PayPal网关拒绝了请求。购物车项目金额的总数与订单金额不匹配。 Magento的

Question

我很清楚最新情况。我不知道如何解决它。由于我要求paypal包含订单项，因此它会计算总订单项，但它们与总计不匹配。

的config.xml

    <sales>
        <quote>
            <totals>
                <biddiscount>
                    <class>winints/biddiscount</class>
                    <before>subtotal</before>
                </biddiscount>
                <globaldiscount>
                    <class>winints/globaldiscount</class>
                    <before>subtotal</before>
                </globaldiscount>
            </totals>
        </quote>
    </sales>

我已经完成了教程告诉我的所有内容，我尝试更新基本总数，总计，小计，一切。它仍然无法正确匹配

我做错了什么？

还有其他帖子，但不清楚。显然，订单项从总计中计算错误。

想出来，是的，在线参考不正确。

在你的配置xml

中

            <globaldiscount>
                <class>winints/globaldiscount</class>
                <before>subtotal</before>
            </globaldiscount>

更改标签之前的to和值应为＆＃34; grand_total＆＃34;

<after>grand_total</after>

如果您在小计之前或之后放置，您的折扣将不会注意总计，因为总计是最后计算的。

因此，您的代码可能会计算小计但不会计算总计，这可能会给paypal一个不准确的估算值
