I would recommend that you begin by having a look at a question asked more recently here. The best option would be to create a custom plugin so that the WP core doesn’t get affected. Editing core files is never a good idea, plus you would lose any changes when updating WP.
This isn’t 100% complete, but should be a good start for you. <a href=”https://wordpress.stackexchange.com/questions/31371/<?php echo wp_nonce_url(“/wp-admin/post.php?action=delete&post=$post->ID”, ‘delete-attachment_’ . $post->ID ) ?>”><?php _e( ‘Delete Permanently’ ) ?></a> A couple notes on what you’ll have left to do: This will do no confirmation, so you’ll probably want to use JS to verify that it wasn’t clicked by … Read more
function get_attachment_files(){ $args = array( ‘post_type’ => ‘attachment’, ‘numberposts’ => -1, ‘post_status’ => null, ‘post_parent’ => 0 ); $attachments = get_posts($args); if ($attachments) { foreach ($attachments as $post) { setup_postdata($post); wp_delete_post( $post->ID ); } } } add_action(‘admin_init’,’get_attachment_files’); adapted from: http://wpsnipp.com/index.php/functions-php/list-all-unattached-files-in-media-library/ I’d be careful of this though, because I am not sure it won’t delete the … Read more
Good code. I think you could simplify by making direct SQL queries instead: — Featured Images SELECT `meta_value` FROM `wp_postmeta` WHERE `meta_key` = ‘_thumbnail_id’; –> $thumbnail_ids — Header Images SELECT `post_id` FROM `wp_postmeta` WHERE `meta_key` = ‘_wp_attachment_context’ and `meta_value` = ‘custom-header’; –> $header_ids Also, with your method, I think that if you call WP_Query with … Read more
The code below will only run once whenever a file is uploaded. We keep an array ( $image_mimes ) of acceptable image-mimetypes We get the current attachment mime type We make sure what is given is indeed an image ( because we don’t need unnecessary postmeta cluttering our table ) We grab the title from … Read more
I eventually worked this out. After a lot of thinking it dawned on me that attachments are merely posts assigned to the post_type of ‘attachment’ so then I soon discovered that attachments have a post_content field, as well as a post_title field. For my needs, I only needed the post_title attribute as my descriptions are … Read more
I learned from Brian Fegter that you can Un-attach an image from a post while participating in this question: Can I attach an image to a different post? It isn’t exactly “simple”, but not to difficult. It’s the only solution I’ve been able to find.
You can add inputs and fields to attachments by hooking into attachment_fields_to_edit. This will add fields to both the modal as well as the attachment editor. The catch I found is that WordPress (if anyone has experienced differently PLMK) doesn’t save the extra fields data so you have to hook into a couple other items. … Read more
get_the_post_thumbnail attribute array doesn’t know STYLE , the fields that are available for you to use are: src class alt title so just use the class and define you class to it: $attr = array( ‘title’ => get_the_title(), ‘alt’ => get_the_title(), ‘class’ => ‘rss_thumb’ ); $thumb = get_the_post_thumbnail($post->ID, ‘large-thumb’, $attr); and then define the style … Read more
Jose, give this a shot and see if that’s the kind of thing you had in mind.. EDIT: Done a little bit of testing and copying of core code to archieve this, but i think the new example i’ve added below should do what you’ve described, remove the buttons, “Insert into Post”, etc…, but keep … Read more
