在Yii上传文件不显示图像名称/路径

Question

即时通讯这里再次出现一个新问题。我正尝试使用yii上传功能上传文件。

一切都很好，免去了形象。这里是我的代码：

控制器：

public function actionUpdate($id) 
    { 
     $model=$this->loadModel($id); 
     $dir = Yii::getPathOfAlias('webroot.images.producten'); 
     // Uncomment the following line if AJAX validation is needed 
     // $this->performAjaxValidation($model); 

     if(isset($_POST['Producten'])) 
     { 
      $model->attributes=$_POST['Producten']; 
      $model->images=CUploadedFile::getInstance($model,'images'); 
      $nf = $model->images; 

      if($model->save()){ 
       $this->redirect(array('view','id'=>$model->id)); 
       $model->images->saveAs($dir.'/'.$nf); 
       $model->images = $nf; 
       $model->save(); 
      } 
     } 

     $this->render('update',array(
      'model'=>$model, 
     )); 
    } 

形式：

<div class="row"> 
    <?php echo $form->labelEx($model,'images'); ?> 
    <?php echo CHtml::activeFileField($model,'images'); ?> 
    <?php echo $form->error($model,'images'); ?> 
</div> 

型号：

public function rules() 
    { 
     // NOTE: you should only define rules for those attributes that 
     // will receive user inputs. 
     return array(
      array('naam, beschrijving, prijs', 'required'), 
      array('images,', 'file', 'allowEmpty'=>true, 
       'safe' => true, 
       'types'=> 'jpg, jpeg, png, gif', 
       'maxSize' => (1024 * 300), // 300 Kb 
      ), 
      array('aangepast_door', 'numerical', 'integerOnly'=>true), 
      array('naam', 'length', 'max'=>50), 
      array('prijs, actieprijs', 'length', 'max'=>10), 
      //array('toegevoegd, aangepast', 'safe'), 
      // The following rule is used by search(). 
      // @todo Please remove those attributes that should not be searched. 
      array('naam, beschrijving, prijs, actieprijs', 'safe', 'on'=>'search'), 
     ); 
    } 

请帮我得到这个工作。

首先将enctype =“multipart/form-data”添加到窗体标记中，或者将“enctype”选项添加到关联数组中，如果使用窗体小部件yo begin form。 如果它不会帮助你，请发帖var_dump($_POST)结果
