Yii2中SqlDataProvider用法示例

$totalCount = Yii::$app->db->createCommand('SELECT COUNT(*) FROM posts WHERE publish=:publish', [':publish' => 1])
      ->queryScalar();
$dataProvider = new SqlDataProvider([
  'sql' => 'SELECT * FROM posts WHERE publish=:publish',
  'params' => [':publish' => 1],
  'totalCount' => $totalCount,
  //'sort' =>false, to remove the table header sorting
  'sort' => [
    'attributes' => [
      'title' => [
        'asc' => ['title' => SORT_ASC],
        'desc' => ['title' => SORT_DESC],
        'default' => SORT_DESC,
        'label' => 'Post Title',
      ],
      'author' => [
        'asc' => ['author' => SORT_ASC],
        'desc' => ['author' => SORT_DESC],
        'default' => SORT_DESC,
        'label' => 'Name',
      ],
      'created_on'
    ],
  ],
  'pagination' => [
    'pageSize' => 10,
  ],
]);
return $dataProvider;

<?= GridView::widget([
    'dataProvider' => $dataProvider,
    'columns' => [
      ['class' => 'yii\grid\SerialColumn'],
      [
        'label' =>"Name",
        'attribute' => 'tbl_column_name',
        'value'=>function($data){
          return $data["tbl_column_name"];
        }
      ],
      'title',
      'author',
      'created_on',
      ['class' => 'yii\grid\ActionColumn'],
    ],
]); ?>
