本款文件上传类，默认是上传单文件的,我们只要修改$inputname ='files'为你的表单名就可以方便的实现批量文件上传了。 $savename = ''保存文件名, $alowexts = array()设置允许上传的类型，$savepath = ''保存路径。
*/

代码如下

复制代码

class upload
{
public $savepath;
public $files;
private $error;

function __construct($inputname ='files', $savepath = '', $savename = '', $alowexts = array(),$maxsize = 1024000)
{
  if(!$alowexts)$alowexts=explode('|',upload_ftype);
  $file_array=array();
  $savepath=str_replace('','/',$savepath);
  $savename=preg_replace('/[^a-z0-9_]+/i','',$savename);
  $this->savepath=substr($savepath,-1)=='/'?$savepath:$savepath.'/'; //路径名以/结尾

  if(!make_dir($this->savepath))
  {
   $this->error=8;
   $this->error();
  }
  //exit($this->savepath);
  if(!is_writeable($this->savepath))
  {
   $this->error=9;
   $this->error();
  }
  if(sizeof($_files[$inputname]['error'])>10)
  {
   $this->error=13;
   $this->error();
  }
  $max=sizeof($_files[$inputname]['error'])-1;
  //exit($this->savepath.$savename);
  foreach($_files[$inputname]['error'] as $key => $error)
  {
   if($error==upload_err_ok) //批量上传
   {
    $savename=$savename?$savename:date('ymdims').mt_rand(10000,99999);
    $fileext=strtolower(get_fileext($_files[$inputname]['name'][$key]));
    $savename=$savename.'.'.$fileext;
    $tmp_name=$_files[$inputname]['tmp_name'][$key];
    $filesize=$_files[$inputname]['size'][$key];
    if(!in_array($fileext,$alowexts))
    {
     $this->error=10;
     $this->error();
    }
    if($filesize>$maxsize)
    {
     $this->error=11;
     $this->error();
    }
    if(!$this->isuploadedfile($tmp_name))
    {
     $this->error=12;
     $this->error();
    }

    if(move_uploaded_file($tmp_name,$this->savepath.$savename) || @copy($tmp_name,$this->savepath.$savename))
    {
     //exit($this->savepath.$savename);
     @chmod($savename, 0644);
     @unlink($tmp_name);
     $file_array[]=$this->savepath.$savename;
    }
   }
   else
   {
    $this->error=$error;
    $this->error();
   }
   unset($savename);
  }
  $this->files=$file_array;
  return true;
}

function isuploadedfile($file) //去掉系统自带的反斜线
{
return (is_uploaded_file($file) || is_uploaded_file(str_replace('','',$file)));
}

function error()
{
  $upload_error=array(0 => '文件上传成功 !',
       1 => '上传的文件超过了 php.ini 中 upload_max_filesize 选项限制的值 !',
       2 => '上传文件的大小超过了 html 表单中 max_file_size 选项指定的值 !',
       3 => '文件只有部分被上传 !',
       4 => '没有文件被上传 !',
       5 => '未知错误!',
       6 => '找不到临时文件夹。 !',
       7 => '文件写入临时文件夹失败 !',
       8 => '附件目录创建失败 !',
       9 => '附件目录没有写入权限 !',
       10 => '不允许上传该类型文件 !',
       11 => '文件超过了管理员限定的大小 !',
       12 => '非法上传文件 !',
       13 => '最多可同时上传10个文件 !'
       );
  showmsg($upload_error[$this->error]);
}

}

//使用方法

new upload();
