使用 GridView 在 Yii2.0 中显示过滤器的空白行

我已经设置 GridView 在 Yii2.0 中创建我的表，如下所示：

<?= \yii\grid\GridView::widget([
    'dataProvider' => $model->dataProvider,
    'filterModel' => $model->searchModel,
    'columns' => [
        [
            'label' => Yii::t( $cat, 'Id' ),
            'value' => 'id',
        ],
        [
            'label' => Yii::t( $cat, 'Title' ),
            'format' => 'raw',
            'value' => function ( $data ) {
                if ( $data['status_code'] != 5 )
                {
                    return Html::a( $data['title'], '/signer/view/' . $data['id'] );
                }
                else
                {
                    return $data['title'];
                }
            },
        ],
        [
            'label' => Yii::t( $cat, 'Description' ),
            'value' => 'description',
        ],
        [
            'label' => Yii::t( $cat, 'Filename' ),
            'value' => 'filename',
        ],
        [
            'label' => Yii::t( $cat, 'Status' ),
            'value' => 'status',
            'contentOptions' => function ( $data ) {
                    $statuses = [
                        1 => 'text-primary',    # New
                        2 => 'text-warning',    # Unsigned
                        3 => 'text-warning',    # Partially signed
                        4 => 'text-success',    # Signed
                        5 => 'text-danger',     # Deleted
                    ];
                    return [ 'class' => $statuses[$data['status_code']] ];
                }
        ],
        [
            'label' => Yii::t( $cat, 'Created' ),
            'value' => 'created',
        ],
        //[ 'class' => 'yii\grid\ActionColumn' ],
    ],
]);
?>

我得到了所有正确的数据，但我得到的是空行，而不是过滤输入。

这是为什么？我缺少什么？

PS：搜索模型本身工作正常，这意味着，当我添加到网址时?title=asd它居然得到了搜索结果！

根据的文档$filterModel http://www.yiiframework.com/doc-2.0/yii-grid-gridview.html#%24filterModel-detail财产：

请注意，为了显示用于过滤的输入字段，列必须有其yii\grid\DataColumn::$attribute属性设置或具有yii\grid\DataColumn::$filter设置为输入字段的 HTML 代码。

所以你需要设置yii\grid\DataColumn::$attribute列上的属性，在大多数情况下，这使得value不必要：

<?= \yii\grid\GridView::widget([
    'dataProvider' => $model->dataProvider,
    'filterModel' => $model->searchModel,
    'columns' => [
        [
            'label' => Yii::t( $cat, 'Id' ),
            'attribute' => 'id',
        ],
        [
            'label' => Yii::t( $cat, 'Title' ),
            'format' => 'raw',
            'attribute' => 'title',
            'value' => function ( $data ) {
                if ( $data['status_code'] != 5 )
                {
                    return Html::a( $data['title'], '/signer/view/' . $data['id'] );
                }
                else
                {
                    return $data['title'];
                }
            },
        ],
        [
            'label' => Yii::t( $cat, 'Description' ),
            'attribute' => 'description',
        ],
        [
            'label' => Yii::t( $cat, 'Filename' ),
            'attribute' => 'filename',
        ],
        [
            'label' => Yii::t( $cat, 'Status' ),
            'attribute' => 'status',
            'contentOptions' => function ( $data ) {
                    $statuses = [
                        1 => 'text-primary',    # New
                        2 => 'text-warning',    # Unsigned
                        3 => 'text-warning',    # Partially signed
                        4 => 'text-success',    # Signed
                        5 => 'text-danger',     # Deleted
                    ];
                    return [ 'class' => $statuses[$data['status_code']] ];
                }
        ],
        [
            'label' => Yii::t( $cat, 'Created' ),
            'attribute' => 'created',
        ],
        //[ 'class' => 'yii\grid\ActionColumn' ],
    ],
]);
