php - 在 Opencart admin 'Order Info' 页面上添加自定义字段

Question

我想在 opencart 管理订单页面上添加自定义字段。

1. 比较值，例如如果 oc_order.order_id = oc_custom_table.order_id 然后在管理订单列表上显示 oc_custom_table.comment。
2. 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;    }

The controller page is pretty crowded and i have no idea where to add variables so it displays order specific info.

In the language, I just have to define language variables like $_text_custom_variable = 'test'; right? and template files, I just choose a place to display the value.

I am using Opencart 2.0 version.

[EDIT]: Okay so i was able to write a VQMOD by referencing one of the vqmod for it but still cannot pull up data. I get error Trying to get property of non-object

I tried first adding the data in order list.

Answer 1

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。

我在 Admin order 部分进行更改，重要的是要弄清楚更改是在哪种方法中完成的。对于 Model 部分，使用适当的方法并添加查询或编辑当前查询。与 Controller 相同。如果您尝试显示为列表 - order_list(getList()) 或 order_info(getInfo) 部分。对于擅长的人来说这可能很简单，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。
