Question

Arrg。

我可以发现这种接触形式中的无休止的漏洞。表格提交后,“比克”无休止地印刷。我失踪了什么? 错误是没有的,还是错? (在工作档案中,通过<代码><script category=“text/javascript” src=“contact.js”></script>)

我对你的代码做了一些改动,然后用我的当地机器进行工作,看看这是否对你有用。

 <?php 
 if(isset($_POST[ submitted ])) {
    if(trim($_POST[ checking ]) !==   ) {
        $captchaError = true;
    }else{
        if(trim($_POST[ email ]) ===   )  {
            $emailError =  Please enter a valid email address ;
            $hasError = true;
        } else if (!eregi("^[A-Z0-9._%-]+@[A-Z0-9._%-]+.[A-Z]{2,4}$", trim($_POST[ email ]))) {
            $emailError =  That s not a valid email address ;
            $hasError = true;
        } else {
            $email = trim($_POST[ email ]);
        }
    }

    if(!isset($hasError)) {
        $emailTo =  to email ;
        $subject =  site email ;
        $body = "$email";
        $headers =  From: webmail ;
        mail($emailTo, $subject, $body, $headers);
        $emailSent = true;
    }
 }

Answer 2

它希望你在具备现有要素(四)的同时,再尝试增加一个要素(<p等级=“thanks”)。您能否缩小其中的界限? 另外,还有<代码>$(“#thanks”)。 fadeOut ,但t似乎没有任何内容,其编号为<>id。

我建议更仔细地通过该守则。我看不到一种无休止的 lo,但如果出于某种原因,这种功能一再被启动,就会出现同样的症状。
