Yii2中SqlDataProvider用法示例

本文实例讲述了Yii2中SqlDataProvider用法。分享给大家供大家参考，具体如下：

第一种方法：

    $totalCount = Yii::$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;

第二种：

    <?= 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'],
        ],
    ]); ?>
