記錄沒有得到保存在數據庫表yii2

Question

我有taluka模型，我們選擇區和輸入儘可能多的talukas。 但記錄沒有保存。

public function actionCreate() 
    { 

     $model = new Taluka(); 

     if ($model->load(Yii::$app->request->post())) { 

       $talukaslist = $model->talukas; 

       if(is_array($talukaslist)) 
       { 

        foreach($talukaslist as $taluka) 
        { 
         if($taluka ==null) 
         { 
            return $this->render('create', [ 
            'model' => $model, 
            ]); 
         } 
         else 
         if($taluka!=null) 
         { 
         $talukaRecord = new Taluka(); 
         $talukaRecord->DistrictId = $model->DistrictId; 
         $talukaRecord->Taluka = $taluka; 
         $talukaRecord->save(); 
         } 
        } 
       } 

       return $this->redirect(['index']); 
     } 

     else { 
      return $this->render('create', [ 
       'model' => $model, 


      ]); 
     } 
    } 

如果我使用$ talukaRecord-> save（false），那麼即使驗證失敗，記錄也會被保存。

型號：

use Yii;

請嘗試以下代碼

public function actionCreate() 
    { 

     $model = new Taluka(); 

     if ($model->load(Yii::$app->request->post())) { 

       $talukaslist = $model->talukas; 

       if(isset($talukaslist) && && $talukaslist!=array()) 
       { 

        foreach($talukaslist as $taluka) 
        { 
         if(isset($taluka) && $taluka ==null) 
         { 
            return $this->render('create', [ 
            'model' => $model, 
            ]); 
         } 
         else 
         if(isset($taluka) && $taluka!=null) 
         { 
          $talukaRecord = new Taluka(); 
          $talukaRecord->DistrictId = $model->DistrictId; 
          $talukaRecord->Taluka = $taluka; 
          if($talukaRecord->save()) 
          {} 
          else 
          { 
           echo "<pre>"; 
           print_r($talukaRecord->getErrors());die; 
          } 

         } 
        } 
       } 

       return $this->redirect(['index']); 
     } 

     else { 
      return $this->render('create', [ 
       'model' => $model, 


      ]); 
     } 
    }
