【问题描述】：

我很清楚发生了什么。我不知道如何解决它。由于我要求贝宝包含订单项，它会计算订单项总数，但它们与总计不匹配。

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>

GlobalDiscount 类

我已经完成了教程告诉我的所有事情，我尝试更新基本总计、总计、小计等所有内容。它仍然没有正确匹配

我做错了什么？？

还有其他帖子，但不清楚。显然，行项目从总计中计算不正确。 .

【解决方案1】：

想通了，是的，网上的参考资料不正确。

在你的配置 xml 中

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

将标签中的之前更改为和值应为“grand_total”

<after>grand_total</after>

如果您将其放在小计之前或之后，您的折扣将不会考虑总计，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，这可能会给贝宝提供不准确的估计
