Php Yii2 GridView搜索相关下拉列表

我正在使用Yi2 gridview加载国家、州和城市。我使用下拉菜单设置了国家、州、城市的搜索选项。如何在过滤器中创建相关下拉列表

<?= GridView::widget([
    'dataProvider' => $dataProvider,
    'filterModel' => $searchModel,
    'columns' => [
         [
        'attribute' => 'country_id',
        'label' => 'Country',
        'filter' => Country::country(),
        'value' => function($data){
        return Country::countryname($data->country_id);
        }
         ],
        [

          'attribute' => 'state_id',
          'filter' => State::state(),
          'value' => function($data){
            return State::statename($data->state_id);
          }
        ],
         [

          'attribute' => 'city_id',
          'filter' => City::city(),
          'value' => function($data){
            return City::cityname($data->city_id);
          }
        ],

]); ?>

由于网格视图中的筛选表单更改，因此在表单更改时发送请求。。 您可以根据需要轻松创建过滤器列表

<?= GridView::widget([
    'dataProvider' => $dataProvider,
    'filterModel' => $searchModel,
    'columns' => [
         [
        'attribute' => 'country_id',
        'label' => 'Country',
        'filter' => Country::country(),
        'value' => function($data){
        return Country::countryname($data->country_id);
        }
         ],
        [

          'attribute' => 'state_id',
          'filter' => State::state($searchModel->country), //Country Id/name from SearchModel --- you can add condition if isset($searchModel->country) then show else [] blank array
          'value' => function($data){
            return State::statename($data->state_id);
          }
        ],
         [

          'attribute' => 'city_id',
          'filter' => City::city($searchModel->state),   //Country Id/name from SearchModel --- you can add condition if 
          'value' => function($data){
            return City::cityname($data->city_id);
          }
        ],

]); ?>

城市模型也一样，因为网格视图中的过滤器表单会在表单更改时更改发送请求。。 您可以根据需要轻松创建过滤器列表

<?= GridView::widget([
    'dataProvider' => $dataProvider,
    'filterModel' => $searchModel,
    'columns' => [
         [
        'attribute' => 'country_id',
        'label' => 'Country',
        'filter' => Country::country(),
        'value' => function($data){
        return Country::countryname($data->country_id);
        }
         ],
        [

          'attribute' => 'state_id',
          'filter' => State::state($searchModel->country), //Country Id/name from SearchModel --- you can add condition if isset($searchModel->country) then show else [] blank array
          'value' => function($data){
            return State::statename($data->state_id);
          }
        ],
         [

          'attribute' => 'city_id',
          'filter' => City::city($searchModel->state),   //Country Id/name from SearchModel --- you can add condition if 
          'value' => function($data){
            return City::cityname($data->city_id);
          }
        ],

]); ?>

如果$searchModel是ModelSearch的一个对象，则与城市模型相同，在视图中：

$this->registerJs( <<< EOT_JS

      $('#ModelSearch[state_id]').on('change', function(ev) {
            $.get(
                '<url>',
                { parameters }
                function(data) { 
                      // if data is an html response...
                      $('#ModelSearch[city_id]').html(data);
                }
            );
      }

EOT_JS
);

$this->registerJs（如果$searchModel是ModelSearch的对象，则在视图中：

$this->registerJs( <<< EOT_JS

      $('#ModelSearch[state_id]').on('change', function(ev) {
            $.get(
                '<url>',
                { parameters }
                function(data) { 
                      // if data is an html response...
                      $('#ModelSearch[city_id]').html(data);
                }
            );
      }

EOT_JS
);

你可以做得越来越简单。例如，我有带眼镜的剧院，所以我的gridview是：

<?= GridView::widget([
    'dataProvider' => $dataProvider,
    'filterModel' => $searchModel,
    'columns' => [
        ['class' => 'yii\grid\SerialColumn'],
        'id',
        [
            'attribute' => 'theatre_id',
            'value' => 'theatre.title',
            'header' => '',
            'filter' => Html::activeDropDownList($searchModel, 'theatre_id', ArrayHelper::map(Theatre::find()->asArray()->all(), 'id', 'title'),['class'=>'form-control','prompt' => 'Select theatre']),
        ],
        [

                    ArrayHelper::map(Spectacle::find()->asArray()->all(), 'id', 'title'):
