If anybody is interested in do the trick, my solution is this: function remove_media_link( $form_fields, $post ) { unset( $form_fields[‘url’] ); return $form_fields; } add_filter( ‘attachment_fields_to_edit’, ‘remove_media_link’, 10, 2 );
Use get_children I used this code to extract all the images from a page gallery in the chosen order. you can include this code in the loop or use it stand alone. just choose the appropriate post_parent code (see bellow the code example). This example show all images associated to the page id 1, have … Read more
I got curious about the SQL way of finding all posts without any attachments. Method #1 – Sub query with NOT IN Here’s my first attempt to construct such a query: global $wpdb; $sql = ” SELECT p1.ID, p1.post_title FROM {$wpdb->posts} p1 WHERE p1.post_type=”post” AND p1.post_status=”publish” AND p1.ID NOT IN ( SELECT DISTINCT p2.post_parent FROM … Read more
you can do that by running the function set_post_thumbnail( $my_post_id, $thumbnail_id ); remember, you have to process and insert the image into the library first: $uploaddir = wp_upload_dir(); $file = $_FILES[ … whatever you have in your POST data … ]; $uploadfile = $uploaddir[‘path’] . “https://wordpress.stackexchange.com/” . basename( $file ); move_uploaded_file( $file , $uploadfile ); … Read more
Ok, all those hipercomplex functions can be reduced to one simple command: attachment_url_to_postid You only need to parse the image url to retrieve the attachment id: <?php $attachment_id = attachment_url_to_postid( $image_url ); echo $attachment_id; ?> That’s all you need.
WP does not do this by default since there is no guarantee that attachment isn’t still being used by some other post. Basic logic would be to hook into delete_post, query for child attachments and run wp_delete_attachment() on each. I did quick search in plugin repository and came up with tiny plugin that does just … Read more
From the WP-CLI documentation about wp post delete: wp post delete –force $(wp post list –post_type=”attachment” –format=ids) See wp post list for additional information.
I have tested this with an image I created myself with Photoshop where I inserted the word “Süss” in every thinkable IPTC field. I uploaded it to my WordPress 4.6 installation, which has no image handling plugins installed. The uploading went smoothly, the right thumbnails were created in the uploads directory and the caption field … Read more
add_filter( ‘the_content’, ‘attachment_image_link_remove_filter’ ); function attachment_image_link_remove_filter( $content ) { $content = preg_replace( array(‘{<a(.*?)(wp-att|wp-content\/uploads)[^>]*><img}’, ‘{ wp-image-[0-9]*” /></a>}’), array(‘<img’,'” />’), $content ); return $content; } The regex could be simpler and unfortunately this also deprives you of the unique wp-image-xxx (where xxx is the attachment ID) class of the <img> tag, but it’s the safest one I … Read more

[Update] You’ll need to do 2 things Add a rewrite rule (either directly with .htaccess or by using WP_rewrite (Codex reference). The aim here is to deny requests to your documents … Read more
