我几天来一直在努力解决这个问题。我继承了一个建立在Magento上的网站。该网站销售的产品可以全部定制，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，然后选择他们希望将徽标拼接的线色时，就会出现问题。最多可提供15个徽标，每个徽标都有自己的可用线色。让我们说客户选择徽标＃6，然后从徽标＃6的可用颜色中选择一个线程并将其添加到购物车中。当引用该项时，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，它将显示所有线程颜色选项，包括他们选择的那个。因此，如果该项目有6个徽标选项，并且他们选择徽标5作为选项，则在管理员方面它显示如下：
螺纹颜色1：无螺纹
螺纹颜色2：无螺纹
螺纹颜色3：无螺纹
螺纹颜色4：无螺纹
螺纹颜色5：螺纹颜色名称
螺纹颜色6：无螺纹
就像我上面说的那样，订单处理正确，在查看订单时，客户服务部门会感到困惑。
所以我试图做的是找到具有值集的线程颜色，然后将其标签更改为类似“线程颜色”的通用颜色，然后动态地从引用中删除所有其他线程颜色选项。我发现了一个possible solution here，Vinai在解释代码方面做得很好。我已经尝试了这一点，甚至逐行介绍，我知道它是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，我得到一个SQL错误。下面是我的配置，观察者和SQL错误。
