我想在 opencart 管理订单页面上添加自定义字段。
- 比较值，如 if
oc_order.order_id = oc_custom_table.order_id然后显示oc_custom_table.comment在管理订单列表上。
- 在管理订单信息页面上显示相同的内容。
我在 admin_model_order.php 页面中添加了一个自定义函数，其中包含所有查询。
public function getCustomTable($order_id) {
$query = $this->db->query("SELECT * FROM " . DB_PREFIX . "custom_table WHERE order_id = '" . (int)$order_id . "'");
return $query->rows;
}
控制器页面非常拥挤，我不知道在哪里添加变量，因此它显示订单特定信息。
在语言中，我只需定义语言变量，例如 $_text_custom_variable = 'test';正确的？和模板文件，我只是选择一个地方来显示值。
我使用的是Opencart 2.0版本。
[编辑]：好的，我可以通过引用其中一个 vqmod 来编写 VQMOD，但仍然无法提取数据。我收到错误Trying to get property of non-object
我尝试首先在订单列表中添加数据。

我自己解决了这个问题。这就是我的理解。我可能错了，但简单的代码有效。
我正在管理订单部分进行更改，重要的是要弄清楚更改是通过哪种方法完成的。对于模型部分，使用适当的方法并添加查询或编辑当前查询。与控制器相同。如果您尝试显示为列表 - order_list(getList()) 或 order_info(getInfo) 部分。对于擅长的人来说可能很简单，但对我来说，这是我的第一次，所以花了很多时间。
下面是 VQMOD 格式的工作代码。
