在Woocommerce中基于选择的付款方式禁用送货方式 [英] Disable shipping method based on chosen payment method in Woocommerce

问题描述

如果用户选择付款货到付款"，我需要禁用特定的送货方式.问题是以下代码仅在我重置时有效 每次都会刷新WooCommerce并刷新.来回选择用户时不起作用.

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;

}

我确实具有应触发的代码，当我单击选项时，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');
});

我已经尝试过了，但是没用

I have tried with this, it doesn't work

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);

我还尝试了自定义AJAX调用，该调用调用了PHP函数，并且在此过滤器内部，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?

这是使"COD"付款方式禁用特定运输方式的完整工作方式.

Here is the complete working way to make "COD" payment method disable a specific shipping method.

您必须在第一个功能中设置您要隐藏的运输方式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( '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();
}

代码进入您的活动子主题(或活动主题)的function.php文件中.经过测试，可以正常工作.

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

要获取正确的送货方式ID ，您可以使用浏览器检查器，方法是:
