我试图阻止垃圾邮件与我的形式之一使用隐藏字段的技巧，但由于某种原因，它不工作。当我填写应该留空的字段时，表单就像正常一样提交。隐藏表单字段 - 我做错了什么？
我的php有什么问题吗？ （我想这就是我的问题所在）： 这是验证隐藏字段代码（见我的窗体顶部）：
if(!empty($_POST['email'])){ die('Stop Spamming'); }
下面是完整的PHP形式：
<?
session_start();
include("verification_image.class.php");
$image = new verification_image();
if (($image->validate_code($_POST['validate']) ? "true" : "false") == "false") {
header('Location: http://www.domain.com/fail.htm');
exit;
}
if(!empty($_POST['email'])){ die('Stop Spamming'); }
$to = "[email protected]";
$bcc = "[email protected]";
$from = $_POST['contactemail'];
$subject = "INTERESTED ADVERTISER";
$sbody = '<table width="420" height="135" border="0" align="center"
cellpadding="0" cellspacing="0">
<!--DWLayoutTable-->

继承人这个是我加入到我的HTML表单：
<label>
<input type="text" class="email" name="email" id="email" />
</label>
而且继承人的HTML表单：
<form action="process_advertise.php" method="post" name="order"
onSubmit="MM_validateForm('contactname','','R','contactnumber','','R','contactemail',
'','RisEmail','validate','','R','contactquery','','R');return document.MM_returnValue">
<input name="success" type="hidden"
value=http://www.domain.com/success.htm>

<!--DWLayoutTable-->

<input type="submit" name="button" id="button" value="Submit" /></td>
</tr>
</table>
</form>
任何人都知道我在做什么错了？
============================================== ========================= 问题解决：
好吧，我已经测试了表单，现在它的工作！ 我不是它为什么不早点工作，但对于那些谁想要知道......我所有的编码有是正确的，除了我从我的处理PHP形式移除了这个代码：
$sbody = '<table width="420" height="135" border="0" align="center"
cellpadding="0" cellspacing="0">
<!--DWLayoutTable-->
<tr>
<td height="90" colspan="5"><div align="center">Reservation &
Enquiries Submission Form </div></td>
</tr>
<tr>
<td height="25" colspan="3" align="center" valign="middle"><span
class="style7">Full Name</span></td>
<td width="180" valign="top">'.$_POST['contactname'].'</td>
<td width="42"> </td>
</tr>
<tr>
<td height="25" colspan="3" align="center" valign="middle"><span
class="style7">Contact number</span></td>
<td valign="top">'.$_POST['contactnumber'].'</td>
<td> </td>
</tr>
<tr>
<td height="25" colspan="3" align="center" valign="middle"><span
class="style7">Email</span></td>
<td valign="top">'.$_POST['contactemail'].'</td>
<td> </td>
</tr>
<tr>
<td height="35" colspan="3" align="center" valign="bottom"><span
class="style7">Query</span></td>
<td colspan="2" rowspan="2"
valign="middle">'.$_POST['contactquery'].'</td>
</tr>
<tr>
<td width="84" height="108" align="center" valign="middle">
<!--DWLayoutEmptyCell--> </td>
<td width="69" align="center" valign="middle"><!--DWLayoutEmptyCell-->&
nbsp;</td>
<td width="17"> </td>
</tr>
<tr>
<td height="17"></td>
<td></td>
<td></td>
<td></td>
<td></td>
</tr>
