Question

尝试进行客户端和服务器端验证我有2个文件。客户端很好，似乎服务器端出错，它根本不发送。

感谢。

form.php的：

<html>
<head>
<style type="text/css">
label.error{color:red; font-weight:bold;}
</style>
<script type="text/javascript" src="jquery.js"> </script>
<script type="text/javascript" src="validation.js"> </script>
<script type="text/javascript"> 
$.validator.setDefaults({
    submitHandler: function() { alert("submitted!"); }
});

$().ready(function() {
    // validate the comment form when it is submitted
    $("#commentForm").validate();

    // validate signup form on keyup and submit
    $("#signupForm").validate({
        rules: {
            firstname: "required",

检查eregi正则表达式是否真的有效（不推荐使用eregi，顺便说一句，你应该切换到preg_match
检查mail()函数的返回值 - 如果将电子邮件切换到本地SMTP服务器时出现问题，则邮件将返回布尔值FALSE。
查看SMTP服务器的日志 - 邮件可能卡在队列中，被接收服务器拒绝，转储到垃圾邮件文件夹等等......仅仅因为mail()返回true并不意味着该电子邮件实际上已发送给收件人。

为什么这个联系表格不起作用？
