好的，我有点困惑，因为这段代码正在运行，并且出于某种原因已经停止了。不确定它什么时候停止工作，但是这个网站上的某个人为我创建了它并且它在工作时非常完美。该人将我的mailer.php，重定向页面和html代码组合在一个非常棒的页面中。提交的成功页面有效，但错误的验证码错误会自动停止工作（？）。
以下是代码：
<?php
$state = 0;
// check to see if verificaton code was correct
if(md5($verif_box).'a4xn' == $_COOKIE['tntcon']){
// if verification code was correct send the message and show this page
mail("myemail@hotmail.com", 'Website Inquiry '.$subject, "\n\n".'Name: '.$name."\n\n".'Company: '.$company."\n\n".'Phone Number: '.$phone."\n\n".'Contact Me By: '.$ContactMethod."\n\n".'City: '.$city."\n\n".'I am Interested In: '.$InterestedIn."\n\n".'Comments: '.$comments."\n\n".$from."\n\n".$_SERVER['REMOTE_ADDR'], "From: $email");
// delete the cookie so it cannot sent again by refreshing this page
setcookie('tntcon','');
$state = 2;
} else if(isset($message) and $message!=""){
// if verification code was incorrect then return to contact page and show error
$state = 1;
}
if ($state == 0) { ?>
<form action="" method="post" name="form1" id="form1" onsubmit="MM_validateForm('email','','RisEmail','name','','R','verif_box','','R','comments','','R');return document.MM_returnValue">
请填写下面的表格，让销售团队的人员与您联系
<p><strong>Tell us what you're interested in:</strong></p>
<dl>
<dd>
<input type="radio" name="InterestedIn" value="BIBS<?php echo $_GET['InterestedIn'];?>"> Blow-In-Blanket System
<input type="radio" name="InterestedIn" value="Spray Foam<?php echo $_GET['InterestedIn'];?>"> Soya Spray Foam

<input type="radio" name="InterestedIn" value="Not Sure<?php echo $_GET['InterestedIn'];?>" checked="checked"> Not Sure</dd>
</dl>
<p><strong>Enter additional comments* in the space provided below:</strong></p>
<dl>
<dd><textarea name="comments" cols="50" rows="5" border="0" id="comments"><?php echo $_GET['comments'];?></textarea></dd>
</dl>
<p><strong>Tell us how to get in touch with you:</strong></p>
<dl>
<dd>
<table>

<tr>
<td>City</td>
<td><input type="text" size="40" maxlength="256" name="city" value="<?php echo $_GET['city'];?>"></td>
</tr>
</table>
</dd>
</dl>
<p><strong>Best method to get in touch with you:</strong></p>
<dl>
<dd><input type="radio" name="ContactMethod" value="telephone<?php echo $_GET['InterestedIn'];?>" checked="checked"> Phone
<input type="radio" name="ContactMethod" value="email<?php echo $_GET['InterestedIn'];?>"> Email
</dd>
</dl>
<p style="padding-left:60px;"><input type="submit" class="button primary" value="Submit Form" name="submit"/>
<input type="reset" class="button primary" value="Clear Form" name"clear" /></p>
然后在/ html标记之后的页面底部：
<?php } else if ($state == 1) { ?>
<h3>Error</h3>
<p>Wrong Verification Code Entered - Go back and try again</p>
<?php } else if ($state == 2) { ?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
然后其余的html在这里...提交成功的页面然后关闭php标签。
为什么它停止工作的任何想法？有什么方法可以解决当前的代码吗？如果没有，我需要一些方法告诉用户表单他们提交了错误的验证码。目前，如果输入错误的代码，则只刷新当前页面。
非常感谢任何帮助。我不熟悉php，所以请使用lamens条款！
使用Javascript：
<script type="text/JavaScript">

答案 0 :(得分：0)
验证图像文件是一个很大的缺失部分。这就是设置cookie的地方。看起来脚本顶部的一行代码可能会被意外删除，从而导致您的问题。除非它没有被复制。我不知道你的验证图像的html字段名称是什么，但在最顶层你应该有类似的东西：
$ verif_box = $ _POST ['verification_field'];
您没有为$ verif_box变量设置值，因此它总是会失败。
