ACF - Eliminate unnecessary data and print
In ACF, the_field('battery'); outputs as follows :
Battery : Sony Rechargeable Ni-MH 2200 mAh battery
or
Battery : Energizer AA Rechargeable Batteries 2300 mAh NiMH
How can i achieve this (showing only mAh details) :
Battery : 2200 mAh
or
Battery : 2300 mAh | You have to use a regex, in this case, to extract the needed value from a string:
$string = 'Energizer AA Rechargeable Batteries 2300 mAh NiMH';
preg_match('/([0-9]+\s*mah)/i', $string, $capacity );
if ( isset( $capacity[0] ) ) {
printf('Battery: %s', $capacity[0] );
}
This regex `/([0-9]+\s*mah)/i` will look for any numbers followed by case insensitive `mah` combination.
You can test this regex online here <

Number format for wp_count_posts()
I'm trying to format my post my total post count in the header of my site. I have the number in there but would like it to format with the commas eg 1,500 not 1500. I know this is probably really basic but I'm still learning.. any help would be much appreciated. Cheers

function wpb_total_posts() {
$total = wp_count_posts()->publish;

',' // thousands separator
);

Change page name in admin list
One of my customer has many pages that have the same titles, although their content is different.

How to exclude a category returned by get_categories from function.php?
I have a plugin that create my website sitemap. It starts by getting all categories with `get_categories` and then gets all pages for each. However I have one category that must not be included then I did that in the plugin code:
$args['exclude']=2;
$cats = get_categories( $args );
The problem is that if the plugin replace the file my modiofication will be deleted, I tried with that:
function exclude_cat($taxonomy, $args) {
$args['exclude']=2;
return $args;
}
add_filter('get_categories_taxonomy', 'exclude_cat', 10, 2);
But then no category is returned at all, I think I'm not using it correctly but I don't find examples. | You'll find an appropriate filter in the `get_terms` function which is called by `get_categories`.
See source code <
We don't use any of the callback arguments in this case. We can use `array_filter` on the list of terms (WP_Term) objects. See <
This allows us to remove a term with a particular ID
add_filter( 'get_terms', function( $terms, $taxonomies, $args, $term_query ){
return array_filter($terms, function( $term ) {
return $term->term_id !== 2;
});
}, 10, 4 );
Note that `get_categories` by default only returns categories which have posts assigned, you can change that by adding `hide_empty => false` to the `$args` array. | stackexchange-wordpress | {

post_type internal ID?
This may sound like a stupid question, but is there something like an ID associated with the post types (built in or custom) in WordPress?
I'm not interested in the actual post id, but wondering if there's something like this:
ID Post type slug
-------------------------
0 post
1 page
2 slider
3 section
...
What I would need would be something like `get_post_type_id( $post_type_slug )` so that when I call `get_post_type_id( 'slider' )` it would return `2`.
The reason: I'm building a post slider shortcode and I need a unique ID that could be in the form of `#{$post_type}-slider-{$id}`, to avoid duplicates and correctly apply JavaScript.
Thanks! | **No there isn't, and it isn't necessary. Post type names are their own unique identifiers.**
The primary reason there are no numeric IDs is because post types are registered on every page load in PHP, no table exists in the database for them, which means no row IDs. So there is no use for a unique ID that the post name doesn't already accomplish.
For this reason, you're perfectly fine to use the post types name in your ID attributes, post type names can't clash.
The same is true of taxonomy names, 2 taxonomies cannot share the same name. | stackexchange-wordpress | {

Show admin menu and toolbar in admin post page
Is there a way to still show the **admin toolbar** and/or the main wordpress **admin menu** in the admin post page?
, and which is intended to help users to work without distraction.
Secondly, there's also a note in `wp-admin/admin-header.php` which says that `// Default to is-fullscreen-mode to avoid jumps in the UI.` — `is-fullscreen-mode` is a CSS class added to the `<body>` tag indicating a full-screen mode. Therefore, the default mode should not be changed (programmatically).
However, once the page has been loaded, you can turn off the full-screen mode by simply clicking on the three-dot button (which shows " _More tools & options_" when mouse-overed) on the top-right corner of the screen, and from the menu that appears, just click on the " **Fullscreen mode** " option:
![Toggle the Fullscreen mode in the block editor]( "A preview on WordPress 5.5.1")

How to dequeue wp_get_custom_css in Twenty Twenty Theme
How to remove Additional CSS from loading. It loads as internal style sheet on every page. I am doing this but it is not working. if I
`print_r(wp_get_custom_css());` It shows the same css. I want to disable it to load.
add_action( 'wp_enqueue_scripts', 'mywptheme_child_deregister_styles', 11 );
function mywptheme_child_deregister_styles() {
wp_dequeue_style( 'wp-custom-css' );
}
` and it's hooked to `wp_head` like so:
add_action( 'wp_head', 'wp_custom_css_cb', 101 );
Which adds the custom/additional CSS in the document `head`.
So if you don't want that to happen — or you'd rather add/load the CSS manually, you can add this to your theme `functions.php` file:

Adding post fields in wp-json/wp/v2/search
I am trying to add the post (pages, posts) excerpt in the `wp-json/wp/v2/search` get endpoint but this endpoint seems to not take into account the `register_rest_field` method.

Can I pass parameters to the add_shortcode() function?

How to fix mime-type and (after disabling nosniff) 404 errors for css and js files in staging site
I set up a staging site from the live site with my hosting, A2 Hosting. The pages are all messed up, and in the browser console, I could see lots of mime type errors (photo for examples). The errors come from CSS and JS files from all the plugins and theme.
 and some things started being served, but many were still giving 404s.
2. There was a rewrite rule in .htaccess designed to prevent hotlinking things in wp-content, allowing google and my site only. That was not updated to the staging URL during creation of the staging. So the staging site was blocking itself!

Differentiation between index.php and page.php
I am currently developing a theme in wordpress for learning purposes.
To set out to you my page hierarchy I have the following:
* index.php: fallback for all website pages
* home.php: blog page
* front-page.php: static front page
* page.php: default fallback for individual pages
* single.php: single post page
* header.php and footer.php
I wanted to know what difference between an index.php and a page.php should display?
On my index.php, I have only the header(); and footer(); functions.
On my page.php, I have my main content div with the standard loop that outputs my page posts from wordpress, with the exclusion of the header and footer functions
Would my index and page files be correct in outputting the content like this?
Thanks. | > Would my index and page files be correct in outputting the content like this?
No. If you attempt to search, or browse posts by tag or category, then you won't see any posts because your index.php file doesn't loop through any posts, according to your description.
_All_ templates in the template hierarchy should use the standard loop because WordPress will query the correct posts and then use the appropriate template to display them. As you can see from the template hierarchy diagram, there are several post archives that will use your theme's index.php template, so it's important for that template to include the loop. The only exception is the 404.php template, which will not need to display any posts (since none have been found).
Since you have single.php and page.php templates in your theme, your index.php file only needs to be optimised for displaying lists of multiple posts, for things like date and category archives, and search results. | stackexchange-wordpress | {

Cache WP remote_get HTTP Response using Transients

$body = get_transient( 'my_remote_response_value' );

if (200 !== wp_remote_retrieve_response_code($response)) {
return;
}
$body = wp_remote_retrieve_body($response);
set_transient( 'my_remote_response_value', $body, 5*MINUTE_IN_SECONDS );
}
if ('a' === $body) {
echo 'A wins';
} else {
// Do something else.
}
}
add_action('init', 'display_api_response');
At first, the transient doesn't exist, so we send a request and save the `$body` as a transient value. Next time, if the transient exists, we skip sending request.

What are the meta fields for an attachment?
I'm trying to find all the meta fields that are used for an attachment: like Title, alternative text, description and caption . I've looked all over and the only one I was able to find was for an Alternative text, which is `_wp_attachment_image_alt`. | You can easily inspect all the metadata for any post like so:
// 123 is the (attachment) post ID
var_dump( get_post_meta( 123 ) );
And in a default WordPress setup with no plugins or theme which add custom metadata to the image attachment post, the metadata you'd get are:
* `_wp_attached_file` — string, the image file (path and name) for the attachment post
* `_wp_attachment_metadata` — array (serialized), the sizes for the image like 'thumbnail' (including original size), and metadata from EXIF/IPTC info.
* `_wp_attachment_image_alt` — string, the image's alternative text
As for the other details like the image title, they are in the post data (in the posts database table), so you can for example use `wp_update_post()` to update these details:
* `post_title` — image title
* `post_excerpt` — image caption
* `post_content` — image description | stackexchange-wordpress | {

Custom Gutenberg-Block esnext pass variables
I am trying to create a Block with @wordpress/create-block, for this you have to use exnext. I`m not pretty good with JS at the moment, still learning.

<div>
<p>
Text
</p>
</div>
)
}
The className is available in the Edit function `export default function Edit({className}) { ... }`, but I cannot get `props` variable. | The problem in your "edit" file is that your `Edit()` function in there is _unpacking/destructuring_ the props, hence `props` is no longer defined or what you expected it to be.

console.log( props.className, props );
}
// .. Or when unpacking the props object:
// Assuming your block got an attribute named myAttribute.
function Edit( { attributes, setAttributes, className } ) {
console.log( className, attributes.myAttribute );

Vimeo froogaloop
Very much a newbie here, but I'm trying to use this idea to disable forward seeking in Vimeo clips embedded on a Wordpress site
To my functions.php I've added
function frogaloop_scripts() {
wp_register_script('snippet', '
wp_register_script('frogaloop','
}
add_action( 'wp_enqueue_scripts', 'frogaloop_scripts' );
On a page with an embedded video, I've got
<iframe id="video1" src=" width="630" height="354" frameborder="0" webkitallowfullscreen="" mozallowfullscreen="" allowfullscreen=""></iframe>
Where 'video1' matches the iframe label in the codepen example.
When I load the page source, I can't even see frogaloop being listed, so I'm not sure the enqueuing is even happening...
Where am I going wrong with this ? | > so I'm not sure the enqueuing is even happening
No, it's not, because you only registered the scripts, but never enqueued them — which should be done using `wp_enqueue_script()`.
Also, you should make `frogaloop` as a dependency for your `snippet.js` script. Hence, register the `frogaloop` script before your `snippet.js` script.
// Register the scripts.
wp_register_script( 'frogaloop', ' array(), null );
// The third parameter is the script dependencies.
wp_register_script( 'snippet', get_template_directory_uri() . '/js/snippet.js', array( 'frogaloop' ) );
// Then enqueue them. But you just need to call:
wp_enqueue_script( 'snippet' );
// because frogaloop will also be enqueued because it's a dependency for your
// snippet.js script.
Now that should work. | stackexchange-wordpress | {

How to display all posts not in a post_format
Using WP_Query() I want to display all posts -except- those with the 'image' post_format. I tried this, but it did not work.

'relation' => 'NOT',

array(
'taxonomy' => 'post_format',
'field' => 'slug',
'terms' => array('post-format-' . $post_format),
)
),
'paged' => get_query_var('paged')
);
query_posts( $args ); | It didn't work because your tax query is missing the operator which should be set to `NOT IN`. So just add it like so:

'terms' => array( 'post-format-' . $post_format ),
'operator' => 'NOT IN',

Whitespace between product image and gallery on initial load of lightbox product page
I'm trying to understand why whitespace appears between the main product image and the product gallery on this page: <
Clicking on the middle image will remove the whitespace.
Why would it be doing this?
Cheers | Ok, so eventually managed to figure out that it was due to a couple of optimization plugins that were interfering with WooCommerce's image slider: JetPack's lazy loading and SG Optimizer.
Deactivated SG Optimizer and added the following to my child theme's functions.php:
function is_lazyload_activated()
{
$condition = is_product();
if ($condition) {
return false;
}
return true;
}
add_filter('lazyload_is_enabled', 'is_lazyload_activated');

Non-existent page returns code 200
I have a page like mysite.com/contacts/ If I enter non-existent urls like:
mysite.com/contacts--/
mysite.com/contacts%20/
i get status 200 and the page opens mysite.com/contacts/ although if I enter:
mysite.com/contacts1/
As expected, I am getting a 404 error.
How can I implement error handling at the CMS level so that non-existent pages return a page with a 404 error template? There may be some plugin that implements URL management? | **That's not what's happening** , when you visit `/contacts--/` it doesn't return a 200 code, but instead it returns a `301` redirect code. The browser then follows this redirect and heads to `/contact` and it's `/contact` that returns `200` code.
This is because `/contact` is the canonical URL of that page, and WordPress redirects to canonical pages out of the box for improved SEO. It should also be adding a meta tag to the header containing the canonical URL to avoid duplicate content penalties. | stackexchange-wordpress | {

What structure should post_content have in the database?
Let me start off by saying that I have no WordPress experience at all so I may be asking a really stupid question. What I need to do is transfer a bunch of articles from a old MySQL database to a WordPress site.
Now I found wp_insert_post and I can get all the data from the old DB. The problem starts with the article images. In the WordPress DB there seems to be a `<figure class="wp-block-image size-large"><img src="hard path to image here" alt="" class="wp-image-4066"/></figure>` tag that points to the exact image. Problem is that it is surrounded by, what I would call strange comments, that look like this :
<!-- wp:image {"id":4066,"sizeSlug":"large"} -->
<!-- /wp:image -->
This id seems to be the ID of the image that is made a attachment type post in the same table. My question is are these comments necessary or can I just generate the tag ? | Those comments have been added by the Gutenberg block editor.

How do you find a file in the media library using the file URL?
We have about 2000 files in our media library and we are working on an audit to organize the files and create a name hierarchy.
But until that is done, I am trying to locate a handful of specific files to replace. I don't know what the files are named in Wordpress, I only have the URL to download the file.
Is there a way to search for the file in the dashboard using the URL? | Based on my research, you would need to run a query on directly on the database using WPDB. So you would do something like this:
Add this in your `functions.php` file:
// retrieves the attachment ID from the file URL
function get_image_id($image_url) {
global $wpdb;
$the_attachment = $wpdb->get_col($wpdb->prepare("SELECT ID FROM $wpdb->posts WHERE guid='%s';", $image_url ));
return $the_attachment[0];
}
And then you can apply it wherever you like this way:
$attachment_url = '
$attachment_id = get_image_id($image_url);
`$attachment_id` will have the attachment ID so you can do whatever you want with it. | stackexchange-wordpress | {

If you want to include extra CSS on your login page then you should hook login_enqueue_scripts and write out an extra `<style>` tag there, or include another CSS file (or even your theme's full CSS file if you want to).

Updating an imported child theme from the wp-admin UI
I have full access to the wp-admin area of a remote WordPress site. I would prefer to work in this UI the whole time and not use FTP.
I have successfully imported my custom child theme for an existing parent theme, from within the wp-admin area.
My question - From the wp-admin area, can I simply re-upload the same child theme zip package every time I have new changes that needs to be applied to it? Is this a suitable practice? Or will this cause issues? | Uploading a new zip package should work the same way as updating themes or plugins.
Please not however that it will only add new files and overwrite existing ones. If you upload a new package without some files (eg. unnecessary CSS or JS), these files will remain on server.

Featured Story Shortcode not outputting content
So I'm trying to get a shortcode working where it calls the posts in the featured story category but I'm having issue getting it to output even just the title from the post. There's no error on the page. But there's nothing else showing either but white space between the nav and footer.

How to fix get_the_category function returning incorrect slug?
So, I'm having an issue where using the get_the_category function is returning an incorrect slug. My code snippet is as so:
<?php $category_detail=get_the_category($post->ID);
foreach($category_detail as $cd){?>
<li class="list-inline-item"><a href="<?php echo $cd->slug ?>"><?php echo $cd->cat_name; ?></a>
</li><?php }
The issue is that the category slug doesn't reflect my site's permalink settings, and returns: `"mysite.com/category-name"` and not `"mysite.com/category/category-name".` I am not sure why the category permalink is being truncated, as the category pages work correctly, but this function is outputting them incorrectly, The slug in question here is for regular posts. | The problem, as I could see it, is not with the `get_the_category()` function. Instead, it's the way you output the category archive link: `href="<?php echo $cd->slug ?>"` — you should instead use `get_category_link()` to get the correct URL of the category archive page. Example:
<a href="<?php echo esc_url( get_category_link( $cd ) ); ?>"> | stackexchange-wordpress | {

Could not insert attachment into the database.
When ever I try to upload new images from WordPress media it shows me above error.
Please help me why wp database shows this error. | Try the following solutins:
1. First of all check your WP database size and check whether the size is full according to your hosting provider's requirement/rule.
2. Second option, add this line into your **wp-config.php** :
define('WP_MEMORY_LIMIT', '256M');
Also if you have access to **php.ini** (or php[version number].ini) file on your server, try to add this line:
memory_limit 512M
3. By default, some database configs have a collation or charset that doesn't allow special character. Check whether the file name of the image you're trying to upload is having any special characters. If so, delete them and use only alphanumeric. Then retry.

how to retrieve the image title for image Post Format
Hope everyone is having a good day. in WordPress Codex Post Format the image post format is defined as
> **image** – A single image. The first tag in the post could be considered the image. Alternatively, if the post consists only of a URL, that will be the image URL and the title of the post (post_title) will be the title attribute for the image.
Now i need to know about what title attribute they are talking about in the above definition of image post format and how to retrieve that title through php as all the data is coming from the_content() function, anyone has any idea? i have researched online and there is literally no issue about this one. | So first off, I hope you're aware that the quote there is a _guideline_ on how should a post of the `image` format be displayed to the user, and the thing about the title attribute applies only to posts where the format is `image` and that the post content is the image URL only, e.g. `
> what title attribute they are talking about
It's the `title` attribute of the `<img>` tag, and the attribute value should be set to the post title.
> how to retrieve that title through PHP
There are some functions you can choose from such as `get_post_field()`, `get_the_title()` and `the_title_attribute()`.
So for example, your `<img>` can be generated like so:
<img src="<?php echo esc_url( get_post_field( 'post_content' ) ); ?>"
title="<?php the_title_attribute(); ?>"> | stackexchange-wordpress | {

How to make a list of companies' information and display them to user, using custom post types and a custom taxonomy?
I need to add a list of companies' information to my website and I want to display the list in a page. Then by clicking on each company, user can see more information about that company in its individual post.
What is the right approach for doing this? I researched about custom post types and custom fields. But they seem to be not right for me. Do I have to build a post for each company? They are more than a hundred. Is there a more speedy way to do this?
P.S The companies has identical fields. Each company has a name, description, etc and also has a few photos. | Custom post types and taxonomies are the appropriate method of doing this. It sounds like you've already identified the appropriate taxonomies and CPT:

Custom Page out of Wp Theme
i have this website running in WP and I had to create a feature to generate pages automatically and I did it through a separate WP backend, which creates the .php pages within the root of the site.
When I call **domain/slug-of-page.php** everything is ok.
But when I call the page without the extension (.php) the WP understands that it is an invalid url (404 error) because there is no page in the WP with that name.
I tried to insert the page created in the `wp_posts` table but when calling the page it loads the WP theme ... I don't want it to load the theme.
Is there a way to make the url friendly (without the extension) and not handled by the WP handler?

Performance of several get_option() calls
I am currently working on my first WordPress plugin. To save and output certain settings I use the native Settings API. Now the question arises, how performant are several calls of the get_option() function.
Since I work object-oriented I use a function which returns the options:
private function get_settings() {
$styles = get_option("style_settings");
return $styles;
}
Every time I need one or more values from the options array, I now call this function. Is it better to assign the options in the constructor to a variable or does it not matter for the performance? | If you check the implementation of `get_option()` you'll see that in line 168 it calls `wp_cache_get()` like so:
$value = wp_cache_get( $option, 'options' );
This means multiple calls to `get_option("style_settings")` within the same PHP execution will be served from cache. There is no need to re-invent this, as you might break other functionality with it. (There are various filters and hooks in the `get_option()` call with which plugins may interfere with this.

Some WordPress Posts are automatically becoming comments on other Posts
This seems like a weird issue. I have published multiple posts on one of my websites. Sometimes, another post on my website (Post C) appears as comment under some other post (Post A).

However this returns the first item in the `$countries` array, instead of the term that is assigned to the current post. | You should no longer use the _legacy_ function parameter format. Instead, as the documentation says, use the `get_terms( $args )` format:

And as for getting only the terms assigned to the current or a specific post, you can either use the `object_ids` parameter with `get_terms()`, or simply use `get_the_terms()`.
So for examples:
$post_id = get_the_ID();
$countries = get_terms( array(
'taxonomy' => 'country',
'object_ids' => $post_id, // set the object_ids

Nav Menu: Theme Location not working
Why do my created Menus on the WordPress Admin dashboard appear in `customtemplate.php` DESPITE not defining it the correct `'theme_location'`?
It will show in that location EVEN if the created menu in the WordPress Admin dashboard is not set to show in any location.
It only hides if the following if check is tested. Why?
if(has_nav_menu('menu-ID1'))
**Functions.php**
register_nav_menus(
array(
'menu-ID1' => __( 'MenuName', 'blabla' ),
)
);
**customtemplate.php**
//Still displays even though the registered menu-ID1 is not used
wp_nav_menu(['theme_location' => 'randomname']); | I'm guessing your menu contains only Pages (posts of the `page` type) on your site?
But nonetheless, with `wp_nav_menu()`, if you specify a `theme_location` that doesn't exist or contains no menu (i.e. no menus assigned to that location), then the `fallback_cb` arg (which defaults to `wp_page_menu()`) will determine what is displayed.
So if you want the function to display the menu only if it's assigned to the specified theme location, you can do the `has_nav_menu()` check:
if ( has_nav_menu( 'menu-ID1' ) ) {
wp_nav_menu( 'theme_location=menu-ID1' );
}
or set the `fallback_cb` to an empty string:
wp_nav_menu( array(
'theme_location' => 'menu-ID1',
'fallback_cb' => '',
) );
// or you may pass the function args as a query string:
wp_nav_menu( 'theme_location=menu-ID1&fallback_cb=' ); | stackexchange-wordpress | {

Adding author option to [products] woocommerce shortcode

Which HTTP headers to use for subdomain <iframe> embedding?
I have a Wordpress site hosted on LightSail (which uses bitnami). The domain is ` On a subdomain ` I have another server running. On this server, I want to embed a page from the main domain ` Currently, I am getting errors that permission is denied.
I have updated the htaccess file like so:
Header set X-Frame-Options "ALLOW-FROM
Header set Content-Security-Policy "frame-ancestors 'self' https: *.example.com"
Header set Referrer-Policy "strict-origin-when-cross-origin"
But the headers don't seem to updating or allowing any iframe embeds. I'm not very well-versed on HTTP Headers so apologies if this is a rather silly question.
Thanks! | I was able to figure out that because Lightsail uses a Bitnami deployment of Wordpress, Bitnami overrides the `.htaccess` file.
Instead you have to update the `/opt/bitnami/apache2/conf/httpd.conf` file by adding the following content:

<IfVersion >= 2.4.7 >
Header always setifempty X-Frame-Options ALLOW-FROM
</IfVersion>
<IfVersion < 2.4.7 >
Header always merge X-Frame-Options ALLOW-FROM

Sanitizing file & directory form input
I'm looking to sanitize admin form input for update_option. The input is for a directory path and file name. The input will look like this:
/directory/subdirectory/
and
/thisfile.min.js
So far, every sanitize I've tried strips out the forward slashes. Any suggestions? | The function that you would want to use is `sanitize_text_field()` which among other things, strips all HTML tags, and remove line breaks, tabs and extra white space.

// And so does this one - I got /thisfile.min.js

// Even with an actual form input (e.g. <input name="my_field">),
// the function worked just fine (using the same data as above).

Create an if is_page statement based on parent page
I am trying to show something in a template based on what page is showing. This is working fine until I want to show a part of the template based on whether the parent post page slug is 'courses'.
So the page url ends in '.com/courses/course-1' so I want specific code to show for all posts where the post parent slug is 'courses'

$post_data = get_post($post->post_parent);
<?php if ( is_page( array( 'learn', 'profile') ) || ($post_data->post_parent == 'courses') ) { ?>
THINGS GO HERE

HTML comment cause issue in functions.php script root

after clearing an html comment that was in the root of script,issue solved. i need to know whats wrong with having HTML comment in functions.php root ?
(BTW my wp site is hosted on a cpanel shared host) | The `functions.php` is loaded before WordPress has sent the HTTP response headers. If you have raw HTML content in that file, even a HTML comment, then that will be sent immediately, triggering PHP's built-in HTTP headers.
Now, WordPress doesn't know about this and tries to send the headers as usual. And that will cause an error message like "Headers already sent …". This message comes with information about the file and line that created the first output, so it's rather easy to debug.
Long story short: Don't create raw output in the `functions.php`, use template files for that. | stackexchange-wordpress | {

if( $load_team_contact && isset( $request['pagename'] ) && 'contact' == $request['pagename'] ){
