If you only want to add an extra class, then you should use wp_get_attachment_image. It has few extra params, and the last one is used for setting class names. Sample usage: <?php echo wp_get_attachment_image( get_the_ID(), ‘thumbnail’, “”, [“class” => “my-custom-class”] ); ?> The main advantage of this aproach is that you will also get the … Read more
I have checked your code, and I think you are missing the guid of the images. Please have a look at the code below: $post_id = 1234; $images = array(‘filename1.png’, ‘filename2.png’, … ‘filename10.png’); // Get the path to the upload directory. $wp_upload_dir = wp_upload_dir(); foreach($images as $name) { $attachment = array( ‘guid’=> $wp_upload_dir[‘url’] . “https://wordpress.stackexchange.com/” … Read more
For the first one, you can add ‘exclude’ => get_post_thumbnail_id() as a parameter (as shown here). For the second one, you can add ‘post_mime_type’ => ‘application/pdf’, but I’m not sure that would always work, afaik, pdfs have more than one mime type.
An attachment is a Post The posts table contains information on the attachment post. In WordPress every uploaded media has it’s own post entry, where post_type is ‘attachment’ and post_status is ‘inherit’. In fact, you can get attachment post types using functions used to get other post types, like post, page or any CPT. That … Read more
You can filter default rewrite rules and remove those for attachments: function cleanup_default_rewrite_rules( $rules ) { foreach ( $rules as $regex => $query ) { if ( strpos( $regex, ‘attachment’ ) || strpos( $query, ‘attachment’ ) ) { unset( $rules[ $regex ] ); } } return $rules; } add_filter( ‘rewrite_rules_array’, ‘cleanup_default_rewrite_rules’ ); Don’t forget to … Read more
Turns out I solved my own question with help from a colleague. The two filters that get called after media is uploaded or when media is being edited are; ‘add_attachment’ and ‘edit_attachment’. Here is the code I am using, I then check to see if the attachment is an image (code omitted from example). function … Read more
How about this? It adapts an example on the get_posts() function reference page. function delete_post_media( $post_id ) { $attachments = get_posts( array( ‘post_type’ => ‘attachment’, ‘posts_per_page’ => -1, ‘post_status’ => ‘any’, ‘post_parent’ => $post_id ) ); foreach ( $attachments as $attachment ) { if ( false === wp_delete_attachment( $attachment->ID ) ) { // Log failure … Read more
add_filter( ‘wp_generate_attachment_metadata’, ‘delete_fullsize_image’ ); function delete_fullsize_image( $metadata ) { $upload_dir = wp_upload_dir(); $full_image_path = trailingslashit( $upload_dir[‘basedir’] ) . $metadata[‘file’]; $deleted = unlink( $full_image_path ); return $metadata; }
@s_ha_dum suggests that Post meta will be deleted automatically. Therefore because his reputation suggests he knows what he is talking about, this solution only handles Post attachments. I’d suggest checking out the docs for the before_delete_post() hook, as it’s quite handy to be able to check out what Post Type is being deleted, etc. add_action(‘before_delete_post’, … Read more
Your arguments for both wp_get_attachment_image_url() and wp_get_attachment_image() are in the wrong order – check the linked documentation for details. Additionally, wp_get_attachment_image_url() returns a URL – not an actual image element. Removing the width and height attributes from <img> elements is inadvisable: if the layout of the page is in any way influenced by the size … Read more
