根据 Woocommerce 中选择的付款方式禁用运输方式

Disable shipping method based on chosen payment method in Woocommerce(根据 Woocommerce 中选择的付款方式禁用运输方式)

问题描述

如果用户选择货到付款"付款，我需要禁用特定的运输方式.问题是以下代码仅在我重置时才有效WooCommerce 每次都会瞬变并刷新.它不适用于来回用户选择.

I need to disable specific shipping method if user selected payment "Cash on Delivery". The problem is that the following code works only if I reset WooCommerce transients each time and refresh. It doesn't work on user selection back and forth.

add_filter( 'woocommerce_package_rates', 'alter_shipping_methods', 100 );
function alter_shipping_methods( $rates ) {

    $chosen_gateway = WC()->session->chosen_payment_method;

    // If payment is Cash on delivery remove specific shipping 
    if($chosen_gateway == 'cod') {

        foreach ( $rates as $rate_id => $rate ) {
           if ( $rate->label === 'Hrvatska pošta' ) {
              unset( $rates[ $rate_id ] );
            }
       }

    }

    return $rates;

}

我确实有这个应该触发的代码，当我点击选项时，我会在控制台中看到输出.

I do have this code which should trigger and I see the output in console when I click around options.

jQuery(document.body).on('change', 'input[name="payment_method"]', function() {
    console.log('Payment method changed');
    jQuery('body').trigger('update_checkout');
});

我试过了，没用

function action_woocommerce_checkout_update_order_review($array, $int) {
    WC()->cart->calculate_shipping();
    return;
}
add_action('woocommerce_checkout_update_order_review', 'action_woocommerce_checkout_update_order_review', 10, 2);

而且我也尝试过调用 PHP 函数的自定义 AJAX 调用，在此过滤器中，没有结果

And I have also tried custom AJAX call which calls a PHP function and inside this filter, no result

add_filter( 'woocommerce_package_rates', 'alter_shipping_methods', 100 );

接下来我应该尝试什么?

What should I try next?

对于 COD 支付网关，您只需在设置中添加统一费率"即可.您要为其启用的运输方式，例如:

For COD payment gateways, you can just add in its settings the "Flat rate" shipping methods that you want to enable for it, like:

对于 Cod 和其他方法或其他支付网关，这里是禁用特定支付网关的特定运输方式的完整工作方式.

For Cod and other methods or for others payment gateways, here is the complete working way to disable a specific shipping method(s) for specific payment gateway(s).

您必须在第一个函数中设置要隐藏的运输方式 ID.

You will have to set in the first function the shipping method Id that you wish to hide.

代码:

add_action( 'woocommerce_package_rates','show_hide_shipping_methods', 10, 2 );
function show_hide_shipping_methods( $rates, $package ) {
    // HERE Define your targeted shipping method ID
    $payment_method        = 'cod';

    $chosen_payment_method = WC()->session->get('chosen_payment_method');

    if( $payment_method == $chosen_payment_method ){
        unset($rates['flat_rate:12']);
    }
    return $rates;
}

add_action( 'woocommerce_review_order_before_payment', 'payment_methods_trigger_update_checkout' );
function payment_methods_trigger_update_checkout(){
    // jQuery code
    ?>
    <script type="text/javascript">
        (function($){
            $( 'form.checkout' ).on( 'change blur', 'input[name^="payment_method"]', function() {
                setTimeout(function(){
                    $(document.body).trigger('update_checkout');
                }, 250 );
            });
        })(jQuery);
    </script>
    <?php
}

add_action( 'woocommerce_checkout_update_order_review', 'refresh_shipping_methods' );
function refresh_shipping_methods( $post_data ){
    // HERE Define your targeted shipping method ID
    $payment_method = 'cod';
    $bool           = true;

    if ( WC()->session->get('chosen_payment_method') === $payment_method )
        $bool = false;

    // Mandatory to make it work with shipping methods
    foreach ( WC()->cart->get_shipping_packages() as $package_key => $package ){
        WC()->session->set( 'shipping_for_package_' . $package_key, $bool );
    }
    WC()->cart->calculate_shipping();
}

代码位于活动子主题(或活动主题)的 function.php 文件中.经测试有效.

Code goes in function.php file of your active child theme (or active theme). Tested and works.

为了能够获得正确的送货方式 ID，您可以使用浏览器检查器，如下所示:

To be able to get the correct shipping method ID you can use your browser inspector, this way:

在测试此代码之前，您可能需要清空购物车.

You may need to empty cart before testing this code.
