Media Library featured filter

Hi, @beachmat

It is possible to filter the media library in WordPress to display only featured images. To do this, you can use the parse_queryhook in combination with the meta_queryparameter to filter the media library to display only items that are marked as featured images.

Here’s an example of how you could use this hook to filter the media library to display only featured images:

add_action( 'parse_query', 'filter_media_library' );

function filter_media_library( $query ) {
    // Make sure we're in the admin and on the correct screen
    if ( is_admin() && isset( $_GET['post_type'] ) && 'attachment' == $_GET['post_type'] ) {
        // Check if the 'featured_image' query var is set
        if ( isset( $_GET['featured_image'] ) && '1' == $_GET['featured_image'] ) {
            // Set the meta_query to only show items that are marked as featured images
            $query->query_vars['meta_query'] = array(
                array(
                    'key'   => '_thumbnail_id',
                    'value' => '',
                    'compare' => '!='
                )
            );
        }
    }
}

To use this code, you can add it to your theme’sfunctions.php file or create a custom plugin.

Then, to filter the media library to display only featured images, you can add the featured_image=1 query variable to the URL of the media library page. For example: https://yoursite.com/wp-admin/upload.php?featured_image=1

I hope this helps! Let me know if you have any questions.
Thank you.

Thanks, but that code isn’t working for me. When I add the parameter to the URL, it makes no difference to the number of images listed.
