Add additional status to WooCommerce Return and Warranty

I want to use the following add-on supplied by WooCommerce to add more customer statuses to the WooCommerce Return and Warranty plugin. function warranty_add_custom_statuses() { if (! function_exists('warranty_get_statuses')) return; // Statuses to add $statuses = array('Custom Status 1', 'Custom Status 2'); foreach ( $statuses as $status ) { $term = get_term_by( 'name', $status, 'shop_warranty_status' ); if (! $term ) { wp_insert_term( $status, 'shop_warranty_status' ); } } add_action( 'init', 'warranty_add_custom_statuses', 30 );
