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
In case it’s helpful to anyone else, here’s what my code looked like to achieve this. I didn’t end up saving the attachment data at all, per tbuteler’s suggestion, but rather than using $_REQUEST I found I could use the $attachment array directly: function my_attachment_fields_to_edit( $form_fields, $post ) { $supported_exts = supported_types(); // array of … 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’; –> $header_ids Also, with your method, I think that if you call WP_Query with … Read more
Take a look at this http://sltaylor.co.uk/blog/hijacking-the-wordpress-media-library-overlay/
A solution that works for me is to add a clause to the WordPress query when the media library is being displayed. From browsing my WordPress database I noticed that the full path to wp_posts.post_type=”attachment” is stored in the wp_posts.guid column. add_filter(‘posts_where’, ‘limitMediaLibraryItems_56456’, 10, 2 ); function limitMediaLibraryItems_56456($where, &$wp_query) { global $pagenow, $wpdb; // Do … Read more
So far, the only workable solution I’ve come up with is to run a new query within the ajax_query_attachments_args filter. It’s definitely not ideal but works as expected in the absence of a more efficient alternative: function restrict_media_library_by_width($query) { $include = array(); $exclude = array(); $temp_query = new WP_Query($query); if($temp_query->have_posts()) { while($temp_query->have_posts()) { $temp_query->the_post(); $meta … Read more
I had the same issue and did not find any information in my debug output. It worked out, that DOING_AJAX was not defined (I don’t know why). Changing the beginning of async-upload.php from if ( isset( $_REQUEST[‘action’] ) && ‘upload-attachment’ === $_REQUEST[‘action’] ) { define( ‘DOING_AJAX’, true ); } to define( ‘DOING_AJAX’, true ); worked … Read more
I was able to cobble something together. I feel like there is a better approach to solving this, but that it might help to share my progress anyway. The main trick came from this answer by @Vladimir Lukyanov. My main concern with this solution is that the unselect event, “selection:unsingle”, is triggered twice. I was … Read more
WordPress uses the attachment filename to create the attachment post slug. If your file was named something else, there would not be any conflicts. If you have your post permalinks set to /%postname%/ , and you upload an image FIRST, and then create a post SECOND, then WordPress has to make a choice between the … Read more
I found this plugin. It provides a pretty good example of how to integrate the new Media UI with the admin, and is very well documented: https://github.com/thomasgriffin/New-Media-Image-Uploader/ Maybe that can help you.
