Woocommerce中基于用户角色和付款方式的折扣百分比 [英] Percentage discount based on user role and payment method in Woocommerce

问题描述

我正在尝试为functions.php创建一个代码段，当同时选择了角色 subscriber和付款方式 credit-card时，将为购物车总额带来2％的折扣。到目前为止我的进步

I was trying to make a code snippet for functions.php which would apply a discount of 2 % for cart totals when the role "subscriber" and the payment method "credit-card" are both selected. My progress so far

function discount_when_role_and_payment(/* magic */) {
global $woocommerce;
if ( /* credit-card selected */ && current_user_can('subscriber') ) {
    /* get woocommerce cart totals, apply 2% discount and return*/
} 
return /*cart totals after discount*/;
}

add_filter( '/* magic */', 'discount_when_role_and_payment' );

有人可以帮助完成此操作吗？还是至少指向正确的方向？

Could anyone help complete this? Or atleast point to the right direction?

推荐答案

以下代码将在有针对性的付款方式下向购物车提供2％的折扣只能由用户用户在结帐页面上选择：

The following code will apply a discount of 2% to cart when a targeted payment method has been selected by a subscriber user role only on checkout page:

// Applying conditionally a discount
add_action( 'woocommerce_cart_calculate_fees', 'discount_based_on_user_role_and_payment', 20, 1 );
function discount_based_on_user_role_and_payment( $cart ) {
    if ( is_admin() && ! defined( 'DOING_AJAX' ) )
        return; // Exit

    // Only on checkout page for 'subscriber' user role
    if ( ! ( is_checkout() && current_user_can('subscriber') ) )
        return; // Exit

    // HERE Below define in the array your targeted payment methods IDs
    $targeted_payment_methods = array( 'paypal', 'stripe' );
    // HERE define the percentage discount
    $percentage = 2;

    if( in_array( WC()->session->get('chosen_payment_method'), $targeted_payment_methods ) ){
        // Calculation
        $discount = $cart->get_subtotal() * $percentage / 100;
        // Applying discount
        $cart->add_fee( sprintf( __("Discount (%s)", "woocommerce"), $percentage . '%'), -$discount, true );
    }
}

// Refreshing totals on choseen payment method change event
add_action( 'woocommerce_review_order_before_payment', 'refresh_payment_methods' );
function refresh_payment_methods(){
    // Only on checkout page
    if ( ! ( is_checkout() && current_user_can('subscriber') ) ) return;
    // jQuery code
    ?>
    <script type="text/javascript">
        (function($){
            $( 'form.checkout' ).on( 'change', 'input[name^="payment_method"]', function() {
                $('body').trigger('update_checkout');
            });
        })(jQuery);
    </script>
    <?php
}

此代码在活动孩子的function.php文件中显示主题（或活动主题）。经过测试并可以正常工作。

This code goes on function.php file of your active child theme (or active theme). tested and works.

所需的付款方式ID ，您将必须使用浏览器检查器工具检查围绕付款方式单选按钮的html代码：

To get the correct desired Payment methods IDs, you will have to inspect the html code around the payment methods radio buttons searching with your browser inspector tools:
