这篇文章主要介绍了Zend Framework上传文件重命名的实现方法,结合实例形式分析了Zend Framework上传文件重命名的具体操作步骤与配置、检测、重命名操作的相关实现技巧,需要的朋友可以参考下

本文实例讲述了Zend Framework上传文件重命名的实现方法。分享给大家供大家参考,具体如下:

1. Zend Framework文件上传重命名

//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.&#39;:&#39;.$v.&#39;<br>&#39;;
    }
  }
  else
  {
    $message=$messages;
  }
}
else
{
  $this->view->message=&#39;上传成功!&#39;;
}

2. 获取文件扩展名

/**
 * 获取文件扩展名
 * @param String $name 文件名词
 * @author
 */
public function getExtension ($name)
{
  $fname=&#39;&#39;;
  if($name)
  {
    foreach ($name as $val)
    {
      $fname=$val[&#39;name&#39;];
    }
    $exts = @split("[/\\.]", $fname) ;
    $n = count($exts)-1;
    $exts = $exts[$n];
    return $exts;
  }
}
