如何在Yii2 GridView ActionColumn中访问行号？

Question

我在Yii2中的网格视图的Yii2中有一些自定义按钮。我需要将行号添加到按钮数据中。这是我拥有的..。

GridView::widget([
    'dataProvider' => $dataProvider,
    'columns' => [
        ['class' => 'yii\grid\SerialColumn',
            'contentOptions' => ['style' => 'font-size:20px']],
        ['header' => 'Blue or Red',
            'class' => 'yii\grid\ActionColumn',
            'template' => '{blue} {red}',
            'buttons' => [
                'blue' => function ($url, $model, $key) {
                    return bootstrap\Button::widget([
                        'label' => 'blue',
                        'id' => 'blue' . **ROW-NUMBER**,
                        'options' => [
                            'class' => 'btn-lg btn-dark votebtn',
                            'data-vote' => 1,
                            'data-row' => **ROW-NUMBER**
                        ]
                    ]);
                },
                'red' => function($url, $model, $key) {
                    return bootstrap\Button::widget([
                        'label' => 'red',
                        'id' => 'red' . **ROW-NUMBER**,
                        'options' => [
                            'class' => 'btn-lg btn-dark votebtn',
                            'data-vote' => -1,
                            'data-row' => **ROW-NUMBER**
                        ]
                    ]);
                }
            ],        
        ],
    ],
]);

我需要用什么代替行号来获得每个按钮所在的行？

Answer 1

假设“行号”是一个有效的模型值，例如id。

如果有模式对象，则使用$model->id。

 'buttons' => [
            'blue' => function ($url, $model, $key) {
                return bootstrap\Button::widget([
                    'label' => 'blue',
                    'id' => 'blue' . **ROW-NUMBER**,
                    'options' => [
                        'class' => 'btn-lg btn-dark votebtn',
                        'data-vote' => 1,
                        'data-row' => $model->id
                    ]
                ]);
            },
            'red' => function($url, $model, $key) {
                return bootstrap\Button::widget([
                    'label' => 'red',
                    'id' => 'red' . **ROW-NUMBER**,
                    'options' => [
                        'class' => 'btn-lg btn-dark votebtn',
                        'data-vote' => -1,
                        'data-row' => $model->id
                    ]
                ]);
            }
        ],        

或者使用$model‘if’如果您有一个数组

可以获得行号，如下所示：

'red' => function($url, $model, $key) use ($dataProvider) {
     $pagination = $dataProvider->getPagination();
     if ($pagination !== false) {
         $rowNumber = $pagination->getOffset() + $key + 1;
     } else {
         $rowNumber = $key + 1;
     }
     return bootstrap\Button::widget([
          'label' => 'red',
          'id' => 'red' . $rowNumber,
          'options' => [
          'class' => 'btn-lg btn-dark votebtn',
                'data-vote' => -1,
                'data-row' => $model->id
           ]
      ]);
}
