Show Post ID in “Find Posts or Pages” box in Media Library?
You cannot do that with pure PHP. The table is created in wp-admin/includes/ajax-actions.php::wp_ajax_find_posts(), and there is no filter.

Give attachments an archive page
This is untested, so apologies there, but I’m thinking out loud, have you tried re-registering the post type afterwards? Or flushed rewrite rules after your initial attempt with flush_rewrite_rules();? function change_attachment_post_type() { $args = get_post_type_object(‘attachment’); $args->has_archive = true; $args->rewrite = [ ‘slug’ => ‘media’ ]; register_post_type($args->name, $args); // As a temporary one time, remove after … Read more
