you can populate in "Custom fields" metabox (the metabox by the way can be hidden). So, for example, if you want to get a post with meta key show\_on\_homepage and meta value on, you can do it the following way:
```
$rd_args = array(
'meta_key' => 'show_on_homepage',
'meta_value' => 'on'
);
$rd_query = new WP_Query( $rd_args );
```
>
> * Query Posts by a Meta Value
>
>
>
The simple example below allows you to get all the posts with a specific custom field value. Let’s just get all the posts with custom field name "color" and custom field value white.
```
// the meta_key 'color' with the meta_value 'white'
$rd_args = array(
'meta_query' => array(
array(
'key' => 'color',
'value' => 'white'
)
)
);
$rd_query = new WP_Query( $rd_args );
```
If you look at the post edit page (in admin area) in any post which matches the query, you will see the following in the "Custom Fields" section:

360,721 | <p>I'm writing a simple plugin that shows on pages/posts a form with customized style for input fields, checkboxes, buttons, etc... via a shortcode. When user writes the shortcode in the page, it generates some CSS, some HTML and some JavaScript but result is not rendered as I want I think because of active theme CSS.
In fact if I wrote the same combination of CSS, HTML and JavaScript in a simple HTML file rendering is perfect and if, in WordPress, I change theme, rendering changes...</p>
<p>How can I prevent the active theme from interfering with my plugin by rendering the controls as if they were inserted in a simple HTML page?</p>

``` | You can make sure that your CSS is [enqueued](https://developer.wordpress.org/reference/functions/wp_enqueue_style/) after your theme's CSS and also make sure that your CSS is using rules that are more specific. This will help in making your CSS override the theme's CSS.
Worse-case scenario you could add !important to a few CSS rules if you are having a hard time overriding your theme.
When you use `wp_enqueue_style` you should use the `wp_enqueue_scripts` hook, it offers a priority parameter. Here is an example.
```
function wpse_my_plugin_styles() {
$plugin_url = plugin_dir_url( __FILE__ );
wp_enqueue_style( 'my_styles', $plugin_url . "/css/style.css");
}
add_action('wp_enqueue_scripts', 'wpse_my_plugin_styles', 999);
```
You could also create a [child theme](https://developer.wordpress.org/themes/advanced-topics/child-themes/). This would allow you to customize the CSS however you want and not worry about it getting wiped out if the plugin updates. |
360,745 | <p>I asked a <a href="https://wordpress.stackexchange.com/questions/360418/enhancing-gutenberg-featured-image-control">previous question</a>, and got a helpful answer that got me going quite a ways. The present problem is unrelated, but IMO reflects the dearth of documentation suitable for those of us who aren't familiar with some of the nuances of javascript, are completely new to Gutenberg development, and yet need to tweak the new Wordpress here and there. I'll state right up front that I'm new to javascript, and suspect that my issue is related to that fact.</p>
<p>As stated in my previous question, I'm working on modifying the featured image control in the admin edit screen of a custom post type. I want to add a checkbox, and a text input field to capture a user-supplied resource URL.

] | I asked a [previous question](https://wordpress.stackexchange.com/questions/360418/enhancing-gutenberg-featured-image-control), and got a helpful answer that got me going quite a ways. The present problem is unrelated, but IMO reflects the dearth of documentation suitable for those of us who aren't familiar with some of the nuances of javascript, are completely new to Gutenberg development, and yet need to tweak the new Wordpress here and there. I'll state right up front that I'm new to javascript, and suspect that my issue is related to that fact.
As stated in my previous question, I'm working on modifying the featured image control in the admin edit screen of a custom post type. I want to add a checkbox, and a text input field to capture a user-supplied resource URL. I have a javascript file that loads on the page in question, along with all the requisite dependencies to work with Gutenberg, JSX, and all of the react-based components (react-devel, react-dom, babel, wp-blocks, wp-i18n, wp-element, wp-editor, wp-hooks). I've also got a filter in place that sets the script type of my .js file to 'text/babel' so JSX interprets correctly. I don't think I've missed anything.
Here's a version of my .js file that displays a heading and rich text field. It's not what I'm after but it does work and there aren't any complaints in the javascript console. At this point I'm still trying to figure out the building blocks I need, and how to use them.
```
window.addEventListener("load", function(event){
console.log("featured_image.js loaded and functional...");
});
const el = wp.element.createElement;
// const withState = wp.compose.withState;
const setState = wp.data.setState;
const withSelect = wp.data.withSelect;
const withDispatch = wp.data.withDispatch;
const { CheckboxControl } = wp.editor;
const { RichText } = wp.editor;
const { useState } = wp.element;
const { TextControl } = wp.components
const { withState } = wp.compose;
wp.hooks.addFilter(
'editor.PostFeaturedImage',
'dsplugin/featured-image-as-video',
wrapPostFeaturedImage
);
//this works
const MyRichTextField =
<RichText
placeholder="placeholder text"
/>
;
function wrapPostFeaturedImage( OriginalComponent ) {
return function( props ) {
return (
el(
wp.element.Fragment,
{},
// 'Prepend above',
el(
OriginalComponent,
props
),
<strong>this is a test</strong>,
// MyCheckboxControl
MyRichTextField
)
);
}
}
```
Here's what the output looks like...
[](https://i.stack.imgur.com/wjur5.png)
When I try to add a checkboxControl though, using the same methodology I used for the RichText field, I run into problems. This code...
```
const MyCheckboxControl =
const [ isChecked, setChecked ] = useState( true );
<CheckboxControl
heading="User"
label="Is author"
help="Is the user a author or not?"
checked={ isChecked }
onChange={ setChecked }
/>
;
```
Doesn't work. And the javascript console says...
```
SyntaxError: ... Unexpected token (28:4)
27 | const MyCheckboxControl = () => (
> 28 | const [ isChecked, setChecked ] = useState( true );
| ^
29 | <CheckboxControl
30 | heading="User"
31 | label="Is author"
```
However, this is exactly how the [Gutenberg documentation](https://developer.wordpress.org/block-editor/components/checkbox-control/) says we should implement a CheckboxControl. At least when creating blocks. Are things different in the sidebar? I tried a TextControl, as follows...
```
const MyTextControl = withState( {
className: '',
} )( ( { className, setState } ) => (
<TextControl
label="Additional CSS Class"
value={ className }
onChange={ ( className ) => setState( { className } ) }
/>
) );
```

I feel like I have a fundamental disconnect with what's going on here. What am I missing? | You can make sure that your CSS is [enqueued](https://developer.wordpress.org/reference/functions/wp_enqueue_style/) after your theme's CSS and also make sure that your CSS is using rules that are more specific. This will help in making your CSS override the theme's CSS.
Worse-case scenario you could add !important to a few CSS rules if you are having a hard time overriding your theme.
When you use `wp_enqueue_style` you should use the `wp_enqueue_scripts` hook, it offers a priority parameter. Here is an example.
```
function wpse_my_plugin_styles() {
$plugin_url = plugin_dir_url( __FILE__ );
wp_enqueue_style( 'my_styles', $plugin_url . "/css/style.css");
}
add_action('wp_enqueue_scripts', 'wpse_my_plugin_styles', 999);
```

] | I have a custom pos type created in functions.php and working great - except I need to have categories enabled. I have looked through other answers here, and am still not able to figure it out. In my code i have `taxonomies => array('categories', 'tags')` but it is not working.

360,845 | <p>I've developed a custom theme with a custom post type named <code>events</code>. For some reason, however, WP refuses to use my archive page template with the file name <code>archive-events.php</code> per WP's template hierarchy. WP keeps defaulting to <code>index.php</code> as the template for this post type.</p>
<p>Previously I had a page configured in WP that was set to the slug <code>/events/</code> which is now the slug of the custom post type. That page is now deleted, and I don't know if this is the issue that is causing WP to refuse to use <code>archive-events.php</code> for my archive listing for the custom post type. I've tried modifying and re-saving my permalink structure, and that hasn't worked. Currently the permastruct is set to "Post name," i.e. <code>http://my.domain/post-name/</code></p>
<p>More details:</p>
<ul>
<li>I've registered a custom post type of <code>events</code> (code below)</li>
<li>The slug of the post type is "events" and individual posts are rendering successfully at <code>http://domain.com/events/post-name</code></li>
<li>The archive page for the post type is accessible at <code>/events/</code> but is using <code>index.php</code> even though I've created an archive template for the post type as <code>archive-events.php</code></li>
<li>To confirm what template WP is using to render the archive page for the custom post type, I've created a function that outputs the <code>$GLOBALS['current_theme_template']</code> being used to render the page. This confirms that WP is using <code>index.php</code> to render the archive page.</li>
<li>In my <code>header.php</code> file I'm echoing the function <code>get_post_type_archive_link('events')</code> to confirm that WP thinks that the archive page for my custom post type should be <code>http://domain.com/events/</code></li>
<li>The <code>archive.php</code> and <code>index.php</code> WP templates are served as expected, but the template for the custom post type is skipped by WP no matter what</li>
<li>As a test, I renamed my existing custom post type to something new, remapped all of my queries to that CPT, and updated my template names accordingly. Still, WP refuses to serve <code>cpt-archive.php</code> as the template for the custom post type and serves either <code>archive.php</code> or <code>index.php</code> instead.</li>
</ul>

361,204 | <p>I am working on a project that needs a website with region specific pages. One of the key requirements is that while the blog, about and other pages are the same for all regions pricing, staff, booking and events pages would be specific to the region. </p>
<p>Think something like this: <a href="https://locations.massageenvy.com/utah/american-fork/356-north-750-west.html" rel="nofollow noreferrer">https://locations.massageenvy.com/utah/american-fork/356-north-750-west.html</a></p>
<p>One caveat in this case is that we don't necessarily have a specific store location, but rather a service area (kind of like handyman service websites).</p>
<p>Is MultiSite with subdirectories the correct solution in this case? Is there a different (better) way to build a site like this?</p>
<p>If multisite is the correct solution, is there an existing plugin for building a location search feature?</p>

] | I am working on a project that needs a website with region specific pages. One of the key requirements is that while the blog, about and other pages are the same for all regions pricing, staff, booking and events pages would be specific to the region.
Think something like this: <https://locations.massageenvy.com/utah/american-fork/356-north-750-west.html>
One caveat in this case is that we don't necessarily have a specific store location, but rather a service area (kind of like handyman service websites).
Is MultiSite with subdirectories the correct solution in this case? Is there a different (better) way to build a site like this?
If multisite is the correct solution, is there an existing plugin for building a location search feature? | The second argument of `wp_unique_post_slug` filter is post id. You can utilize that to generate the slug only once while creating the post for the first time.
**Method 1:**
```
add_filter( 'wp_unique_post_slug', 'unique_slug_108286', 10, 2 );
function unique_slug_108286( $slug, $postId ) {
if ( ! $postId ) {
$n = 4;
$slug = bin2hex( random_bytes( $n ) ); //just an example
}
return $slug;
}
```
*Other method would be using post meta to indicate whether a slug has been generated.*
**Method 2:**
```
add_filter( 'wp_unique_post_slug', 'unique_slug_108286', 10, 2 );
function unique_slug_108286( $slug, $postId ) {
if ( $postId && ! get_post_meta( $postId, 'slug_generated', true ) ) {
$n = 4;
$slug = bin2hex( random_bytes( $n ) ); //just an example
update_post_meta( $postId, 'slug_generated', true );
}
return $slug;
}

361,205 | <p>I have a website that sells gaming related stuff, i need to show some buffs as icons/small images under every product below the product image, on the archive/category page, apparently there is no such option nor plugin on the internet that can help me (i would like to be corrected on this please)</p>
<p>So i am trying to work around this on my own, i have very basic coding knowledge.</p>
<p>They way i am trying to do it is by: </p>
<ol>
<li>These icons are common to the products but their combinations are unique per
product, to make it easy i made them as attributes so i can easily assign
them per product.</li>
<li>Installed the variation swatches for woocommerce plugin so
attributes can have there own images </li>
<li>Made an attribute and made its sub-attributes as my icons and attached
images.</li>
<li>All my products are simple downloadable products so variation
swatches for woocommerce is of no help as it only works for variable
products, but it gave attributes their own images.</li>
<li>Currently i can output the values on attributes on my product cat/archive page with the following
code but not images as i have no idea how to call them.</li>

<p>I need advice if this is a good approach or is there already a solution for this ? If not then how can i go about calling the images attached to the attributes! </p>

] | I have a website that sells gaming related stuff, i need to show some buffs as icons/small images under every product below the product image, on the archive/category page, apparently there is no such option nor plugin on the internet that can help me (i would like to be corrected on this please)
So i am trying to work around this on my own, i have very basic coding knowledge.
They way i am trying to do it is by:
1. These icons are common to the products but their combinations are unique per
product, to make it easy i made them as attributes so i can easily assign
them per product.
2. Installed the variation swatches for woocommerce plugin so
attributes can have there own images
3. Made an attribute and made its sub-attributes as my icons and attached
images.
4. All my products are simple downloadable products so variation
swatches for woocommerce is of no help as it only works for variable
products, but it gave attributes their own images.
5. Currently i can output the values on attributes on my product cat/archive page with the following
code but not images as i have no idea how to call them.
I can display the attributes and there values using the following code
```
<?php
add_action( 'woocommerce_after_shop_loop_item', 'loop_attributes', 20 );
function loop_attributes() {
global $product;
if( ! is_object( $product ) ) {
$product = wc_get_product( get_the_id() );
}
$win_val = $product->get_attribute('pa_wins');
$hour_val = $product->get_attribute('pa_hours');
$badge_val = $product->get_attribute('pa_badges');
$token_val = $product->get_attribute('pa_token');
echo '<img src="' . $token_val . '" class="aligncenter" style="margin-bottom: 20px;" />';
echo '<span class="attrs1"><i style="color:#1c7e5a;" class="fas fa-trophy"></i> Wins:</span>'.'<span
class="attrs2"> '.$win_val.' </span>';
echo '<span class="attrs1"><i style="color:#1c7e5a;" class="fas fa-hourglass"></i> Hours:

echo '<span class="attrs1"><i style="color:#1c7e5a;" class="fas fa-ribbon"></i> Badges:
</span>'.'<span class="attrs2"> '.$badge_val.' </span>';
}
add_filter( 'woocommerce_hide_invisible_variations', '__return_false' );
?>
```
The code above shows the corresponding attribute name and their values on the product cat/archive page,
The attribute pa\_token has images attached to their values,
I want the pa\_token to output its attached images instead of values, in the below example the code for pa\_token is a representation of what i want its not a working code,
```
echo '<img src="' . $token_val . '" class="aligncenter" style="margin-bottom: 20px;" />';
```
I need advice if this is a good approach or is there already a solution for this ? If not then how can i go about calling the images attached to the attributes!
**Update 1:**
When i put this code
```
function loop_attributes() {
global $product;
if( ! is_object( $product ) ) {
$product = wc_get_product( get_the_id() );
}
echo '<pre>', print_r($product->get_attributes(), 1), '</pre>';
$token_val = $product->get_attribute('pa_token');
echo '<pre>', print_r($token_val, 1), '</pre>';
}
add_action( 'woocommerce_after_shop_loop_item', 'loop_attributes', 10, 0 );
```
I get the following output
```
Array
(
[pa_token] => WC_Product_Attribute Object
(
[data:protected] => Array
(
[id] => 9
[name] => pa_token
[options] => Array
(
[0] => 210
[1] => 211
)
[position] => 6
[visible] => 1
[variation] =>
)
)
)
a, bb
```
a, bb are the sub attributes/values that have images attached to them
pa\_token-> a - Icon 1, bb - Icon 2
**Update 2:**
So if i do the following code
```
var_dump( get_term_meta( 210 ) );
```
I get the following output, looks like we are heading to the right path
```
array(6) { ["order_pa_token"]=> array(1) { [0]=> string(1) "0" }
["product_attribute_image"]=> array(1) { [0]=> string(5) "12706" }
["image_size"]=> array(1) { [0]=> string(9) "thumbnail" } ["show_tooltip"]=>
array(1) { [0]=> string(4) "text" } ["tooltip_text"]=> array(1) { [0]=>
string(3) "aaa" } ["tooltip_image"]=> array(1) { [0]=> string(1) "0" } }
```
I guess we have the meta now, now what should be the relevant code to only output the images with there tooltips on the category/archive page ?
**Update 3:**
By updating the code to :
```
function loop_attributes() {
global $product;
if( ! is_object( $product ) ) {
$product = wc_get_product( get_the_id() );
}
// Get Product Variations - WC_Product_Attribute Object
$product_attributes = $product->get_attributes();
// Not empty, contains values
if ( !empty( $product_attributes ) ) {
foreach ( $product_attributes as $product_attribute ) {
// Get options
$attribute_options = $product_attribute->get_options();
// Not empty, contains values
if ( !empty( $attribute_options ) ) {
foreach ($attribute_options as $key => $attribute_option ) {
// WP_Term Object
$term = get_term($attribute_option); // <-- your term ID
echo '<pre>', print_r($term, 1), '</pre>';
}
}
}
}
}
add_action( 'woocommerce_after_shop_loop_item', 'loop_attributes', 10, 0 );
```
i get the below output
```
<pre>

```
**Update 4:**
So i was not able to solve my problem earlier, then i switched the plugin to Category and Taxonomy Image by Aftab Hussain and used the following code to call images on the category/archive loop page:
```

if( ! is_object( $product ) ) {
$product = wc_get_product( get_the_id() );
}
$token_imgs = get_the_terms( get_the_ID(), 'pa_token');
foreach ( (array) $token_imgs as $token_img ) {
$terms = $token_img->term_id;
$meta_image = get_wp_term_image($terms);
echo '<ul><li><img src="' . $meta_image . '" class="tokenimg" " /></li>

}
}

pa\_token is my attribute with sub attributes that have images

(array) inside foreach loop is used to not return anything if the value is null, otherwise all the other products with no attributes get an ugly php debug error on the main page, let me know if there is a non hack way to handle this.

Thanks for your help guys, for giving me the right direction.
**Notes from Sally:**
1. I'd just remove the `$product` since you don't really need it there because you used `get_the_terms()` and not a WooCommerce-specific function for getting the `pa_token` terms.
2. I don't recommend the `(array) $token_imgs`. Instead, make sure the `$token_imgs` is not a `WP_Error` instance and that it's not an empty array.
3. Instead of multiple `ul` (`<ul><li></li></ul> <ul><li></li></ul> <ul><li></li></ul>...`), I'd use multiple `li` (`<ul><li></li> <li></li> <li></li>...</ul>`). :)
So my code would be:
```php
add_action( 'woocommerce_after_shop_loop_item', 'attribute_img_loop', 20 );
function attribute_img_loop() {
$token_imgs = get_the_terms( get_the_ID(), 'pa_token' );

```
$price1 = $wpdb->get_row( "SELECT * FROM $wpdb->prices WHERE id = 9" );
```
How do this? | So I was not able to solve my problem earlier, then I switched the plugin to "[Category and Taxonomy Image](https://wordpress.org/plugins/wp-custom-taxonomy-image/)" (by Aftab Hussain) and used the following code to display the icons on category/archive pages:
```php
add_action( 'woocommerce_after_shop_loop_item', 'attribute_img_loop', 20 );
function attribute_img_loop() {
global $product;
// Check that we got the instance of the WC_Product object, to be sure (can
// be removed)
if ( ! is_object( $product ) ) {
$product = wc_get_product( get_the_ID() );
}
$token_imgs = get_the_terms( get_the_ID(), 'pa_token' );
foreach ( (array) $token_imgs as $token_img ) {
$terms = $token_img->term_id;
$meta_image = get_wp_term_image( $terms );
echo '<ul><li><img src="' . $meta_image . '" class="tokenimg" /></li></ul>';
}
}
```
* `pa_token` is my attribute with sub-attributes/terms that have images.
* `foreach` loop is used to output all the sub-attributes used per product, otherwise it will output only the first result.
* `(array)` inside the `foreach` loop is used to not return anything if the value is null, otherwise all the other products with no attributes get an ugly PHP debug error on the main page.
Thanks for your help guys, for giving me the right direction.
**Notes from Sally:**
1. I'd just remove the `$product` since you don't really need it there because you used `get_the_terms()` and not a WooCommerce-specific function for getting the `pa_token` terms.
2. I don't recommend the `(array) $token_imgs`. Instead, make sure the `$token_imgs` is not a `WP_Error` instance and that it's not an empty array.
3. Instead of multiple `ul` (`<ul><li></li></ul> <ul><li></li></ul> <ul><li></li></ul>...`), I'd use multiple `li` (`<ul><li></li> <li></li> <li></li>...</ul>`). :)
So my code would be:
```php
add_action( 'woocommerce_after_shop_loop_item', 'attribute_img_loop', 20 );
function attribute_img_loop() {
$token_imgs = get_the_terms( get_the_ID(), 'pa_token' );
if ( ! is_wp_error( $token_imgs ) && ! empty( $token_imgs ) ) {
echo '<ul>';
foreach ( $token_imgs as $term ) {
$meta_image = get_wp_term_image( $term->term_id );
echo '<li><img src="' . $meta_image . '" class="tokenimg" /></li>';
}
echo '</ul>';

] | I'd like to have the checkout billing form on two columns. Is there a way to wrap half of the fields in a div and the other hald in another so that it's easy to use a `float` or `flexbox`?
The form is invoked in `form-billing.php` via `woocommerce_form_field` in a `forEach` loop, but I'm clueless as to where I could find the form template itself to modify it.
I'm also aware that a `woocommerce_checkout_fields` filter exists, but that doesn't seem helpful to wrap fields in some divs. | My question was wrong because I had forgotten some things I had tried earlier. Splitting the form field within two divs is easy task:
```
// form-billing.php
<div class="woocommerce-billing-fields__field-wrapper">
<?php
$fields = $checkout->get_checkout_fields('billing');
$fields_half_count = round(count($fields) / 2);
$i = 0;
echo '<div class="one">';
foreach ($fields as $key => $field) {
if ($i++ == $fields_half_count) echo '</div><div class="two">';
woocommerce_form_field($key, $field, $checkout->get_value($key));
}
echo '</div>';
?>
</div>
```
Now the issue is that the when the checkout JS kicks in, it rearranges all fields and places them in one div.
One could disable it, but it's used to get shipping rates based on shipping country, manages the fields based on country too (US has states, Spain has provinces etc…), so disabling it isn't really an option.
The only workaround I've found so far is to use the CSS `column-count: 2` on `.woocommerce-billing-fields__field-wrapper` to have the browser display it on two columns.
The layout isn't perfect, but it's the best option I've found so far. Otherwise, one needs to use a custom JS to handle the work done by the WooCommerce checkout JS. |

Your setting for `WP_DEBUG_DISPLAY` is telling it to display errors (set to `true`), and then you're turning around and telling it not to (`ini_set` to 0).

1. A remote file (which I changed to `wp_remote_post()`)
2. A local file in the plugin dir (what this question is about)

So, I did. But...
Solving usage *1. A remote file* (above) got me to reading and thinking about a better tool for usage *2. A local file* (above)
===============================================================================================================================
In the [WordPress HTTP API](https://developer.wordpress.org/plugins/http-api/) docs, there is no alternative for `file_get_contents()` on local files, nothing like `wp_file_get_contents()`.
*(I understand this may seem strange since local files of a plugin are often static, but I am writing extra files to save cost, and I politely don't want to open that discussion. Besides, [this approved plugin from someone else](https://wordpress.org/plugins/string-locator/), [code here](https://plugins.trac.wordpress.org/browser/string-locator/trunk/string-locator.php), uses `file_get_contents()`, thus proving my own need is legitimate, but it doesn't prove that `file_get_contents()` is 'proper' WordPress-practice.)*
From [this blog post](https://www.tutdepot.com/alternative-functions-file_get_contents/), clearly this was a big discussion for `file_get_contents()` for *remote files*. But, I don't see much on the web about a WordPress function for *local files*. From the post:

...I want to take that discussion to *local files* and build this plugin right.
My code (current and attempted)
===============================
I simply need to confirm whether a local file in the plugin directory exists, then confirm whether it contains a certain string. I thought it best to use `file_get_contents()` for local files in PHP from [this question on SE](https://stackoverflow.com/questions/9059026/php-check-if-file-contains-a-string). But, this is WordPress. Currently, I am using:
```
if ( ( ! $wp_filesystem->exists ( $check_this_file ) )
|| (strpos ( file_get_contents ( $check_this_file ),
$check_this_string ) === false ) )
```
I tried using [WP\_Filesystem\_Direct::get\_contents](https://developer.wordpress.org/reference/classes/wp_filesystem_direct/get_contents/) instead:
```
if ( ( ! $wp_filesystem->exists ( $check_this_file ) )
|| (strpos ( WP_Filesystem_Direct::get_contents ( $check_this_file ),
$check_this_string ) === false ) )
```
...but I got this error:
>
> `Deprecated: Non-static method WP_Filesystem_Direct::get_contents() should not be called statically`
>
>
>
What should I do?
=================
I'm not sure because there isn't even a #get-contents tag on WP.SE at the time of asking, but the function exists both in the framework and in the docs.
I want to know the "WordPress way" for plugins to read a plugin file's contents for a string test:
* `file_get_contents()` (what I have now)
* `WP_Filesystem_Direct::get_contents()` (but how do I make it work without the error?)
* or some ***proper-reliable*** usage of `wp_filesystem()` or similar | The alternate of using `file_get_contents()` is to initiate `WP_Filesystem` and use its `$wp_filesystem->get_contents` method.
Here is a clean example method on how to use it
**Example**
```
<?php
/**
* This method gets a list of the most popular Google web fonts.
* Initialize the WP filesystem and no more using file_put_contents function
*
* @see wp_filesystem()
* @see get_parent_theme_file_path()
* @return array A list of Google web fonts
*/
function mm_get_google_fonts() {
// Call globals
global $wp_filesystem;
// You have to require following file in the front-end only. In the back-end; its already included
require_once ( ABSPATH . '/wp-admin/includes/file.php' );
// Initiate
WP_Filesystem();

1. you need to use [wp\_get\_object\_terms](https://developer.wordpress.org/reference/functions/wp_get_object_terms/) to get a list of terms info first with count for handling.
2. compare each tag count, if the count > 1 then create the link and output

362,882 | <p>I'm trying to accomplish this simple task through different plugins, but I can't find the right one for different reasons.</p>
<p>I have a Login Page with a login form. When user logs in, he's redirected to a specific page (based on user role). If the user visits again the Login Page, the login form displays a Welcome message with dashboard, profile and logout links (see pics).</p>
<p><a href="https://i.stack.imgur.com/Hdznf.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/Hdznf.png" alt="enter image description here"></a></p>
<p>Since I need to avoid that and need logged in user to only visit the specific page based on their role, I'd like to redirect away logged in users from Login Page to Specific Page.</p>
<p>eg: Paul is a user with "apple" role. He logs in and gets redirected to Apple Page. Then he browses the website and try to visit the Login Page. As he tries, he's redirected to Apple Page. The same applies to Ron, whose role is "banana", so when he tries to visit Login Page he's redirected to Banana Page.</p>
<p>My biggest issue is that every plugin helps with redirection AFTER login, and that is easly manageable. Do you know any easy way to accomplish that or any suggestion on where to look? </p>

eg: Paul is a user with "apple" role. He logs in and gets redirected to Apple Page. Then he browses the website and try to visit the Login Page. As he tries, he's redirected to Apple Page. The same applies to Ron, whose role is "banana", so when he tries to visit Login Page he's redirected to Banana Page.
My biggest issue is that every plugin helps with redirection AFTER login, and that is easly manageable. Do you know any easy way to accomplish that or any suggestion on where to look? | Because [get\_the\_term\_list()](https://developer.wordpress.org/reference/functions/get_the_term_list/) create the html link for you.
So
1. you need to use [wp\_get\_object\_terms](https://developer.wordpress.org/reference/functions/wp_get_object_terms/) to get a list of terms info first with count for handling.
2. compare each tag count, if the count > 1 then create the link and output
I have just tried. It works
```
<p class="meta-tag-list">
<?php
$terms = wp_get_object_terms($post->ID, 'category'); // replace 'category' (default Post post type taxonomy name) with your taxonomy such as 'topic'
foreach ($terms as $key => $term) {
if( $term->count > 1 ) { // if the count is > 1, output, if not, then nothing will happen
$link = get_term_link( $term->term_id );
echo '<a href="' . esc_url( $link ) . '" rel="tag">' . $term->name . '</a>';
}
}
?>
</p>

362,888 | <p>This must be a very amateurish question but... </p>
<p>I'm using page templates from the dropdown menu in page editor but I can't find their source code. I know that usually this can be found in themes/"theme name"/page-templates, but no matter how hard I look, I just can't find the files for several of the templates I'm using ("Full-Width Template", "Page with Navigation Only" etc.). Any tips?</p>
<p>Thanks a lot!</p>

With code above its working completely fine only problem i am getting this Notice: when debug mode is on. And i shouldn't have any notices.
Notice: wpdb::prepare was called incorrectly. The query argument of wpdb::prepare() must have a placeholder.
Is there any suggestion? I know removing prepare( would take away the problem. But i want to keep the query prepared if you think its not necessary please explain.
Also adding %s, %d for first query, is good. But what for 2nd Query where i have 3 values?
Thanks in advance for reply. | *You don't need to remove the `prepare()`, but you just need to do it properly.*
And please check the `$wpdb->prepare()` [reference](https://developer.wordpress.org/reference/classes/wpdb/prepare/) for the function's syntax etc., but basically, instead of (wrapped for brevity):
```php
$insert_query = "INSERT INTO `".$computer_repair_items."`
VALUES(NULL, '".$wc_service_name."', 'services', '".$post_id."')";
$wpdb->query(
$wpdb->prepare($insert_query)
);
```
you should do it like this: (presuming `$computer_repair_items` is a valid table name)
```php
$insert_query = $wpdb->prepare(
"INSERT INTO `$computer_repair_items` VALUES(NULL, %s, 'services', %d)",
$wc_service_name, // 2nd parameter; replaces the %s (first placeholder)
$post_id // 3rd parameter; replaces the %d (second placeholder)
);
$wpdb->query( $insert_query );
```
I.e. You *must* pass at least two parameters to `$wpdb->prepare()`:
1. The **first parameter** is the SQL command and should be in the same format as accepted by the PHP's [`sprintf()`](https://www.php.net/manual/en/function.sprintf.php) function, i.e. using placeholders such as `%s` for strings and `%d` for integers.
2. The second parameter should be the replacement value for the first placeholder in the SQL command mentioned above, i.e. the first parameter. So in the example I gave, the second parameter is `$wc_service_name` which the value replaces the `%s` in the SQL command. *But note that you should **not** wrap the placeholder in quotes, so `'%s'` and `"%s"` for examples, are incorrect and just use `%s`.*
3. Depending on your SQL command, you can also have the third, fourth, fifth, etc. parameters, just as in the example I gave where I have a third parameter which is `$post_id` for the `%d` placeholder.
And actually, for **single** `INSERT` operations, you could simply use [`$wpdb->insert()`](https://developer.wordpress.org/reference/classes/wpdb/insert/):
```php
// Make sure you replace the column NAMES.
$wpdb->insert( $computer_repair_items, [
'column' => $wc_service_name,
'column2' => 'services',
'column3' => $post_id,
] );
```
For multiple inserts, you can try something like:
```php
$insert_values = [];
foreach ( [
[ 'wc_service_code', $wc_service_code ],
[ 'wc_service_id', $wc_service_id ],
[ 'wc_service_qty', $wc_service_qty ],
[ 'wc_service_price', $wc_service_price ],
] as $row ) {
$insert_values[] = $wpdb->prepare( "(NULL, %d, %s, %s)",
$order_item_id, $row[0], $row[1] );
}
$insert_query = "INSERT INTO `$computer_repair_items_meta`
VALUES " . implode( ',', $insert_values );
$wpdb->query( $insert_query );
```
Or just call `$wpdb->insert()` multiple times.. |

``` | *You don't need to remove the `prepare()`, but you just need to do it properly.*
And please check the `$wpdb->prepare()` [reference](https://developer.wordpress.org/reference/classes/wpdb/prepare/) for the function's syntax etc., but basically, instead of (wrapped for brevity):
```php
$insert_query = "INSERT INTO `".$computer_repair_items."`
VALUES(NULL, '".$wc_service_name."', 'services', '".$post_id."')";
$wpdb->query(
$wpdb->prepare($insert_query)
);
```
you should do it like this: (presuming `$computer_repair_items` is a valid table name)
```php
$insert_query = $wpdb->prepare(
"INSERT INTO `$computer_repair_items` VALUES(NULL, %s, 'services', %d)",
$wc_service_name, // 2nd parameter; replaces the %s (first placeholder)
$post_id // 3rd parameter; replaces the %d (second placeholder)
);
$wpdb->query( $insert_query );
```
I.e. You *must* pass at least two parameters to `$wpdb->prepare()`:
1. The **first parameter** is the SQL command and should be in the same format as accepted by the PHP's [`sprintf()`](https://www.php.net/manual/en/function.sprintf.php) function, i.e. using placeholders such as `%s` for strings and `%d` for integers.
2. The second parameter should be the replacement value for the first placeholder in the SQL command mentioned above, i.e. the first parameter. So in the example I gave, the second parameter is `$wc_service_name` which the value replaces the `%s` in the SQL command. *But note that you should **not** wrap the placeholder in quotes, so `'%s'` and `"%s"` for examples, are incorrect and just use `%s`.*
3. Depending on your SQL command, you can also have the third, fourth, fifth, etc. parameters, just as in the example I gave where I have a third parameter which is `$post_id` for the `%d` placeholder.
And actually, for **single** `INSERT` operations, you could simply use [`$wpdb->insert()`](https://developer.wordpress.org/reference/classes/wpdb/insert/):
```php
// Make sure you replace the column NAMES.
$wpdb->insert( $computer_repair_items, [
'column' => $wc_service_name,
'column2' => 'services',
'column3' => $post_id,
] );
```
For multiple inserts, you can try something like:
```php
$insert_values = [];
foreach ( [
[ 'wc_service_code', $wc_service_code ],
[ 'wc_service_id', $wc_service_id ],
[ 'wc_service_qty', $wc_service_qty ],
[ 'wc_service_price', $wc_service_price ],
] as $row ) {
$insert_values[] = $wpdb->prepare( "(NULL, %d, %s, %s)",
$order_item_id, $row[0], $row[1] );
}
$insert_query = "INSERT INTO `$computer_repair_items_meta`
VALUES " . implode( ',', $insert_values );
$wpdb->query( $insert_query );
```

</ol>
<p>This is my third (and hopefully final) question. I've got everything working except for saving the data in the WP database. Incidentally, <a href="https://css-tricks.com/managing-wordpress-metadata-in-gutenberg-using-a-sidebar-plugin/" rel="nofollow noreferrer">this tutorial</a> is a goldmine for an understanding of how things work in the new Gutenberg way, and how all the different pieces fit together and interact. </p>
<p>As stated previously (see links above), I'm working on customizing the featured image block in the standard post editor sidebar. Here's a screenshot of what I have:</p>
<p><a href="https://i.stack.imgur.com/s1SGB.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/s1SGB.png" alt="[FIXME]"></a></p>
<p>When you click the checkbox, the text field appears. And when you uncheck it it goes away. You can type text in the field and the page goes through all the motions of working as it should. When you save, you get a "success" message. However, nothing is being saved to the database, and that's my problem. I have independent SQL access to the DB, and there's nothing in the wp_postmeta table for any test post I create with metadata that should be saved.</p>
<p>I can click the checkbox, enter something in the text field, tab away, and see that the datastore has my information by executing the following in the debug console:</p>
<p><code>wp.data.select('core/editor').getEditedPostAttribute('meta')</code></p>
<p>which returns...
<code>Object { _featured_image_video_url: "this is a test", _featured_image_is_video: true }</code></p>
<p>as expected. But there's no joy if you save the page and look in the DB. Nothing there.</p>
<p>Here's my current JavaScript code</p>
<pre><code>const el = wp.element.createElement;
const { setState, withSelect, dispatch, select} = wp.data;
const { CheckboxControl, TextControl } = wp.components;
const { useState } = wp.element;
const { withState } = wp.compose;
const { __ } = wp.i18n;
//this replaces the default with our custom Featured Image code
wp.hooks.addFilter(
'editor.PostFeaturedImage',
'dsplugin/featured-image-as-video',
wrapPostFeaturedImage
);
//create a checkbox that takes properties
const MyCheckboxControl = (props) => {
const [ isChecked, setChecked ] = useState( false );
return(
<CheckboxControl
label={ __("Image is a video", "dsplugin") }
checked={ isChecked }
onChange={ () =>{
if (isChecked){
setChecked(false);
dispatch('core/editor').editPost({meta: {_featured_image_is_video: false}})
}else{
setChecked(true);
dispatch('core/editor').editPost({meta: {_featured_image_is_video: true}})
}
props.onChange.call();
} }
/>
)
};
// //this the std TextControl from the example in the documentation
// const MyTextControl = withState({ videoURL: '', }) (({ videoURL, setState }) => (
// <TextControl

// placeholder={ __("Enter video URL to play when clicked", "dsplugin") }
// onChange={ ( videoURL ) => {
// //update the text field
// setState( { videoURL } );
//
// //save the new value to the DB
// // meta.featured_image_video_url = videoURL;
// // withDispach( 'core/editor' ).editPost( {meta});
// } }
// />
// ) );
class MyTextControl extends wp.element.Component{
constructor(){
super()
this.state = {
videoURL: ''
}
}
render() {
const { videoURL, setState} = this.props;
// const videoURL = select('core/editor').getEditedPostAttribute('meta').featured_image_video_url;
return(
<TextControl
// select('core/editor').getEditedPostAttribute('meta').featured_image_video_url }
value={ videoURL }
placeholder={ __("Enter video URL to play when clicked", "dsplugin") }
onChange={ ( videoURL ) => {
//save the new value to the DB
const currentMeta = select( 'core/editor' ).getEditedPostAttribute( 'meta' );
const newMeta = { ...currentMeta, _featured_image_video_url: videoURL };
dispatch('core/editor').editPost({meta: newMeta})
} }
/>
)
}
};
//we put it all together in a wrapper component with a custom state to show/hide the TextControl
class MyFeaturedImageControls extends wp.element.Component{
constructor(){
super()
this.state = {
isHidden: true
}
}
toggleHidden(){
this.setState({
isHidden: !this.state.isHidden
})
}
render() {
return(
<div>
<h4>{ __("Image Options", "dsplugin") }</h4>
<MyCheckboxControl onChange={this.toggleHidden.bind(this)}/>
{ !this.state.isHidden && <MyTextControl /> }
</div>
)
}
};
//here's the function that wraps the original Featured Image content and adds
//our custom controls below
function wrapPostFeaturedImage( OriginalComponent ) {
// Get meta field information from the DB.
let meta = select( 'core/editor' ).getCurrentPostAttribute( 'meta' );
console.log ("metadata follows:");
console.log(meta);
return function( props ) {
return (
el(
wp.element.Fragment,
{},
// 'Prepend above',
el(
OriginalComponent,
props
),
<MyFeaturedImageControls />
)
);
}
}
</code></pre>
<p>And the PHP code that supports it:</p>
<pre><code>//add metadata fields for use with featured image metabox
function register_resource_item_featured_image_metadata() {
register_meta(
'post',
'_featured_image_video_url',
array(
'object_subtype' => 'ds_resource_item',
'show_in_rest' => true, #must be true to work in Guttenberg
'type' => 'string',
'single' => true,
'sanitize_callback' => 'sanitize_text_field',
'auth_callback' => function() {
return current_user_can('edit_posts');
}
)
);
register_meta(
'post',
'_featured_image_is_video',
array(
'object_subtype' => 'ds_resource_item',
'show_in_rest' => true, #must be true to work in Guttenberg
'single' => true,
// 'sanitize_callback' => 'rest_sanitize_boolean',
'type' => 'boolean',
// 'auth_callback' => function() {
// return current_user_can('edit_posts');
// }
)
);
}
add_action( 'init', 'register_resource_item_featured_image_metadata' );
</code></pre>
<p>Again... being so new to all of this, I think I'm missing some small detail. I realize my code is incomplete, and you'll see a few things commented out for debugging purposes. But as it stands, I think I should at least be saving a newly entered value to the DB based on what's there now. I also realize I still have to put code in place to fetch an initial value from the db and populate the text field. But first things first. </p>
<p>Thanks for the help.</p>
<p><strong>Update:</strong>
Here's the php code that defines the custom post type I'm using with this code:</p>
<pre><code> $args = array(
"label" => __( "Resource Items", "dstheme" ),
"labels" => $labels,
"description" => "DS Resource Items are the foundational content type for resources.",
"public" => true,
"publicly_queryable" => true,
"show_ui" => true,
"delete_with_user" => false,
"show_in_rest" => true,
"rest_base" => "dsr_item",
"rest_controller_class" => "WP_REST_Posts_Controller",
"has_archive" => false,
"show_in_menu" => true,
"show_in_nav_menus" => true,
"exclude_from_search" => false,
"capability_type" => "post",
"map_meta_cap" => true,
"hierarchical" => false,
//modify the slug below to change what shows in the URL when an DSResourceItem is accessed
"rewrite" => array( "slug" => "resource-item", "with_front" => true ),
"query_var" => true,
"menu_position" => 5,
"menu_icon" => "dashicons-images-alt2",
"supports" => array( "title", "editor", "thumbnail", "custom-fields" ),
"taxonomies" => array( "post_tag" ),
);
register_post_type( "ds_resource_item", $args );

The metadata do get saved.</h3>\n\n<p>But perhaps you'd like to try <a href=\"https://gist.github.com/5ally/d13a0d3e46aa33bc0f3f39f15d6194b7\" rel=\"nofollow noreferrer\">my code</a> which is pretty much completed, i.e. on page load, the checkbox is auto-checked/unchecked (and the text box is also shown/hidden) depending on the current <em>database</em> value. Secondly, I did it just as the Gutenberg team did it with the original <a href=\"https://github.com/WordPress/gutenberg/blob/4857ad58c1241b3d63d21a6880c989b85746c3dc/packages/editor/src/components/post-featured-image/index.js\" rel=\"nofollow noreferrer\">component for the featured image</a> and it's actually easy.. I mean, I'm just hoping you can learn some good stuff from my code. :)</p>\n\n<p>Nonetheless, regarding the question or getting your code to saving the metadata, one issue I noted before I posted the original answer, is the <code>auth_callback</code> for the <code>_featured_image_is_video</code> meta:</p>\n\n<pre class=\"lang-php prettyprint-override\"><code>register_meta(\n 'post',\n '_featured_image_is_video',\n array(\n ...\n // 'auth_callback' => function() {\n // return current_user_can('edit_posts');\n // }\n )\n);\n</code></pre>\n\n<p>Why did you comment out the <code>auth_callback</code>? Because if you do that, then it would default to <a href=\"https://developer.wordpress.org/reference/functions/__return_false/\" rel=\"nofollow noreferrer\"><code>__return_false()</code></a> for protected meta (where the name begins with <code>_</code>/underscore), which means no one is allowed to edit the meta via the REST API! :p</p>\n\n<p>So try un-commenting it out. But I'm not sure about that because if you actually had it commented in your actual code, then you would've noticed it since WordPress/Gutenberg would display a notice on the post editing screen saying the post could not be updated (because you have no permission to edit the meta or that the <code>auth_callback</code> always returns <code>false</code>).</p>\n\n<p><strong>To other readers:</strong></p>\n\n<p>Make sure your <em>custom</em> post type supports custom fields, because the REST API handbook <a href=\"https://developer.wordpress.org/rest-api/extending-the-rest-api/modifying-responses/#read-and-write-a-post-meta-field-in-post-responses\" rel=\"nofollow noreferrer\">says</a>:</p>\n\n<blockquote>\n <p>Note that for meta fields registered on custom post types, the post\n type must have <code>custom-fields</code> support. Otherwise the meta fields will\n not appear in the REST API.</p>\n</blockquote>\n\n<p>And when the meta fields do not appear in the REST API, the meta fields will not be saved/updated via the REST API.</p>\n"

The first time, is_admin() returns <strong>false</strong>, the last two times it returns <strong>true</strong>. I don't claim to know the intricacies of why that's the case, but obviously, not having the _featured_image_video_url meta variable defined the first pass through the code is a problem, and the cause of my issue with saving the variable.

Thank you very much Sally for your help in stripping away the noise so I could discover the root cause.

This is my third (and hopefully final) question. I've got everything working except for saving the data in the WP database. Incidentally, [this tutorial](https://css-tricks.com/managing-wordpress-metadata-in-gutenberg-using-a-sidebar-plugin/) is a goldmine for an understanding of how things work in the new Gutenberg way, and how all the different pieces fit together and interact.
As stated previously (see links above), I'm working on customizing the featured image block in the standard post editor sidebar. Here's a screenshot of what I have:
[![[FIXME]](https://i.stack.imgur.com/s1SGB.png)](https://i.stack.imgur.com/s1SGB.png)
When you click the checkbox, the text field appears. And when you uncheck it it goes away. You can type text in the field and the page goes through all the motions of working as it should. When you save, you get a "success" message. However, nothing is being saved to the database, and that's my problem. I have independent SQL access to the DB, and there's nothing in the wp\_postmeta table for any test post I create with metadata that should be saved.
I can click the checkbox, enter something in the text field, tab away, and see that the datastore has my information by executing the following in the debug console:
`wp.data.select('core/editor').getEditedPostAttribute('meta')`
which returns...
`Object { _featured_image_video_url: "this is a test", _featured_image_is_video: true }`
as expected. But there's no joy if you save the page and look in the DB. Nothing there.
Here's my current JavaScript code
```

I also realize I still have to put code in place to fetch an initial value from the db and populate the text field. But first things first.
Thanks for the help.
**Update:**
Here's the php code that defines the custom post type I'm using with this code:
```
$args = array(
"label" => __( "Resource Items", "dstheme" ),
"labels" => $labels,
"description" => "DS Resource Items are the foundational content type for resources.",
"public" => true,
"publicly_queryable" => true,
"show_ui" => true,
"delete_with_user" => false,
"show_in_rest" => true,
"rest_base" => "dsr_item",
"rest_controller_class" => "WP_REST_Posts_Controller",
"has_archive" => false,
"show_in_menu" => true,
"show_in_nav_menus" => true,
"exclude_from_search" => false,

//modify the slug below to change what shows in the URL when an DSResourceItem is accessed
"rewrite" => array( "slug" => "resource-item", "with_front" => true ),
"query_var" => true,
"menu_position" => 5,
"menu_icon" => "dashicons-images-alt2",
"supports" => array( "title", "editor", "thumbnail", "custom-fields" ),
"taxonomies" => array( "post_tag" ),
);
register_post_type( "ds_resource_item", $args );
``` | So I figured it out. @Sally is correct that the basic code I wrote works. However, there's one small caveat that is worth mentioning here and I'll also document a method of testing database connectivity from any post edit page **without any UI code**.
Firstly, no javascript is required for wordpress to recognize the presence of a metadata variable on an gutenberg/react-based post edit page. Only the register\_meta() call in PHP is needed. It is sufficient to put a piece of code such as the following in your plugin file for the metadata variable to exist and for a post's edit page to know how to save it to the database.
```
function register_resource_item_featured_image_metadata() {
register_meta(
'post',
'_featured_image_video_url',
array(
'object_subtype' => 'optional', #omit unless you're dealing with a custom post type
'show_in_rest' => true, #must be true to work in Guttenberg
'type' => 'string',
'single' => true,
'sanitize_callback' => 'sanitize_text_field',
'auth_callback' => function() {
return current_user_can('edit_posts');
}
)
);
}
add_action( 'init', 'register_resource_item_featured_image_metadata' );
```
With only the above, you won't have any way of setting/changing this metadata field from the WordPress UI, but you can do the following for testing purposes:
1. Edit any post (or create a new one).
2. Open the dev console on that post's edit page (right-click somewhere and **inspect element**)
3. In the console type the following and press return `wp.data.select('core/editor').getEditedPostAttribute('meta')`
This will return something like `Object { _featured_image_video_url: ""}`, which proves the system has properly registered and recognized your metadata variable, and that the DB has no value for it.
4. Now execute the following in the console: `wp.data.dispatch('core/editor').editPost({meta: {_featured_image_video_url: 'http://some_url'}})`
5. Press the **Update** button in the edit window, and wait for the page to save.
6. Re-load the page and in the console again, re-execute the first command `wp.data.select('core/editor').getEditedPostAttribute('meta')`
This time you should see `Object { _featured_image_video_url: "http://some_url"}`, which proves you've successfully saved a value to the database for that parameter. (when you re-loaded the page, wordpress fetched the metadata values for that page and stored them in memory along with the rest of the page data).
If you have a SQL server admin tool like MySQL Workbench, you can further verify this by running the following query:
`select * from wp_postmeta where post_id = 15727`
Substitute the post ID from your page's URL for the number in the query above.
```
vvvvv
(https://localhost/wp/wp-admin/post.php?post=15727&action=edit)
^^^^^
```
**My Problem**
I was doing all of this, however, I have my plugin split into two pieces. The main plugin file has all the initialization code, and at the end of the file there's an include as follows:
```
//load other plugin code a front-end user won't use if admin user
if( is_admin() ){
require plugin_dir_path( __FILE__ ) . 'admin-code.php';
}

Without thinking, I put my register\_meta() calls and their associated add\_action(), in the admin-code.php file, which only gets loaded if is\_admin() returns true. When I save a post on my system (click the Update button), the if statement above executes 3 times. The first time, is\_admin() returns **false**, the last two times it returns **true**. I don't claim to know the intricacies of why that's the case, but obviously, not having the \_featured\_image\_video\_url meta variable defined the first pass through the code is a problem, and the cause of my issue with saving the variable. If I move the register\_meta() code to a place in the file where it executes every time, everything works beautifully.
Hope this helps someone somewhere. Thank you very much Sally for your help in stripping away the noise so I could discover the root cause. Between the two of us, I think we've plugged a few gaping holes in pulling all the pieces together to enhance existing parts of the Gutenberg editor UI, at least for those that are new to React/js. |

Max | The following snippet removes the [registered site health dashboard widget](https://github.com/WordPress/WordPress/blob/5.4-branch/wp-admin/includes/dashboard.php#L56) from the dashboard. Add the code to your plugin or `functions.php` file:
```
add_action('wp_dashboard_setup', 'remove_site_health_dashboard_widget');
function remove_site_health_dashboard_widget()
{
remove_meta_box('dashboard_site_health', 'dashboard', 'normal');
}
``` |
363,064 | <p>I was thinking this might be done by adding custom CSS to a page template. I have a page template like this: </p>
<pre><code><?php
/*
* Template Name: Grafy Full Width
*/
/*add_filter('materialis_full_width_page', '__return_true');*/
materialis_get_header();
?>
<div <?php echo materialis_page_content_atts(); ?>>

<?php
while (have_posts()) : the_post();
the_content();
endwhile;
?>
</div>
</div>
<?php get_footer(); ?>
</code></pre>
<p>And I thought I might be able to add the CSS like this (basically I have 10 main tags and all I need to do is to change the header background, so I might just add 10 one-lined CSS files and condition them like this): </p>
<pre><code><?php function wpse_enqueue_page_template_styles() {
if (has_tag('Lesy')) {
wp_enqueue_style( 'Lesy', get_template_directory_uri() . '/css/Lesy.css' );
}
}
add_action( 'wp_enqueue_scripts', 'wpse_enqueue_page_template_styles' );?>

'flex-height' => true,
'wp-head-callback' => 'wp_bootstrap_starter_header_style',
) ) );
}
add_action('after_setup_theme', 'wp_bootstrap_starter_custom_header_setup', 20);
```
Renamed the method and added priority (Didn't work):
```
function wp_bootstrap_starter_custom_header_setup() {
add_theme_support( 'custom-header', apply_filters( 'wp_bootstrap_starter_custom_header_args', array(
'default-image' => '',
'default-text-color' => 'fff',
'width' => 1000,
'height' => 500,
'flex-height' => true,
'wp-head-callback' => 'wp_bootstrap_starter_header_style',
) ) );
}
add_action('after_setup_theme', 'wp_bootstrap_starter_custom_header_setup', 20);
```
Added an init action call with priority (Didn't work):
```
function wp_bootstrap_starter_custom_header_setup() {
add_theme_support( 'custom-header', apply_filters( 'wp_bootstrap_starter_custom_header_args', array(
'default-image' => '',
'default-text-color' => 'fff',
'width' => 1000,
'height' => 500,
'flex-height' => true,
'wp-head-callback' => 'wp_bootstrap_starter_header_style',
) ) );
}
add_action('after_setup_theme', 'wp_bootstrap_starter_custom_header_setup' );
add_action('init', 'wp_bootstrap_starter_custom_header_setup', 15);
```
So I've tried doing `remove_action('after_setup_theme', 'wp_bootstrap_starter_custom_header_setup');` with no results. | You can't just redeclare the function in the child theme or call `add_action` a second time. It doesn't replace it, it adds a second hook. As a result, you haven't overriden it, you've duplicated the original. Child theme overrides only work for templates.
What's more, by adding a second definition of `wp_bootstrap_starter_custom_header_setup` you've declared the function twice, which would generate a PHP fatal error. You can't have 2 functions with the same name.
So first, we need to rename your function so that there's valid PHP:
```php
function sams_custom_header_setup() {
```
Next, `add_action` adds an action. It has no concept of *replacing* an action. If you call `add_action` 5 times, the function will run 5 times.
So lets add our action for the new setup:
```php
add_action('after_setup_theme', 'sams_custom_header_setup' );
```
But remember, the original function got added too, so now both will run! So, remove the original:
```php
remove_action( 'after_setup_theme', 'wp_bootstrap_starter_custom_header_setup' );
```
TLDR:
* You can't "override" actions.
* But you can remove them and add a new action to replace them.
* Stop making multiple functions with the same name! That's invalid PHP, it'll break things
* Child themes let you override *templates* loaded via WP, not arbitrary PHP files, functions, hooks, etc
---
Edit:
It seems the function in your parent theme uses `apply_filters`, you could just filter the parameters on the `wp_bootstrap_starter_custom_header_args` filter and modify the array itself. You don't need to mess around replacing the function, or calling `add_theme_support` |

<h3>Where are the Woocommerce blocks located in Woocommerce code on Github? Answer:</h3>
<h3>As the answer underneath mentions the Woocommerce Block is a package so it is not shown on Github for the Woocommerce library but is called from: <a href="https://github.com/woocommerce/woocommerce-gutenberg-products-block/tree/master/assets/js/blocks" rel="nofollow noreferrer">https://github.com/woocommerce/woocommerce-gutenberg-products-block/tree/master/assets/js/blocks</a></h3>
<br>
<hr />
<p>If you search for adding custom attributes for Woocommerce Blocks you find a lot of WordPress examples for this.</p>
<p>For example <a href="https://wordpress.stackexchange.com/a/339151/179478">this</a>, where the answer points out, that you can add attributes by using the <code>blocks.registerBlockType</code>. But how to do this for Woocommerce Blocks?</p>
<p>I want to be able to add a data field to the HTML output. The data field should then call a product attribute and show, if it exists.</p>
<p><strong>So when you use the Woocommerce Blocks on your front page - for example the size will be shown underneath the add to cart button - as in the image.</strong></p>
<p><a href="https://i.stack.imgur.com/L3Ncy.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/L3Ncy.jpg" alt="enter image description here" /></a></p>
<p>As you might know the functionality of showing/hiding the price, add-to-cart-button, reviews are already there, when you choose a Woocommerce Block on the editing site.</p>
<p>But i havent't found the place where this functionality is created.</p>
<p><em>This would also be a great help actually - if you could show me <a href="https://github.com/woocommerce/woocommerce" rel="nofollow noreferrer">where in the Woocommerce Github library</a> the blocks are beying created. Maybe i can figure out my self how to filter through them and add the funcionality</em></p>
<p>I know - based on a Udemy course - how to create a custom plugin and create a new blog-type, save and edit.</p>
<p>But i need to figure out what Woocommerce namespace is, how they create their blocks, and what their data is called. The Woocommerce developer handbook is not saying anything about this - not what i've found.</p>
<p>I've been searching the internet for three days now, and I just don't understand that i can't seem to find ANYTHING on this. That nobody else wants to customize this functionality in Woocommerce. I know it is a new function (blocks) in the core, but still.</p>
<p>I just need to be pointed in the right direction.</p>

] | ### Edit:
### Where are the Woocommerce blocks located in Woocommerce code on Github? Answer:
### As the answer underneath mentions the Woocommerce Block is a package so it is not shown on Github for the Woocommerce library but is called from: <https://github.com/woocommerce/woocommerce-gutenberg-products-block/tree/master/assets/js/blocks>
---
If you search for adding custom attributes for Woocommerce Blocks you find a lot of WordPress examples for this.
For example [this](https://wordpress.stackexchange.com/a/339151/179478), where the answer points out, that you can add attributes by using the `blocks.registerBlockType`. But how to do this for Woocommerce Blocks?
I want to be able to add a data field to the HTML output. The data field should then call a product attribute and show, if it exists.
**So when you use the Woocommerce Blocks on your front page - for example the size will be shown underneath the add to cart button - as in the image.**
[](https://i.stack.imgur.com/L3Ncy.jpg)
As you might know the functionality of showing/hiding the price, add-to-cart-button, reviews are already there, when you choose a Woocommerce Block on the editing site.
But i havent't found the place where this functionality is created.
*This would also be a great help actually - if you could show me [where in the Woocommerce Github library](https://github.com/woocommerce/woocommerce) the blocks are beying created. Maybe i can figure out my self how to filter through them and add the funcionality*
I know - based on a Udemy course - how to create a custom plugin and create a new blog-type, save and edit.
But i need to figure out what Woocommerce namespace is, how they create their blocks, and what their data is called. The Woocommerce developer handbook is not saying anything about this - not what i've found.
I've been searching the internet for three days now, and I just don't understand that i can't seem to find ANYTHING on this. That nobody else wants to customize this functionality in Woocommerce. I know it is a new function (blocks) in the core, but still.
I just need to be pointed in the right direction. | As the blocks more more and more to front-end rendering... there's only one filter that I've been able to find for modifying the output of the blocks via PHP. [`woocommerce_blocks_product_grid_item_html`](https://github.com/woocommerce/woocommerce-gutenberg-products-block/blob/b841c53f7ec0aa01ad4cd7f0f8f1e2d338708d9b/src/BlockTypes/AbstractProductGrid.php#L329) and I'm not even sure if that will work on the All Products block which may/may not use the same code as the other products list blocks.
Here's an example that 1. removes the link and 2. adds the product's short description:
```
/**
* Add short descriptions
*
* @param string $html
* @param object $data
* @param WC_Product $product
* @return string
*/
function kia_blocks_product_grid_item_html( $html, $data, $product ) {
$short_description = $product->get_short_description() ? '<div class="wp-block-grid__short-description">' . wc_format_content( $product->get_short_description() ) . ' </div>' : '';
return
"<li class=\"wc-block-grid__product\">
{$data->image}
{$data->title}
{$data->badge}
{$data->price}
{$data->rating}" .
$short_description
. "{$data->button}
</li>";
}
add_filter( 'woocommerce_blocks_product_grid_item_html', 'kia_blocks_product_grid_item_html', 10, 3 );

363,310 | <p>I'm writing a function in functions.php. I am working with woocommerce and trying to get posts with the same cat name of product_cat on single product pages. My idea is using the cat name of woocommerce cat and get_cat_ID() to get the category ID, then use WP_query to get the posts. However, get_cat_ID() always returns 0 (I event create a category called 'test', but still). Tried to google the problem but no solution. get_cat_ID() seems to be really straightforward so I am really not sure what went wrong. It would be great if anyone can let me know what would be the possible reason.</p>
<p>To sum up my problem: I have a product_cat named 'test'. Now I want to get the ID of the category with the same name 'test'.</p>
<p>Here's the code:</p>
<pre><code>$cate_object = get_the_terms( $post->ID, 'product_cat' );
foreach( $cate_object as $cate ){

363,479 | <p>I need an unordered list, but with options selected for each list item.

``` | For people who has the same problem:
I think the problem is caused by Polylang. I checked my category list on dashboard, and realized that the category I failed to get with get\_cat\_ID() doesn't belong to any language (which is weird). I created a test category and give assign a language to it, then get\_cat\_ID() works!

Do this for your case and try to see which one is having issues.

The only fix I have produced at the moment is placing a blank `<div>` tag before `<div class="page-header mb-5">` in order to print and therefore see the styling however I feel that there is just a bug with my code and don't really want to have to rely on a blank `<div>` as a fix.
Any help?
```
<?php get_header();?>
<div class="page-header mb-5">
<h1 class="text-center"><?php the_title();?></h1>
</div>
<div class="container">
<?php if(have_posts()) : while(have_posts()) : the_post();?>
<?php the_content();?>
<?php endwhile; endif;?>
</div>
<?php get_footer();?>
``` | Let's take a look at `admin_notices`, since that's where your output is.
<https://core.trac.wordpress.org/browser/tags/5.4/src/wp-admin/admin-header.php#L281>
So, it's simply just an action-as-an-output-spot, what this means is that if you wish, you can output anything here and most importantly, this all happens in-memory, so, debugging should be pretty straight-forward; this spot is meant to output things. That's it.
Unless you're using a wrapper around this action such as <https://github.com/WPTRT/admin-notices> that allows you write your code cleaner (but this still uses the `admin_notices` action inside), you'll be doing something like `add_action( 'admin_notices', function() { echo 'My notification!' } )`
...and so will any other package that allows you to push these notifications out.
Knowing the following variables: in-memory, actions, we can attempt to see what's going out in there. You can write your own `action inspection engine` or, you can use someone else's:
<https://wordpress.org/plugins/query-monitor/>
Now, if we are to Go to our Dashboard > Open the Query Monitor Panel (it's in the top, sticky WP bar) > Access "Hooks & Actions" > Search for `admin_notices`, we'll be prompted with a screen like this:
[](https://i.stack.imgur.com/lvYzm.png)
In here, we can see exactly what's hooked to this action and their priority, so, let's try to replicate your issue. Let's create some empty notifications and output them:
```
add_action( 'admin_notices', function() {
$class = 'notice notice-error';
printf( '<div class="%1$s"><p>%2$s</p></div>', esc_attr( $class ), esc_html( '' ) );
printf( '<div class="%1$s"><p>%2$s</p></div>', esc_attr( $class ), esc_html( '' ) );
printf( '<div class="%1$s"><p>%2$s</p></div>', esc_attr( $class ), esc_html( '' ) );
printf( '<div class="%1$s"><p>%2$s</p></div>', esc_attr( $class ), esc_html( '' ) );
printf( '<div class="%1$s"><p>%2$s</p></div>', esc_attr( $class ), esc_html( '' ) );
}, 15 );
```
Great, and let's see how our dashboard looks now:

Oof. **It's broken, just like yours is**. But what does the image tell us? Well, it says that inside the theme, coming from a closure, within `functions.php` on line `87`, there are some notifications that it's trying to output.
Do this for your case and try to see which one is having issues.

Although a bit out of scope, or rather, comprising a larger scope, at times, I really wish you could get the `return value` of a hook. Your case is the prime example of inspecting how the data flows within actions isn't as easy to do, don't get me wrong, it's still possible, but requires quite some work to take care of everything and I gave up mid-way myself. In other words, wouldn't it be cool to say `Hey, WordPress, on action 'admin_notices', which one of the hooked functions returns an empty string or an error?`. Really saves you a lot of time. |

363,731 | <p>Hi so for all my Wordpress 5.4 site’s posts (articles), I'm using Yoast SEO plugin for breadcrumbs across my site.</p>
<p>For all my posts (articles) I just want:</p>
<p>Home > CategoryLink > as breadcrumbs, not the topic of the post. </p>
<p>So I’ve tried the following code in my theme's functions.php:</p>
<pre><code> add_filter( ‘wpseo_breadcrumb_links’, ‘wpseo_breadcrumb_remove_postname’ );
</code></pre>
<p>function wpseo_breadcrumb_remove_postname( $links ) {</p>
<p>if( sizeof($links) > 1 ) {</p>
<p>array_pop($links);
}</p>
<p>return $links;</p>
<p>}</p>
<p>However, what the hack above does is it also removes the previous link (parent link) and publishes only text instead of a link.</p>
<p>So if I have links as follows:</p>
<p>Home> CategoryUrl > Title of Post</p>
<p>Applying the patch into functions.php results in this:</p>
<p>Home > CategoryText</p>
<p>So the Category name is not a link anymore but a text. So breadcrumbs are useless after this hack.</p>
<p>Is there a correct way of not displaying post title in the breadcrumbs using Yoast? Thanks!</p>

] | Hi so for all my Wordpress 5.4 site’s posts (articles), I'm using Yoast SEO plugin for breadcrumbs across my site.
For all my posts (articles) I just want:
Home > CategoryLink > as breadcrumbs, not the topic of the post.
So I’ve tried the following code in my theme's functions.php:
```
add_filter( ‘wpseo_breadcrumb_links’, ‘wpseo_breadcrumb_remove_postname’ );
```
function wpseo\_breadcrumb\_remove\_postname( $links ) {
if( sizeof($links) > 1 ) {
array\_pop($links);
}
return $links;
}
However, what the hack above does is it also removes the previous link (parent link) and publishes only text instead of a link.
So if I have links as follows:
Home> CategoryUrl > Title of Post
Applying the patch into functions.php results in this:
Home > CategoryText
So the Category name is not a link anymore but a text. So breadcrumbs are useless after this hack.
Is there a correct way of not displaying post title in the breadcrumbs using Yoast? Thanks! | Let's take a look at `admin_notices`, since that's where your output is.
<https://core.trac.wordpress.org/browser/tags/5.4/src/wp-admin/admin-header.php#L281>
So, it's simply just an action-as-an-output-spot, what this means is that if you wish, you can output anything here and most importantly, this all happens in-memory, so, debugging should be pretty straight-forward; this spot is meant to output things. That's it.
Unless you're using a wrapper around this action such as <https://github.com/WPTRT/admin-notices> that allows you write your code cleaner (but this still uses the `admin_notices` action inside), you'll be doing something like `add_action( 'admin_notices', function() { echo 'My notification!' } )`
...and so will any other package that allows you to push these notifications out.
Knowing the following variables: in-memory, actions, we can attempt to see what's going out in there. You can write your own `action inspection engine` or, you can use someone else's:
<https://wordpress.org/plugins/query-monitor/>
Now, if we are to Go to our Dashboard > Open the Query Monitor Panel (it's in the top, sticky WP bar) > Access "Hooks & Actions" > Search for `admin_notices`, we'll be prompted with a screen like this:
[](https://i.stack.imgur.com/lvYzm.png)
In here, we can see exactly what's hooked to this action and their priority, so, let's try to replicate your issue. Let's create some empty notifications and output them:
```
add_action( 'admin_notices', function() {
$class = 'notice notice-error';
printf( '<div class="%1$s"><p>%2$s</p></div>', esc_attr( $class ), esc_html( '' ) );
printf( '<div class="%1$s"><p>%2$s</p></div>', esc_attr( $class ), esc_html( '' ) );
printf( '<div class="%1$s"><p>%2$s</p></div>', esc_attr( $class ), esc_html( '' ) );
printf( '<div class="%1$s"><p>%2$s</p></div>', esc_attr( $class ), esc_html( '' ) );
printf( '<div class="%1$s"><p>%2$s</p></div>', esc_attr( $class ), esc_html( '' ) );
}, 15 );
```
Great, and let's see how our dashboard looks now:
[](https://i.stack.imgur.com/yUKV9.png)
Oof. **It's broken, just like yours is**. But what does the image tell us? Well, it says that inside the theme, coming from a closure, within `functions.php` on line `87`, there are some notifications that it's trying to output.
Do this for your case and try to see which one is having issues.
---
Although a bit out of scope, or rather, comprising a larger scope, at times, I really wish you could get the `return value` of a hook. Your case is the prime example of inspecting how the data flows within actions isn't as easy to do, don't get me wrong, it's still possible, but requires quite some work to take care of everything and I gave up mid-way myself. In other words, wouldn't it be cool to say `Hey, WordPress, on action 'admin_notices', which one of the hooked functions returns an empty string or an error?`. Really saves you a lot of time. |
363,870 | <p>I have a site that reviews movies (DVD/Blu-ray, etc.)So every review in a particular category will have (Blu-ray) after the title, another will have DVD and so forth. i.e. Avengers: Infinity War (Blu-ray).

from wp_posts
where post_type in ('post', 'page', 'custom_post_type_1', 'custom_post_type_2', 'custom_post_type_n')
and post_status = 'publish'
) as p
where p.post_content not like CONCAT('%/wp-content/uploads/', DATE_FORMAT(a.post_date, '%Y/%m'), '/', a.post_name, '%')
```
Since not all attachments were embedded in the content via the media library, I cannot use:
```
select *
from wp_posts
where post_type = 'attachment'
and post_parent = 0;
```
Does anyone know a better way? My SQL query is quite slow. | What you seek isn't truly possible. You can get sort of close, but you cannot definitively say if an attachment is or isn't in use.
We can get somewhere close to a solution, but to do this we will need to process each attachment individually.
So first, get a list of all the IDs of attachments. Use a standard `WP_Query` to do this, you might even get a speed boost from object cache as a result.
Here's the official date query docs:
<https://developer.wordpress.org/reference/classes/wp_query/#date-parameters>
For each attachment:
* Check all post content and post meta for the attachments URL, with the image size removed
* Check all options and post meta for the attachments ID
* Check if the attachment has a post parent
* If any of these are true, the attachment is probably in use
Doing every attachment in a single go will be problematic, it won't be possible to run the query from a browser due to the PHP execution limit. You'd need to do attachments in batches, or via a CLI command. Preferably in batches of 100. PHP will run out of memory if you try to process all 47k at once.
However, the most effective means of testing if an attachment is in use, is to spider the entire site and save the results locally, then search the folder for the URL. Note that this won't catch things that only show once forms submit, or RSS specific stuff, things that only show to logged in users, etc |

When launching the call, I get "undefined" displayed in the alert window. What's wrong? | There are 4 filters to work with WordPress ajax.
According to your description, the following conditions are assumed
* [`wp_ajax_{$action}`](https://developer.wordpress.org/reference/hooks/wp_ajax_action/) is for running in frontend and the user is logged in
* if echo something in the php file, it will not reflect in the frontend. Javascript alert will output 'hello'
* your javascript seems to be done in PHP and generate javascript, I suppose you have added proper header
According to WP Codex, the 4 filters for ajax are
* [`wp_ajax_{$action}`](https://developer.wordpress.org/reference/hooks/wp_ajax_action/) Fires authenticated Ajax actions for logged-in users.
* [`wp_ajax_nopriv_{$action}`](https://developer.wordpress.org/reference/hooks/wp_ajax_nopriv__requestaction/) Fires non-authenticated Ajax actions for logged-out users.
* [`admin_post_{$action}`](https://developer.wordpress.org/reference/hooks/admin_post_action/) Fires on an authenticated admin post request for the given action.
* [`admin_post_nopriv_{$action}`](https://developer.wordpress.org/reference/hooks/admin_post_nopriv_action/) Fires on a non-authenticated admin post request for the given action.
Some facts about the code
* There are missing `echo` to output nonce and admin\_url
* the script is actually not working (it is according to your shared code, there might be additional code. Anyway, if going to browser inspector, it gives 400 bad request error. It did not send ajax successfully.
There are a few issues in the code, here is the fixed script with missing pieces that I need for doing the test. I put the code into my theme `functions.php` and javascript code into `test.php`
In the testing, have put in the theme functions.php
```
// load the javascript
function q364077_enqueue_scripts()
{
wp_enqueue_script('test-custom-scripts', get_theme_file_uri('/test.php'), array(), 't' . time(), true);
}
add_action('wp_enqueue_scripts', 'q364077_enqueue_scripts', 101);
// The ajax answer()
add_action( 'wp_ajax_my_action', 'answer' );
function answer() {
// check_ajax_referer( 'nonce-name' );
echo "hello";
wp_die(); // terminate script after any required work, if not, the response text will output 'hello0' because the of function return after finish
}
```
The test.php is put in the theme folder, same level as functions.php
```
<?php
// inside the javascript test.php
/** Load WordPress Bootstrap */
// for test.php in theme folders
require_once( ( ( dirname( dirname( dirname( dirname( __FILE__ ) ) ) ) ) ) . '/wp-load.php' ); // to use admin_url(), if not, the script will be broken
// for output the javascript through php
header("Content-type: text/javascript");?>
function myFunction() {
let dataContent = "hello";
let myData = {
_ajax_nonce: "<?php echo wp_create_nonce( 'nonce-name' );?>", // haven't added echo here, it is actually blank in output.
// Action Hook name for Ajax Call
action: 'my_action',
// Currently typed username
data: dataContent
};
// To send the JavaScript object to the server, convert it into a JSON string
let myDataJSON = JSON.stringify(myData);
var xhttp = new XMLHttpRequest();
xhttp.onreadystatechange = function() {
if (this.readyState == 4 && this.status == 200) {
alert(this.responseText);
}
};
let link = "<?php echo admin_url( 'admin-ajax.php' );?>"; // require "echo" to output, otherwise, it will alert unexpected output
xhttp.open("POST", link, true);
xhttp.setRequestHeader("Content-type", "application/x-www-form-urlencoded; charset=UTF-8");
// It is explained in the following, I use static value for illustration purpose
xhttp.send('_ajax_nonce=efc5e4029d&action=my_action&data=hello');
```
The data need to be serialized, not only string. Your data look likes
```
{"_ajax_nonce":"efc5e4029d","action":"my_action","data":"hello"}
```
Ajax looks for this which jQuery has done for user. For Vanilla JS, it need to be done manually or using any existing vanilla js tools.
```
_ajax_nonce=efc5e4029d&action=my_action&data=hello
```
You may test the above code by fixing the 'echo' and putting a static value of the data to experience and may also go to the inspector, Chrome as an example.
in the inspector -> Network Tab -> when you fire myFunction() in console log, it return the status to you with request/response header, in that way, it helps bug fixing.

* [`wp_ajax_{$action}`](https://developer.wordpress.org/reference/hooks/wp_ajax_action/) Fires authenticated Ajax actions for logged-in users.
* [`wp_ajax_nopriv_{$action}`](https://developer.wordpress.org/reference/hooks/wp_ajax_nopriv__requestaction/) Fires non-authenticated Ajax actions for logged-out users.
* [`admin_post_{$action}`](https://developer.wordpress.org/reference/hooks/admin_post_action/) Fires on an authenticated admin post request for the given action.
* [`admin_post_nopriv_{$action}`](https://developer.wordpress.org/reference/hooks/admin_post_nopriv_action/) Fires on a non-authenticated admin post request for the given action.
Some facts about the code
* There are missing `echo` to output nonce and admin\_url
* the script is actually not working (it is according to your shared code, there might be additional code. Anyway, if going to browser inspector, it gives 400 bad request error. It did not send ajax successfully.
There are a few issues in the code, here is the fixed script with missing pieces that I need for doing the test. I put the code into my theme `functions.php` and javascript code into `test.php`
In the testing, have put in the theme functions.php
```
// load the javascript
function q364077_enqueue_scripts()
{
wp_enqueue_script('test-custom-scripts', get_theme_file_uri('/test.php'), array(), 't' . time(), true);
}
add_action('wp_enqueue_scripts', 'q364077_enqueue_scripts', 101);
// The ajax answer()
add_action( 'wp_ajax_my_action', 'answer' );
function answer() {
// check_ajax_referer( 'nonce-name' );
echo "hello";
wp_die(); // terminate script after any required work, if not, the response text will output 'hello0' because the of function return after finish
}
```
The test.php is put in the theme folder, same level as functions.php
```
<?php
// inside the javascript test.php
/** Load WordPress Bootstrap */
// for test.php in theme folders
require_once( ( ( dirname( dirname( dirname( dirname( __FILE__ ) ) ) ) ) ) . '/wp-load.php' ); // to use admin_url(), if not, the script will be broken
// for output the javascript through php
header("Content-type: text/javascript");?>
function myFunction() {
let dataContent = "hello";
let myData = {
_ajax_nonce: "<?php echo wp_create_nonce( 'nonce-name' );?>", // haven't added echo here, it is actually blank in output.
// Action Hook name for Ajax Call
action: 'my_action',
// Currently typed username
data: dataContent
};
// To send the JavaScript object to the server, convert it into a JSON string
let myDataJSON = JSON.stringify(myData);
var xhttp = new XMLHttpRequest();
xhttp.onreadystatechange = function() {
if (this.readyState == 4 && this.status == 200) {
alert(this.responseText);
}
};
let link = "<?php echo admin_url( 'admin-ajax.php' );?>"; // require "echo" to output, otherwise, it will alert unexpected output
xhttp.open("POST", link, true);
xhttp.setRequestHeader("Content-type", "application/x-www-form-urlencoded; charset=UTF-8");
// It is explained in the following, I use static value for illustration purpose
xhttp.send('_ajax_nonce=efc5e4029d&action=my_action&data=hello');
```
The data need to be serialized, not only string. Your data look likes
```
{"_ajax_nonce":"efc5e4029d","action":"my_action","data":"hello"}
```
Ajax looks for this which jQuery has done for user. For Vanilla JS, it need to be done manually or using any existing vanilla js tools.
```
_ajax_nonce=efc5e4029d&action=my_action&data=hello
```
You may test the above code by fixing the 'echo' and putting a static value of the data to experience and may also go to the inspector, Chrome as an example.
in the inspector -> Network Tab -> when you fire myFunction() in console log, it return the status to you with request/response header, in that way, it helps bug fixing.
The above code tested and proved working in a fresh WordPress 5.3.2, default twenty twenty theme. |

Thanks! | `create_function()` is deprecated as of PHP 7.2.0, so you should avoid using it. Instead, use an [anonymous function](https://www.php.net/manual/en/functions.anonymous.php).
Additionally, it's better the check the current user role *inside* the callback function, so that the current user role is checked when the filter is applied, not when the hook is added, which could be before the current user role can be determined.

364,211 | <p>i'm adding a function in my child theme's functions.php file that will only work on a specific page. </p>
<p>i can successfully Enqueue a 3rd-party jquery script.</p>
<p>and i can successfully add my own bit of jquery/js.</p>
<p>but i'm wondering if i can add these two things within the same function wrapper.</p>
<p>so here's the part for adding the external script:</p>
<pre><code>function custom_thing () {
if(is_page( 2138 )){
wp_enqueue_script('external-script', 'http://domain.com/external/script.js', array('jquery'), 0, true);
}}
add_action( 'wp_enqueue_scripts', 'custom_thing' );
</code></pre>
<p>and here's the extra bit of code i need that goes with the external script:</p>
<pre><code>function custom_thing_addition () {
if(is_page( 2138 )){
?>
<script>
jQuery(document).ready(function($) {
$("div.specific").on('click', 'div.thing1', function () {
//do somethiing
});
});
</script>
<?php
}}
add_action( 'wp_footer', 'custom_thing_addition' );
</code></pre>
<p>can i combine these? perhaps something like this (tho this does NOT work)...</p>
<pre><code>function custom_thing () {
if(is_page( 2138 )){
wp_enqueue_script('external-script', 'http://domain.com/external/script.js', array('jquery'), 0, true);
?>
<script>
jQuery(document).ready(function($) {
$("div.specific").on('click', 'div.thing1', function () {
//do somethiing
});
});
</script>
<?php
}}
add_action( 'wp_enqueue_scripts', 'custom_thing' );
</code></pre>

] | i'm adding a function in my child theme's functions.php file that will only work on a specific page.
i can successfully Enqueue a 3rd-party jquery script.
and i can successfully add my own bit of jquery/js.
but i'm wondering if i can add these two things within the same function wrapper.
so here's the part for adding the external script:
```
function custom_thing () {
if(is_page( 2138 )){
wp_enqueue_script('external-script', 'http://domain.com/external/script.js', array('jquery'), 0, true);
}}
add_action( 'wp_enqueue_scripts', 'custom_thing' );
```
and here's the extra bit of code i need that goes with the external script:
```
function custom_thing_addition () {
if(is_page( 2138 )){
?>
<script>
jQuery(document).ready(function($) {
$("div.specific").on('click', 'div.thing1', function () {
//do somethiing
});
});
</script>
<?php
}}
add_action( 'wp_footer', 'custom_thing_addition' );
```
can i combine these? perhaps something like this (tho this does NOT work)...
```
function custom_thing () {
if(is_page( 2138 )){
wp_enqueue_script('external-script', 'http://domain.com/external/script.js', array('jquery'), 0, true);
?>
<script>
jQuery(document).ready(function($) {
$("div.specific").on('click', 'div.thing1', function () {
//do somethiing
});
});
</script>
<?php
}}
add_action( 'wp_enqueue_scripts', 'custom_thing' );
```
thanks. | The [`wp_add_inline_script()`](https://developer.wordpress.org/reference/functions/wp_add_inline_script/) is designed for this purpose. It lets you add some inline JavaScript above or below an enqueued script. You just need to pass the contents of the script, *without* `<script>` tags:
```
function custom_thing () {
if ( is_page( 2138 ) ) {
wp_enqueue_script( 'external-script', 'http://domain.com/external/script.js', array( 'jquery' ), 0, true );
wp_add_inline_script(
'external-script',
'jQuery( document ).ready( function( $ ) {
$( "div.specific" ).on( "click", "div.thing", function () {
//do somethiing
} );
} );',
'after'
);
);
}
add_action( 'wp_enqueue_scripts', 'custom_thing' );
```
The JavaScript itself is passed as a string, so just be careful about quotes. If the script is long enough that this becomes unwieldy, you'd be better off putting your JavaScript into its own file, and setting the external script as a dependency:
```
function custom_thing() {
if ( is_page( 2138 ) ) {
wp_enqueue_script( 'external-script', 'http://domain.com/external/script.js', array( 'jquery' ), 0, true );
wp_enqueue_script( 'custom-script', get_theme_file_uri( 'path/to/custom-script.js' ), array( 'jquery', 'external-script' ), 0, true );
}
}
add_action( 'wp_enqueue_scripts', 'custom_thing' );

To help make the terms easier to read, the editor will list them alphabetically, but that isn't because they're ordered alphabetically in the database. It's because a piece of javascript sorted the terms in the UI control.
There is no order, only the order you give them. Fundamentally terms have no order. Any order you see in the editor is purely circumstantial, there is no order mechanism in the database for terms.
If you want to give special meaning to a term, you need to do so explicitly, e.g. store the term ID of the significant term in post meta. You cannot rely on order, as terms do not have order. |
364,417 | <p>I'm entirely new to OOP, but trying to dip my toe in by creating a simple Recipes plugin. I have added a Recipes custom post type and a few meta fields to go along with it, and now I am trying to create a few template files for displaying the recipe meta and content. To do this, I am thinking it would be useful to create a class to get all the meta for a particular post.</p>
<p>To test, I created a template file that is meant to echo one sentence with a single meta value after the post content:</p>
<pre><code>$recipe = new Wp_Recipes_Recipe;
echo '<p>The prep time for this recipe is ' . $recipe->$recipeprep . '</p>';

$this->$recipemeta = get_post_custom($post_id);
$this->$recipeprep = $this->$recipemeta['_rcp-prep-time'][0];
}
}
</code></pre>
<p>I think I need to add some code to specify to include my new file, but I am just not sure where to put it. I have tried putting a "require_once" for the file in the load_dependencies() function in the includes folder. No matter what I try, the meta value I am trying to display does not display, and the only noticeable effect from my efforts is that the wp admin bar no longer displays.</p>
<p>I may be going about this completely the wrong way, but any guidance would be greatly appreciated! Thanks!</p>

$scripts->add_inline_script( 'lodash', 'window.lodash = _.noConflict();' );
}
```
You can also think of this as if it's inside brackets of an if statement like this.
```
$var = false;
if ( $var && $scripts->add_inline_script( '...' ) ) { // As long as $var is false PHP won't execute or check what comes after the `&&`
}
```
The line itself could be refactored to use `AND` instead of `&&` as well. This technique is sometimes used to make code "speak" English. Example:
```
$if_my_value_is_TRUE = TRUE;
$if_my_value_is_TRUE AND print "This get's printed to the screen.";
// The exact same thing with `OR` or `||`
$my_value_is_TRUE = FALSE;
$my_value_is_TRUE OR print "This get's printed to the screen.";

364,562 | <p>I have a simple piece of "hello world" code I'm trying to execute on a page. I'm adding it using a PHP snippet:</p>

] | I wanna know, what are the **hooks** in wp themes, like before\_header\_hook, after\_header\_hook?
What are the uses and benefits of these hooks in theme development? | WordPress is a whole package of different code components working together to provide a functional Content Management System. WordPress Core, Plugins, and Themes are all part of this package. Since some of these components update separately you do not want to edit the code directly, otherwise your changes will be overwritten whenever these components update. Thus, WordPress implemented a [system of Hooks](https://developer.wordpress.org/plugins/hooks/).
---
[Action hooks](https://developer.wordpress.org/plugins/hooks/actions/) allow you to inject functionality into a specific point of runtime. You can create your own plugin or theme with these action hooks so that they do not get overwritten whenever a component updates. For example, `plugins_loaded` is an action hook that runs after all plugins have been loaded during runtime. If you wanted to run specific functionality after all the plugins have been loaded during a page request you could say:
```
function example_plugins_loaded_callback() {
// Print a message then stop page request load.
print( 'All plugins have been loaded successfully!' );
exit();
}
add_action( 'plugins_loaded', 'example_plugins_loaded_callback' );
```
Once all plugins are loaded the above message gets printed to the screen and the page request stops loading additional files. This is a simple example usage but that's the gist of how action hooks work. You could call an API or write to the database at this point if you wanted to.
Without Action Hooks, if you wanted to print the above you would need edit the [`wp-settings.php`](https://core.trac.wordpress.org/browser/tags/5.4/src/wp-settings.php#L409) file directly which would eventually be overwritten whenever WordPress updates. This would break whatever functionality you would need in place when the `plugins_loaded` hook runs.
---
[Filter Hooks](https://developer.wordpress.org/plugins/hooks/filters/) allow you to modify specific values generated by functions. Unlike action hooks they expect a returned value. A good example for this is the filter hook [`the_title`](https://developer.wordpress.org/reference/hooks/the_title/) which allows you to modify `the_title()` and `get_the_title()` values before they're printed to the screen. You can view the code directly by [viewing the function on trac](https://core.trac.wordpress.org/browser/tags/5.4/src/wp-includes/post-template.php#L117). The function and callback is similar to action hooks:
```
function example_the_title_callback() {
return 'Example Title';
}
add_filter( 'the_title', 'example_the_title_callback' );
```
Using the above filter hook, anywhere that `the_title()` is called will now print `Example Title` instead.
---
Hooks also come with priorities and number of args. You will need to look up each hook to figure out what args are passed to the hook but it goes like this:
```
add_filter(
'the_title', // Hook Name
'example_the_title_callback', // Callback Function Name
10, // Priority
2 // Number of arguments
);
```
* **Hook Name** - Not every function has available hooks. You will need to look this up on a per-need basis using the [Developer Docs](https://developer.wordpress.org/reference/).
* **Callback Function** - The name of the function you want to trigger.
* **Priority** - When you want the hook to run. Hooks can have multiple functions attached to them, some may not be yours ( plugins or themes ). Lower priority will run before higher priority hooks.
* **Number of Arguments** - The arguments passed to the callback function.
Hooks that pass more than 1 argument need to be told to give your callback function those arguments. `the_title` hook passes `$title` and `$post_id`. If we want to use the `$post_id` argument we need to tell the `add_filter()` function to pass those to our callback function:
```
/**
* One Argument Hook
*/
function example_the_title_callback( $title ) {
/**
* - By default we always get 1 argument if possible.
* - We do not have access to $post_id at this point.
*/
$new_title = $title . '!!!';
return $new_title;
}
add_filter( 'the_title', 'example_the_title_callback' );
/**
* Two Arguments Hook
*/
function example_the_title_callback( $title, $post_id ) {
/**
* Since we specified 2 arguments, we receive the 2 arguments that the hook provides
*/
$post = get_post( $post_id );
$new_title = $title . ' - ' . $post->ID;
return $new_title;
}
add_filter( 'the_title', 'example_the_title_callback', 10, 2 );
```
Again, you'll need into the Developer Docs to see what arguments the hook passes.
---
Finally, you as a theme or plugin developer can add in your own custom hooks which will allow other developers to add any or modify specific functionality.
Let's say you've written a plugin that wraps the Post Title on the frontend in `<span>` HTML tags for specific styling. You can add a hook to allow other developers to add custom classes to your span like so:
```
/**
* My super cool plugin
* Add HTML span tags around titles
* Our plugin CSS can style them cool later
*/
function supercool_title( $title ) {
// Allow theme developers or plugin developers to add classes to our span tag.
$classes = apply_filters(
'supercool_title_classes', // Our custom filter name
array(), // Array of classes to pass to the filter, empty in this scenario
);
// Filters always return
return sprintf( '<span class="%s">%s</span>', esc_attr( implode( ' ', $classes ) ), $title );
}
add_filter( 'the_title', 'supercool_title' );
```
As a theme developer I can use that plugins hook to add in my own classes if I wanted to.
```
/**
* Theme Devloper modifies plugin functionality
* Adds specific class to the super cool plugin title wrapper
*/
function my_theme_supercool_title_classes( $classe ) {
$classes[] = 'special-title';
return $classes;
}
add_filter( 'supercool_title_classes', 'my_theme_supercool_title_classes' );
// Output
<span class="special-title">Post Title</span>
```
You could do the same thing with action hooks when creating your theme or plugin. WooCommerce utilizes a lot of action hooks in their templating system allowing other plugins and specific themes to add in output. Something like:
```
do_action( 'before_header_hook' ); // A custom action hook created by the developer.
```
Simply allows you, if you want to, to inject specific code at that point. Maybe an Analytics script or an entire HTML wrapper for a utility nav that the theme previously didn't support. The possibilities are endless! |

] | I started getting international visits but how do I make my site multi-language? Is there a good plugin or what do I have to do? | WordPress is a whole package of different code components working together to provide a functional Content Management System. WordPress Core, Plugins, and Themes are all part of this package. Since some of these components update separately you do not want to edit the code directly, otherwise your changes will be overwritten whenever these components update. Thus, WordPress implemented a [system of Hooks](https://developer.wordpress.org/plugins/hooks/).
---
[Action hooks](https://developer.wordpress.org/plugins/hooks/actions/) allow you to inject functionality into a specific point of runtime. You can create your own plugin or theme with these action hooks so that they do not get overwritten whenever a component updates. For example, `plugins_loaded` is an action hook that runs after all plugins have been loaded during runtime. If you wanted to run specific functionality after all the plugins have been loaded during a page request you could say:
```
function example_plugins_loaded_callback() {
// Print a message then stop page request load.
print( 'All plugins have been loaded successfully!' );
exit();
}
add_action( 'plugins_loaded', 'example_plugins_loaded_callback' );
```
Once all plugins are loaded the above message gets printed to the screen and the page request stops loading additional files. This is a simple example usage but that's the gist of how action hooks work. You could call an API or write to the database at this point if you wanted to.
Without Action Hooks, if you wanted to print the above you would need edit the [`wp-settings.php`](https://core.trac.wordpress.org/browser/tags/5.4/src/wp-settings.php#L409) file directly which would eventually be overwritten whenever WordPress updates. This would break whatever functionality you would need in place when the `plugins_loaded` hook runs.
---
[Filter Hooks](https://developer.wordpress.org/plugins/hooks/filters/) allow you to modify specific values generated by functions. Unlike action hooks they expect a returned value. A good example for this is the filter hook [`the_title`](https://developer.wordpress.org/reference/hooks/the_title/) which allows you to modify `the_title()` and `get_the_title()` values before they're printed to the screen. You can view the code directly by [viewing the function on trac](https://core.trac.wordpress.org/browser/tags/5.4/src/wp-includes/post-template.php#L117). The function and callback is similar to action hooks:
```
function example_the_title_callback() {
return 'Example Title';
}
add_filter( 'the_title', 'example_the_title_callback' );
```
Using the above filter hook, anywhere that `the_title()` is called will now print `Example Title` instead.
---
Hooks also come with priorities and number of args. You will need to look up each hook to figure out what args are passed to the hook but it goes like this:
```
add_filter(
'the_title', // Hook Name
'example_the_title_callback', // Callback Function Name
10, // Priority
2 // Number of arguments
);
```
* **Hook Name** - Not every function has available hooks. You will need to look this up on a per-need basis using the [Developer Docs](https://developer.wordpress.org/reference/).
* **Callback Function** - The name of the function you want to trigger.
* **Priority** - When you want the hook to run. Hooks can have multiple functions attached to them, some may not be yours ( plugins or themes ). Lower priority will run before higher priority hooks.
* **Number of Arguments** - The arguments passed to the callback function.
Hooks that pass more than 1 argument need to be told to give your callback function those arguments. `the_title` hook passes `$title` and `$post_id`. If we want to use the `$post_id` argument we need to tell the `add_filter()` function to pass those to our callback function:
```
/**
* One Argument Hook
*/
function example_the_title_callback( $title ) {
/**
* - By default we always get 1 argument if possible.
* - We do not have access to $post_id at this point.
*/
$new_title = $title . '!!!';
return $new_title;
}
add_filter( 'the_title', 'example_the_title_callback' );
/**
* Two Arguments Hook
*/
function example_the_title_callback( $title, $post_id ) {
/**
* Since we specified 2 arguments, we receive the 2 arguments that the hook provides
*/
$post = get_post( $post_id );
$new_title = $title . ' - ' . $post->ID;
return $new_title;
}
add_filter( 'the_title', 'example_the_title_callback', 10, 2 );
```
Again, you'll need into the Developer Docs to see what arguments the hook passes.
---
Finally, you as a theme or plugin developer can add in your own custom hooks which will allow other developers to add any or modify specific functionality.
Let's say you've written a plugin that wraps the Post Title on the frontend in `<span>` HTML tags for specific styling. You can add a hook to allow other developers to add custom classes to your span like so:
```
/**
* My super cool plugin
* Add HTML span tags around titles
* Our plugin CSS can style them cool later
*/
function supercool_title( $title ) {
// Allow theme developers or plugin developers to add classes to our span tag.
$classes = apply_filters(
'supercool_title_classes', // Our custom filter name
array(), // Array of classes to pass to the filter, empty in this scenario
);
// Filters always return
return sprintf( '<span class="%s">%s</span>', esc_attr( implode( ' ', $classes ) ), $title );
}
add_filter( 'the_title', 'supercool_title' );
```
As a theme developer I can use that plugins hook to add in my own classes if I wanted to.
```
/**
* Theme Devloper modifies plugin functionality
* Adds specific class to the super cool plugin title wrapper
*/
function my_theme_supercool_title_classes( $classe ) {
$classes[] = 'special-title';
return $classes;
}
add_filter( 'supercool_title_classes', 'my_theme_supercool_title_classes' );
// Output
<span class="special-title">Post Title</span>
```
You could do the same thing with action hooks when creating your theme or plugin. WooCommerce utilizes a lot of action hooks in their templating system allowing other plugins and specific themes to add in output. Something like:
```
do_action( 'before_header_hook' ); // A custom action hook created by the developer.
```
Simply allows you, if you want to, to inject specific code at that point. Maybe an Analytics script or an entire HTML wrapper for a utility nav that the theme previously didn't support. The possibilities are endless! |

364,875 | <p>I have this custom structure set for my permalinks: /archive/%postname%</p>
<p>With this, my URLs show as example.com/parent/child, which is the desired behavior. However, I'm adding a custom post type and this permalink structure is causing undesired URLs for the CPT. I want the permalink to be example.com/news/headline, but I'm getting example.com/archive/news/headline.</p>
<p>Here's my CPT:</p>
<pre><code> register_post_type('news', array(
...
'public' => true,
'rewrite' => array('slug' => 'news'),
'supports' => array( 'title', 'page-attributes', 'editor', 'custom-fields')
));
</code></pre>
<p>Is there a better permalink structure I could use to achieve the URLs I require? Or is there something missing/wrong in my CPT that would fix this issue?</p>

364,920 | <p>I was wondering how can I load parent theme template parts through child theme after customization. I have created three custom template for my theme and they are working fine. But now I want to load parent theme template parts layout. For example if I want edit profile page the location of the PHP file in parent theme is template_parts/layouts/profile/profile-modern.php In that folder there are other parts profile-header.php and other files. I tried to edit the profile-mordern.php directly in the parent theme and it works. But after theme update, it will be gone so I want to load that file from my child theme. I tried to search the solution but didn't get any specifically. Please can anyone help me regarding this issue? And I am learning PHP programming and WordPress theme customization so please guide me step by step if possible. And also resource link to learn. </p>
