我对发生了什么事情很有头脑。我不知道如何解决这个问题。由于我要求paypal包含订单项，因此它会计算总订单项，但它们与总计项不匹配。PayPal网关已拒绝请求。购物车项目金额的总计与订单金额不匹配。 Magento

config.xml中

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

       $this->set = 1; 
      } 
     } 
     return $this; 
    } 
}

我所做的一切，该教程告诉我，我尝试更新基本综合，总计，小计，应有尽有。它仍然没有正确匹配

我是做错了什么？

还有其他帖子，但他们不清楚。很明显，行项目计算的总数不正确。。

找出它并且在线参考是错误的。

在你的配置XML

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

变化之前，和值在标签内应该是“grand_total”

<after>grand_total</after>

如果你之前或大部切除术后放置它，你的折扣将不采取因为总计是最后计算的，所以总计的通知。

因此，您的代码可能会计算小计，但不会计算可能给paypal带来不准确估计的总计
