Zend Framework上传文件重命名的实现方法

//实例化文件上专类$fName=$this->_request->getPost('fName');$adapter = new Zend_File_Transfer_Adapter_Http();//存放上传文件的文件夹$adapter->setDestination('/opt/lampp/htdocs/blog/upload');//上传配置$adapter->addValidator ( 'Extension', false, $configs['extension'])//文件格式限制->addValidator('Size', false, array('min' =>floatval($configs['minsize']),  'max' => floatval($configs['maxsize'])))//设置上传文件的大小在1-2M之间->addValidator ( 'Count', false, array('min' => intval($configs['mincount']),  'max' => intval($configs['maxcount'])) );//上传文件数量//重命名配置$fileInfo = $adapter->getFileInfo();//获取基本配置$extName=$this->getExtension($fileInfo);//获取扩展名$filename=md5(time()+$fileInfo['fFile']['name']).'.'.$extName;//重命名$adapter->addFilter('Rename', array('target' => $filename, 'overwrite' => true));//执行重命名//返回上传后出现在信息if (!$adapter->receive()){  $messages = $adapter->getMessages ();//检测  //Zend_Debug::dump($messages);  $message='';  if(is_array($messages))  {    foreach($messages as $k=>$v)    {      $message.=$k.':'.$v.'<br>';    }  }  else  {    $message=$messages;  }}else{  $this->view->message='上传成功！';}
