I am trying to change link to attachment page in wordpress for two days. i am close to resign right now...
What i have right now is:
mysite.com/?attachment_id=1234
What I need is:
mysite.com/{postname}/image/{attachment_id}
I have found something at stack
function __filter_rewrite_rules( $rules )
{
$_rules = array();
foreach ( $rules as $rule => $rewrite )
$_rules[ str_replace( 'attachment', 'media', $rule ) ] = $rewrite;
return $_rules;
}
add_filter( 'rewrite_rules_array', '__filter_rewrite_rules' );
function __filter_attachment_link( $link )
{
return str_replace( 'attachment', 'media', $link );
}
add_filter( 'attachment_link', '__filter_attachment_link' );
But actually it do not change anything. I am not able to enter page with attachment using link:
mysite.com/media_id=123
Please explain me why?

I added the following code to my functions.php file in WordPress 6.1.1 to display excerpts.
function new_excerpt_length($length) {
return 100;
}
add_filter('excerpt_length', 'new_excerpt_length');
function new_excerpt_more($more) {
return '...';
}
add_filter('excerpt_more', 'new_excerpt_more');
...but I also have a use case to show the full excerpt without a read more link.
On page template 1 I add the below code to display the excerpt:
<?php echo the_excerpt(); ?>
...and it displays the excerpt as per the functions.php file but how do I create a 2nd excerpt without the read more link and apply it to page template 2?
Is there a parameter I can use within the_excerpt(parameter); or can I use something like wp_trim_excerpt https://developer.wordpress.org/reference/functions/wp_trim_excerpt/ maybe?
I came across the below code that is supposed to do what I want
function wpex_get_excerpt( $args = array() ) {
// Default arguments.
$defaults = array(
'post' => '',
'length' => 40,
'readmore' => false,
'readmore_text' => esc_html__( 'read more', 'text-domain' ),
'readmore_after' => '',
'custom_excerpts' => true,
'disable_more' => false,
);
// Apply filters to allow child themes mods.
$args = apply_filters( 'wpex_excerpt_defaults', $defaults );
// Parse arguments, takes the function arguments and combines them with the defaults.
$args = wp_parse_args( $args, $defaults );
// Apply filters to allow child themes mods.
$args = apply_filters( 'wpex_excerpt_args', $args );
// Extract arguments to make it easier to use below.
extract( $args );
// Get the current post.
$post = get_post( $post );
// Get the current post id.
$post_id = $post->ID;
// Check for custom excerpts.
if ( $custom_excerpts && has_excerpt( $post_id ) ) {
$output = $post->post_excerpt;
}
// No custom excerpt...so lets generate one.
else {
// Create the readmore link.
$readmore_link = '' . $readmore_text . $readmore_after . '';
// Check for more tag and return content if it exists.
if ( ! $disable_more && strpos( $post->post_content, '<!--more-->' ) ) {
$output = apply_filters( 'the_content', get_the_content( $readmore_text . $readmore_after ) );
}
// No more tag defined so generate excerpt using wp_trim_words.
else {
// Generate an excerpt from the post content.
$output = wp_trim_words( strip_shortcodes( $post->post_content ), $length );
// Add the readmore text to the excerpt if enabled.
if ( $readmore ) {
$output .= apply_filters( 'wpex_readmore_link', $readmore_link );
}
}
}
// Apply filters and return the excerpt.
return apply_filters( 'wpex_excerpt', $output );
}
Output using:
<?php echo wpex_get_excerpt ( $defaults = array(
'length' => 40,
'readmore' => true,
'readmore_text' => esc_html__( 'read more', 'wpex-boutique' ),
'custom_excerpts' => true,
) ); ?>
...but doesn't seem to workas intended. Outputs the excerpt with no link but the args don't see to work when changed. Would be perfect for my use otherwise. Maybe someone sees how to fix this code?
Thanks
So today, all my websites were updated to the new release of WordPress 5.9.1. Good good. However, my custom blocks in Gutenberg that are containing an image element are breaking the style of the media modal (where you can add an image directly in the post).
I started a new project, just to test if it was my theme, or the plugins, but even without any plugin (except ACF Pro) and on the Twenty Twenty-Two theme, if I add my registration code in the functions.php file of 2022 theme, I get the same problem.
Here's the register-block code:
add_action('acf/init', 'my_acf_init_block_types');
function my_acf_init_block_types() {
if( function_exists('acf_register_block_type') ) {
acf_register_block_type(array(
'name' => 'carousel',
'title' => __('Carrousel'),
'description' => __(''),
'render_template' => 'web/blocks/carousel.php',
'category' => 'custom-blocks',
'icon' => 'images-alt',
'keywords' => array( 'carousel', 'carrousel'),
'supports' => array( 'anchor' => true),
));
}
}
And I've created a Field group trying the image with the array annnnnd the one using only the URL.
What I tried:
no plugins (except ACF)
WP theme (2022)
custom theme with no functions
adding the registration code to 2022 theme (same error)
Please, help a sister our here.
I think it was cause by the 5.9.1 update
You can use this in functions.php as temporary fix
function fix_media_views_css() {
echo '<link rel="stylesheet" id="fix-media-views-css" href="'.get_bloginfo('url').'/wp-includes/css/media-views.min.css?ver=5.9.1" media="all">';
}
add_action('admin_footer', 'fix_media_views_css');
I've added that piece of code to my functions.php file (at the end, no biggy).
function acf_filter_rest_api_preload_paths( $preload_paths ) {
if ( ! get_the_ID() ) {
return $preload_paths;
}
$remove_path = '/wp/v2/' . get_post_type() . 's/' . get_the_ID() . '?context=edit';
$v1 = array_filter(
$preload_paths,
function( $url ) use ( $remove_path ) {
return $url !== $remove_path;
}
);
$remove_path = '/wp/v2/' . get_post_type() . 's/' . get_the_ID() . '/autosaves?context=edit';
return array_filter(
$v1,
function( $url ) use ( $remove_path ) {
return $url !== $remove_path;
}
);
}
add_filter( 'block_editor_rest_api_preload_paths', 'acf_filter_rest_api_preload_paths', 10, 1 );
It works perfectly like before. I've tried to downversion it to 5.9 and it worked as well, but it takes more time/effort and many mistakes can happen.
Hope it helps more than one.
ACF is aware of the issue: https://github.com/AdvancedCustomFields/acf/issues/612
Here is the temp fix, paste in your functions.php:
function acf_filter_rest_api_preload_paths( $preload_paths ) {
global $post;
$rest_path = rest_get_route_for_post( $post );
$remove_paths = array(
add_query_arg( 'context', 'edit', $rest_path ),
sprintf( '%s/autosaves?context=edit', $rest_path ),
);
return array_filter(
$preload_paths,
function( $url ) use ( $remove_paths ) {
return ! in_array( $url, $remove_paths, true );
}
);
}
add_filter( 'block_editor_rest_api_preload_paths', 'acf_filter_rest_api_preload_paths', 10, 1 );
I get all my products from an API and those who are variations to each other all share a custom meta key called "api_product_family". The products with the same api_product_family are variants to each other, so on the single page I have a hook where I display the other variants with image and anchor to it's variants.
My code:
function mv_variations() {
global $post;
global $wpdb;
$product_id = $post->ID;
$product_family = get_post_meta( $post->ID, 'api_product_family', true );
if(!empty($product_family)) {
$query = "
SELECT post_id
FROM " . $wpdb->prefix . "postmeta
WHERE meta_value = '" . $product_family . "'
";
$products = $wpdb->get_col($query);
if(count($products) > 0) {
for($i=0; $i<count($products); $i++) {
if($products[$i] == $product_id) {
unset($products[$i]);
}
}
if(count($products) > 0) {
print '<h3>Choose other variants: </h3>';
foreach($products as $product) {
$image = wp_get_attachment_image_src(get_post_thumbnail_id($product));
print '<img src="' . $image[0] . '" alt="img"/> ';
}
}
}
}
}
add_action( 'woocommerce_single_product_summary', 'mv_variations' );
The problem:
I have a LOT of posts, and a lot of post_meta's, so it's taking an eternity to load so I was thinking to move this whole function inside and AJAX call so it's doesn't slow down the initial load. The problem is that I have no idea how to do that with wordpress
Are you simply looking to run a WP function via AJAX?
1) Add ajax actions
This needs to run inside the main plugin file. If you run this only on the public code, it will not work. WP is a little weird and all ajax uses admin-ajax.php
if ( wp_doing_ajax() ){
add_action( 'wp_ajax_yourcustomfunction', array($this, 'yourcustomfunction') );
add_action( 'wp_ajax_nopriv_yourcustomfunction', array($this, 'yourcustomfunction') );
}
function yourcustomfunction(){
echo 'success';
exit();
}
2) In JavaScript
in the backend, you have the global: ajaxurl for the ajax url
BUT in the front end you need to pass this as a variable via wp_localize_script
$datatoBePassed = array(
'ajaxurl' => admin_url( 'admin-ajax.php' ),
);
wp_localize_script( 'your_javascript_script', 'plugin_display_settings', $datatoBePassed );
In JS:
var datavar = {
action: 'yourcustomfunction',
};
$.post(plugin_display_settings.ajaxurl, datavar, function(response){
//response received here. It will be 'success' which is echoed in PHP
});
3)
If you also want to run a security nonce check (to check the request truly originates from the WP website, prevents some attacks), it gets a little more complicated:
$datatoBePassed should also include 'security' => wp_create_nonce( 'yourplugin_security_nonce' ),
datavar in JS includes security: plugin_display_settings.security,
Finally, your PHP custom function begins with:
// Check security nonce.
if ( ! check_ajax_referer( 'yourplugin_security_nonce', 'security' ) ) {
wp_send_json_error( 'Invalid security token sent.' );
wp_die();
}
// If security check passed, run further
So I think you might get better performance using WP_Query. Below I converted what you have into a custom WP_Query. May need some slight adjustment but should be the right direction.
function mv_variations() {
global $post_id;
// get current post "product family"
$product_family = get_post_meta( $post_id, 'api_product_family', true );
// build related "product family" products query
$products_query_args = array(
'post_type' => 'product', // may need to update this for your case
'posts_per_page' => -1, // return all found
'post__not_in' => array($post_id), // exclude current post
'post_status' => 'publish',
// use a meta query to pull only posts with same "product family" as current post
'meta_query' => array(
array(
'key' => 'api_product_family',
'value' => $product_family,
'compare' => '='
)
)
);
$products_query = new WP_Query($products_query);
// use "the loop" to display your products
if ( $products_query->have_posts() ) :
print '<h3>Choose other variants: </h3>';
while ( $products_query->have_posts() ) : $products_query->the_post();
print ''. wp_get_attachment_image() .'';
endwhile;
// restore global post
wp_reset_postdata();
endif;
}
add_action( 'woocommerce_single_product_summary', 'mv_variations' );
I am wondering if you're able to help me with the following WordPress customization. We're using the WP Job Manager plugin (https://wpjobmanager.com/) and I'd need a little help with a slug/permalink edit.
In the documentation is an article available which explains the following: at the current situation links are generated as follows: domain.com/job/job-name. However, I need the following structure: domain.com/job-category/job-name.
Please check: https://wpjobmanager.com/document/tutorial-changing-the-job-slugpermalink/
The article explains this. Please check the code on: Example: Adding the category to the base URL. When I remove the 'job' in the following code, the job listings are working fine, but the rest of my website returns in a 404 error (also after saving the permalinks).
$args['rewrite']['slug'] = 'job/%category%';
To
$args['rewrite']['slug'] = '%category%';
Full code:
function job_listing_post_type_link( $permalink, $post ) {
// Abort if post is not a job
if ( $post->post_type !== 'job_listing' )
return $permalink;
// Abort early if the placeholder rewrite tag isn't in the generated URL
if ( false === strpos( $permalink, '%' ) )
return $permalink;
// Get the custom taxonomy terms in use by this post
$terms = wp_get_post_terms( $post->ID, 'job_listing_category', array( 'orderby' => 'parent', 'order' => 'ASC' ) );
if ( empty( $terms ) ) {
// If no terms are assigned to this post, use a string instead (can't leave the placeholder there)
$job_listing_category = _x( 'uncat', 'slug' );
} else {
// Replace the placeholder rewrite tag with the first term's slug
$first_term = array_shift( $terms );
$job_listing_category = $first_term->slug;
}
$find = array(
'%category%'
);
$replace = array(
$job_listing_category
);
$replace = array_map( 'sanitize_title', $replace );
$permalink = str_replace( $find, $replace, $permalink );
return $permalink;
}
add_filter( 'post_type_link', 'job_listing_post_type_link', 10, 2 );
function change_job_listing_slug( $args ) {
$args['rewrite']['slug'] = 'job/%category%';
return $args;
}
add_filter( 'register_post_type_job_listing', 'change_job_listing_slug' );
Well, I was also stuck in some type of error once. But in my case, I was creating everything my self. So I change the template accordingly.
However, In you case, I think it relates to URL Re-Writing. Please check out the following links. I hope those will help.

What I'm trying to do is change the link to the main attachment page in Wordpress. Basically, I'm trying to change the word attachment to media.
I'm trying to change:
example.com/parent-category/child-category/post-slug/attachment/attachment-name/
to:
example.com/parent-category/child-category/post-slug/media/attachment-name/
Thanks in advance for any help on this.
I know this is an old question, but I just stumbled on it and thought it was worth a shot;
function __filter_rewrite_rules( $rules )
{
$_rules = array();
foreach ( $rules as $rule => $rewrite )
$_rules[ str_replace( 'attachment/', 'media/', $rule ) ] = $rewrite;
return $_rules;
}
add_filter( 'rewrite_rules_array', '__filter_rewrite_rules' );
function __filter_attachment_link( $link )
{
return preg_replace( '#attachment/(.+)$#', 'media/$1', $link );
}
add_filter( 'attachment_link', '__filter_attachment_link' );
