Reply To: Search for media and exclude search from media in custom post type

No problem, I too have long workdays, at the end I usually make a lot of mistakes.

You can of course limit the code to a specific search ID:

add_filter('asp_results', 'asp_remove_attachments_where_post_type', 10, 2);
function asp_remove_attachments_where_post_type( $results, $search_id ) {
	
	if ( $search_id == 1 ) {
		$excluded = array(
			'post_type_name1',
			'post_type_name2',
		);

		foreach ( $results as $k => $r ) {
			if ( isset($r->post_type) && $r->post_type == 'attachment' ) {
				$parent_id = wp_get_post_parent_id($r->id);
				if ( $parent_id != 0 ) {
					if ( in_array(get_post_type($parent_id), $excluded) ) {
						unset($results[$k]);
					}
				}
			}
		}
	}
	
	return $results;
}

I hope this works 🙂
