如何在 GridView Yii2 中創建條件

Question

我這里有問題。
我想在GridView添加一個條件

<?= GridView::widget([
    'dataProvider' => $dataProvider,
    'filterModel' => $searchModel,
    'columns' => [
        ['class' => 'yii\grid\SerialColumn'],
        'table_column1',
        'table_column2',
        //CONDITION HERE
        if(condition){
            //BUTTON HERE
        } else {
            //TOOLS COLUMN HERE
        }
    ],
]); ?>

我怎樣才能做到這一點？

Answer 1

如果您只想根據指定條件顯示/隱藏某些列，則可以使用$visible屬性：

<?= GridView::widget([
    'dataProvider' => $dataProvider,
    'filterModel' => $searchModel,
    'columns' => [
        ['class' => 'yii\grid\SerialColumn'],
        'table_column1',
        'table_column2',
        [
            'name' => 'some_column1',
            'visible' => $condition,
        ],
        [
            'name' => 'some_column2',
            'visible' => !$condition,
        ],
    ],
]); ?>

根據$condition ，只有兩列（ some_column1或some_column1 ）中的一列是可見的。

如果您需要兩個 gridview 一個替代另一個的簡單方法是基於備用 $column 內容

if ( condition) {

    $columns  = [
        ['class' => 'yii\grid\SerialColumn'],
        'table_column1',
        'table_column2',
          [
            'attribute'=>'your_att',
            'header'=>'your_header',
            'format'=>'raw',    
            'value' => function($model, $key, $index)
            {   
                    return '<button class="btn green">Y</button>';
            },
        ],
        ],

    } else {
        $columns  = [
        ['class' => 'yii\grid\SerialColumn'],
        'table_column1',
        'table_column2',
         ['class' => 'yii\grid\ActionColumn',
        ],
    }
}

echo GridView::widget([
  'dataProvider' => $dataProvider,
  'filterModel' => $searchModel,
  'columns' => $columns
]); ?>

否則使用原始列類型的值函數，您可以返回每個特定行所需的代碼..

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

        //'id',
        'event_id',
        //'img:ntext',
        //'path:ntext',
        //'type',
        //'description:ntext',
        [
            'attribute' => 'type',
            'value'=> function($data){
                if($data->type == 0){
                    $info = 'Empty';
                }
                if($data->type == 1){
                    $info = 'One';
                }
                if($data->type == 2){
                    $info = 'Two';
                }
                return $info;
            },
            'format'=>'html',
        ],
        
        ['class' => 'yii\grid\ActionColumn'],
    ],
]); ?>
