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。我到目前为止的进展
mainWindow.loadFile('teacher.html')
有人可以帮助完成此操作吗?还是至少指向正确的方向?

当订户用户角色仅在结帐页面上选择了定向付款方式时,以下代码将向购物车提供2%的折扣:
// 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
}
此代码位于您的活动子主题(或活动主题)的function.php文件中。经过测试并可以正常工作。
要获取正确的所需付款方式ID ,您必须检查使用浏览器检查工具搜索的付款方式单选按钮周围的html代码:
