    }elseif(empty($_FILES['fileToUpload']['tmp_name']) || $_FILES['fileToUpload']['tmp_name'] == 'none'){
        $error = 'No file was uploaded..';
    }else{
            $re = $this->up();
            if(!$re){
                $error = 'Up file fail';
            }
            $msg = $re['savename'];    //文件名
            $path = '/upload/bizcoop/'.$msg;    //文件路径
            $size = $re['size'];    //文件大小
    }
    echo json_encode(array('error'=>$error,'msg'=>$msg,'path'=>$path,'size'=>$size));exit;
}

private function up(){
    import('@.Org.UploadFile');//将上传类UploadFile.class.php拷到Lib/Org文件夹下
    $upload=new UploadFile();

    $upload->maxSize='-1';//默认为-1，不限制上传大小
$upload->savePath= ICTSPACE_DIST_ROOT_PATH.'/www/upload/bizcoop/';//Save path
