Woocommerce 结帐页面上的额外贝宝费用

问题描述

在 Woocommerce 中，我们试图在通过 Paypal 支付网关购买的订单中增加额外费用.

In Woocommerce, we are trying to add an additional cost to the order when is purchased via Paypal payment gateway.

我们通过这种方式改变了发送到 Paypal 的价格:

We did it changing the price that is sent to Paypal this way:

add_filter('woocommerce_paypal_args', 'addition_pay');

function addition_pay($paypal_args){
        $new_value=$paypal_args['amount_1']+10;
        $paypal_args['amount_1']=$new_value;
        return $paypal_args;
} 

它有效，但问题是在付款过程之后，这笔额外费用不会反映在订单和电子邮件通知中.

It works, but the problem is after the payment process, this additional cost is not reflected in Orders and email notifications.

这可以通过某种方式解决吗?任何帮助表示赞赏.

Is this can be solved in some way? Any help is appreciated.

推荐答案

您最好根据支付网关(此处为您的 Paypal)添加费用，如下所示:

You should better add a fee based on payment gateway (here Paypal for you), like in the following:

// Add a fee of 10.00 when Paypal is chosen
add_action( 'woocommerce_cart_calculate_fees', 'custom_paypal_additional_fee', 20, 1 );
function custom_paypal_additional_fee( $cart ) {
    if ( is_admin() && ! defined( 'DOING_AJAX' ) )
        return;

    if( WC()->session->get( 'chosen_payment_method' ) == 'paypal' )
        $cart->add_fee( __( 'Paypal fee', 'woocommerce' ), 10.00 );
}

// Add the information on checkout paypal text gateways section
add_filter('woocommerce_gateway_icon', 'custom_paypal_gateway_text', 20, 2 );
function custom_paypal_gateway_text( $html, $gateway_id ) {
    if( $gateway_id == 'paypal' )
        $html .= ' <small class="paypal-fee">(+ '.wc_price(10.00).')</small>';

    return $html;
}

// Enable ajax update checkout event when choosing a gateway to refresh the fee
add_action('wp_footer', 'payment_gateways_update_checkout_event' );
function payment_gateways_update_checkout_event() {
    ?>
    <script type="text/javascript">
        (function($){
            $('form.checkout').on( 'change', 'input[name^="payment_method"]', function() {
                var t = { updateTimer: !1,  dirtyInput: !1,
                    reset_update_checkout_timer: function() {
                        clearTimeout(t.updateTimer)
                    },  trigger_update_checkout: function() {
                        t.reset_update_checkout_timer(), t.dirtyInput = !1,
                        $(document.body).trigger("update_checkout")
                    }
                };
                $(document.body).trigger('update_checkout')
            });
        })(jQuery);
    </script>
    <?php
}

代码位于活动子主题(或活动主题)的 function.php 文件中.经过测试和工作.
