    }
}

使用此代码我将向产品网格添加新列，其中我显示此产品所在的增量订单ID。

在我们的商店中，一个产品不能出现在一个订单中。

所以这就是它的外观：

一切都很好。当我尝试使用订单增量ID搜索此网格时出现问题。我收到以下错误：

致命错误：在非对象中调用成员函数getBackend（） /var/sentora/hostdata/zadmin/public_html/dev_sportsdirect_bg/app/code/core/Mage/Eav/Model/Entity/Abstract.php 在816行

我的错误在哪里？为什么我的搜索不起作用？我想要的是当我在adminhtml产品网格中输入订单增量ID并启动搜索以显示订单中包含的所有产品以及我正在进行搜索的增量ID。

我希望我已经解释得很好。

期待您的帮助和解答。

亲切的问候。
