我是Yii2中的新手而且我没有尝试在视图中显示数据。我之前就这样做了(使用GridView):

GridView::widget([
    'dataProvider' => $dataProvider,
    'filterModel' => $searchModel,
    'columns' => [
        ['class' => 'yii\grid\SerialColumn'],
        [
                'attribute' => 'car_id',
                'value' => 'car.state_num'
        ],
        [
            'attribute' => 'driver_id',
            'value' => 'driver.name'
        ],
        'status',
        'first_date',
         'second_date',
        // 'status',
        // 'foto:ntext',
        // 'description:ntext',

        ['class' => 'yii\grid\ActionColumn'],
    ],
]);

(它的视图显示'合约'表,其中包含'Driver'和'Car'表格)

但是现在我想通过常见的引导表来做,像这样:

<table class="table table-striped">
        <thead>
        <tr>
            <th scope="col">#</th>
            <th scope="col">Car</th>
            <th scope="col">Start</th>
            <th scope="col">Finish</th>
            <th scope="col">Status</th>
        </tr>
        </thead>
        <tbody>
        <?php foreach ($dataProvider->getModels() as $item):?>
        <tr>
            <th scope="row">Order ID <?= $item->id ?> </th>
            <td><?= $item->car_id ?></td>
            <td><?= $item->first_date ?></td>
            <td><?= $item->second_date ?></td>
            <td><?= $item->status ?></td>
        </tr>
        <? endforeach; ?>
        </tbody>
    </table>

它也有效,但Car的专栏显示了car_id .. 问题:如何在视图中显示car.state_num?

使用$item->car->state_num

<table class="table table-striped">
    <thead>
    <tr>
        <th scope="col">#</th>
        <th scope="col">Car</th>
        <th scope="col">Start</th>
        <th scope="col">Finish</th>
        <th scope="col">Status</th>
    </tr>
    </thead>
    <tbody>
    <?php foreach ($dataProvider->getModels() as $item):?>
    <tr>
        <th scope="row">Order ID <?= $item->id ?> </th>
        <td><?= (!empty($item->car_id)) ? $item->car->state_num : null ?></td>
        <td><?= $item->first_date ?></td>
        <td><?= $item->second_date ?></td>
        <td><?= $item->status ?></td>
    </tr>
    <? endforeach; ?>
    </tbody>
</table>
