记录未保存在yii2的数据库表中

Question

我有taluka模型选择地区，并且输入尽可能多的talukas。 但记录没有得到保存。

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-＆gt; save（false），那么即使验证失败，记录也会被保存。

请尝试以下代码

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,


            ]);
        }
    }
