我对 php yiiframework 很陌生。我有用户模型,其中包含用户基本信息,包括个人资料图像,但是当我为我的个人资料更新新图像时,我必须删除图像文件。我使用以下方法上传了文件。

public function actionUpdate()
    {
        $model=$this->loadModel($id);    
        $random = substr(number_format(time() * rand(),0,'',''),0,10);          
        if(isset($_POST['Users']))
        {                           
            $model->attributes=$_POST['Users'];             
            $uploadedFile=CUploadedFile::getInstance($model,'image_path');
            $fileName = $milliseconds. '-' .$random;
            $model->image_path = $fileName;

            if($model->save())              
                $uploadedFile->saveAs(Yii::app()->basePath.'/../images/uploaded/'.$fileName);
                $this->redirect(array('view','id'=>$model->id));
        }    
        $data = PanXCore::getDataForCreateUser();
        $userRoles = new UserRoles();
        $this->render('create',array(
            'model'=>$model,
                'roles' => $data['roles'],
                'userRoles' => $userRoles               
        ));
    }

unlink()例如使用

unlink(Yii::app()->basePath.'/../images/uploaded/'. $oldfile);
