这几天我一直在为这个问题苦苦挣扎。我继承了一个建立在 Magento 上的网站。这个网站销售的产品都可以定制，每个产品都是按订单生产的。当客户想要将特定徽标添加到产品中，然后选择他们想要缝合徽标的线色时，就会出现我的问题。最多有 15 个徽标可用，每个徽标都有自己的一组可用线色。假设客户选择了 logo #6，然后从 logo #6 的可用颜色中选择一个线程并将其添加到购物车。当项目被引用时，它会在购物车中显示“线程颜色 6”以获取线程选项。这很好，订单处理正确。但是，当您在管理员端查看订单时，它将显示所有线色选项，包括他们选择的线色选项。
线色 1：无线
线色 2：无线
线色 3：无线
线色 4：无线
线色 5：线色名称
线色 6：无线

如上所述，订单处理正确在查看订单时让客户服务部门感到困惑。

所以我试图做的是找到设置了值的线色，然后将它的标签更改为像“线色”这样的通用标签，然后从报价中动态删除所有其他线色选项。我在这里找到了一个可能的解决方案，并且 Vinai 在解释代码方面做得很好。我已经尝试过了，甚至逐行逐行执行，我知道它正在根据需要添加和删除选项。但是，当我在调试后删除任何 die() 语句时，会出现 SQL 错误。下面是我的配置、观察者和 SQL 错误。
