机缘巧合，再次接触到Yii2框架的项目，做了简单的增删查改。涉及到列表项下拉筛选框，自定义表格显示内容。

以下内容仅摘抄了代码最核心的部分，仅供参考

• 模型

  class AdvertRecordSearch extends AdvertRecord
  {
      public $start_date;
  
      public $end_date;
  
      public $platforms = [
          'tencent' => '腾讯',
          'alibaba' => '阿里',
      ];
  
      public function rules()
      {
          return [
              [['start_date', 'end_date'], 'safe'],
              ['platform', 'in', 'range' => array_keys($this->platforms)],
          ];
      }
  }
  

• 控制器

  class AdvertRecordController extends Controller
  {
      public function actionIndex()
      {
          $searchModel = new AdvertRecordSearch();
          $dataProvider = $searchModel->search(Yii::$app->request->queryParams);
  
          return $this->render('index', [
              'searchModel' => $searchModel,
              'dataProvider' => $dataProvider
          ]);
      }
  }
  

• 视图

  <?= \yii\grid\GridView::widget([
      'dataProvider' => $dataProvider,
      'filterModel' => $searchModel,
      'columns' => [
          'date',
          [
              'attribute' => 'platform',
              'filter' => Html::dropDownList('platform', $searchModel->platform, $searchModel->platforms, ['class' => 'form-control', 'prompt' => '全部']),
              'value' => function ($model) {
                  return ArrayHelper::getValue($model->platforms, $model->platform);
              }
          ],
          'total',
      ]
  ])?>
