] | I have, based on post category, added a password form (shortcode) whereof the purpose is to hide certain HTML code.
To do this, I have wrapped certain HTML-tags in a shortcode using the `the_content` filter.
The password itself is added through an array, which would be much better suited as an global setting through the WP admin settings page - but that's a different story.
**My main problem is this;** after submitting the password - no matter if the password is right or wrong - the user get "scrolled" all the way to the top of the page.
That should not happen, which is why I added a ID to the form. Upon submitting the correct password, the user should be kept in the same place, which is where the form was which is where the HTML code now is.
Makes sense? Part of the problem is this; there's no message for "password successful" or "incorrect password".
As you can see in the code, I've already tried to add the ID to the path using this:
`path=/#functioncode` without success.
**This is the full code:**
```
add_shortcode( 'protected', 'protected_html' );
function protected_html( $atts, $content=null ) {
$functionUserPassword = isset( $_REQUEST['password']) ? $_REQUEST['password'] : ( isset( $_COOKIE['functionUserPassword']) ? $_COOKIE['functionUserPassword'] : NULL );
if ( in_array( $functionUserPassword, array('password') ) ) {
$return_html_content = do_shortcode($content);
} else {
$return_html_content =
'<div id="functioncode" style="margin-top:20px;font-size:15px;">To view the content of this section, submit your password.</div>
<form method="post" onsubmit="functionCookie(this); return false;">
<input required style="display: block; width: 69%; height: 50px; margin-right: 1%; float: left; border: 2px solid #333;" type="text" placeholder=" Password Here" name="password" id="functionUserPassword">
<input style="display: block; margin: 0px; width: 30%; height: 50px; background-color: #333; color: #fff;" type="submit" value="Submit">
</form>
<script>
function functionCookie(form){
document.cookie = "functionUserPassword=" + escape(form.functionUserPassword.value) + "; path=/#functioncode";
</script>';
}
return $return_html_content;
}
```
**Here's the code which I am using with the content filter:**
```
add_filter( 'the_content', 'wrap_html_in_shortcode', 9 );
function wrap_html_in_shortcode( $content ) {
if ( ! in_category( 'premium' ) ) return $content;
$content = preg_replace('/(<span[^>]*>\s*<div[^>]*>)/',"[protected]$1", $content);
$content = preg_replace('/(<\/div>\s*<\/span>)/', "$1[/protected]", $content);
return $content;
}
``` | Not exactly sure what you are trying to do and this doesn't look like a WordPress issue, but submitting a html form will certainly lead to a new page load. So what you want is redirect not to the same page (which happens when you specify no action, leading the page to scroll to the top) but to an anchor on that page. The [usual way to do this](https://stackoverflow.com/questions/8395269/what-do-form-action-and-form-method-post-action-do) is to include it in the `action` variable of your `form` like this:
```

<form method="POST" action="#somewhere">
...
</form>

383,498 | <p>I have a site that uses a set of 3 images for the header of its subpages. Each page has a different set of images. From what I could find, my best way to accomplish this would be to place an if statement within my <code>header-subpage.php</code>. The following is a snippet of my code.</p>
<pre><code><?php
if ( is_page( 'available-homes' ) ) {
get_template_part( 'sections/banner-images', 'available-homes' );
} elseif ( is_page( 'design-services' ) ) {
get_template_part( 'sections/banner-images', 'design-services' );
} elseif ( is_page( 'about-us' ) ) {
get_template_part( 'sections/banner-images', 'about-us' );
} ........
} elseif ( is_page( 'portfolio' ) ) {
get_template_part( 'sections/banner-images', 'portfolio' );
} elseif ( is_page( 'galleries' ) ) {
get_template_part( 'sections/banner-images', 'galleries' );
} else {
echo "page images undefined...";
}
</code></pre>
<p>Is there a more efficient way for me to do this? I am still learning PHP, but it seems like there might be a better more efficient way to loop through the pages than what I have done.</p>
<p>Thank you for any suggestions.</p>

Is there a way to select only heading blocks with parse\_blocks or some other clever way? | [`parse_blocks()`](https://developer.wordpress.org/reference/functions/parse_blocks/) simply returns all blocks found in the post content, so for what you're trying to get, you could use a function which calls itself recursively like so:
```php
function my_find_heading_blocks( $blocks ) {
$list = array();
foreach ( $blocks as $block ) {
if ( 'core/heading' === $block['blockName'] ) {
// add current item, if it's a heading block
$list[] = $block;
} elseif ( ! empty( $block['innerBlocks'] ) ) {
// or call the function recursively, to find heading blocks in inner blocks
$list = array_merge( $list, my_find_heading_blocks( $block['innerBlocks'] ) );
}
}
return $list;
}
// Sample usage:
$post = get_post();
$blocks = parse_blocks( $post->post_content );
$headings = my_find_heading_blocks( $blocks );

383,658 | <p>I am trying to understand some fundamentals of php with regards to adding new functions to actions. I found a tutorial where he adds a new function to the <code>save_post</code> action…</p>

<p>Is my understanding correct that when we fire the action elsewhere via <code>do_action('save_post', $post_ID, $post, $update)</code> the parameters we pass it at this time are automatically & instantly available to use in our new function we are adding to the action and that is what is going on here?</p>
<p>When we write <code>add_action('save_post', ‘log_when_saved’);</code> we are adding some new function to be run when the action is fired.

"text": "<p>Everything Butterend_Toast says is correct, but I want to touch on <em>why</em> it works that way.</p>\n<p>Under the hood, <code>do_action()</code> and <code>apply_filters()</code> are just calling the core PHP function <a href=\"https://www.php.net/manual/en/function.call-user-func-array.php\" rel=\"nofollow noreferrer\"><code>call_user_func_array()</code></a>. When you run <code>add_action()</code> you are storing a reference to a <a href=\"https://www.php.net/manual/en/language.types.callable.php\" rel=\"nofollow noreferrer\">callable</a>, with a number representing how many arguments that function accepts.</p>\n<pre><code>add_action(\n 'save_post', // Hook name\n 'log_when_saved', // Callable.\n 10, // Priority\n 3 // How many arguments the callable can accept.\n);\n</code></pre>\n<p>So when you call <code>do_action()</code>, WordPress uses <code>call_user_func_array()</code> with that callable, along with an array of whichever arguments were passed to <code>do_action()</code>.</p>\n<p>To avoid certain errors, and to allow developers to use functions that accept fewer arguments than were passed to <code>do_action()</code>, WordPress will truncate the array passed to <code>call_user_func_array()</code> to match he number of accepted arguments given in the <code>add_action()</code> call. If it didn't do this then you would get a fatal error if your function didn't accept all the variables.</p>\n<p>So, the variables that you can use in your callback function are determined by:</p>\n<ol>\n<li>Which arguments were passed to <code>do_action()</code>.</li>\n<li>How many variables you chose to accept when running <code>add_action()</code>.</li>\n</ol>\n<p>The name of the variables does not matter, but the order <em>does</em>. This is how all PHP functions work. If I write this function:</p>\n<pre><code>function add_numbers( $one, $two ) {\n return $one + $two;\n}\n</code></pre>\n<p>The first argument passed to the function will be given the variable name <code>$one</code> inside that function, and the second will be given the name <code>$two</code>. The variable names used outside the function don't matter:</p>\n<pre><code>$a = 1;\n$b = 3;\n$c = add_numbers( $a, $b ); // Works fine.\n$d = add_numbers( 2, 4 ); // Even if I don't pass named variables.\n</code></pre>\n<p>The same is true for hooks. The parameters passed to <code>do_action()</code> are passed as arguments to <code>call_user_func_array()</code> <em>in order</em>. So if I hook like this:</p>\n<pre><code>add_action( 'save_post', 'log_when_saved', 10, 3 );\n</code></pre>\n<p>Then this works:</p>\n<pre><code>function log_when_saved( $post_id, $post, $update ) {\n echo $post_id;\n}\n</code></pre>\n<p>And so does this:</p>\n<pre><code>function log_when_saved( $a $b, $c ) {\n echo $a;\n}\n</code></pre>\n<p>But regardless of the name, <code>$a</code> will always be the post ID passed to <code>do_action()</code> because it's the first argument. So in this example, <code>$b</code> is the post ID:</p>\n<pre><code>function log_when_saved( $b, $a, $c ) {\n echo $b;\n}\n</code></pre>\n<p>That's why it's a good practice to match the variable names to what was being passed. Not for any technical reason, but to make it easier to understand.</p>\n<p>This will <em>not</em> work:</p>\n<pre><code>function log_when_saved( $a, $b, $c ) {\n echo $post_id;\n}\n</code></pre>\n<p>Because <code>$post_id</code> is undefined. If you want to use the ID of the post being saved, you need to use the one passed as the first argument.</p>\n<hr />\n<p>This all raises the question of how to know which variables you can or need to accept in your hook callbacks. That's where the <strong>documentation</strong> comes in. If you look at <a href=\"https://developer.wordpress.org/reference/hooks/save_post/\" rel=\"nofollow noreferrer\">the documentation for <code>save_post</code></a> you will see which arguments are passed to callback functions, so you know which argument represents which kind of value.</p>\n"

```

Is my understanding correct that when we fire the action elsewhere via `do_action('save_post', $post_ID, $post, $update)` the parameters we pass it at this time are automatically & instantly available to use in our new function we are adding to the action and that is what is going on here?
When we write `add_action('save_post', ‘log_when_saved’);` we are adding some new function to be run when the action is fired. This new function to be run can automatically use the variable values that were defined when we fired the action via the `do_action`. Is this correct?

and it would know that `$some_random_variable_name` would be the post id because is first defined argument in our `do_action(‘save_post’, $post_ID, $post, $update)` statement?
Thank you in advance, | For this example lets say we have the following
```
do_action('bt_custom_action', get_the_ID(), get_the_title(), get_the_content());
```
The arguments that will be passed to `add_action` would be in this order
1. the post id
2. the post title
3. the post content
By default if we hook into our `do_action` without any arguments, like this
```
add_action('bt_custom_action', 'bt_callback_func');
```
Our call back function "gets" one argument, in this case the ID
```
function bt_callback_func ($id) {
echo $id;
}
```
In order to get the post content we would need to do something like this
```
add_action('bt_custom_action', 'bt_callback_func', 10, 3);
```
This will pass three arguments to our callback function and to use them we would do something like this
```
function bt_callback_func ($id, $title, $content) {
echo $id . '<br>' . $title . '<br>' . $content;
}
```
Now to finally answer your question about getting a specific argument.
If we go by this example
```
add_action('bt_custom_action', 'bt_callback_func', 10, 3);
```
we know that our callback function will get three arguments, but we only need the content. We don't have to set parameters for each and every expected argument. We can use PHPs `...`, see [Variable-length argument lists](https://www.php.net/manual/en/functions.arguments.php#functions.variable-arg-list).
So now our callback function will look like this
```
function bt_callback_func (...$args) {
echo args[2];
}
```
Because in our add action we told that our callback will expect three arguments and we know that the third argument is what we need (the content), using `...` we now created a variable that will contain all passed argumnets.
In this case it will contain an array with three elements in order. ID, title and then content.
We know that content is last, third, in our array. We can target it directly like this `$args[2]`.

I dont know what post type you want to get but try adding it to the $args as well.
So you initial $args will look like this
```
$args = array(
'post_type' => 'post',
// 'post_status' => 'publish', // this is optional, this will get only published posts
'orderby' => 'date',
'posts_per_page' => -1

"text": "<p>I'm answering this to provide more background information, but @Sally answer is the more direct answer here since it's too long for a comment.</p>\n<p>Although I don't consider myself nearly as talented as many WP Core contributors, I've been actively involved with the WordPress project and beyond for over a decade -- during that time, I can confidently say that the issue of transients in WordPress has probably been one of the more confusing subjects (for everyone), and a headache that has reappeared several times over the years.</p>\n<p>The idea of "garbage collecting" transients <a href=\"https://core.trac.wordpress.org/ticket/20316\" rel=\"nofollow noreferrer\">was brought up</a> over 10 years years ago on Trac. Despite this, <a href=\"https://www.google.com/search?q=site:https://core.trac.wordpress.org/%20transients\" rel=\"nofollow noreferrer\">dozens of similar</a> and tangential tickets have been raised since then... one of the biggest problems was that for several years, WP Cron didn't actually call the function to delete expired transients! Around 5 years ago, this was addressed in a <a href=\"https://core.trac.wordpress.org/ticket/41699\" rel=\"nofollow noreferrer\">new ticket</a> and a job <a href=\"https://core.trac.wordpress.org/changeset/42008\" rel=\"nofollow noreferrer\">was added</a> to WP Core cron tasks...</p>\n<p>Despite all this, the truth remains muddy. Why? Because so many theme and plugin developers don't understand the proper use of transients, it means that tons of transients in the average WordPress database either don't have expiration dates, should be "options" instead of "transients", and many other things that involve failure to communicate and/or implement best practices.</p>\n<p>Plus, there's object caching, which has become increasingly common in recent years. <strong>If you install an object cache like Memcached or Redis on your server, these key/value entities will no longer be stored as "transients" in your MySQL database, but will instead exist in the object cache space, where they might disappear at any given time because of a server reboot or otherwise.</strong></p>\n<p>So what's the best solution? IMO plan for all kinds of user error, and proceed as follows:</p>\n<ol>\n<li>Delete all transients from your database</li>\n<li>Install and activate object caching</li>\n<li>Rely on WP Core to run delete_expired_transients daily</li>\n</ol>\n<p>My agency LittleBizzy was one of several other plugin developers with a "Deleted Expired Transients" function; many still exist to this day. Keep in mind that using these plugins WILL NOT properly delete many transients from your database because of issues mentioned above. For this reason, and to ensure a cleaner database, I think it makes more sense to occasionally delete ALL transients and/or purge your object cache.</p>\n<p>This is exactly the approach that our free <a href=\"https://github.com/littlebizzy/slickstack/blob/master/bash/ss-purge-redis.txt\" rel=\"nofollow noreferrer\">SlickStack</a> script now takes.</p>\n<p>Remember, anything in transients (or object caching) should always be considered temporary non-critical data, so it should always be safe to delete it when needed -- otherwise your code is <strong>doing_it_wrong</strong>.</p>\n"

] | I have a single page site with all content on it. The only other page I have is a "thanks for submitting the contact form" page. In this "thankssubmit.php" page I have my PHP form submission code.
I'm new to wordpress so I may be doing this totally wrong but I've created a custom page template for this "thankssubmit.php" page using /*Template Name: Thanks Submit*/.
I've then applied that template to a brand new page in WP. I can't add .php to the slug which is maybe the only problem but I can't see a way around this. A strange issue is that when I submit the form I go to the correct URL but get a "page not found" error. If I copy and paste this exact same URL I go to the correct page...
Below is the code for all.
I've had a look and I can't see this question being a repeat but if so a nudge in the right direction would be greatly appreciated!
Form

This is probably a workaround for a supposed [bug in Apache](https://www.jeffgeerling.com/blog/2017/stripping-vary-host-header-apache-response-using-varnish) ([#58231](https://bz.apache.org/bugzilla/show_bug.cgi?id=58231))**\*1** that could prevent certain caching proxies from caching the response when the `Vary: Host` HTTP response header is set. Apache might be setting this automatically when querying the `HTTP_HOST` server variable in a mod\_rewrite `RewriteCond` directive (or Apache Expression).
**\*1** Although this is arguably a bug in the cache, not Apache. The Apache behaviour is "by design" and a `Vary: Host` header should not prevent a cache from working since this is really the default behaviour.
However, if you are *varying* the HTTP response based on other elements of the request (such as the `Accept`, `Accept-Language` or `User-Agent` HTTP request headers) then the `Vary` HTTP response header should be set appropriately and should not simply be *unset*.
I am surprised, however, that this directive would cause an error. It implies that mod\_headers is not installed - which is "unlikely". However, you can protect against this and surround the directive in an `<IfModule>` directive. For example:
```
# SGO Unset Vary
<IfModule mod_headers.c>
Header unset Vary
</IfModule>
# SGO Unset Vary END
```
(From the indentation of the directive in your question it almost looks like this `<IfModule>` wrapper was missing?)
Now, the `Header` directive will be processed only if mod\_headers is installed. |

You would place the above rule second, between your existing rules. And modify your 1st rule that removes the trailing slash to also reduce multiple slashes, thus preventing an unnecessary additional redirect should a request contain both multiple slashes and a trailing slash. For example:
```
# Remove trailing slash from non-directory URLs AND reduce multiple slashes
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule (.+)/$ https://example.com/$1 [R=301,L]
# Reduce multiple slashes to single slashes
RewriteCond %{THE_REQUEST} \s[^?]*//
RewriteRule (.*) https://example.com/$1 [R=301,L]
# Force HTTPS and remove WWW
RewriteCond %{HTTP_HOST} ^www\. [OR,NC]
RewriteCond %{https} off
RewriteRule (.*) https://example.com/$1 [R=301,L]
```
I just tidied the regex in the `RewriteCond` directive that checks against the `HTTP_HOST` server variable. `^www\.(.*)$` can be simplifed to `^www\.` since you are not making use of the backreference here.
You do not need the `<IfModule>` wrapper.
Clear your browser cache before testing and preferably test first with 302 (temporary) redirects to avoid potential caching issues.

These rules certainly need to go near the beginning of the `.htaccess` file, *before* the WordPress front-controller.
However, they must go *before* the `# BEGIN WordPress` section. Not inside this block, otherwise they will be overwritten since WP itself maintains this code block.

This uses the fact that the URL-path matched by the `RewriteRule` *pattern* has already had multiple slashes reduced. The preceding *condition* checks that there were multiple slashes somewhere in the URL-path in the initial request.
You would place the above rule second, between your existing rules. And modify your 1st rule that removes the trailing slash to also reduce multiple slashes, thus preventing an unnecessary additional redirect should a request contain both multiple slashes and a trailing slash. For example:
```
# Remove trailing slash from non-directory URLs AND reduce multiple slashes
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule (.+)/$ https://example.com/$1 [R=301,L]
# Reduce multiple slashes to single slashes
RewriteCond %{THE_REQUEST} \s[^?]*//
RewriteRule (.*) https://example.com/$1 [R=301,L]
# Force HTTPS and remove WWW
RewriteCond %{HTTP_HOST} ^www\. [OR,NC]
RewriteCond %{https} off
RewriteRule (.*) https://example.com/$1 [R=301,L]
```
I just tidied the regex in the `RewriteCond` directive that checks against the `HTTP_HOST` server variable. `^www\.(.*)$` can be simplifed to `^www\.` since you are not making use of the backreference here.
You do not need the `<IfModule>` wrapper.
Clear your browser cache before testing and preferably test first with 302 (temporary) redirects to avoid potential caching issues.

These rules certainly need to go near the beginning of the `.htaccess` file, *before* the WordPress front-controller.
However, they must go *before* the `# BEGIN WordPress` section. Not inside this block, otherwise they will be overwritten since WP itself maintains this code block.
They should not be overwritten if placed *before* the `# BEGIN WordPress` comment marker. |

Any help on how to make this work? | As @cjbj noted in a comment, this is probably a timing issue. This means that instead of directly adding the code to `functions.php` you need to wrap it inside a callback function and attach it to a later firing action. WordPress, themes and plugins too, [loads](https://wordpress.stackexchange.com/questions/71406/is-there-a-flowchart-for-wordpress-loading-sequence) and [does](https://codex.wordpress.org/Plugin_API/Action_Reference) things in certain order. Thus some code needs to be added with actions to make them properly.
Personally, I usually add `body_class` filtering, if it depends on some data, on [`template_redirect`](https://developer.wordpress.org/reference/hooks/template_redirect/) (*Fires before determining which template to load*) action to make sure the code will have all the data it needs to determine how to filter the classes.
```
// Hook anonymous callback to template_redirect action
add_action(
'template_redirect',
function(){
// Get data
$cart_items = wcs_cart_contains_renewal();
// Check for truthy condition
if ( $cart_items ) {
// Hook anonymous callback to body_class filter
add_filter(
'body_class',
function( $classes ) {
// Add additional class
$classes[] = 'renewal-order';
return $classes;
}
);
}
}
);
```
*You can use named callback instead of anonymous ones, if you wish.* |
384,453 | <p>I understand my question may be a bit broad, or even easy to answer. I have been building custom blocks using the <code>--es5</code> flag of <code>@wordpress/create-block</code> (<a href="https://developer.wordpress.org/block-editor/packages/packages-create-block/" rel="nofollow noreferrer">https://developer.wordpress.org/block-editor/packages/packages-create-block/</a>), which has been fairly successful on projects.</p>
<p>The reason for using this method is that during development and post-launch there are often many changes required of the block and from my past experience (over a year ago) the ES Next method effectively 'killed' the block as soon as a change was made. So you would have to go through every instance of this block and change it.</p>
<p>Have WP's developers come up with a workable solution for this which enables developers to use the ES Next method in a project safely? I'd prefer to be using the methods as intended. The documentation since it's release has not been great so I thought it would be better to ask the wider community.</p>
<p>To try and explain better what I mean:</p>
<p>Building a custom block using the following method (<a href="https://github.com/WordPress/gutenberg-examples/blob/master/03-editable/block.js" rel="nofollow noreferrer">https://github.com/WordPress/gutenberg-examples/blob/master/03-editable/block.js</a>) of attributes with the --es5 flag appears to be more stable in terms of backwards compatibility. If I were to make changes to the render template (<a href="https://github.com/WordPress/gutenberg-examples/blob/master/03-editable/index.php" rel="nofollow noreferrer">https://github.com/WordPress/gutenberg-examples/blob/master/03-editable/index.php</a>) it wouldn't break the block.</p>
<p>Using the 'React' method (<a href="https://github.com/WordPress/gutenberg-examples/blob/master/03-editable-esnext/src/index.js" rel="nofollow noreferrer">https://github.com/WordPress/gutenberg-examples/blob/master/03-editable-esnext/src/index.js</a>), in my past experience, has caused issues. If I build a custom block using this method and a change has been made to the block's code, it 'kills' the block. There is no backwards compatibility from what I can tell.</p>
<p>I'm wondering if this is just something that has actually been resolved since the block editor was first introduced. Or is the way to continue building custom blocks is using the ES5 method</p>
<p><strong>One important bit I have missed out</strong>
What I was originally alluding to is that I am using server side rendered blocks (excuse my terminology here, its not exactly a clear subject to those unfamiliar with it) that gets around the 'change anything in the block code and you have to add that block again in the editor' problem. Not Ideal for client handover.</p>
<pre><code>register_block_type( 'create-block/perk', array(
'editor_script' => 'create-block-perk-block-editor',
'editor_style' => 'create-block-perk-block-editor',
'style' => 'create-block-perk-block',
'render_callback' => 'perk_block_render',
) );
function perk_block_render($attr, $content) {
$str = '';
if(isset($attr['mediaID'])) {
$mediaID = $attr['mediaID'];
$src = wp_get_attachment_image_src($mediaID, 'perk');
if($src && is_array($src) && isset($src[0])) {
$srcset = wp_get_attachment_image_srcset($mediaID);
$sizes = wp_get_attachment_image_sizes($mediaID, 'perk');
$alt = get_post_meta($mediaID, '_wp_attachment_image_alt', true);
if(!$alt) {
$alt = 'Perk icon';
}
}
}
if(isset($attr['titleContent'])) {
$title = $attr['titleContent'];
}
if(isset($attr['subContent'])) {
$subtitle = $attr['subContent'];
}
$str = "<div class='perks__item animate'>";
if($mediaID) {
$str .= "<img loading='lazy' width='170' height='170' src='{$src[0]}' alt='{$alt}'/>";
}
if($title) {
$str .= "<h2>{$title}</h2>";
}
if($subtitle) {
$str .= "<p>{$subtitle}</p>";
}
$str .= "</div>";
return $str;
</code></pre>
<p>}</p>
<p>I see now that it is not ES5/ESNext related, however, after looking through recent videos it seems like it is still an issue with developing custom blocks using WordPress's 'preferred' method. And also, judging by the answers using server-side-rendered blocks is the only way away this. Is my code going to experience issues if I continue to use server-side rendered blocks?</p>

] | I understand my question may be a bit broad, or even easy to answer. I have been building custom blocks using the `--es5` flag of `@wordpress/create-block` (<https://developer.wordpress.org/block-editor/packages/packages-create-block/>), which has been fairly successful on projects.
The reason for using this method is that during development and post-launch there are often many changes required of the block and from my past experience (over a year ago) the ES Next method effectively 'killed' the block as soon as a change was made. So you would have to go through every instance of this block and change it.
Have WP's developers come up with a workable solution for this which enables developers to use the ES Next method in a project safely? I'd prefer to be using the methods as intended. The documentation since it's release has not been great so I thought it would be better to ask the wider community.
To try and explain better what I mean:
Building a custom block using the following method (<https://github.com/WordPress/gutenberg-examples/blob/master/03-editable/block.js>) of attributes with the --es5 flag appears to be more stable in terms of backwards compatibility. If I were to make changes to the render template (<https://github.com/WordPress/gutenberg-examples/blob/master/03-editable/index.php>) it wouldn't break the block.
Using the 'React' method (<https://github.com/WordPress/gutenberg-examples/blob/master/03-editable-esnext/src/index.js>), in my past experience, has caused issues. If I build a custom block using this method and a change has been made to the block's code, it 'kills' the block. There is no backwards compatibility from what I can tell.
I'm wondering if this is just something that has actually been resolved since the block editor was first introduced. Or is the way to continue building custom blocks is using the ES5 method
**One important bit I have missed out**
What I was originally alluding to is that I am using server side rendered blocks (excuse my terminology here, its not exactly a clear subject to those unfamiliar with it) that gets around the 'change anything in the block code and you have to add that block again in the editor' problem. Not Ideal for client handover.
```
register_block_type( 'create-block/perk', array(
'editor_script' => 'create-block-perk-block-editor',
'editor_style' => 'create-block-perk-block-editor',
'style' => 'create-block-perk-block',
'render_callback' => 'perk_block_render',
) );
function perk_block_render($attr, $content) {
$str = '';
if(isset($attr['mediaID'])) {
$mediaID = $attr['mediaID'];
$src = wp_get_attachment_image_src($mediaID, 'perk');
if($src && is_array($src) && isset($src[0])) {
$srcset = wp_get_attachment_image_srcset($mediaID);
$sizes = wp_get_attachment_image_sizes($mediaID, 'perk');
$alt = get_post_meta($mediaID, '_wp_attachment_image_alt', true);
if(!$alt) {
$alt = 'Perk icon';
}
}
}
if(isset($attr['titleContent'])) {
$title = $attr['titleContent'];
}
if(isset($attr['subContent'])) {
$subtitle = $attr['subContent'];
}
$str = "<div class='perks__item animate'>";
if($mediaID) {
$str .= "<img loading='lazy' width='170' height='170' src='{$src[0]}' alt='{$alt}'/>";
}
if($title) {
$str .= "<h2>{$title}</h2>";
}
if($subtitle) {
$str .= "<p>{$subtitle}</p>";
}
$str .= "</div>";
return $str;
```
}
I see now that it is not ES5/ESNext related, however, after looking through recent videos it seems like it is still an issue with developing custom blocks using WordPress's 'preferred' method. And also, judging by the answers using server-side-rendered blocks is the only way away this. Is my code going to experience issues if I continue to use server-side rendered blocks? | Whatever issues you had that caused a block to be "killed" after editing was entirely unrelated to the two different methods of writing the block that you have outlined.

The code in those two method is, for all intents and purposes, the same. They are just using different syntax.
The 'React' method (they're actually both React) is using some newer JavaScript features, but those are just nicer ways of writing the same code that work in newer browsers. That method also uses JSX for the render functions. This is just a different way of writing those functions which can be turned into functions exactly like the first example by a build process.
The issue you're describing is going to be a challenge of developing blocks regardless of which method you use. When a post built with the block editor is saved, the final output of your block is just saved into the post content as HTML. When the post is loaded back into the editor, your block needs to be able to parse that HTML and reconstruct the block data so that it can be edited again. If your block has changed since that HTML was published, it may not be able to do this and there will be an error. This is the expected behaviour.
The proper method for handling block updates without breaking existing posts is to 'deprecate' the block. The official documentation, with code examples, for that process is [here](https://developer.wordpress.org/block-editor/developers/block-api/block-deprecation/).
If you encountered this issue when using ESNext, but not ES5, then that is more than likely a coincidence. It would have had more to do with *what* you were doing than which method you were doing it with, as this behaviour is a consequence of how block data is stored, and nothing to do with the JavaScript version used to write the block.
It's worth pointing out that this is not a unique problem for the block editor. If I write a bunch of code in any system that works with data in a certain format, and then I update that code in a way that changes the format, I can't expect the code to just automatically work with data in the old format. You need to think of the HTML your block outputs as a format, and approach developing your block accordingly. |

The 'React' method (they're actually both React) is using some newer JavaScript features, but those are just nicer ways of writing the same code that work in newer browsers. That method also uses JSX for the render functions. This is just a different way of writing those functions which can be turned into functions exactly like the first example by a build process.
The issue you're describing is going to be a challenge of developing blocks regardless of which method you use. When a post built with the block editor is saved, the final output of your block is just saved into the post content as HTML. When the post is loaded back into the editor, your block needs to be able to parse that HTML and reconstruct the block data so that it can be edited again. If your block has changed since that HTML was published, it may not be able to do this and there will be an error. This is the expected behaviour.
The proper method for handling block updates without breaking existing posts is to 'deprecate' the block. The official documentation, with code examples, for that process is [here](https://developer.wordpress.org/block-editor/developers/block-api/block-deprecation/).
If you encountered this issue when using ESNext, but not ES5, then that is more than likely a coincidence. It would have had more to do with *what* you were doing than which method you were doing it with, as this behaviour is a consequence of how block data is stored, and nothing to do with the JavaScript version used to write the block.
It's worth pointing out that this is not a unique problem for the block editor. If I write a bunch of code in any system that works with data in a certain format, and then I update that code in a way that changes the format, I can't expect the code to just automatically work with data in the old format. You need to think of the HTML your block outputs as a format, and approach developing your block accordingly. |

384,526 | <p>I using plugin advanced custom fields to show recommended posts in my sidebar (posts that authors select as recommended using radio buttons (yes or no)).
And it is all working well.</p>
<p>Now, i will need to show that same recommended posts in my mobile application via json.</p>
<p>I found this amazing plugin: <a href="https://wordpress.org/plugins/acf-to-rest-api/" rel="nofollow noreferrer">https://wordpress.org/plugins/acf-to-rest-api/</a></p>

<p>And there i can see fields recommended_sidebar: yes or recommended_sidebar: no</p>
<p>But this JSON will show all posts (latest posts).
Is it possible to make some filter for posts?
I will like to show only posts that have recommended_sidebar: yes ?
Something like: <a href="https://www.domain.com/wp-json/wp/v2/posts?filter%5Brecommended_sidebar%5D=yes" rel="nofollow noreferrer">https://www.domain.com/wp-json/wp/v2/posts?filter[recommended_sidebar]=yes</a></p>
<p>If is not possible to create that filter via url, then only option is to create custom endpoint.
So i create this:</p>
<pre class="lang-php prettyprint-override"><code>add_action( 'rest_api_init', 'api_hooks' );
function api_hooks() {
register_rest_route( 'get-post-sidebar/v1', '/go', array(

function get_post_sidebar($request_data){
// $data = $request_data->get_params();
$data = array();
$args = array(

'post_status' => 'publish',
'orderby' => 'id',
'order' => 'DESC',
'meta_query' => array(
'relation' => 'OR',
array(
'key' => 'recommended_sidebar',
'value' => 'yes',
'compare' => '=',

),
'paged' => 1,
'posts_per_page' => 2,
);
$the_query = new WP_Query( $args );
while ( $the_query->have_posts() ) {
$the_query->the_post();
array_push($data,
array(
'title' => get_the_title(),
'content' => get_the_content(),

)
);
}
wp_reset_postdata();
$response = new \WP_REST_Response( $data );
$response->set_status( 200 );
return $response;
}
</code></pre>
<p>This this endpoint will show only sticky posts.
Also, it is set to:</p>
<pre class="lang-php prettyprint-override"><code> 'paged' => 1,
'posts_per_page' => 2,
</code></pre>
<p>But all sticky posts will show up in endpoint.</p>
<ul>
<li>if i change this value to:</li>
</ul>
<pre class="lang-php prettyprint-override"><code> 'paged' => 2,

<p>Then it will show 2 posts, but that 2 posts are sticky posts :(</p>
<ul>
<li>if i change this value to:</li>
</ul>
<pre class="lang-php prettyprint-override"><code> 'paged' => 2,
'posts_per_page' => 8,

an image can only be attached to one post</p>

<pre><code> <section class="hero" style="background-image:
url(<?php echo esc_url(wp_get_attachment_image_src(get_field('advanced_custom_fields_field'), 'full')[0]);
?>)">
</code></pre>
<p>When the window is resized (or website is opened on the phone), I would like to get the image from another <strong>advanced custom field entry</strong> (for example get_field('advanced_custom_fields_field <strong>_mobile</strong>') )</p>

] | I hope everyone is well!
I am looking for a possibility to load different galleries, background images etc for the phone and desktop. For example, I set my hero background image like this:
```
<section class="hero" style="background-image:
url(<?php echo esc_url(wp_get_attachment_image_src(get_field('advanced_custom_fields_field'), 'full')[0]);
?>)">
```
When the window is resized (or website is opened on the phone), I would like to get the image from another **advanced custom field entry** (for example get\_field('advanced\_custom\_fields\_field **\_mobile**') )
Is there a way to do it in php without js and ajax or is it the best way to do it with js?
Is there maybe a way to include advanced custom fields in a styles.php sheet with the header
```
header('Content-Type: text/css; charset:UTF-8');
```
If this was possible I could just write media queries here and include different images with get\_field() function, but I didn't find a way to access get\_field() function in style.php
Of course, this all can be achieved with js, but I am curious if there is a WP way of doing this.

Still i am getting the same error . Can somebody please let me know what i have done wrong ? | Step 1: Find the name of your wp-env container
First, you need to locate the name of the container created by wp-env. To do this, in the directory of your project containing .wp-env.json, you must run the following command:
```
docker ps
```
This should give you a list of containers. In the Names column, you’ll see the following information:
```
7b3099bc856ae9db898a196c0465cadb_wordpress_1
7b3099bc856ae9db898a196c0465cadb_tests-wordpress_1
7b3099bc856ae9db898a196c0465cadb_mysql_1
```
In this example, “7b3099bc856ae9db898a196c0465cadb” is the name of the container created by wp-env.
Step 2: Access the directory containing your docker-compose file
Once you have the name of your wp-env container, you can use it to access the directory containing the docker-compose file created by wp-env. To do so, run the following command in your terminal:
```
cd ~/.wp-env/7b3099bc856ae9db898a196c0465cadb
docker-compose down -v
docker-compose up -d
```
This should create a fresh environment.
Step 3: Restart wp-env
Finally, go back to your project folder and run:
```
wp-env start
```
You should then receive a message informing you that your WordPress dev environment is ready.

=========================================
Following along with [this question](https://wordpress.stackexchange.com/questions/296510/divi-change-project-slug-based-on-category) and [this one](https://wordpress.stackexchange.com/questions/212455/change-the-url-of-projects-in-divi-theme)
But can not get the desired outcome.

```

**What I want is:**
```

I have changed the slug of the project archive so that `example.com/stainless-steel-products/` is the project archive.
Below is the code used to achieve that.
```
// Change peralinks projects
function custom_project_slug () {

385,209 | <p>I am trying to let a user change their password via the API. What it looks like here is that I can send a POST request to the users endpoint with their user ID at the end, sending the new password in the request body as JSON. So,</p>
<p>POST to : <code>https://example.com/wp-json/wp/v2/users/123</code></p>
<p>And in the body:</p>
<pre><code>{
"password": "mySecretPassword"
}
</code></pre>
<p>In this case, the user is authenticated via JWT and needs to send the token in the header of the request.</p>
<p>When I tried this in postman, the request hangs for a really long time but finally seems to go through and the password is updated.</p>
<p>I wanted to know if I am doing this correctly, and if so why does it take so long?</p>

] | I am trying to let a user change their password via the API. What it looks like here is that I can send a POST request to the users endpoint with their user ID at the end, sending the new password in the request body as JSON. So,
POST to : `https://example.com/wp-json/wp/v2/users/123`
And in the body:
```
{
"password": "mySecretPassword"
}
```
In this case, the user is authenticated via JWT and needs to send the token in the header of the request.
When I tried this in postman, the request hangs for a really long time but finally seems to go through and the password is updated.

385,334 | <p>I want to show a popup to the first time visitor of a Wordpress site. I tried to check the visit state using <code>$_SESSION</code>. Something like this in the <em>footer.php</em>:</p>

if(($_SESSION['pxpop']) && (!is_user_logged_in()))

<?php dynamic_sidebar('msg-pop'); ?>
<?php endif; ?>
</div>
<?php
$_SESSION['pxpop']= false;
}

<p>with <code>session_start();</code> in the <code>init</code> hook of the functions.php.</p>
<p>But this is not working. <code>$_SESSION['pxpop']</code> remains <code>true</code> on each page load. So the popup opens on each page.</p>
<p>With a little r&d I have found that due to some 'statelessness' issue wordpress does not use sessions. From the site health section, it also says:</p>
<blockquote>
<p>"PHP sessions created by a session_start() function call may interfere
with REST API and loopback requests. An active session should be
closed by session_write_close() before making any HTTP requests."</p>
</blockquote>
<p>Then I tried implementing <code>$_COOKIE</code> too (in the <code>init</code> hook) as:</p>
<pre><code><?php
function pop_event()
{
if(!isset($_COOKIE['pxpop']))
{
setcookie('pxpop', true, 0);
//$_COOKIE['pxpop']= true;
}
if(($_COOKIE['pxpop']) && (!is_user_logged_in()))
{
?>
<div class="open_initpop">
<?php if(is_active_sidebar('msg-pop')): ?>
<?php dynamic_sidebar('msg-pop'); ?>
<?php endif; ?>
</div>
<?php
//unset($_COOKIE['pxpop']);
//$_COOKIE['pxpop']= false;
setcookie('pxpop', false, 0);
}
}
?>
</code></pre>
<p>But this is not working too...</p>
<p>What is wrong with my approach? What is the correct way to carry forward a value in Wordpress like PHP session without actually using it? Or using $_SESSION is the only resort?</p>

But this is not working too...
What is wrong with my approach? What is the correct way to carry forward a value in Wordpress like PHP session without actually using it? Or using $\_SESSION is the only resort? | Whoever has also the same question as I had:
This is how I got it to work:
```
add_filter('woocommerce_registration_redirect', 'custom_redirection_after_registration', 1);
function custom_redirection_after_registration( $redirection_url ){
// Change the redirection Url
add_action('wp_logout','only_redirect_unverfied_users_after_registration',1);
wp_logout();
wp_destroy_current_session();
$redirection_url = "https://...";
return $redirection_url;
}
function only_redirect_unverfied_users_after_registration(){
$redirection_url = "https://";
wp_redirect( $redirection_url);
exit();
}

I've created a child theme that enhances a popular parent theme. The enhancements include CSS, JS, and php. I want to use this child theme on multiple sites, and I want to allow for additional customization on each site without editing the child theme I created.
A few requirements:
* Each site uses the same base theme and a standard set of customizations (my child theme), but each site can have its own additional customizations (CSS, JS, and php).

My current solution is to create a directory outside the child theme that includes the CSS, JS, and php files for customizations, and then reference those in the child theme.

This is a plugin, a folder containing PHP/JS/CSS, with a comment at the top of one of the PHP files that has `/** Plugin Name: XYZ` at the top of the file.
```php
<?php
/**
* Plugin Name: XYZ
*/
```

**This isn't needed**. You can provide a hook/action/filter or use the existing hooks and filters WP provides. Including files directly from outside of the themes folder is bad practice and should never be necessary. In the long run it causes maintenance problems.

If you don't know then you can't know what to do, but that's okay. At some point you will need to update the child theme, and adding hooks is always good. The parent theme might do this too. Otherwise it's an unreasonable requirement, you can't know what you don't know.
### Custom JS and CSS
If you want to add extra javascript files and stylesheets to a theme without modifying the theme, you can do that in a plugin. Just enqueue the styles and scripts as you normally would.
WordPress doesn't see any difference between a style enqueued by a parent theme or a plugin, or itself. It's all just code that has been loaded into memmory. There is no such thing as a *plugin script*, or *theme style*, and no sandboxing, so nothing prevents you adding extra styles and scripts this way.
Perhaps if you wanted to add inline code tags I could understand, but there are APIs for this, e.g. `wp_add_inline_script`. If you really had to add it directly, there's hooks such as `wp_head` of `wp_footer` etc to do it on.
Custom PHP
----------
A plugin is by definition custom PHP. You can execute any custom PHP using a plugin.
If you wanted to replace a template with a new template from your plugin, you can do that too with the right filter. WooCommerce does it, lots of plugins do it, overiding specific templates or adding subfolders.

385,544 | <p>I am currently developing my first WordPress plugin and am currently a bit confused on how to change a record in a database.</p>
<p>So far I have solved it using the $wpdb::update() function:</p>
<pre><code>public function toggle_status() {
global $wpdb;
$id = (int) $_POST["id"];
$active = (int) $_POST["active"];
$tablename = $wpdb->prefix . 'myplugin_table';
$wpdb->update($tablename, array("active" => $active), array("id" => $id)); // Update record
}
</code></pre>
<p>Now I have learned that the way I change the database is not safe regarding SQL injection. I should rather use the $wpml::prepare() function:</p>
<pre><code>$wpdb->query($wpdb->prepare("UPDATE $tablename SET active = '%s' WHERE id = '%d'", array($active, $id)));
</code></pre>
<p>Is the $wpdb::update() function really not safe?</p>
<p>According to the documentation, this is not necessary for the $wpdb functions: "$data should be unescaped (the function will escape them for you). Keys are columns, Values are values." (<a href="https://codex.wordpress.org/Data_Validation#Database" rel="nofollow noreferrer">https://codex.wordpress.org/Data_Validation#Database</a>).</p>

] | I am currently developing my first WordPress plugin and am currently a bit confused on how to change a record in a database.
So far I have solved it using the $wpdb::update() function:
```
public function toggle_status() {
global $wpdb;
$id = (int) $_POST["id"];
$active = (int) $_POST["active"];
$tablename = $wpdb->prefix . 'myplugin_table';
$wpdb->update($tablename, array("active" => $active), array("id" => $id)); // Update record
}
```
Now I have learned that the way I change the database is not safe regarding SQL injection. I should rather use the $wpml::prepare() function:
```
$wpdb->query($wpdb->prepare("UPDATE $tablename SET active = '%s' WHERE id = '%d'", array($active, $id)));
```
Is the $wpdb::update() function really not safe?
According to the documentation, this is not necessary for the $wpdb functions: "$data should be unescaped (the function will escape them for you). Keys are columns, Values are values." (<https://codex.wordpress.org/Data_Validation#Database>). | It may helpful to you...

$video = (in_category ( 42 )) ? 'has-video' : '';
echo '<section id="cooked-recipe-list-' . $list_id_counter . '" class="cooked-clearfix cooked-recipe-' . $list_style . ' cooked-recipe-loader' . ( in_array( $list_style, $masonry_layouts ) ? ' cooked-masonry' : '' ) . ( isset($atts['columns']) && $atts['columns'] ? ' cooked-columns-' . $atts['columns'] : '' ) . ' ' . $video. '">';
```

<p>Anyway, I have built an image slider which changes the image and the description of the image on click of a button. Point be, I dynamically change the source of the img tag using javascript. But the images do not actually appear on the page.</p>
<p>The code holding the images is a simple array and I just iterate over each one Ie: <code>"images/work1.png"</code>, which works offline, but not via php and or wordpress.</p>
<p>This did not work, so I tried putting it in the php function instead: The javascript looks like:</p>
<pre><code>let imgArray = [
"<?php echo get_theme_file_uri('images/work1.png') ?>",
"<?php echo get_theme_file_uri('images/work2.png') ?>",
... etc
];
</code></pre>
<p>So the html looks like :
<code><img src="<?php echo get_theme_file_uri('images/work1') ?>"></code></p>
<p>The src tag's content is what changes but it does not take effect.</p>
<p>Any knowledge on why neither of those will actually work?
The code works because the associated text for each image still changes via click of the button. Just, the image refuses to display.</p>

``` | The problem is that you are trying to use PHP inside a javascript file. **PHP only works inside `.php` files.**
If you want to pass information to your javascript file from PHP, use `wp_localize_script` to store it in a variable, e.g. in a PHP file:
```php
$values = array(
'foo' => 'bar',
);
wp_localize_script( 'yourscripthandle', 'objectname', $values );
```
Now whenever the `yourscripthandle` script is enqueued, it will put those values at `window.objectname`.
You can accesss them like this in javascript:
```js
const values = window.objectname;
console.log( values.foo ); // prints 'bar'
```

] | I've been tasked with managing a WordPress site that was developed and configured by some other team. During a basic security scan, I've realized that the following end-point `https://www.mywordpress.com/wp-json` does not restrict the Origin for some reason.
```
curl -H "Origin: https://www.thewrongorigin.com" -I https://www.mywordpress.com/wp-json
HTTP/2 200
server: nginx
date: Mon, 22 Mar 2021 11:02:54 GMT
content-type: application/json; charset=UTF-8
vary: Accept-Encoding
access-control-expose-headers: X-WP-Total, X-WP-TotalPages, Link
access-control-allow-headers: Authorization, X-WP-Nonce, Content-Disposition, Content-MD5, Content-Type
allow: GET
access-control-allow-origin: https://www.thewrongorigin.com
access-control-allow-methods: OPTIONS, GET, POST, PUT, PATCH, DELETE
access-control-allow-credentials: true
… other headers here…
```
Looking at the response, and using different URLs as origin, it looks like that my WordPress installation is setting the header `access-control-allow-origin` to whatever the origin of the request is. I was expecting a response with the following header:
```
curl -H "Origin: https://www.thewrongorigin.com" -I https://www.mywordpress.com/wp-json
HTTP/2 200
...
access-control-allow-origin: https://www.mywordpress.com
```
What I want to do is modify my WordPress and set the header `Access-Control-Allow-Origin: https://www.mywordpress.com` for the URL `https://www.mywordpress.com/wp-json`.
My questions are:
* Is it okay to set restrict the origin in this way?
* What might be the consequences of doing it? Maybe plugins that rely on a header like `access-control-allow-origin: *` could stop working? Are there such plugins?
I've experience coding and working as a system administrator, but I'm fairly new to WordPress. | First of all, this is intentional behaviour, as relayed in a Slack discussion described in [this ticket](https://core.trac.wordpress.org/ticket/45477) (this has likely been discussed in other places, but that's the first I found):

So it should be noted that it's perfectly normal for `wp-json/` to be accessible from all origins, and it's not inherently insecure.

By modifying your WordPress install itself? ***Absolutely not.*** You should never edit WordPress core files. Any changes you make will be overwritten any time WordPress updates, forcing you to make the change again every time, possibly leading you into the very bad practice of maintaining your own fork of WordPress.
If you want to modify core WordPress behaviour yourself, you need to create a [plugin](https://developer.wordpress.org/plugins/), and use the [Hooks API](https://developer.wordpress.org/plugins/hooks/) to make your changes by removing and replacing actions, or filtering values.
In this case, you'll notice that the header is sent in the `rest_send_cors_headers()` function. This function is run by WordPress by hooking it with this line:
```
add_filter( 'rest_pre_serve_request', 'rest_send_cors_headers' );
```
Which, according to inline documentation is inside a function that is:
```
Attached to the {@see 'rest_api_init'} action to make testing and disabling these filters easier.
```
So, if you want to modify `rest_send_cors_headers()` what you need to to is create a plugin, and inside that plugin copy the `rest_send_cors_headers()` function to a new function with a different name. Then you want to replace WordPress' version with yours:
```
add_action(
'rest_api_init',
function() {
remove_filter( 'rest_pre_serve_request', 'rest_send_cors_headers' );
add_filter( 'rest_pre_serve_request', 'my_new_rest_send_cors_headers' );
}
);
```
Where `my_new_rest_send_cors_headers()` is the name of your new modified version of the function.

Most plugins are unlikely to have issues, as they will be making the requests from the same origin, however you will have issues with two types of plugins that I can think of:
1. Plugins that work with an external service. That service may want to connect to your website via the REST API, and will be unable to do so if you are only allowing requests from one origin.
2. Plugins that make requests to your site's REST API from the server, using curl, or the [WordPress HTTP API](https://developer.wordpress.org/plugins/http-api/), without setting the Origin header to your site's URL. This is pretty unusual and rare, but not impossible.
That last point brings up an important issue: Setting `Access-Control-Allow-Origin` is not going to protect your data. It is trivial for a server to spoof the origin and make a request to the API and get that data. This header is *not* an authentication security measure, so if you want to lock down your API from the outside world, this header is not the way to do it. |

<p>So I added a folder called 'label' under src, moved the index.js, save.js, edit.js, and stylesheets into the folder. I setup an index.js in the root and import that file. The block continues to work, even after the folder change with NPM running.</p>
<p>With the block working, both the plugin PHP file with register_block_type_from_metadata() and the block.json are still in the root directory. With NPM running, the block continues to work fine. I have the attributes only defined in block.json, and content is saving to those attributes, so I know it's 100% working.</p>
<p>However...when I move the block.json to the 'label' folder - like I see in core blocks and elsewhere, and as it makes sense so I can define more blocks - it breaks. I followed the docs of adding the path to the directory:</p>
<pre><code>function create_block_nutrition_facts_stacked_block_init() {
register_block_type_from_metadata(
__DIR__ . '/src/label'
);
}
</code></pre>
<p>Now the block isn't registered at all. I had renamed the label folder, so just as a test I moved the block.json to the root of the src folder and adjusted the path. Still not working. I took <strong>DIR</strong> out and gave it a direct path, I put the full file in (/src/label/block.json), I added and removed slashes and ./ and ../ and all kinds of things in case I'm just tired and was typing something wrong and it doesn't recognize it.</p>
<p>If I change it back to just <strong>DIR</strong> and move block.json back to the root, it works again fine. Attributes save. I've started and restarted NPM, I dug through tons of other plugins on Github, I dug through core plugins...I cannot find anyone using the new way of registering multiple blocks in a single plugin. Considering the "old way" will be depreciated according to the github pull request that merged block.json into the @wordpress/create-block...I'd really like to do it the "right" way here, but I'm stumped.</p>
<p>Any help is appreciated.</p>

I have the attributes only defined in block.json, and content is saving to those attributes, so I know it's 100% working.

Yes, you are.
[`$query->the_post()`](https://developer.wordpress.org/reference/classes/wp_query/the_post/) does *not* display anything — it just moves the pointer/key in the posts array (`$query->posts`) to the next one, and setups the global post data (`$GLOBALS['post']`). So yes, in response to your answer, [`the_content()`](https://developer.wordpress.org/reference/functions/the_content/) would be what you would use to display the content of the current post in the loop.
But actually, you could simply use the [`page_id` parameter](https://developer.wordpress.org/reference/classes/wp_query/#post-page-parameters) like so, to query a post of the `page` type and having a specific ID:
```php
$args = array(
// Instead of using post_type and post__in, you could simply do:
'page_id' => 1149,
);
```
Also, you should call [`wp_reset_postdata()`](https://developer.wordpress.org/reference/functions/wp_reset_postdata/) after your loop ends so that template tags (e.g. `the_content()` and `the_title()`) would use the main query’s current post again.
```php
while ($query->have_posts()) {
$query->the_post();
the_content();
}
wp_reset_postdata();
```
And just so that you know, you could also use [`get_post()`](https://developer.wordpress.org/reference/functions/get_post/) and [`setup_postdata()`](https://developer.wordpress.org/reference/functions/setup_postdata/) like so, without having to use the `new WP_Query()` way:
```php
//global $post; // uncomment if necessary
$post = get_post( 1149 );
setup_postdata( $post );
the_title();
the_content();
// ... etc.
wp_reset_postdata();

The key to doing this is scheduling the first job to run daily at the required time, and have that event create all of the other ones after it is done.
```
function wcs_cron_system_update($step = 0) {
switch ($step) {
case 0:
// do what has to be done first
break;
case 1:
// second step
break;
case 2:
// etc
break;
}
}
```
If you start like this, you can pass the `$step` as an argument to it. So on the daily cron it executes step 0.
After the first step is done, what you can do is call [`wp_schedule_single_event()`](https://developer.wordpress.org/reference/functions/wp_schedule_single_event/) like so
```
\wp_schedule_single_event(
// start in 5min
\current_time('timestamp') + (5 * 60),
'same_hook_as_daily_cron',
[1]
);
```
This will create an event for your second step. When that is done, just create a single event for your third step. Make sure [your `add_action` code allows for arguments](https://developer.wordpress.org/reference/functions/wp_schedule_single_event/#comment-1042). |
385,988 | <p>I am wondering how to add meta box in WordPress specific page admin, I mean when I create meta_box with code snippet below provided from source tutorial is really perfect and effective but one thing that I need to control is display that meta_box only in specific page for instance: pretend I have two page in my WordPress project named Home and About.</p>
<p>When I create meta_box by default the meta_box that I add will display on the same page admin back end, imagined when I clicked edit button to Home and About page my meta box will appear in both page. What I want is make a meta_box only show in “Home” admin backend page when I click the edit page.</p>
<p>My goal is set different meta_box in every different page, meaning the users specially the blog editor expect different meta_box_field in different page when they click edit button in each page, That is the thing I can’t figure out can you help me to solve that problem</p>

] | I am wondering how to add meta box in WordPress specific page admin, I mean when I create meta\_box with code snippet below provided from source tutorial is really perfect and effective but one thing that I need to control is display that meta\_box only in specific page for instance: pretend I have two page in my WordPress project named Home and About.
When I create meta\_box by default the meta\_box that I add will display on the same page admin back end, imagined when I clicked edit button to Home and About page my meta box will appear in both page. What I want is make a meta\_box only show in “Home” admin backend page when I click the edit page.
My goal is set different meta\_box in every different page, meaning the users specially the blog editor expect different meta\_box\_field in different page when they click edit button in each page, That is the thing I can’t figure out can you help me to solve that problem

Thank you for your support in advance. | Your conditional is in trouble.
`get_the_category()` returns an **object**, use foreach to find the specific category.
In addition, you assigned a value to the `$categories` variable, to compare you must use the [**comparison operators**](https://www.php.net/manual/en/language.operators.comparison.php) ( Ex: == or === )
I refactored the code and adapted it to your case, I hope it helps.

386,069 | <p>I wrote a WordPress theme for a non-profit where I use templates to style individual pages. I select the template for an individual page in the editor on the right:</p>
<p><a href="https://i.stack.imgur.com/znMdl.png" rel="noreferrer"><img src="https://i.stack.imgur.com/znMdl.png" alt="Template selection in editor" /></a></p>
<p>For styling of a template page, I simply add a css class to the outer most element in the template and style the rest based on the presence of this class - in this example <code>layout-krankenbett-gruen</code>:</p>
<p><strong>templates/KrankenbettGruen.php</strong>:</p>
<pre><code><?php /* Template Name: Krankenbett grün */ ?>
<?php get_header(); ?>
<main class="layout-krankenbett-gruen">
<?php if ( have_posts() ) : while ( have_posts() ) : the_post();
get_template_part( 'content', get_post_format() );
endwhile; endif; ?>
</main>
<?php get_footer(); ?>
</code></pre>
<p>I can style the page similar to the display in the editor using this code in <code>functions.php</code></p>
<pre><code>// enable style sheet for normal page display also in editor
add_theme_support('editor-styles');
add_editor_style('style.css');
</code></pre>
<p>such that all styles that get applied to the page get also applied in the editor.</p>
<p>I want to have the editor also show the templates as they look on the page later.
But somehow the css tag which I add for the template is not present in the editor and therefor the display of the template in the editor is not correct.</p>
<p>How can I recognize a template in the editor such that I can display it in the editor in the same style as on the page?</p>
<p><strong>Update:</strong></p>
<p>I saw that the Twenty Twenty Theme also has Templates (Standard-Template, Cover-Template and Template for wide pages). If I change the template in this Theme, the page in the editor does not change, but the page itself does. Is that intended behavior? I feel like the user would like to see how a template looks (in the editor) before he applies it. Am I getting it wrong?</p>

] | I wrote a WordPress theme for a non-profit where I use templates to style individual pages. I select the template for an individual page in the editor on the right:
[](https://i.stack.imgur.com/znMdl.png)
For styling of a template page, I simply add a css class to the outer most element in the template and style the rest based on the presence of this class - in this example `layout-krankenbett-gruen`:
**templates/KrankenbettGruen.php**:
```
<?php /* Template Name: Krankenbett grün */ ?>
<?php get_header(); ?>
<main class="layout-krankenbett-gruen">
<?php if ( have_posts() ) : while ( have_posts() ) : the_post();
get_template_part( 'content', get_post_format() );
endwhile; endif; ?>
</main>
<?php get_footer(); ?>
```
I can style the page similar to the display in the editor using this code in `functions.php`
```
// enable style sheet for normal page display also in editor
add_theme_support('editor-styles');
add_editor_style('style.css');
```
such that all styles that get applied to the page get also applied in the editor.
I want to have the editor also show the templates as they look on the page later.
But somehow the css tag which I add for the template is not present in the editor and therefor the display of the template in the editor is not correct.
How can I recognize a template in the editor such that I can display it in the editor in the same style as on the page?
**Update:**
I saw that the Twenty Twenty Theme also has Templates (Standard-Template, Cover-Template and Template for wide pages). If I change the template in this Theme, the page in the editor does not change, but the page itself does. Is that intended behavior? I feel like the user would like to see how a template looks (in the editor) before he applies it. Am I getting it wrong? | welcome to this forum. :-)
I'm not an expert, BUT I did do something similar by following the instructions and tutorials I found at these links below, hopefully these will help guide you.
In a nutshell, you have to go beyond just enabling the stylesheet in the editor, you have actually add a stylesheet specifically for the editor (editor-styles.css) and declare your styles in that (being sure to keep them the same as your front-facing style.css file).
Also, way below I put my own code if it also helps to serve as an example.
Good luck!!

Any guidance much appreciated. | The HTML of a WordPress page is a mix of many sources. Parts of it come from plugins, other parts from the main template, others from the database, others from the core. They can also come from widgets, template options, and so on.
Unfortunately, WordPress pages are not on specific files that you can open and edit their HTML.
In most cases, the pages are Frankensteins' monsters built from many different sources programmatically. And that's not a bad thing - the power of WordPress comes from its extensibility, which is a consequence of this design.
To change an HTML on WordPress, you need to track what is generating that HTML. Then, you modify it - either via the admin dashboard or programmatically (not by writing a bunch of HTML, but by calling PHP functions and methods).
If you are lucky, you may be able to change what you want on the admin dashboard with no code.
If the content you want to change is not changeable through the admin dashboard, you will need to do some coding. As you pointed, it would be best if you use child themes to avoid updates to overwrite your changes.
But if you got to this point, you need to understand how to code for WordPress first. You need to understand hooks, actions, filters, and so on.
A good recommendation is the book "Professional WordPress Plugin Development" by Ozh Richard. He is famous in the community and even referred to on the official WordPress documentation. But be aware that the learning curve can take some time. |
386,514 | <p>I've written a custom plugin, <code>ta-intentclicks</code> which is used as a shortcode:</p>
<pre><code>[ta-intentclicks count="3" category="SEC-EDR"...]
</code></pre>

[ta-intentclicks-link url="$list_item['link']"]<img src="foo" />[/ta-intentclicks-link]

I've seen examples of people calling "do\_shortcode" to execute a shortcode, but I'm unclear where the shortcode function goes in my case, OR where to place the "do\_shortcode" call.
Can anyone offer guidance here? This is my first plugin and I'm a bit lost as to how and implement this functionality. Thanks in advance. | If I understand it correctly, inside the *shortcode template*, you could do something like this:
```php
echo do_shortcode( '[ta-intentclicks-link url="' . esc_url( $list_item['link'] ) . '"]Visit website[/ta-intentclicks-link]' );
```
But then, **instead of having to use [`do_shortcode()`](https://developer.wordpress.org/reference/functions/do_shortcode/)**, you could actually simply call the shortcode callback from the (shortcode) template ( which then eliminates the need to find and parse shortcodes in the content or the first parameter for `do_shortcode()` ):
* If you registered the shortcode like so:
```php
add_shortcode( 'ta-intentclicks-link', 'my_shortcode' );
function my_shortcode( $atts = array(), $content = null ) {
$atts = shortcode_atts( array(
'url' => '',
), $atts );
if ( ! empty( $atts['url'] ) ) {
return sprintf( '<a href="%s" target="_blank">%s</a>',
esc_url( $atts['url'] ), esc_html( $content ? $content : $atts['url'] ) );
}
return '';
}
```
* Then in the shortcode template, you could simply call the `my_shortcode()` function above:
```php
echo my_shortcode( array(
'url' => $list_item['link'],
), 'Visit website' );
```
But if that's not what you meant, or if you had a shortcode in a shortcode like `[caption]Caption: [myshortcode][/caption]`, then as said in the [Shortcode API on the WordPress Codex website](https://codex.wordpress.org/Shortcode_API#Enclosing_vs_self-closing_shortcodes):
>
> If the enclosing shortcode is intended to permit other shortcodes in
> its output, the handler function can call

> function caption_shortcode( $atts, $content = null ) {
> return '<span class="caption">' . do_shortcode($content) . '</span>';
> }
>
> ```
>
>
... your `run()` function (or the shortcode callback) would need to capture the second parameter passed to the function, i.e. `$content` as you could see above, and once you have that parameter (or its value), you can then call `do_shortcode()`.
(With the above "caption" shortcode example, the `$content` is the `Caption: [myshortcode]`.)
So for example, your `run()` function be written like so…
```php
// 1. Define the $content variable.
function run( $attributes = [], $content = null ) {
// ... your code (define $response, $layoutAttributes, $dataAttributes, etc.)
// 2. Then do something like so:
return $this->layout->render( $response, $layoutAttributes, $dataAttributes ) .
do_shortcode( $content );
}
```
But if you need further help with that, do let me know in the comments (and preferably, please show the code in your template and explain the variables like the `$response` and `$layoutAttributes`). |

I saw tips about "Last modified by/date" feature but I need to **show the table of all changes (revisions) done on post (Date/author/content- if possible).**
It's formally required for public institutions and I'm bit surprised there are nothing on Google.
Is there a way to do that? | There are many ways to do it, without third party plugins:
Shortcode
---------
**Cons**: shortcode has to be created, and added to all posts.
Child theme template
--------------------
**Cons**: theme dependent, and right template has to be modified.
Child theme functions.php
-------------------------
**Cons**: theme dependent.
Plugin in mu-plugins
--------------------
**Cons**: none.
**Pros**: not theme dependent, easiest to implement.
### Implementation
Create file `post-with-revisions.php`, with the following content, and place it in `wp-content/mu-plugins`:
```
<?php
function wpse_single_post_with_revisions( $content ) {
// Check if we're inside the main loop in a single Post.
if ( is_singular() && in_the_loop() && is_main_query() ) {
$content .= '<h2>Revisions</h2>';
$revisions = wp_get_post_revisions();
foreach ( $revisions as $rev ) {
$date = $rev->post_date;
$author = get_author_name( $auth_id = $rev->post_author );
$content .= '<h4>' . $date . ' by ' . $author . '</h4>';
$content .= $rev->post_content;
}
}
return $content;
}
add_filter( 'the_content', 'wpse_single_post_with_revisions' );
```
**Note**: revisions will be visible in single post only, not in archives.
UPDATE
------
For easier identification of changes between revisions, instead of displaying the content of revisions, we can display differences between them. The modified code follows:
```
<?php
function wpse_single_post_with_revisions( $content ) {
global $post;
// Check if we're inside the main loop in a single Post.
if ( is_singular() && in_the_loop() && is_main_query() ) {
$content .= '<h2>Revisions</h2>';
$revisions = wp_get_post_revisions();
$ids_to_compare = array();
foreach ( $revisions as $rev ) {
$date = $rev->post_date;
$author = get_author_name( $auth_id = $rev->post_author );
$id = $rev->ID;
array_push( $ids_to_compare, (int) $id );
$content .= '<strong>ID: ' . $id .' - ' . $date . ' by ' . $author . '</strong><br>';
//$content .= $rev->post_content;
}
$content .= '<h2>Diffs</h2>';
require 'wp-admin/includes/revision.php';
for ( $i = 0; $i <= count( $ids_to_compare ) - 2; $i++ ) {
$diffs = wp_get_revision_ui_diff( $post, $ids_to_compare[$i], $ids_to_compare[$i + 1] );
$content .= '<h3>' . $ids_to_compare[$i] . ' to ' . $ids_to_compare[$i + 1] . '</h3>';
if ( is_array( $diffs ) ) {
foreach ( $diffs as $diff ) {
$content .= $diff['diff'];
}
}
$content .= '<hr>';
}
}
return $content;
}

For your code to function, it would require either `add_action` to implement time travel several microseconds into the past so that it can add the hook before it ran, or it would require `do_action` to implement precognition so that it knows about `add_action` calls in the future that have not happened yet.
By putting your `add_action` call in `home.php` or other templates that occur *after* the `header.php` runs, you are telling WordPress to execute code when a hook fires that has already fired.

```
function wpse_all_capabilities() {

] | I bought woocommerce compare plugin. Unfortunately I can't understand how to apply some filters.
For example I want to increase compare limit tom 10. How ı can use below filte?
apply\_filters( ‘woocommerce\_products\_compare\_max\_products’, int ) – sets how many products can be compared at one time. Default is 5.
What I tried but not working;
```
function comparelimit($location){
$location = 10;
}
apply_filters( ‘woocommerce_products_compare_max_products’, 'comparelimit');

best, Aprilia | I had a quick look at the [site-branding template part](https://themes.trac.wordpress.org/browser/twentytwentyone/1.3/template-parts/header/site-branding.php) which handles the rendering of the custom logo on the site header. There's a conditional check on two lines against `has_custom_logo()`, along show title theme mod, which determines, if the custom logo should be rendered or not.
Internally `has_custom_logo()` calls `get_theme_mod( 'custom_logo' )` to figure out, if a custom logo has been set. This means, you can use the [theme\_mod\_{$name}](https://developer.wordpress.org/reference/hooks/theme_mod_name/) filter to change 1) the value of the theme mod and 2) the result of `has_custom_logo()`.
As code the above would be something like this,
```
function prefix_disable_logo_on_front_page( $value ) {
return is_front_page() ? false : $value;
}
add_filter('theme_mod_custom_logo', 'prefix_disable_logo_on_front_page');

And here's an example which changes the description of the Akismet plugin:
```php
add_filter( 'all_plugins', 'my_all_plugins' );
function my_all_plugins( $all_plugins ) {
// the & means we're modifying the original $all_plugins array

if ( 'Akismet Anti-Spam' === $plugin_data['Name'] ) {
$plugin_data['Description'] = 'My awesome description';
}
}
return $all_plugins;
}
```

``` | You need to read the documentation, [`get_sidebar()`](https://developer.wordpress.org/reference/functions/get_sidebar/):
>
> Includes the sidebar template for a theme or if a name is specified then a specialised sidebar will be included.

Its purpose is to load `sidebar.php`. It does not output widgets. To output widgets you need to use `dynamic_sidebar()`:
```
<?php dynamic_sidebar( 'sidebar-1' ); ?>
```
That will output the widgets added to that widget area. This is clearly outlined in [the documentation](https://developer.wordpress.org/themes/functionality/sidebars/#displaying-sidebars-in-your-theme). |

The only real answer to this question can be given by looking at the code and following what goes on.
And after reading it for a few hours, here is what I can say about it:
>
> WP Query sanitizes the values but it doesn't do it all in one place. Values are being sanitized before they are actually used. It's a very organic and *on the go* approach. Also, not all of the values are sanitized, but in those cases a prepared statement is used for the SQL query.
>

Let's get into detail
---------------------
So, what happens when we do:
```
$query = new WP_Query($args);
```
The WP\_Query class constructor checks if the `$args` is an empty array or not. And if it's not, it will run its `query()` method passing the `$args` array (which is at this point called `$query` array).
```
$this->query($query);
```
The `query()` method calls the `init()` method which unsets possible previous values and sets new defaults.
Then it runs [wp\_parse\_args()](https://developer.wordpress.org/reference/functions/wp_parse_args/) on the `$args` array. This function does not sanitize anything, it serves like a bridge between default data and input data.
The next call is for the `get_posts()` method, which is in charge of retrieving the posts based on the given query variables.
The first thing that is called inside the `get_posts()` method is the `parse_query()` method, which starts by calling the `fill_query_vars()` method (this one makes sure that a list of default keys are set. The ones that are not, get set with an empty string or empty array depending on the case).
Then, still inside the `parse_query()` method, the first santization takes place.
`p` is checked against [is\_scalar()](https://www.php.net/manual/en/function.is-scalar.php) and cleaned with [intval()](https://www.php.net/manual/en/function.intval.php)
Also [absint()](https://developer.wordpress.org/reference/functions/absint/) is used on the following values:
```
page_id
year
monthnum
day
w
paged
hour
minute
second
attachment_id
```
Also, a `preg_replace('|[^0-9]|'...)` is run on `m`, `cat`, `author` to only allow comma separated list of positive or negative integers on these.
For other values at this point, only the trim() function is used. This is the case for:
```
pagename
name
title
```
After this, the method starts checking what type of query we are running. Is it a search? An attachment? A page? A single post? ...
If a `pagename` is set then we call (without sanitizing the value) `get_page_by_path($qv['pagename'])`. But checking that function source we can see that the value is sanitized with [esc\_sql()](https://developer.wordpress.org/reference/functions/esc_sql/) **before it's used for a database request**.
After that, we can see that when the keys `post_type` or `post_status` are used, they are both sanitized with [sanitize\_key()](https://developer.wordpress.org/reference/functions/sanitize_key/) (Only lowercase alphanumeric characters, dashes, and underscores are allowed).
For the taxonomy related parameters, the `parse_tax_query()` method is called.
`category__and`, `category__in`, `category__not_in`, `tag_id`, `tag__in`, `tag__not_in`, `tag__and` are sanitized with [absint()](https://developer.wordpress.org/reference/functions/absint/)
`tag_slug__in` and `tag_slug__and` are sanitized with [sanitize\_title\_for\_query()](https://developer.wordpress.org/reference/functions/sanitize_title_for_query/)
At this point the `parse_query()` method is over, but we still are inside the `get_posts()` method.
`posts_per_page` is sanitized.
`title` is being used unsanitized but with a [prepared statement](https://www.php.net/manual/en/mysqli.prepare.php). You may find this question interesting: [Are prepared statements enough to prevent SQL injection?](https://stackoverflow.com/questions/134099/are-pdo-prepared-statements-sufficient-to-prevent-sql-injection)
Then we have `post__in` and `post__not_in` that are being sanitized with [absint()](https://developer.wordpress.org/reference/functions/absint/).
And if you keep reading the code and pay attention, you will see that all the keys are actually being sanitized before they get to touch a SQL statement or a prepared statement is used instead.
So, to answer your original question:
**Does WordPress sanitize arguments to WP\_Query?**
It does sanitize most of them but not all. For example, `pagename`, `name` and `title` are only "cleaned" with the [trim()](https://www.php.net/manual/en/function.trim.php) function (does not return SQL safe values!). But for the values that are not sanitized, a prepared statement is used to perform the database request.
Should you trust this?
----------------------
Well, in this specific case I would prefer to go for the possibly **redundant** just presanitize everything approach before you throw it into the query.
Me too, as an engineering student, I would love a solid yes or no answer. But note that the WordPress codebase has evolved in a natural way so it's just like nature: *messy*. It does not mean it's bad. But messy means that there could be an unseen edge-case where somebody could potentially sneak in with a bomb. And you can prevent that by just doubling your guards! |

Let's get into detail
---------------------
So, what happens when we do:
```
$query = new WP_Query($args);
```
The WP\_Query class constructor checks if the `$args` is an empty array or not. And if it's not, it will run its `query()` method passing the `$args` array (which is at this point called `$query` array).
```
$this->query($query);
```
The `query()` method calls the `init()` method which unsets possible previous values and sets new defaults.
Then it runs [wp\_parse\_args()](https://developer.wordpress.org/reference/functions/wp_parse_args/) on the `$args` array. This function does not sanitize anything, it serves like a bridge between default data and input data.
The next call is for the `get_posts()` method, which is in charge of retrieving the posts based on the given query variables.
The first thing that is called inside the `get_posts()` method is the `parse_query()` method, which starts by calling the `fill_query_vars()` method (this one makes sure that a list of default keys are set. The ones that are not, get set with an empty string or empty array depending on the case).
Then, still inside the `parse_query()` method, the first santization takes place.
`p` is checked against [is\_scalar()](https://www.php.net/manual/en/function.is-scalar.php) and cleaned with [intval()](https://www.php.net/manual/en/function.intval.php)
Also [absint()](https://developer.wordpress.org/reference/functions/absint/) is used on the following values:
```
page_id
year
monthnum
day
w
paged
hour
minute
second
attachment_id
```
Also, a `preg_replace('|[^0-9]|'...)` is run on `m`, `cat`, `author` to only allow comma separated list of positive or negative integers on these.
For other values at this point, only the trim() function is used. This is the case for:
```
pagename
name
title
```
After this, the method starts checking what type of query we are running. Is it a search? An attachment? A page? A single post? ...
If a `pagename` is set then we call (without sanitizing the value) `get_page_by_path($qv['pagename'])`. But checking that function source we can see that the value is sanitized with [esc\_sql()](https://developer.wordpress.org/reference/functions/esc_sql/) **before it's used for a database request**.
After that, we can see that when the keys `post_type` or `post_status` are used, they are both sanitized with [sanitize\_key()](https://developer.wordpress.org/reference/functions/sanitize_key/) (Only lowercase alphanumeric characters, dashes, and underscores are allowed).
For the taxonomy related parameters, the `parse_tax_query()` method is called.
`category__and`, `category__in`, `category__not_in`, `tag_id`, `tag__in`, `tag__not_in`, `tag__and` are sanitized with [absint()](https://developer.wordpress.org/reference/functions/absint/)
`tag_slug__in` and `tag_slug__and` are sanitized with [sanitize\_title\_for\_query()](https://developer.wordpress.org/reference/functions/sanitize_title_for_query/)
At this point the `parse_query()` method is over, but we still are inside the `get_posts()` method.
`posts_per_page` is sanitized.
`title` is being used unsanitized but with a [prepared statement](https://www.php.net/manual/en/mysqli.prepare.php). You may find this question interesting: [Are prepared statements enough to prevent SQL injection?](https://stackoverflow.com/questions/134099/are-pdo-prepared-statements-sufficient-to-prevent-sql-injection)
Then we have `post__in` and `post__not_in` that are being sanitized with [absint()](https://developer.wordpress.org/reference/functions/absint/).
And if you keep reading the code and pay attention, you will see that all the keys are actually being sanitized before they get to touch a SQL statement or a prepared statement is used instead.
So, to answer your original question:
**Does WordPress sanitize arguments to WP\_Query?**
It does sanitize most of them but not all. For example, `pagename`, `name` and `title` are only "cleaned" with the [trim()](https://www.php.net/manual/en/function.trim.php) function (does not return SQL safe values!). But for the values that are not sanitized, a prepared statement is used to perform the database request.
Should you trust this?
----------------------
Well, in this specific case I would prefer to go for the possibly **redundant** just presanitize everything approach before you throw it into the query.
Me too, as an engineering student, I would love a solid yes or no answer. But note that the WordPress codebase has evolved in a natural way so it's just like nature: *messy*. It does not mean it's bad. But messy means that there could be an unseen edge-case where somebody could potentially sneak in with a bomb. And you can prevent that by just doubling your guards! |

A Longer Answer
---------------
The first parameter (which is the nonce action) for `check_ajax_referer()` needs to match the first parameter for [`wp_create_nonce()`](https://developer.wordpress.org/reference/functions/wp_create_nonce/), but in your code, they are `secure-nonce-name` and `secure_nonce_name` respectively, hence that would result in the error 403 which basically means "invalid nonce".
So make sure the names are equal or that the nonce action is correct, e.g. use `secure_nonce_name` with both the above functions:
```php
// In the script in javascript_variables():
var ajax_nonce = '<?php echo wp_create_nonce( "secure_nonce_name" ); ?>';
// Then in the AJAX callback (send_form()):
check_ajax_referer( 'secure_nonce_name', 'security' );

] | I am using get\_users() to return a list of users with specified roles. The purpose of this is to generate a dropdown on the front end to mention other users in comments, very similar to the functionality of <https://wordpress.org/plugins/comment-mention/>.
The problem is that if the current user is in a lower role, such as an author, get\_users() does not return higher roles, such as an administrator. In other words, I need a lower user to be able to return users of higher roles as well.
I realised that get\_users() prevents return higher role users from here: [get\_users / WP\_User\_Query returns empty when logged out](https://wordpress.stackexchange.com/questions/354939/get-users-wp-user-query-returns-empty-when-logged-out)
But I wondered if there was a way around this. This is how I am getting the list of users at the moment
```
<?php
// Set arguments.
$args = array(
'fields' => array('user_login'),
'role__in' => array('administrator','editor','author'),
);
// Get usernames.
$results = get_users( $args );
?>
```
*Just a note here, the desired final result is to return an array of all usernames.* | **Short answer — how can you solve the problem:** When you call [`check_ajax_referer()`](https://developer.wordpress.org/reference/functions/check_ajax_referer/), use `secure_nonce_name` as the first parameter, i.e. `check_ajax_referer( 'secure_nonce_name', 'security' )`.
A Longer Answer
---------------
The first parameter (which is the nonce action) for `check_ajax_referer()` needs to match the first parameter for [`wp_create_nonce()`](https://developer.wordpress.org/reference/functions/wp_create_nonce/), but in your code, they are `secure-nonce-name` and `secure_nonce_name` respectively, hence that would result in the error 403 which basically means "invalid nonce".
So make sure the names are equal or that the nonce action is correct, e.g. use `secure_nonce_name` with both the above functions:
```php
// In the script in javascript_variables():
var ajax_nonce = '<?php echo wp_create_nonce( "secure_nonce_name" ); ?>';
// Then in the AJAX callback (send_form()):
check_ajax_referer( 'secure_nonce_name', 'security' );
```
Additional Notes
----------------
* You should consider using the [REST API](https://developer.wordpress.org/rest-api/) which, unlike the `admin-ajax.php`, gives a better, human-friendly message when an error is encountered while processing the request. |

I really am confused about how the Wordpress editor handles the state for publishing and confused why it's not returning the meta and featured image. I found this user having the same issue(I think) with the same hook and isn't resolved either <https://stackoverflow.com/questions/35666305/get-featured-image-url-after-publishing>
I have also done a recording of this <https://share.getcloudapp.com/eDujbqJp>
I hope someone can advise or give direction regarding this. Thank you in advance | >

The hook itself works, and if you used the old WordPress post editor, then the issue in question would **not** happen.
So you can say that it's the Gutenberg/block editor.

Because Gutenberg uses the REST API, and by the time the `publish_post` hook is fired (when `wp_update_post()` is called — see [source](https://core.trac.wordpress.org/browser/tags/5.7.1/src/wp-includes/rest-api/endpoints/class-wp-rest-posts-controller.php#L808)), the post's featured image and other meta data have not yet been saved/processed.
How to fix the issue
--------------------
*If you're using WordPress **5.6** or later*, then for what you're trying to do, you would want to use the [`wp_after_insert_post` hook](https://developer.wordpress.org/reference/hooks/wp_after_insert_post/) which works well with the old/classic editor and the Gutenberg/block editor.
Excerpt from <https://make.wordpress.org/core/2020/11/20/new-action-wp_after_insert_post-in-wordpress-5-6/>:
>
> New action wp\_after\_insert\_post in WordPress 5.6.

> * `$post_before` The full post object prior to the update, a `WP_Post` object. For new posts this is `null`.
>
>
>
And here's an example which mimics the `publish_post` hook, i.e. the `// your code here` part below would only run if the post is being published and is *not* already published (the post status is not already `publish`):
```php
add_action( 'wp_after_insert_post', 'my_wp_after_insert_post', 10, 4 );
// Note: As of writing, the third parameter is actually named $update and not $updated.
function my_wp_after_insert_post( $post_id, $post, $update, $post_before ) {
if ( 'publish' !== $post->post_status ||
( $post_before && 'publish' === $post_before->post_status ) ||
wp_is_post_revision( $post_id )
) {
return;
}
// your code here
}
