My question: can this be done? If so, how? | As Tom J Nowell mentioned in his comment, it is not clear what do you want to accomplish. If you want to just show your empty content `div`, you can use CSS as follows:
```
div:empty {
width: 100%;
height: 20px;
margin-bottom: 10px;
background: #ff0000;
}

It will show your empty content `div` as a nice, red band. |

In your stats you see URLs of requests and not paths to files. URL has nothing to do with files on server.
Yes - if the requests targets physical file, then that file exists, but... There are plenty URLs that are not connected to any file - mod\_rewrite takes care of them. For example there is no directory like `/rss/` anywhere in your WP installation directory. There is no directory like `/category/uncaregorized/`, and yet - both of these URLs work and you can find them in stats...
I don't see anything wrong in explaining, that your client sees HTTP requests and not file paths. And these `/wp-json/*` requests are requests to WP REST API.
PS. You don't see them in Google Analytics, because there is no tracking code in REST API, so there requests are not logged to GA. But AWStats are more like server logs, so all requests get logged. |

So we need to collect the direct term ancestors when we traverse the hierarchy. The <strong>stack</strong> is a suitable data structure, where the <em>last item in</em> is the <em>first item out</em> (LIFO). In PHP 5.3+ we can use <a href=\"https://secure.php.net/manual/en/class.splstack.php\" rel=\"nofollow noreferrer\"><code>SplStack</code></a> that already implements methods like <code>pop()</code>, <code>push()</code>, <code>top()</code> and <code>count()</code>.</p>\n\n<p>By comparing the current <em>level</em> to the number of current ancestors, we can determine if we are going inner (right) or outer (left) and adjust the stack accordingly. Reducing the stack when we go left and push to the stack when we go right.</p>\n\n<p>For large import, one could run it through the <code>wp-cli</code> to avoid timeout.</p>\n\n<p>Hope you can extend this further to your needs, e.g. with a format validator and what to do with existing terms (we currently leave them unaffected here).</p>\n\n<p>Please backup before testing!</p>\n"

So we need to collect the direct term ancestors when we traverse the hierarchy. The <strong>stack</strong> is a suitable data structure, where the <em>last item in</em> is the <em>first item out</em> (LIFO). In PHP 5.3+ we can use <a href=\"https://secure.php.net/manual/en/class.splstack.php\" rel=\"nofollow noreferrer\"><code>SplStack</code></a> that already implements methods like <code>pop()</code>, <code>push()</code>, <code>top()</code> and <code>count()</code>.</p>\n\n<p>By comparing the current <em>level</em> to the number of current ancestors, we can determine if we are going inner (right) or outer (left) and adjust the stack accordingly. Reducing the stack when we go left and push to the stack when we go right.</p>\n\n<p>For large import, one could run it through the <code>wp-cli</code> to avoid timeout.</p>\n\n<p>Hope you can extend this further to your needs, e.g. with a format validator and what to do with existing terms (we currently leave them unaffected here).</p>\n\n<p>Please backup before testing!</p>\n"

can somebody tell me please what i am missing there ? | You can try using [BulkPress](https://wordpress.org/plugins/bulkpress/). It allows you to create hundreds of categories very easily. Follow these steps:
1. Install and activate the plugin.
2. In the left side bar, hover your cursor on **Bulkpress**. Then click
on **Terms**.
3. A new page will appear. In **Taxonomy** field, choose **Category**.
4. Insert your **Categories** in the **Terms** field.
5. Choose your desired **Parent**, if required.
6. Finally, click on the **Add Terms** button. |

<h3>Step 1. I need to get a pointer or id or something for the freshly added media.</h3>
<p>I don't 100% know what I am doing with WordPress itself so I do not know how to get a handle on the media I just added.</p>

] | I'm working on converting my old NucleusCMS blogs to WordPress. I have created a set of tables locally and began the conversion process. I've been fine right up to image "conversion". I think I can pull the old image and add it to the library using [this answer](https://wordpress.stackexchange.com/questions/238294/programmatically-adding-images-to-the-media-library-with-wp-generate-attachment). After that, I'm sort of lost.
What I want to do is, having just programmatically added a media item (picture), then use that image by programmatically adding it to a specific post with the dimensions and alt text I just pulled (via regex) from the source I was working from.
### Step 1. I need to get a pointer or id or something for the freshly added media.
I don't 100% know what I am doing with WordPress itself so I do not know how to get a handle on the media I just added.
### Step 2. I need to make that image be part of a post.
As for how I add it to the post (in the right size) in whatever format WordPress uses natively...
*I need help with both steps.* | Hey I used this code for something similar(I was also downloading remote image and uploading to WordPress site). Please have a look:
```
$image_url = $value;//This is the sanitized image url.
$image = pathinfo($image_url);//Extracting information into array.
$image_name = $image['basename'];
$upload_dir = wp_upload_dir();
$image_data = file_get_contents($image_url);
$unique_file_name = wp_unique_filename($upload_dir['path'], $image_name);
$filename = basename($unique_file_name);
$postarr = array(
'post_title' => $post_title,
'post_content' => $post_content,
'post_type' => 'post',//or whatever is your post type slug.
'post_status' => 'publish',
'meta_input' => array(
//If you have any meta data, that will go here.
),
);
$insert_id = wp_insert_post($postarr, true);
if (!is_wp_error($insert_id)) {
if ($image != '') {
// Check folder permission and define file location
if (wp_mkdir_p($upload_dir['path'])) {
$file = $upload_dir['path'] . '/' . $filename;
} else {
$file = $upload_dir['basedir'] . '/' . $filename;
}
// Create the image file on the server
file_put_contents($file, $image_data);
// Check image file type
$wp_filetype = wp_check_filetype($filename, null);
// Set attachment data
$attachment = array(
'post_mime_type' => $wp_filetype['type'],
'post_title' => sanitize_file_name($filename),

324,327 | <p><strong>Scenario</strong></p>
<p>I'm considering writing a custom wp-json endpoint to list ALL permalinks for everyone post in my wordpress.</p>

<h1>Current Solution</h1>
<p>I ended up writing a custom endpoint, code below:</p>
<p><em>added to the bottom of functions.php</em></p>
<pre><code>function get_all_slugs() {
$posts = get_posts( array(
'numberposts' => -1,
'post_type' => "screen",
) );
if ( empty( $posts ) ) {
return null;
}
$posts_data = array();
foreach( $posts as $post ) {
$id = $post->ID;
$posts_data[] = (object) array(
'id' => $id,
'slug' => $post->post_name,
//'title' => $post->post_title,
);
}
return $posts_data;
}
add_action( 'rest_api_init', function () {
register_rest_route( 'row/v1', '/all-slugs', array( // /(?P<post_type>\d+)', array(
'methods' => 'GET',
'callback' => 'get_all_slugs',
) );
} );

] | **Scenario**
I'm considering writing a custom wp-json endpoint to list ALL permalinks for everyone post in my wordpress.
**Question**
Is it possible to do this with a rest query + filters? eg. [http://wpsite.com/wp-json/wp/v2/posts?filter[only-permalinks]](http://wpsite.com/wp-json/wp/v2/posts?filter%5Bonly-permalinks%5D)
Current Solution
================
I ended up writing a custom endpoint, code below:
*added to the bottom of functions.php*
```
function get_all_slugs() {
$posts = get_posts( array(
'numberposts' => -1,
'post_type' => "screen",
) );
if ( empty( $posts ) ) {
return null;
}
$posts_data = array();
foreach( $posts as $post ) {
$id = $post->ID;
$posts_data[] = (object) array(
'id' => $id,
'slug' => $post->post_name,
//'title' => $post->post_title,
);
}
return $posts_data;
}
add_action( 'rest_api_init', function () {
register_rest_route( 'row/v1', '/all-slugs', array( // /(?P<post_type>\d+)', array(
'methods' => 'GET',
'callback' => 'get_all_slugs',
) );
} );

Yes, since 4.9.8 (see [#43874](https://core.trac.wordpress.org/ticket/43874)) it's possible to render only fields needed with the `_fields` parameter.
Examples
--------
Render only the *permalinks*:
<https://example.com/wp-json/wp/v2/posts?_fields=link>
```
[
{
link: "https://example.com/foo/"
},
{
link: "https://example.com/bar/"
},
]
```
Render only the *post IDs* and *permalinks*:
<https://example.com/wp-json/wp/v2/posts?_fields=id,link>
```
[
{
id: 123,
link: "https://example.com/foo/"
},
{
id: 234,
link: "https://example.com/bar/"
},
]
```
Render only the *post IDs* and the *slugs*:
<https://example.com/wp-json/wp/v2/posts?_fields=id,slug>
```
[
{
id: 123,
slug: "foo"
},
{
id: 234,
slug: "bar"
},
]
```
Fetching All Available Items
----------------------------
Currently we have to fetch all available items with paging, like:
```
https://example.comwp-json/wp/v2/posts?_fields=slug&per_page=100&page=1
https://example.comwp-json/wp/v2/posts?_fields=slug&per_page=100&page=2
...
```
where `per_page` is 10 by default and with maximum value of 100.
Fetching all items in a single request can result in fatal errors if the number of items exceeds the available resources.
The ticket [#43998](https://core.trac.wordpress.org/ticket/43998) to allow unbound requests (something like `per_page=-1`) for logged in users, was closed as *wontfix* because it doesn't scale and has performance issues.
There's a ticket [#45140](https://core.trac.wordpress.org/ticket/45140) to increase the upper bound for `per_page` to few hundreds.
Usually there's no need to display so many items in a user interface and there exists javascript techniques to handle the pagination.
If more is really needed then one could filter the rest query via `rest_{$post_type}_query` to override the maximum default value of `posts_per_page`, at the risk of fatal errors if available resources are exceeded. |

If you want to redirect from HTTP then you need to check that the request was for HTTP before redirecting to HTTPS. For example:
```
RewriteCond %{HTTPS} off
RewriteRule (.*) https://%{HTTP_HOST}/$1 [R=301,L]
```
No need for the `NC` flag, as you are simply matching everything anyway.

That function needs to already be loaded in the current sequence. As long as whatever file that contains your custom function is loaded at the time the action/filter is triggered, then your function can run (because it is in memory at that time) - otherwise, you'll get an error since that function will be undefined.</p>\n\n<p>Here's a practical discussion of what I'm talking about. If you apply something in your theme's functions.php file that is hooked to <code>plugins_loaded</code>, your function will never fire (even though it's right there in functions.php) because the action has already passed by the time the functions.php file is loaded. You need a later action.</p>\n\n<p>Or another example would that you need to make sure the file containing your function is actually loaded so that when your action or filter call is triggered that the file containing the function is loaded into memory. For example, if you have developed a plugin that consists of multiple files and in the main plugin file that gets loaded has a filter that triggers \"<code>my_cool_filter_function()</code>\" but you never bothered to <code>include()</code> or <code>require()</code> that file in your sequence, then the function will throw an undefined error because the function does not exist when the filter is triggered. However, as long as you've run <code>include()</code> (or <code>require()</code>) to load that file, then you'll be fine because <code>my_cool_filter_function()</code> will be available to be run.</p>\n"

] | When trying to edit a wordpress post (page) the editor loads indefinitely, console shows JS error with post.php / polyfill, see code below. To me it seems to be a typo and I have no idea where the line is injected so I could change it manually.
Disabling all plugins did not change anything, neither did disabling Gutenberg. I am not much of a coder, nevertheless it seems to me there should not be a double quotation mark after the last 'defer"... in the line of code.
I am running WP 5.0.2 on Apache (Domainfactory) in a managed server environment, Theme is Enfold by Kriesi. Re-installing Wordpress and the theme (copied from working installations) changed nothing so far.
The reported error in the console is
"Uncaught SyntaxError: missing ) after argument list"
in
<https://.../wp-admin/post.php?post=23&action=edit&lang=de&classic-editor=1:238>
There it says
```
( 'fetch' in window ) || document.write( '<script src="https://12345678-123.ch/wp-includes/js/dist/vendor/wp-polyfill-fetch.min.js?ver=3.0.0' defer='defer"></scr' + 'ipt>' );( document.contains ) || document.write( '<script src="https://12345678-123.ch/wp-includes/js/dist/vendor/wp-polyfill-node-contains.min.js?ver=3.26.0-0' defer='defer"></scr' + 'ipt>' );( window.FormData && window.FormData.prototype.keys ) || document.write( '<script src="https://12345678-123.ch/wp-includes/js/dist/vendor/wp-polyfill-formdata.min.js?ver=3.0.12' defer='defer"></scr' + 'ipt>' );( Element.prototype.matches && Element.prototype.closest ) || document.write( '<script src="https://12345678-123.ch/wp-includes/js/dist/vendor/wp-polyfill-element-closest.min.js?ver=2.0.2' defer='defer"></scr' + 'ipt>' );
```
Any idea would be much appreciated. | Here is an answer: [WordPress v5.0.3 Gutenberg & JS error "Uncaught SyntaxError: missing ) after argument list"](https://wordpress.stackexchange.com/questions/325570/wordpress-v5-0-3-gutenberg-js-error-uncaught-syntaxerror-missing-after-arg)
The simplest way: Find & delete PHP Hook which added 'defer' to script (in the function.php file). Or if you have skills you can edit the code of the hook. Reason: Confusion/conflict with quotes (' & ") witch break down JS.
About 'defer' you can read here: <https://www.w3schools.com/tags/att_script_defer.asp> This is probably due to speed optimization on your website. |

324,908 | <p>I have been follow a tutorial here: <a href="https://rudrastyh.com/gutenberg/remove-default-blocks.html" rel="noreferrer">https://rudrastyh.com/gutenberg/remove-default-blocks.html</a> Where it discusses how to remove default Gutenberg blocks like so:</p>
<pre><code>add_filter( 'allowed_block_types', 'misha_allowed_block_types', 10, 2 );
function misha_allowed_block_types( $allowed_blocks, $post ) {
$allowed_blocks = array(
'core/image',
'core/paragraph',
'core/heading',
'core/list'
);
if( $post->post_type === 'page' ) {
$allowed_blocks[] = 'core/shortcode';
}
return $allowed_blocks;
}
</code></pre>
<p>So what this is doing is limiting the default Gutenberg blocks to image, paragraph, heading, and list. I then set the page post type to also allow for the shortcode block. So this works fine, but I am now having an issue where it removes the functionality of reusable blocks and I can't figure out what needs to be added to add that functionality back.</p>
<p>I tried commenting on that article, but the author wasn't able to think of a solution currently. I was wondering if anyone had any ideas on adding the reusable block functionality back after adding the above code snippet?</p>

] | I have been follow a tutorial here: <https://rudrastyh.com/gutenberg/remove-default-blocks.html> Where it discusses how to remove default Gutenberg blocks like so:
```
add_filter( 'allowed_block_types', 'misha_allowed_block_types', 10, 2 );
function misha_allowed_block_types( $allowed_blocks, $post ) {
$allowed_blocks = array(
'core/image',
'core/paragraph',
'core/heading',
'core/list'
);
if( $post->post_type === 'page' ) {
$allowed_blocks[] = 'core/shortcode';
}
return $allowed_blocks;
}
```
So what this is doing is limiting the default Gutenberg blocks to image, paragraph, heading, and list. I then set the page post type to also allow for the shortcode block. So this works fine, but I am now having an issue where it removes the functionality of reusable blocks and I can't figure out what needs to be added to add that functionality back.
I tried commenting on that article, but the author wasn't able to think of a solution currently. I was wondering if anyone had any ideas on adding the reusable block functionality back after adding the above code snippet? | The *reusable block* is registered with the `core/block` name.
I tried to add it to the *allowed blocks* in the `allowed_block_types` filter, here's an example:
```
add_filter( 'allowed_block_types', 'wpse324908_allowed_block_types', 10, 2 );
function wpse324908_allowed_block_types( $allowed_blocks, $post ) {
$allowed_blocks = array(
'core/block', // <-- Include to show reusable blocks in the block inserter.
'core/image',
'core/paragraph',
);
return $allowed_blocks;
}
```
and it showed the *reusable blocks* within the *block inserter*, if at least two other blocks were included as well:
[](https://i.stack.imgur.com/4hbq7.png)
Looking at the `/wp-includes/js/dist/editor.js` we can e.g. see this check for `core/block` regarding including reusable blocks in the block inserter:
```
var selectors_canIncludeReusableBlockInInserter = function canIncludeReusableBlockInInserter(state, reusableBlock, rootClientId) {
if (!selectors_canInsertBlockTypeUnmemoized(state, 'core/block', rootClientId)) {
return false;
}

] | I have a wordpress website in which I have a specific page for dictionary. This page is actually a custom page and does these things:
* `site.com/dictionary` lists all the words
* `site.com/dictionary/?w=word` shows the definition of the word
now I want the URL to be cleaned up and becomes like this:
```
site.com/dictionary/word
```
I have made these lines in `.htaccess` but I get `404` error:
```
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /dictionary/
RewriteRule (.*) ?w=$1 [L]
</IfModule>
```
May you help me with this?
update:
I have tried the solution here: <https://stackoverflow.com/questions/27162489/> but this also didn't work for me. | You can do this with the internal rewrite system, which is parsed in php, not htaccess.
First, add the rule. This assumes you have created a root page under `Pages` with the slug `dictionary`.
```
function wpd_dictionary_rewrite(){
add_rewrite_tag( '%dictionary_word%', '([^/]+)' );
add_rewrite_rule(
'^dictionary/([^/]+)/?$',
'index.php?pagename=dictionary&dictionary_word=$matches[1]',
'top'
);
}
add_action( 'init', 'wpd_dictionary_rewrite' );
```
This code would go in your theme's `functions.php` file, or your own plugin.
Visit the `Settings > Permalinks` page to flush rules after adding this.
Now you can visit `site.com/dictionary/word` and the requested word will be available in the template with `get_query_var('dictionary_word')`.
If the code relies on `$_GET['w']` and you can't / don't want to change this, you can hook before the code runs and set the value manually:
```
function wpd_set_dictionary_word(){
if( false !== get_query_var( 'dictionary_word', false ) ){
$_GET['w'] = get_query_var( 'dictionary_word' );
}
}
add_action( 'wp', 'wpd_set_dictionary_word' );

324,970 | <p>I was looking for a clean way to group my search results by posttype. I currently have 3 post types: <em>Page</em>, <em>Post</em> and <em>Glossary</em>.

324,979 | <p>I've registered a sidebar component in the block editor. I'd like to access the <code>state</code> of the component (<code>MyPlugin</code>) from outside of that component, in some arbitrary JavaScript in the same file. Is it possible to access the state via e.g. the <code>wp</code> object?</p>
<p>Or, is it possible, and would it be better to do this using <code>props</code>?</p>
<pre><code>class MyPlugin extends Component {
constructor() {
super( ...arguments );
// initial state
this.state = {
key: 'my_key',
value: ''
}
}
render() {
return el(
PluginPostStatusInfo,
{
className: 'my-panel-class'
},
el(
TextControl,
{
name: 'my_text_control_name',
label: __( 'My label', 'my-text-domain' ),
value: this.state.value,
onChange: ( value ) => {
this.setState( {
value
})
}
}
)
);
}
}
registerPlugin( 'my-plugin', {
render: MyPlugin
} );
const myFunction = () => {
// this function is hooked into an action elsewhere,
// and needs to access the state of MyPlugin
}
</code></pre>
<p>What I'd ultimately like to do is access the textbox's value from a separate function. I don't mind how this is achieved, e.g. with <code>state</code> or <code>props</code> or some other means. I guess another approach would be to have the component write its value into a global variable when it changes, but that seems a bit clunky.</p>

] | I've registered a sidebar component in the block editor. I'd like to access the `state` of the component (`MyPlugin`) from outside of that component, in some arbitrary JavaScript in the same file. Is it possible to access the state via e.g. the `wp` object?
Or, is it possible, and would it be better to do this using `props`?
```
class MyPlugin extends Component {
constructor() {
super( ...arguments );
// initial state
this.state = {
key: 'my_key',
value: ''
}
}
render() {
return el(
PluginPostStatusInfo,
{
className: 'my-panel-class'
},
el(
TextControl,
{
name: 'my_text_control_name',
label: __( 'My label', 'my-text-domain' ),
value: this.state.value,
onChange: ( value ) => {
this.setState( {
value
})
}
}
)
);
}
}
registerPlugin( 'my-plugin', {
render: MyPlugin
} );
const myFunction = () => {
// this function is hooked into an action elsewhere,
// and needs to access the state of MyPlugin
}
```
What I'd ultimately like to do is access the textbox's value from a separate function. I don't mind how this is achieved, e.g. with `state` or `props` or some other means. I guess another approach would be to have the component write its value into a global variable when it changes, but that seems a bit clunky. | To do so you need to use a redux store. To register your own you can follow the steps in the [documentation](https://github.com/WordPress/gutenberg/tree/master/packages/data). Here is the minimum that should achieve what you are looking for.
First, lets give the "shape" of the store in the initial state object:
```
const initial_state = {
my_control: {
value: ""
},
};
```
Lets create a reducer that manipulates the state:
```
const reducer = (state = initial_state, action) => {
switch (action.type) {
case "UPDATE_MY_CONTROL_VALUE": {
return {
...state,
my_control: {
...state.my_control,
value: action.value
}
};
}
}
return state;
};
```
As you can see, we set the `initial_state` object we just created as the default value of the state.
Now lets add an action which updates the store, sending data to the reducer:
```
const actions = {
updateMyControlValue(value) {
return {
type: "UPDATE_MY_CONTROL_VALUE",
value
};
},
}
```
Lets add a selector that gets the data from the store:
```
const selectors = {
getMyControlValue(state) {
return state.my_control.value;
},
};
```
And now we will register the store with the previous constants:
```
const { registerStore } = wp.data;
registerStore("my_plugin/my_store", {
reducer,
actions,
selectors
});
```
Now the store is registered. We will connect the component to the store to get the latest value of my\_control and to update it:
```
const { Component } = wp.element;
const { TextControl } = wp.components;
const { compose } = wp.compose;
const { withDispatch, withSelect } = wp.data;
class Text extends Component {
render() {
const { value, updateMyControlValue } = this.props;
return (
<TextControl
value={value}
onChange={updateMyControlValue}
/>
);
}
}
export default compose([
withDispatch((dispatch, props) => {
// This function here is the action we created before.
const { updateMyControlValue } = dispatch("my_plugin/my_store");
return {
updateMyControlValue
};
}),
withSelect((select, props) => {
// This function here is the selector we created before.
const { getMyControlValue } = select("my_plugin/my_store");
return {
value: getMyControlValue()
};
}),
])(Text);
```
---
This is a simple example, but you can take a look at the link on the documentation to see how you can use other functionality to enhance the store (for example, with controls and resolvers).
Also you can make use the [core stores](https://github.com/WordPress/gutenberg/tree/master/docs/designers-developers/developers/data) and their selectors and actions inside your component's `withSelect` and `withDispatch`. |
325,001 | <p>I would really like to keep my template files as clean as possible, without including too much argument data. Is it possible with the following example...</p>
<pre><code> $args = array(
'theme_location' => 'main-menu',
'menu_class' => 'list-inline',
'add_li_class' => 'list-inline-item'
);
wp_nav_menu($args);
</code></pre>
<p>...that I can store my array of arguments in a function within my functions.php file, and then simply call the argument data onto my header.php where my wp_nav_menu() lives? Please feel free to correct me if I am wrong, but is this a good time for me to use a add_action/do_action for this specific case?</p>
<p>I want to use my functions.php file as a one-stop-shop to (i.e. register the nav, add basic or advanced argument data to the same nav, etc..). </p>
<p>This is the first time I'm thinking about this, so I'm all for any best practices.</p>

] | I am trying to query a custom taxonomy terms in a way that keeps the hierarchical structure.
Here is the code that I am using..
```
function ev_test_data() {
$title = 'Mens Levi\'s Jeans';
$titles = str_replace( array("'", '"', '-', '\\' ), '', explode( ' ', trim($title)) );
$cats = array();
foreach ( $titles as $kw ) {
$terms = get_terms( array(
'taxonomy' => 'product_cat',
'orderby' => 'parent', // I guess this is where I am lost.
'hide_empty' => false,
'name__like' => $kw,
) );
foreach ( $terms as $term ) {
$cats[] = $term->term_id;
}
}
$finals = array();
foreach ( $cats as $cat ) {
$catobj = get_term_by( 'id', $cat, 'product_cat' );
$tree = '';
$ancentors = array_reverse(get_ancestors( $cat, 'product_cat', 'taxonomy' ), true);
$i=1;
foreach ( $ancentors as $ancentor ) {
$sterm = get_term_by( 'id', $ancentor, 'product_cat' );
$tree .= $i == 1 ? '<b>' . $sterm->name . '</b>' : ' > ' . $sterm->name;
$i++;
}
$tree .= ' > ' . $catobj->name;
$finals[$cat] = $tree;
}
echo '<pre>' . print_r( $finals, true ) . '</pre>';
}
```
This produces this list.
```
Array
(
[4638] => Fashion > Womens Clothing
[4699] => Fashion > Womens Handbags & Bags
[4709] => Fashion > Womens Shoes
[4461] => Fashion > Mens Accessories
[4493] => Fashion > Mens Clothing
[4512] => Fashion > Mens Shoes
[4603] => Fashion > Womens Accessories
[4779] => Fashion > Vintage > Mens Vintage Clothing
[4821] => Fashion > Vintage > Womens Vintage Clothing
[4290] => Fashion > Kids Clothing, Shoes & Accs > Boys Clothing (Sizes 4 & Up) > Jeans
[4319] => Fashion > Kids Clothing, Shoes & Accs > Girls Clothing (Sizes 4 & Up) > Jeans
[4354] => Fashion > Kids Clothing, Shoes & Accs > Unisex Clothing > Jeans
[4500] => Fashion > Mens Clothing > Jeans
[4660] => Fashion > Womens Clothing > Jeans
[4666] => Fashion > Womens Clothing > Maternity > Jeans
)
```
However, this list is not ordered as I want. I need it to be ordered by the hierarchical order. Something like this.
```
Array
(
[4493] => Fashion > Mens Clothing
[4500] => Fashion > Mens Clothing > Jeans
[4638] => Fashion > Womens Clothing
[4660] => Fashion > Womens Clothing > Jeans
[4666] => Fashion > Womens Clothing > Maternity > Jeans
[4699] => Fashion > Womens Handbags & Bags
[4709] => Fashion > Womens Shoes
[4603] => Fashion > Womens Accessories
[4512] => Fashion > Mens Shoes
[4461] => Fashion > Mens Accessories
[4779] => Fashion > Vintage > Mens Vintage Clothing
[4821] => Fashion > Vintage > Womens Vintage Clothing
[4290] => Fashion > Kids Clothing, Shoes & Accs > Boys Clothing (Sizes 4 & Up) > Jeans
[4319] => Fashion > Kids Clothing, Shoes & Accs > Girls Clothing (Sizes 4 & Up) > Jeans
[4354] => Fashion > Kids Clothing, Shoes & Accs > Unisex Clothing > Jeans
)
```
Can this be done using WordPress built in functions? If not, what would be the logic for the custom query? I am not asking to do it for me, but any help or guide or headstart would be great.
Thanks | I was looking for the same thing and think this should work for you : [Custom taxonomy, get\_the\_terms, listing in order of parent > child](https://wordpress.stackexchange.com/questions/37285/custom-taxonomy-get-the-terms-listing-in-order-of-parent-child) |

Thanks. | It's not clearly stated in your question, but I guess, you added exactly this code to the widget file:
```
<?php echo $wp_query->current_post +1; ?>
```
Am I right?
If so, then it couldn't work, because this code takes the counter from global `$wp_query` object, but... This widget doesn't use global `$wp_query` and uses custom `WP_Query` instance. You can see it clearly here: <https://github.com/WordPress/WordPress/blob/master/wp-includes/widgets/class-wp-widget-recent-posts.php#L70>.
And even worse (in this case), because this widget doesn't use `the_post` method and standard way of looping through posts, but native PHP `foreach` loop (<https://github.com/WordPress/WordPress/blob/master/wp-includes/widgets/class-wp-widget-recent-posts.php#L94>), to be more efficient. But this also means that this loop doesn't change the counter value...
But... There is one more, major, but.
You should never ever modify core WP files. If you do this, you won't be able to update your WP or you will loose these modifications. You can easily cause any plugin or theme to work incorrectly.
So...? Is that it? It can't be done?
------------------------------------
Well, it can. If all you want to do is to add numbers in the `li` element, you can do it with CSS.
One way would be to change the `list-style-type` to `decimal` for list in that widget:
```
.widget_recent_entries ul {list-style-type: decimal;}
```
Another way is to use `:before` pseudo-class with counter:
```
.widget_recent_entries ul {
counter-reset: my-recent-posts-widget-counter;
}
.widget_recent_entries ul li {
counter-increment: my-recent-posts-widget-counter;
}
.widget_recent_entries ul li {
content: counter(my-recent-posts-widget-counter);
}

``` | So,
I was researching this topic a bit deeper. All answers found on this SE suggested disabling Gutenberg with a plugin. This couldn't be a valid "fix" in my oppinion.
After researching and browsing through the git issues of `WordPress/gutenberg` I've found a pretty easy solution for this problem.
The user `joshuafredrickson` on the git suggested changing the args of the custom post type array from `'public' => false,` to **true**.
I have checked that fix on multiple of my clients projects and it has worked every single time.

<p>I nearly solved all of my mixed content issues, but the mixed content warnings of the Wordpress plugin kk star ratings are still unsolved.</p>

<p>Could these lines be responsible for the mixed content warning?</p>

] | I recently switched to ssl in order to provide a better and more secure website experience for my users.
I nearly solved all of my mixed content issues, but the mixed content warnings of the Wordpress plugin kk star ratings are still unsolved.
When I open a blog post, I always get the following notifications:
**The following content is displayed in an insecure manner.**
/wp-content/plugins/kk-star-ratings/yellow.png.
/wp-content/plugins/kk-star-ratings/gray.png.
I've already looked into the plugin folder, but I don't have any php knowledge to fix it.
Could these lines be responsible for the mixed content warning?
```
echo $star_gray ? '.kk-star-ratings .kksr-star.gray { background-image: url('.$star_gray.'); }' : '';
echo $star_yellow ? '.kk-star-ratings .kksr-star.yellow { background-image: url('.$star_yellow.'); }' : '';
echo $star_orange ? '.kk-star-ratings .kksr-star.orange { background-image: url('.$star_orange.'); }' : '';
```
I would be grateful if someone could help me to load these files via ssl. | I solved it myself. You have to remove the stars in settings / stars. Afterwards the tool recognizes ssl and will load it from a secure version of the website. |

Thank you so much! | If you wanted to remove all colorful text from your site, you could use a global CSS rule, as in
```
* {color:black !important; background-color:white !important}
```
which should turn all text to black on white background. (The '\*" should apply to all CSS elements.) That wouldn't get rid of images or other things, so you might add this for images
```
img {display:none !important;}
```
And then add additional elements as needed.
The problem with this is that it would affect the entire site, so you would need to have a way to change the theme on the fly just for the text-only users. That's not easy to do, I think.
Maybe create another WP installation that uses the same database, but set up a theme for that new site that adds the above CSS and others as needed. The new site would be at <https://www.example.com/textonly> , for example. You'd also need to copy the plugins folder to the new site.
Probably some additional tweaks needed, but that might get you started.
**Added**
As I think about the duplicate site/same database idea, with the duplicate site using a different theme, there might be an issue.
The active theme is stored in wp-options table (I think), so a shared database couldn't have a different theme.
So you would need to use a hook to change the theme name (and location) during the very first part of the page load process. You would still need a separate install with the shared database, but the hook would load a different theme.
Perhaps function that uses a hook that would change the theme name (and location) is all that is needed. The hook would look at the page's query parameter (say <https://www.example.com/some-page?theme=textonly> )and inspect the 'theme' query parameter to decide which theme to load.
I don't think that a query parameter that specifies a theme name is available in WP core - although that would be a great idea; very useful for testing new themes on an active site, which some people would like to do.
But perhaps my random thoughts might get you going into a direction that will meet your needs. I'd be interested in other thoughts about this.
**Added More**
So, digging around possible hooks, I came up with the '`setup_theme`' hook, in the wp-settings.php around line 407. A bit later in that file (around line 438) (line numbers are there from my copy/paste from the code):
```
// Load the functions for the active theme, for both parent and child theme if applicable.
439 if ( ! wp_installing() || 'wp-activate.php' === $pagenow ) {
440 if ( TEMPLATEPATH !== STYLESHEETPATH && file_exists( STYLESHEETPATH . '/functions.php' ) )
441 include( STYLESHEETPATH . '/functions.php' );
442 if ( file_exists( TEMPLATEPATH . '/functions.php' ) )
443 include( TEMPLATEPATH . '/functions.php' );
444 }
```
So, it would seem that by changing the `TEMPLATEPATH` and `STYLESHEETPATH` constants, we could change the theme being used.
So, psuedocode:
```
add_action('setup_theme', 'my_use_different_theme');
function my_use_different_theme() {
TEMPLATEPATH = "path/to/the/other/theme/templates';
STYLESHEETPATH = "path/to/the/other/theme/styles";
return;
}
```
Might allow you to create a function that would add the action if the query parameter contained a value like '`theme=newtheme`', where '`newtheme`' is name of the theme you want to use. Psuedocode:
```
$themename = "get/the/query/value";
if ($themename =='newtheme') {
add_action('setup_theme', 'my_use_different_theme');
}
```
which would call our '`my_use_different_theme`' function if the query parameter for the page was `theme=newtheme` . |

"https://wordpress.stackexchange.com/questions/325271",
"https://wordpress.stackexchange.com",
"https://wordpress.stackexchange.com/users/128304/"
] | I have an ACF-field, that gives an output like this:
```
<p>Lorem ipsum dolor sit amet, consectetur adipiscing elit.</p>
<p><img class="alignnone size-large wp-image-48" src="http://example.org/wp-content/uploads/2019/01/foo-bar.jpg" alt="" width="1024" height="640" /></p>
<p>Sed lacinia enim a <strong>est aliquet</strong>, et accumsan ex pellentesque. </p>
<p>Adipiscing elit, lorem ipsum dolor sit amet, consectetur.</p>
```
... Both images and text.
With [wp\_html\_excerpt](https://codex.wordpress.org/Function_Reference/wp_html_excerpt) I can remove all tags, so I get one long text-blurp.
But with WordPress' native excerpts, then it doesn't remove line-breaks or bold text, which I find nice.
How would I go about achieving, getting an excerpt like that, from my ACF-wysiwyg-field?
So ideally, I would call my function like this: `create_neat_excerpt( $html, 15 );` and get an output like this (from above-given input):
```
<p>Lorem ipsum dolor sit amet, consectetur adipiscing elit.</p>
<p>Sed lacinia enim a <strong>est aliquet</strong>, et accumsan...</p>
```
Addition: My current attempt
----------------------------
```
$project_desc = get_field( 'project_description' );
if( !empty( $project_desc ) ):
$trimmed_text = wp_html_excerpt( $project_desc, 800 );
$last_space = strrpos( $trimmed_text, ' ' );
$modified_trimmed_text = substr( $trimmed_text, 0, $last_space );
echo $modified_trimmed_text . '...';
endif;
``` | You can provide your own implementation of `wp_trim_excerpt` which is responsible for trimming and stripping HTML tags (it uses `wp_strip_all_tags`),
By copying the function source code and applying the change that you want (which is keeping the `<p>` and `<strong>` tags (or any additional tags as you wish) and it will work nicely.
I copied the function for you and applied the change of allowing `<p>` and `<strong>` to be on your final excerpt. **(You should put this code in your `functions.php` file)**
```
function wp_trim_excerpt_modified($text, $content_length = 55, $remove_breaks = false) {
if ( '' != $text ) {
$text = strip_shortcodes( $text );
$text = excerpt_remove_blocks( $text );
$text = apply_filters( 'the_content', $text );
$text = str_replace(']]>', ']]>', $text);
$num_words = $content_length;
$more = $excerpt_more ? $excerpt_more : null;
if ( null === $more ) {
$more = __( '…' );
}
$original_text = $text;
$text = preg_replace( '@<(script|style)[^>]*?>.*?</\\1>@si', '', $text );
// Here is our modification
// Allow <p> and <strong>
$text = strip_tags($text, '<p>,<strong>');
if ( $remove_breaks )
$text = preg_replace('/[\r\n\t ]+/', ' ', $text);
$text = trim( $text );
if ( strpos( _x( 'words', 'Word count type. Do not translate!' ), 'characters' ) === 0 && preg_match( '/^utf\-?8$/i', get_option( 'blog_charset' ) ) ) {
$text = trim( preg_replace( "/[\n\r\t ]+/", ' ', $text ), ' ' );
preg_match_all( '/./u', $text, $words_array );
$words_array = array_slice( $words_array[0], 0, $num_words + 1 );
$sep = '';
} else {
$words_array = preg_split( "/[\n\r\t ]+/", $text, $num_words + 1, PREG_SPLIT_NO_EMPTY );
$sep = ' ';
}
if ( count( $words_array ) > $num_words ) {
array_pop( $words_array );
$text = implode( $sep, $words_array );
$text = $text . $more;
} else {
$text = implode( $sep, $words_array );
}
}
return $text;
}
```
Notice the line that is doing the stripping:
**Line:22** `$text = strip_tags($text, '<p>,<strong>');`
And your code should be like this:
```
$project_desc = get_field( 'project_description' );
if( !empty( $project_desc ) ):
$trimmed_text = wp_trim_excerpt_modified( $project_desc, 15 );
$last_space = strrpos( $trimmed_text, ' ' );
$modified_trimmed_text = substr( $trimmed_text, 0, $last_space );
echo $modified_trimmed_text . '...';
endif;

Since the action is 'wp\_head', that should get the `include_once("includes.php")` in the head area. I use `get_stylesheet_directory` because the includes.php file will be in a Child Theme.
Once that is loaded, then I can add some CSS with this:

I give the last two add\_actions a priority of '30' so they will be loaded after the includes.php file is loaded. (Because the includes.php has a priority of 20.)
But the includes.php file doesn't appear to be loading, as the 'some\_script' function (contained in includes.php) is not available, and causes an error.
So I need a way to add a `include_once('includes.php')` so that the functions inside there are available 'later' in the template. I don't think that `get_template_part` is appropriate because the `include_once` needs to be in the section.
**Added - But Why?**
Why do I need to do this? My template displays a form. The form's code and functions are in the include.php file. Even the form is displayed by a function in the include.php.
The include.php file is a 'package' of functions and scripts and actions and changing of DOM elements to perform specific functions when the form is displayed - and the user fills out the form and submits it. (The 'package' is the process that is used to protect forms - like contact forms - against spam-bots. It's an effective process, but a bit complex.

The include.php file is also built as a standalone/non-WP code that can be used on non-WP pages. I don't want to maintain two versions of the code.
The form has to 'live' in the visual look of whatever theme is being used, if used on a WP site. I figured a template would be the best way to do that. So I need to get my include.php 'inside' the template so that it's functions can be called.
As for the priorty used in the add\_action, that was an attempt to make sure that the include.php file is included in the area so that I can call the function that includes the CSS used for the form. If include.php is not loaded first, then the CSS-calling function will fail. | After much experimentation, and limited help from the googles, I figured how to do an '`include`' of an external functions file inside a Template.
The key is to use the `get_template_part` in your Template at the beginning (after the template header). The file specified in that function must be in your Theme's root folder, although I think it could also be in the theme's template folder.
```
get_template_part('my_custom_functions');
```
This will do the equivalent of a '`include`' in a non-WP PHP code. It will '`include`' the file called `my_custom_functions.php` .
Once you do that, then you can use filters to include things in the generated page's `<head>` area, or any other filters you need, as in:
```
add_filter('wp_head','some_function');
```
Which will call the `some_function()` function in your `my_custom_functions.php` file. (Make sure that your function names are unique, of course.)
This process, which is not easily found via the googles, will let you 'include' a file and then use functions in your include file in your WP Template. |

But now in this random category, I wish display a thumbnail from random post

Cat1 = Menus
Posts: Menu 1, menu 2...
Cat 2 = Dishes
Posts: Dish 1, Dish 2...
If my random cat is displaying Cat1, I need the thumbnail of Menu 1 or Menu 2
How can I do that ? | All you need to do is to add another query in your code:
```
function categorie_shortcode_callback() {
$html = '';
$categories = get_categories( array(

'taxonomy' => 'carte-category',

shuffle( $categories);
// you also don't need to loop through that array, since you only want to get first one
if ( ! empty($categories) ) {
$category = $categories[0];
$html.= '<h3> '. $category->name. '</h3>';
$html.= '<p class="txtContent"> '. $category->description. '</p>';

Thank you for any help :)
[](https://i.stack.imgur.com/mRLy9.jpg) | Well, in WP the word "loop" is mainly related to posts. It's easier to say that you want to display categories.
All you have to do is to get them using [`get_categories`](https://developer.wordpress.org/reference/functions/get_categories/) function and display them.
```
<?php
$categories = get_categories( array(
'orderby' => 'name',
'order' => 'ASC'
) );
if ( ! empty( $categories ) ) :
?>
<ul>
<?php foreach ( $categories as $category ) : ?>
<li><a href="<?php echo esc_attr(get_category_link( $category->term_id ) ); ?>"><?php echo esc_html( $category->name ); ?></a></li>
<?php endforeach; ?>
</ul>
<?php endif; ?>
```
And if you want to change the category title to some ACF custom field, then change this part:
```
<?php echo esc_html( $category->name ); ?>
```
to:
```
<?php echo wp_get_attachment_image( get_field('<FIELD_NAME>', $category), 'full' ); ?>
```
PS. Remember to change to real name of the field. It should return the ID of an image (and not the array - you should set it in field setting). You can also change the 'full' size to some other size. |

] | Any ideal way how to change Gutenberg's categories checkboxes to radio inputs? I have tried using this plugin: [Categories Metabox Enhanced](https://wordpress.org/plugins/categories-metabox-enhanced/).
But it doesn't work fully well with Gutenberg, meaning my conditions to show some field when a term is checked doesn't work. Also this plugin adds an extra meta box without replacing Gutenberg's default categories box.
[](https://i.stack.imgur.com/mbNZY.png) | Fortunately there is a hook that we can use to customize what component is used to render the taxonomy panels called `editor.PostTaxonomyType`.
Gutenberg renders taxonomy panels with a component called `PostTaxonomies`, which really just checks whether the taxonomy is heirarchical or not, and passes the props along to either the `HierarchicalTermSelector` or `FlatTermSelector` components accordingly. Normally, these two components don't appear to be exposed in the Gutenberg API, except for within the `editor.PostTaxonomyType` hook, which passes the relevant component as the 1st argument.
From there, all we have to do is extend the component, override the `renderTerms` method to change the input type from `checkbox` to `radio`, and override the `onChange` method to only return one selected term.
Unfortunately, extending the class within the hook seemed to cause a noticable performance hit, but storing the extended class in the `window` seemed to mitigate that.

// Return only the selected term ID
onChange( event ) {
const { onUpdateTerms, taxonomy } = this.props;
const termId = parseInt( event.target.value, 10 );
onUpdateTerms( [ termId ], taxonomy.rest_base );
}
// Copied from HierarchicalTermSelector, changed input type to radio
renderTerms( renderedTerms ) {
const { terms = [] } = this.props;

] | When I try to save my site in the Gutenberg Editor it just says "Updating failed".
How to fix that? | There are many reasons this error can occur. Those two were the most frequent for me:
Session-Cookie
--------------
Open the Javascript Console by pressing F12 and click on the tab "Console". If you see some error message that goes something like `cookie_nonce` it's a session cookie problem.
The problem solves by just completely logging out and possibly also deleting all cookies of your website.
File-Permissions
----------------
If you have a webserver you manage on your own it may be that file permissions are wrong.
The [instructions here](https://askubuntu.com/questions/46331/how-to-avoid-using-sudo-when-working-in-var-www) have never failed to resolve my issues so far, so it's worth checking out.
It's those commands:
Add yourself to www-data group:
```
sudo gpasswd -a "$USER" www-data
```
Change file permissions:
```
sudo chown -R "$USER":www-data /var/www
find /var/www -type f -exec chmod 0660 {} \;
sudo find /var/www -type d -exec chmod 2770 {} \;

How can I remove it from the pages? | There probably isn't a simple button you can push (unless there's a special one the theme developer created), but it can most likely be done via some basic theme tweaking.
First, make a child theme. There are lots of tutorials about how to do that.
Second, modify the child theme. Two options for this:
* hide the message via CSS: Find the CSS class for some enclosing HTML tag (there are several ways to determine that), and hide it via a CSS `display:none`. One drawback is that there's a risk Google might be unhappy with the page hiding things.
* customize the footer: Copy `footer.php` from the parent theme to the child theme. Edit the copy and remove the text you don't want, plus perhaps any enclosing now-empty HTML tags. One drawback is that if you later install an updated version of the parent theme, the child theme will still be using a modified version of the old footer.

325,724 | <p>With WP 5.0 you can now enable full width blocks in the editor by adding this to your theme:
<code>add_theme_support( 'align-wide' );</code></p>
<p>However, if you are using a custom theme you have to add <em>your own</em> CSS to make that work, as discussed in this <a href="https://github.com/WordPress/gutenberg/issues/8289" rel="nofollow noreferrer">Gutenberg issue</a>. There are lots of examples out there that do work, but there are scrollbar issues with all of them for anyone not on a Mac.</p>
<p>The problem is if you use <code>width: 100vw</code>, which is the best way I've found to do this, on Windows devices you get a horizontal scroll bar as soon as you have a vertical scroll bar on the page. I understand this is actually per the viewport width spec, so I'm really hoping to find another way to actually make this work on <strong>all</strong> devices.</p>
<p>What I have right now to enable full width is this CSS:</p>
<pre><code>.entry-content .alignfull {
position: relative;
width: 100vw;
left: 50%;
right: 50%;
margin-left: -50vw;
margin-right: -50vw;
}
body .entry-content .alignfull > * {
width: 100vw;
max-width: none;
}
</code></pre>
<p>I then add an <code>overflow: hidden;</code> on my outside container <code><div></code> of whatever wraps <code>the_content()</code> so as to hide the scrollbar. But what I'm looking for is a solution that doesn't rely on overflow hidden which can cause all kinds of unintended consequences. Any ideas out there?</p>

] | With WP 5.0 you can now enable full width blocks in the editor by adding this to your theme:
`add_theme_support( 'align-wide' );`
However, if you are using a custom theme you have to add *your own* CSS to make that work, as discussed in this [Gutenberg issue](https://github.com/WordPress/gutenberg/issues/8289). There are lots of examples out there that do work, but there are scrollbar issues with all of them for anyone not on a Mac.
The problem is if you use `width: 100vw`, which is the best way I've found to do this, on Windows devices you get a horizontal scroll bar as soon as you have a vertical scroll bar on the page. I understand this is actually per the viewport width spec, so I'm really hoping to find another way to actually make this work on **all** devices.
What I have right now to enable full width is this CSS:
```
.entry-content .alignfull {
position: relative;
width: 100vw;
left: 50%;
right: 50%;
margin-left: -50vw;
margin-right: -50vw;
}
body .entry-content .alignfull > * {
width: 100vw;
max-width: none;
}
```
I then add an `overflow: hidden;` on my outside container `<div>` of whatever wraps `the_content()` so as to hide the scrollbar. But what I'm looking for is a solution that doesn't rely on overflow hidden which can cause all kinds of unintended consequences. Any ideas out there? | After banging my head over that horizontal scroll bar issue, I think going the other way and adding a max width to blocks without the alignfull classes.

Nic | You can do this by editing the database via PhpMyAdmin.
Go to your database's **Options table** and find a row called **active\_plugins**.
You should see something like this...
```

i:8;s:24:"wordpress-seo/wp-seo.php";
i:9;s:34:"wpml-string-translation/plugin.php";
}
```
You can add a new row for your plugin. You will need to know the following.
* a:10 : 10 = the count of row (how many plugins are in the list)
* i:0;s:49 : i = the item position in the list
* i:0;s:49 : s = the character count
So you you can activate a new plugin by adding a new row and change the values like this...

] | Hi I used the Edin theme to build a wordpress website. I modified a big part of the CSS at the CSS editor, without having a clue what a child theme is. What should I do now? Create a child theme and delete the additional CSS of the parent theme? Any ideas?
Thank you very much!! | As [Jacob Peattie](https://wordpress.stackexchange.com/users/39152/jacob-peattie) mentioned, you've made custom CSS changes in a way that does not impact your theme. To expand a bit more, this is the *only* place you can make changes that will persist through a theme update or change. All other customizations get wiped.
So if you find you want to make further changes, you can create a child theme. You'll need access to the server/file system for this.
First create a new folder/directory in `wp-content/themes/`
You need to add two files to this directory: `style.css` and `functions.php`
In the `style.css` file add the following information:
```
/*
Theme Name: Edin Child
Template: edin
*/
```
Those are the only two required things in this file. Note that I have assumed that the "Template" is "edin"; make sure this is actually the parent theme directory name. [More info.](https://developer.wordpress.org/themes/advanced-topics/child-themes/#2-create-a-stylesheet-style-css)
Next is the `functions.php` file, which is a little more involved. Here is where tell your child theme to import information from its parent as well as importing its own style info.
```
<?php
add_action( 'wp_enqueue_scripts', 'my_theme_enqueue_styles' );
function my_theme_enqueue_styles() {
wp_enqueue_style( 'parent-style', get_template_directory_uri() . '/style.css' ); // get_template_directory_uri() returns the URI of the current parent theme, set in "Template" in your style.css
wp_enqueue_style( 'child-style',
get_stylesheet_directory_uri() . '/style.css',
array( $parent_style ),
wp_get_theme()->get('Version')
); // get_stylesheet_directory_uri() returns the child theme URI
}
?>
```
Then you'll have to zip your child theme directory up and upload it via the WP admin (or upload via ftp to `/wp-content/`, no zipping required), and finally activate the child theme. [More info.](https://developer.wordpress.org/themes/advanced-topics/child-themes/#3-enqueue-stylesheet)
You can find more about creating child themes directly from the [WordPress theme development docs.](https://developer.wordpress.org/themes/advanced-topics/child-themes/) |

I can see that the 4000+ comments are indeed in the database's `wp_comments` table, and I verified that the IDs of the associated posts are correct, but none of them show up in the WordPress admin area or the front-end. I haven't been able to find where the issue lies.
Maybe someone in the community has an idea for a possible fix? Thanks.
Edit: to clarify, I already moved the content to a new database, the issue happens on the new WordPress installation. The comments were imported to the database when importing the posts through the export/import tool. | edit: ok after working on this for the last hour ive finally found a solution that works without affecting uploading and without messing with ignore or reset
```
wp.media.frame.on('open', function() {
if (wp.media.frame.content.get() !== null) {
// this forces a refresh of the content
wp.media.frame.content.get().collection._requery(true);
// optional: reset selection
wp.media.frame.content.get().options.selection.reset();
}
}, this);

First, we need to enqueue our JS and include the wp.blocks package
```
// Add to functions.php
function gutenberg_enqueue() {
wp_enqueue_script(
'myguten-script',
// get_template_directory_uri() . '/js/gutenberg.js', // For Parent Themes
get_stylesheet_directory_uri() . '/js/gutenberg.js', // For Child Themes
array('wp-blocks') // Include wp.blocks Package
);
}
add_action('enqueue_block_editor_assets', 'gutenberg_enqueue');
```
---
Next, I found a couple solutions, the first is probably the best for your specific use-case.
**Method #1**
Use a filter function to override the default class. Well, in this case we are going to keep the "wp-block-image" class and just add the needed bootstrap class mt-2. But you could easily add whatever class you wanted. Add the code below and create a new image block, inspect it to see the figure tag now has the new class.
```
// Add to your JS file
function setBlockCustomClassName(className, blockName) {
return blockName === 'core/image' ?
'wp-block-image mt-2' :
className;
}
wp.hooks.addFilter(
'blocks.getBlockDefaultClassName',
'my-plugin/set-block-custom-class-name',
setBlockCustomClassName
);
```
---
**Method #2**
Add a setting in the block styles settings in the sidebar to add a class to the image.
```
// Add to your JS file
wp.blocks.registerBlockStyle('core/image', {
name: 'test-image-class',
label: 'Test Class'
});
```
[](https://i.stack.imgur.com/aIN1t.png)
This will add your class but unfortunately Gutenberg appends is-style- before the class, so it results in is-style-test-image-class. You would have to adjust your CSS accordingly.
---
**Method #3**
Manually adding the class via the Block > Advanced > Additional CSS Class option. Obviously, the class would need to be added for each image block.
[](https://i.stack.imgur.com/9DiVW.png)
---
**Note:** When adding or editing any of the JS above I needed to delete the block, refresh the page and then re-add the block to avoid getting a [block validation error](https://wordpress.org/gutenberg/handbook/designers-developers/developers/block-api/block-edit-save/#validation).

326,013 | <p>I'm loading some third party CSS with the help of wp_enqueue_style. I would like this CSS to be loaded in the footer, so it does not block rendering of the page. This would be fine, since this CSS is related to some chat functionality which is loaded on the page right away anyway. For JS, there is an option for adding right before the end of the body tag, instead of at the top of the page, but no such thing seem to exist for CSS. So, I'm wondering if there is some smart solution for this?</p>
<p>-- <strong>Edit</strong></p>
<p>I know that strictly speaking, style and link tags are not allowed anywhere but in the head, but I think it's a debatable question. Browsers do not complain about this and why would Google recommend this practice if it was so bad?</p>

A better technique would be to add the css-links to the dom with javaScript. You may even want to split out the css so that critical portions are loaded inline (so you avoid a [FOUC](https://en.wikipedia.org/wiki/Flash_of_unstyled_content))
Here's a technique as suggested by [GiftOfSpeed](https://www.giftofspeed.com/defer-loading-css/)
### This JS will create your css-link elements dynamically.
```
<script type="text/javascript">
/* First CSS File */
var wpse326013 = document.createElement('link');
wpse326013.rel = 'stylesheet';
wpse326013.href = '../css/yourcssfile.css';
wpse326013.type = 'text/css';
var godefer = document.getElementsByTagName('link')[0];
godefer.parentNode.insertBefore(wpse326013, godefer);
/* Second CSS File */
var wpse326013_2 = document.createElement('link');
wpse326013_2.rel = 'stylesheet';
wpse326013_2.href = '../css/yourcssfile2.css';
wpse326013_2.type = 'text/css';
var godefer2 = document.getElementsByTagName('link')[0];
godefer2.parentNode.insertBefore(wpse326013_2, godefer2);
</script>
```
### & for graceful degradation, we also include the following inside of the head element
```
<noscript>
<link rel="stylesheet" type="text/css" href="../css/yourcssfile.css" />
<link rel="stylesheet" type="text/css" href="../css/yourcssfile2.css" />
</noscript>
```
>
> You could also wrap the execution of the javaScript in a timeout, the following example would delay execution by 2 seconds.
>
>
>
```
setTimeout(function(){
var wpse326013 = document.createElement('link');
wpse326013.rel = 'stylesheet';
wpse326013.href = '../css/yourcssfile.css';
wpse326013.type = 'text/css';
var godefer = document.getElementsByTagName('link')[0];
godefer.parentNode.insertBefore(wpse326013, godefer);

326,066 | <p>I did a small adjustment in the 'custom css' in my theme settings, and now I broke my theme. Whenever I select a page as the home page, it says 'Nothing found'. Whenever I visit a page thats not a home page, it works perfectly fine. </p>
<p>Been looking for hours now. Any help appreciated. </p>
<p>Edit: The change in the CSS I made was temporary putting a piece of CSS within a comment (/* foo */) for testing purposes. </p>

] | I did a small adjustment in the 'custom css' in my theme settings, and now I broke my theme. Whenever I select a page as the home page, it says 'Nothing found'. Whenever I visit a page thats not a home page, it works perfectly fine.
Been looking for hours now. Any help appreciated.
Edit: The change in the CSS I made was temporary putting a piece of CSS within a comment (/\* foo \*/) for testing purposes. | Yes, technically you can. But you shouldn't load css in the footer, css links outside of the `<head>` are considered invalid.
A better technique would be to add the css-links to the dom with javaScript. You may even want to split out the css so that critical portions are loaded inline (so you avoid a [FOUC](https://en.wikipedia.org/wiki/Flash_of_unstyled_content))
Here's a technique as suggested by [GiftOfSpeed](https://www.giftofspeed.com/defer-loading-css/)
### This JS will create your css-link elements dynamically.
```
<script type="text/javascript">
/* First CSS File */
var wpse326013 = document.createElement('link');
wpse326013.rel = 'stylesheet';
wpse326013.href = '../css/yourcssfile.css';
wpse326013.type = 'text/css';
var godefer = document.getElementsByTagName('link')[0];
godefer.parentNode.insertBefore(wpse326013, godefer);
/* Second CSS File */
var wpse326013_2 = document.createElement('link');
wpse326013_2.rel = 'stylesheet';
wpse326013_2.href = '../css/yourcssfile2.css';
wpse326013_2.type = 'text/css';
var godefer2 = document.getElementsByTagName('link')[0];
godefer2.parentNode.insertBefore(wpse326013_2, godefer2);
</script>
```
### & for graceful degradation, we also include the following inside of the head element
```
<noscript>
<link rel="stylesheet" type="text/css" href="../css/yourcssfile.css" />
<link rel="stylesheet" type="text/css" href="../css/yourcssfile2.css" />
</noscript>
```
>
> You could also wrap the execution of the javaScript in a timeout, the following example would delay execution by 2 seconds.

```
setTimeout(function(){
var wpse326013 = document.createElement('link');

wpse326013.type = 'text/css';

<p>I'm trying to build a full width map in a wordpress site with leaflet.</p>
<p>My goal is to dsplay all post with markers on the map. When i click on the marker, a sidebar appear with the corresponding content in it. It's working.</p>
<p>But i have a problem that i can't solve. we can see it in the fiddle, when i move the map, i can see "the content" behind the map. so i have it in the sidebar and also on the page, behind the map.
In my wordpress site it's the same : my post contain a title, a video and a description. When i hover the map, in some place i can click on the video that is behind the map and it redirects me to youtube..
so it's a huge problem for me. Is it better to display content via data attributes, i tryed but without success. if i put the content in a data attribute, the map doen't appear in the page.
i don't understand why the post are duplicated..</p>

This way, you still have the current live site (\"production\") and have the staging area running in parallel - so you can make a side-by-side comparison.

This will still require you to switch back and forth, but as this plugin saves your files and database in one file, it is much easier to make and restore a back-up. Also, it provides a database search-and-replace option (which is a little more foolproof than the one I linked to earlier), in case you still decide on migrating any version to another domain/server or your localhost.</p>\n"

] | How can I show a post featured image by post id in gutenberg editor? I have a slider with latest posts and when I iterate through over posts I would like to show the post featured image as well. Here is my example snippet
```
const cards = displayPosts.map( ( post, i ) => {
console.log(post.featured_media)
return(<div className="card" key={i}>
<div className="card-image">
<div className="image is-4by3">
<PostFeaturedImage
currentPostId = {post.id}
featuredImageId = {post.featured_media}
/>
<div className="news__post-title">
<div className="title is-5">
<a href={ post.link } target="_blank">{ decodeEntities( post.title.rendered.trim() ) || __( '(Untitled)' ) }</a>
{ displayPostDate && post.date_gmt &&
<time dateTime={ format( 'c', post.date_gmt ) } className="wp-block-latest-posts__post-date">
{ dateI18n( dateFormat, post.date_gmt ) }
</time>
}

</div>
<div className="card-content">
<div className="content">
<p dangerouslySetInnerHTML={ { __html: post.excerpt.rendered } }></p>

```
const editor = wp.data.select('core/editor');

ImageObj gives you a reasonable amount of image data to work with. |

You needed to be more specific with your rule. Since there is a elementor class around those links I just used that class.

] | Basically what I'm asking is, is `wp_ajax_nopriv` exclusive to non-logged-in users?
Will a `wp_ajax_nopriv` action fire if a user is logged in? | Looking at [the WordPress source code](https://core.trac.wordpress.org/browser/tags/5.0.3/src/wp-admin/admin-ajax.php#L114), I'd say that `wp_ajax_nopriv_*` fires *only* if you're not logged in, and `wp_ajax_*` fires otherwise.
Here's the relevant bit, in `admin-ajax.php`, lines 85-115 in version 5.0.3:
```
if ( is_user_logged_in() ) {
// If no action is registered, return a Bad Request response.
if ( ! has_action( 'wp_ajax_' . $_REQUEST['action'] ) ) {
wp_die( '0', 400 );
}
/**
* Fires authenticated Ajax actions for logged-in users.
*
* The dynamic portion of the hook name, `$_REQUEST['action']`,
* refers to the name of the Ajax action callback being fired.
*
* @since 2.1.0
*/
do_action( 'wp_ajax_' . $_REQUEST['action'] );
} else {
// If no action is registered, return a Bad Request response.
if ( ! has_action( 'wp_ajax_nopriv_' . $_REQUEST['action'] ) ) {
wp_die( '0', 400 );
}
/**
* Fires non-authenticated Ajax actions for logged-out users.
*
* The dynamic portion of the hook name, `$_REQUEST['action']`,
* refers to the name of the Ajax action callback being fired.
*
* @since 2.8.0
*/
do_action( 'wp_ajax_nopriv_' . $_REQUEST['action'] );
}
```
So, if you're logged in (ie, `is_user_logged_in()` is `true`), it runs the `wp_ajax_*` action(s), otherwise it runs the `wp_ajax_nopriv_*` actions.
If you want the same action run regardless whether your user is logged in or not, I'd recommend you hook to **both** `wp_ajax_*` and `wp_ajax_nopriv_*`. |

We then loop through all the results in that array.

] | I have a custom post-type 'News' which has multiple custom taxonomies 'news-category', 'news-tags'. Each post contains between 4-8 'news-tags' and 1 'news-category'.
For my current post, I'd like to display related posts based on common 'news-tags' terms added to my current post, while also matching the 'news-category' term.
So, I'd like the related posts to look for posts of the same 'news-category' with the most number of 'news-tags' terms in common and display them in descending order.
If I were to display 4 related posts:

* the second post might have 3 'news-tags' terms in common,
* the third post might have 2 'news-tags' terms in common,
* and the last post might have 'news-tags' 1 term in common.
and they'd all belong to the same 'news-category'.
Would it be possible to do this? I've really been struggling with this so I'll appreciate any help. | Let's split the problem up in three bits: retrieving the related posts from the database, sorting them and displaying the result.
Post retrieval
--------------
This is possible using the [taxonomy parameters](https://codex.wordpress.org/Class_Reference/WP_Query#Taxonomy_Parameters) offered in `WP_Query`.
Let's first retrieve the category of the current post and find their IDs:
```
$categories = get_the_terms( get_the_ID(), 'news-category' );
foreach ( $categories as $category ) {
$category_ids[] = $category->term_id;
}
```
We do the same for the tags:
```
$tags = get_the_terms( get_the_ID(), 'news-tags' );
foreach ( $tags as $tag) {
$tag_ids[] = $tag->term_id;
}
```
Then, we build a set of query arguments (we later feed to a `WP_Query`-call):
```
$related_args = array(
'post_type' => array(
'news',
),
'post_status' => 'publish',
'posts_per_page' => -1, // Get all posts
'post__not_in' => array( get_the_ID() ), // Hide current post in list of related content
'tax_query' => array(
'relation' => 'AND', // Make sure to mach both category and term
array(
'taxonomy' => 'news-category',
'field' => 'term_id',
'terms' => $category_ids,
),
array(
'taxonomy' => 'news-tags',
'field' => 'term_id',
'terms' => $tag_ids,
),
),
);
```
Finally, we run the query that gives us an array of
```
$related_all = new WP_Query( $related_args );
```
Please note this query retrieves all posts that match the 'filter', as we're doing the ordering later on. If we'd now only query 4 posts, those might not be the most relevant.

If you want to stick with ordering on the overlap, I suggest you add a date filter in the query arguments, or limit the number of results to some finite value, from which set you then retrieve the most relevant posts.*
Post ordering
-------------
Following the previous step, `$related_all` is a `WP_Query`-object. We access the actual posts as follows, and store them in `$related_all_posts`:
```
$related_all_posts = $related_all->posts;
```
That gives us an array we can more easily work with. We then loop through all the results in that array. Per the comments in the code, when looping through the results, we find the tags associated to the (related) post, find their IDs, compare that with the `$tag_ids` (of the main post) found earlier and see how much overlap there is using [`array_intersect()`](https://secure.php.net/manual/en/function.array-intersect.php):
```
foreach($related_all_posts as $related_post){
// Find all tags of the related post under consideration
$related_post_tags = get_the_terms( $related_post->ID, 'news-tags' );
foreach ( $related_post_tags as $related_post_tag ) {
$related_tag_ids[] = $related_post_tag->term_id; // Save their IDs in a query
}
// Find overlap with tags of main post (in $tag_ids) using array_intersect, and save that number in
// an array that has the ID of the related post as array key.
$related_posts_commonality[$related_post->ID] = count(array_intersect($related_tag_ids, $tag_ids));
}
```
We then sort that latest array by value, from high to low, using [`arsort()`](https://secure.php.net/manual/en/function.arsort.php).
```
arsort($related_posts_commonality);
```
Finally, we limit it to only four posts using [`array_slice()`](https://secure.php.net/manual/en/function.array-slice.php):
```
$related_posts_commonality = array_slice($related_posts_commonality, 0, 4);
```
You can find the IDs of the related posts using [`array_keys`](https://secure.php.net/manual/en/function.array-keys.php), e.g.:
```
$related_posts_IDs = array_keys($related_posts_commonality);
```
Post display
------------
To actually display the posts, there's two routes you can take. You can either use the `$related_posts_commonality` array to loop through the results of `WP_Query` (i.e., `$related_all`), save the matching posts (in their right order) in a new array or object and loop through these once again for display. As this doesn't require additional queries, it's probably the most efficient one. However, it's also a pain.
As such, you can also use simply use the IDs we've just found (`$related_posts_IDs`) to run another query.
```
$related_sorted = WP_query(array('post__in' => $related_posts_IDs));
```
Then, you can use a regular [loop](https://codex.wordpress.org/Class_Reference/WP_Query#Usage) (`while ($related_sorted->have_posts())` and so on) to go through and display the results using functions as `the_title()` and `the_content()`. |

] | I am trying to write a `.htaccess` rule to redirect the URL to a subdomain.
Example: `example.com/pagecategory/page-single` → `pagecategory.example.com/page-single`
I've added wildcard subdomain on my hosting.
Can anyone help me write the `.htaccess` code? | Let's split the problem up in three bits: retrieving the related posts from the database, sorting them and displaying the result.
Post retrieval
--------------
This is possible using the [taxonomy parameters](https://codex.wordpress.org/Class_Reference/WP_Query#Taxonomy_Parameters) offered in `WP_Query`.
Let's first retrieve the category of the current post and find their IDs:
```
$categories = get_the_terms( get_the_ID(), 'news-category' );
foreach ( $categories as $category ) {
$category_ids[] = $category->term_id;
}
```
We do the same for the tags:
```
$tags = get_the_terms( get_the_ID(), 'news-tags' );
foreach ( $tags as $tag) {
$tag_ids[] = $tag->term_id;
}
```
Then, we build a set of query arguments (we later feed to a `WP_Query`-call):
```
$related_args = array(
'post_type' => array(
'news',
),
'post_status' => 'publish',
'posts_per_page' => -1, // Get all posts
'post__not_in' => array( get_the_ID() ), // Hide current post in list of related content
'tax_query' => array(
'relation' => 'AND', // Make sure to mach both category and term
array(
'taxonomy' => 'news-category',
'field' => 'term_id',
'terms' => $category_ids,
),
array(
'taxonomy' => 'news-tags',
'field' => 'term_id',
'terms' => $tag_ids,
),
),
);
```
Finally, we run the query that gives us an array of
```
$related_all = new WP_Query( $related_args );
```
Please note this query retrieves all posts that match the 'filter', as we're doing the ordering later on. If we'd now only query 4 posts, those might not be the most relevant.
*Sidenote: the above query is quite heavy, in the sense that it (potentially) retrieves a large number of posts. When I've created a related posts section for a client project (also a news section), I ordered by date rather than relevance. That allows you to set a limit to the number of posts you retrieve from the database (change the `-1` to `4` in your case, and add `'orderby' => array( 'date' => 'DESC' )` to the `$related_args`-array). If you want to stick with ordering on the overlap, I suggest you add a date filter in the query arguments, or limit the number of results to some finite value, from which set you then retrieve the most relevant posts.*
Post ordering
-------------
Following the previous step, `$related_all` is a `WP_Query`-object. We access the actual posts as follows, and store them in `$related_all_posts`:
```
$related_all_posts = $related_all->posts;
```
That gives us an array we can more easily work with. We then loop through all the results in that array. Per the comments in the code, when looping through the results, we find the tags associated to the (related) post, find their IDs, compare that with the `$tag_ids` (of the main post) found earlier and see how much overlap there is using [`array_intersect()`](https://secure.php.net/manual/en/function.array-intersect.php):
```
foreach($related_all_posts as $related_post){
// Find all tags of the related post under consideration
$related_post_tags = get_the_terms( $related_post->ID, 'news-tags' );
foreach ( $related_post_tags as $related_post_tag ) {
$related_tag_ids[] = $related_post_tag->term_id; // Save their IDs in a query
}
// Find overlap with tags of main post (in $tag_ids) using array_intersect, and save that number in
// an array that has the ID of the related post as array key.
$related_posts_commonality[$related_post->ID] = count(array_intersect($related_tag_ids, $tag_ids));
}
```
We then sort that latest array by value, from high to low, using [`arsort()`](https://secure.php.net/manual/en/function.arsort.php).
```
arsort($related_posts_commonality);
```
Finally, we limit it to only four posts using [`array_slice()`](https://secure.php.net/manual/en/function.array-slice.php):
```
$related_posts_commonality = array_slice($related_posts_commonality, 0, 4);
```
You can find the IDs of the related posts using [`array_keys`](https://secure.php.net/manual/en/function.array-keys.php), e.g.:
```
$related_posts_IDs = array_keys($related_posts_commonality);
```
Post display
------------
To actually display the posts, there's two routes you can take. You can either use the `$related_posts_commonality` array to loop through the results of `WP_Query` (i.e., `$related_all`), save the matching posts (in their right order) in a new array or object and loop through these once again for display. As this doesn't require additional queries, it's probably the most efficient one. However, it's also a pain.
As such, you can also use simply use the IDs we've just found (`$related_posts_IDs`) to run another query.
```
$related_sorted = WP_query(array('post__in' => $related_posts_IDs));
```
Then, you can use a regular [loop](https://codex.wordpress.org/Class_Reference/WP_Query#Usage) (`while ($related_sorted->have_posts())` and so on) to go through and display the results using functions as `the_title()` and `the_content()`. |

] | I need to disable the Gutenberg text-settings tab in all Blocks. Is this possible with a funtion in funtions.php?
I could disable the colors tab, but found no solution for the text-settings:
```
function disable_tabs() {
add_theme_support( 'editor-color-palette' );
add_theme_support( 'disable-custom-colors' );
}
add_action( 'after_setup_theme', 'disable_tabs' );
```
[](https://i.stack.imgur.com/QlcmX.jpg) | The closest I can find in [the documentation](https://wordpress.org/gutenberg/handbook/designers-developers/developers/themes/theme-support/) is disabling custom font size (the text input) and forcing the dropdown font size to only contain "Normal".
```
add_action('after_setup_theme', 'wpse_remove_custom_colors');
function wpse_remove_custom_colors() {
// removes the text box where users can enter custom pixel sizes
add_theme_support('disable-custom-font-sizes');
// forces the dropdown for font sizes to only contain "normal"
add_theme_support('editor-font-sizes', array(
array(
'name' => 'Normal',
'size' => 16,
'slug' => 'normal'
)
) );
}
```
Note this may not work for non-Core blocks - they may have their own way of registering font size etc. that isn't affected by theme\_support. Hoping someone else from the community knows how to disable the drop caps as well.
**Update: a way to remove Drop Caps**
This wouldn't be my preferred method, because you can still add a Drop Cap in the editor and it just doesn't render in the front end, but it's all I have been able to achieve so far:
There is a `render_block()` hook where you can change what renders on the front end without changing what shows in the editor or gets saved to the database.
```
add_filter('render_block', function($block_content, $block) {
// only affect the Core Paragraph block
if('core/paragraph' === $block['blockName']) {
// remove the class that creates the drop cap
$block_content = str_replace('class="has-drop-cap"', '', $block_content);
}
// always return the content, whether we changed it or not
return $block_content;
}, 10, 2);
```
This method changes the outer appearance rather than the actual content, so that if you ever wanted to allow drop caps, you could just remove the filter and all the ones that people had added in the editor would suddenly appear. |
