如何在WooCommerce 3中添加自定义工作运输方法

Question

我已经成功创建了一种新的运输方式,并为其提供了对运输区域的支持.但是,当我从下拉列表中选择方法将其添加到区域时,它不会出现在"选定的方法列表"中.

我录制了一个截屏gif来演示:

我不能为我的生活弄清楚为什么它不起作用.如果我选择其中一种标准方法(Screencast GIF),它可以正常工作

任何人都知道这里发生了什么以及如何让它发挥作用？

这是我在这个官方帖子中提供的代码: Shipping Method API:

if ( in_array( 'woocommerce/woocommerce.php', apply_filters( 'active_plugins', get_option( 'active_plugins' ) ) ) ) {

    function request_a_shipping_quote_init() {
        if ( ! class_exists( 'WC_Request_Shipping_Quote_Method' ) ) {
            class WC_Request_Shipping_Quote_Method extends WC_Shipping_Method {
                /**
                 * Constructor for your shipping class
                 *
                 * @access public
                 * @return void
                 */
                public function __construct() {
                    $this->id                 = 'request_a_shipping_quote'; // Id for your shipping method. Should be uunique.
                    $this->method_title       = __( 'Request a Shipping Quote' );  // Title shown in admin
                    $this->method_description = __( 'Shipping method to be used where the exact shipping amount needs to be quoted' ); // Description shown in admin

                    $this->title = "Request a Shipping Quote"; // This can be added as an setting but for this example its forced.

                    $this->supports = array(
                        'shipping-zones'
                    );

                    $this->init();

                    $this->init_settings(); // This is part of the settings API. Loads settings you previously init.

                    // Save settings in admin if you have any defined
                    add_action( 'woocommerce_update_options_shipping_' . $this->id, array( $this, 'process_admin_options' ) );

Answer 1

在我尝试使用有问题的代码并修复我在这些帖子的评论中发现的所有错误后，我仍然遇到了一些问题。例如，即使我成功将其添加到运输区域后，我也无法编辑运输方式。

最后，在编辑标准的免费送货 woocoommerce 方法后，我得到了对我有用的代码。希望它会为某人节省时间。

function request_a_shipping_quote_init() {
    if ( ! class_exists( 'Imp_WC_Shipping_Local_Pickup' ) ) {

        class Imp_WC_Pickup_Shipping_Method extends WC_Shipping_Method {

            public function __construct( $instance_id = 0 ) {
                $this->id           = 'imp_pickup_shipping_method';
                $this->instance_id  = absint( $instance_id );
                $this->method_title = __( "????????? ?? ????? ?????? ( MO ?. ??????????? )", 'imp' );
                $this->supports     = array(
                    'shipping-zones',
                    'instance-settings',
                    'instance-settings-modal',
                );
                $this->init();
            }

            public function calculate_shipping( $package = array() ) {
                $this->add_rate( array(

    return $methods;
}
add_filter( 'woocommerce_shipping_methods', 'request_shipping_quote_shipping_method' );

Answer 2

“ woocommerce_shipping_methods”上的方法密钥应与运输方法ID匹配

您的情况：您应该更改

function request_shipping_quote_shipping_method( $methods ) {
    $methods['request_shipping_quote_shipping_method'] = 'WC_Request_Shipping_Quote_Method';

    return $methods;
}

add_filter( 'woocommerce_shipping_methods', 'request_shipping_quote_shipping_method' );

至：

function request_shipping_quote_shipping_method( $methods ) {
    $methods['request_a_shipping_quote'] = 'WC_Request_Shipping_Quote_Method';

    return $methods;
}

add_filter( 'woocommerce_shipping_methods', 'request_shipping_quote_shipping_method' );

改变这一行

public function calculate_shipping( $package ) {

到这条线

public function calculate_shipping($ package = array()){
