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'],
    ],
]); ?>
