This means that you need to get the ID from the On-going category term and then passing that ID to the child_of parameter. To note, the child_of parameter returns all descendants of the term passed, this includes direct … Read more
// remove the delete link for the specific category function category_row_actions( $actions, $tag ) { if ( $tag->term_id == PROTECTED_TERM_ID ) unset( $actions[‘delete’] ); return $actions; } // create the category if not excists (in case it’s removed again in another theme) if (file_exists (ABSPATH.’/wp-admin/includes/taxonomy.php’)) { require_once (ABSPATH.’/wp-admin/includes/taxonomy.php’); if ( ! get_cat_ID( ‘One page’ ) … Read more
