Snippet: Disable the Gallery Metabox
Important: This can now be done via the Theme Panel.
The following snippet can be used to disable the Gallery metabox completely so it doesn't display in any post type.
/**
* Disable the Gallery Metabox.
*
* @link https://total.wpexplorer.com/docs/snippets/completely-disable-gallery-metabox/
*/
add_filter( 'wpex_gallery_metabox_post_types', '__return_empty_array' );
All PHP snippets should be added via child theme's functions.php file or via a plugin (we recommend WPCode)
