     #---- 過濾資料 --------------------------
     $myts = &MyTextSanitizer::getInstance();
    
     #先判斷是否有填值
     if($required == true and $var === ""){
       redirect_header(XOOPS_URL, 3,"{$title}為必填！");
     } 
     if($type == "string"){
       $var = $myts->addSlashes($var);//文字
     }elseif($type == "int"){
       $var = intval($var);//整數
     }elseif($type == "float"){
