yiiframework動作刪除不顯示setflash

Question

public function actionDelete($id) 
{ 
    if(Yii::app()->request->isPostRequest) 
    { 
     // we only allow deletion via POST request 
     try 
     { 
      $this->loadModel($id)->delete(); 
      // if AJAX request (triggered by deletion via admin grid view), we should not redirect the browser 
       if(!isset($_GET['ajax'])) 
        $this->redirect(isset($_POST['returnUrl']) ? $_POST['returnUrl'] : array('admin'));   
     } 
     catch (Exception $e) 
     { 
      throw new CTestException('User in use, Delete Refrences.'); 
      //Yii::app()->user->setFlash ('error', "User in use, Delete Refrences."); 
     } 


    } 
    else 
    { 
     throw new CHttpException(400,'Invalid request. Please do not repeat this request again.'); 
    } 
} 

我想捕捉內部異常並顯示警報。它的setflash不工作，如果我拋出一個自定義的異常，它也警告錯誤500堆棧，我試圖處理的異常。

您需要在throw之前放置setFlash調用，因爲throws以類似返回語句的方式結束函數。

另外，取消聲明。
