woocommerce - 划分woocommerce运输方式

Question

我正在尝试将 woocommerce 的运输方式划分为如下图所示的类别。我尝试创建一种运输方式，但它不起作用。

到目前为止，这是我的代码。有没有人对此有任何见解？

add_action('woocommerce_shipping_init', 'request_shipping_quote_method');
function request_shipping_quote_method() {

    if ( ! class_exists( 'WC_Request_Shipping_Quote_Method' ) ) {
        class WC_Request_Shipping_Quote_Method extends WC_Shipping_Method {

            public function __construct( $instance_id = 0) {
                $this->id = 'request_shipping_quote';
                $this->instance_id = absint( $instance_id );
                $this->domain = 'rasq';
                $this->method_title = __( 'Title 1', $this->domain );
                $this->method_description = __( 'Shipping method to use as a tittle', $this->domain );
                $this->supports = array(
                    'shipping-zones',
                    'instance-settings',
                    'instance-settings-modal',
                );
                $this->init();
            }

           function init_form_fields() {
                $this->instance_form_fields = array(
                    'title' => array(
                        'type'          => 'text',
                        'title'         => __('Title', $this->domain),
                        'description'   => __( 'Title to be displayed on site.', $this->domain ),
                        'default'       => __( 'Title', $this->domain ),
                    ),
                    );
            }

            public function calculate_shipping( $packages = array() ) {
                $rate = array(
                    'id'       => $this->id,
                    'label'    => $this->title,
                   );
                $this->add_rate( $rate );
            }
        }
    }
}

add_filter('woocommerce_shipping_methods', 'add_request_shipping_quote');
function add_request_shipping_quote( $methods ) {
    $methods['request_shipping_quote'] = 'WC_Request_Shipping_Quote_Method';
    return $methods;
}
