记录未保存在yii2的数据库表中

我有塔鲁卡模型，我们选择地区，输入尽可能多的塔鲁卡。 但是这些记录没有被保存

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），那么即使验证失败，记录也会被保存

型号：

class Taluka extends \yii\db\ActiveRecord
{
    /**

    public $talukas=[];

    public static function tableName()
    {

    }

请尝试下面的代码

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,


            ]);
        }
    }

公共函数actionCreate（）
{
$model=new Taluka（）；
如果（$model->load（Yii:：$app->request->post（））{
$talukaslist=$model->talukas；
if（isset（$talukaslist）&&&&&&$talukaslist！=array（））
{
foreach（$Talukas列为$taluka）
{
如果（isset（$taluka）&&$taluka==null）
{
返回$this->render（'create'[
'model'=>$model，
]);
}
其他的
如果（isset（$taluka）&&$taluka！=null）
{
$talukaRecord=新Taluka（）；
$talukaRecord->DistrictId=$model->DistrictId；
$talukaRecord->Taluka=$Taluka；
如果（$talukaRecord->save（））
{}
其他的
{
回声“；
打印（$talukaRecord->getErrors（））；死亡；
}
}
}
}
返回$this->redirect（['index']）；
}  
否则{
返回$this->render（'create'[
'model'=>$model，
]);
}
}
然后，它会按预期工作，对吗？检查模型验证失败的原因尝试打印（$talukaRecord->getErrors（））

，以检查哪些验证规则失败。使用model Taluka.php文件更新您的问题。我为所选地区输入的两个Taluka可能重复，并显示以下数组（[talukas]=>Array（[0]=>Taluka不能为空。））数组（[talukas]=>Array（[0]=>Taluka不能为空。）代码不起作用，即使输入了所有值，错误仍显示为数组（[talukas]=>Array（[0]=>talukas不能为空。））
