YII2 gridview对两列值的总和进行排序
我成功地在 gridview 中显示了 3 列.attr1、attr2 和 2 个属性的总和.attr1 和 attr2 来自数据库，第三列是它们的总和.如何使排序和过滤工作?
这是网格视图.
<代码> ['标签' =>'查询次数','价值' =>功能($模型){返回 $model->countEnquire + $model->countPhone + $model->countTrial;},'启用排序' =>真的，]如何为该列添加排序?
解决方案好的，我没有你的完整源代码，但可以帮助提供一个基本示例.理想情况下，您应该首先使用
我添加了一些测试数据:
然后我使用 Gii 创建了模型和 CRUD 文件，然后我对其进行了修改以向您展示您希望实现的自定义求和/排序的示例.见下文.

I successfully displayed the 3 columns in the gridview. the attr1, attr2, and the sum of the 2 attributes. attr1 and attr2 are from the database and the 3rd column is their sum. How do I make the sorting and filtering work?
Here is the gridview.
[
'label' => 'Number of Enquiries',
'value' => function ($model) {
return $model->countEnquire + $model->countPhone + $model->countTrial;
},
'enableSorting' => true,
]
How add sorting for this column?
解决方案OK, I don't have your full source code to go by but can help with a basic example. Ideally you should start by creating your model and CRUD files using Gii like I have for in my example below.
Here is my basic database table, record:
I added some test data:
Then I created the model and CRUD files using Gii, which I then modified to show you an example of the custom summing/sorting you wish to achieve. See below.
@app/models/Record.php

class Record extends yiidbActiveRecord
{
public $sum;
public function getSum()
{
$this->sum = 0;
if (is_numeric($this->attr1) && is_numeric($this->attr2)) {
$this->sum = $this->attr1 + $this->attr2;
}
return $this->sum;
