    $msg = "";
    $fileElementName = 'fileToUpload';
    if(!empty($_FILES[$fileElementName]['error'])){
        switch($_FILES[$fileElementName]['error']){
            case '1':
                $error = 'The uploaded file exceeds the upload_max_filesize directive in php.ini';
                break;
            case '2':
                $error = 'The uploaded file exceeds the MAX_FILE_SIZE directive that was specified in the HTML form';
                break;
            case '3':
                $error = 'The uploaded file was only partially uploaded';
                break;
            case '4':
                $error = 'No file was uploaded.';
                break;

            case '6':
                $error = 'Missing a temporary folder';
                break;
            case '7':
                $error = 'Failed to write file to disk';
                break;
            case '8':
                $error = 'File upload stopped by extension';
                break;
            case '999':
            default:
                $error = 'No error code avaiable';
        }
    }elseif(empty($_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/';//保存路径
    $upload->saveRule=uniqid;//上传文件的文件名保存规则
    $upload->uploadReplace=true;//如果存在同名文件是否进行覆盖
    $upload->allowExts=array('jpg','jpeg','png','gif');//准许上传的文件类型
    if($upload->upload()){
        $info=$upload->getUploadFileInfo();
        return $info[0];
    }else{
        return false;
        exit;
    }
}
}
