如何在Yii 2中的GridView小部件中对自定义列进行排序？

Question

I have a custom column in GridView. Actually it's model attribute but I needed to customize it for presenting data in more convenience way. How to add an ability to sort this column?

<?= GridView::widget([
    'dataProvider' => $dataProvider,
    'filterPosition'=>  GridView::FILTER_POS_HEADER,
    'columns' => [
        ['class' => 'yii\grid\SerialColumn'],

        'id',
        'username',
        'about:ntext',
         'birthdate',
        ['attribute'=>'sex',
         'header'=>'Sex',
         'content'=>  function($model){
          return $model->sex==0?'female':'male';  
         },
         'label'=>'Sex',
         'enableSorting'=>TRUE       

        ],

         'email:email',

        ['class' => 'yii\grid\ActionColumn'],
    ],
]); ?>

Answer 1

您丢失了排序链接，因为您在列配置中明确设置了'header'=>'Sex' ，将其删除并显示排序链接。

Answer 2

I'll assume you're using ActiveDataProvider .

Even when you use a custom function to display the attribute, the sorting is done on the actual attribute that is stored in the DB.

Try generating a set of CRUD pages using gii . If you did everything right, your index.php file in views will contain an array of columns. Then you can configure your column like so:

        [
            'attribute' => 'myAttribute',
            'value' => function ($data) {
                return 'example'.' '.$data->myAttribute;
            }
        ],

Obviously, the function needs to do whatever transformations you need. But the sorting will be done on the actual data stored in the DB.

For searching sex it's easy you can set filter. Like

   [
    'attribute'=> 'sex',
    # if you didn't set attribute in model or want different text use label
   'label' => 'Sex of person',
    # if you create it threw ModelSearch and there is attribute/field in one table gii will add automatically andFilterWhere method.
    'filter' => ['0' => 'Female', '1' => 'Male'],
   ],

For more complicated search/sort here is very good documentation related link to tutorial
