我之前发布过，但有更多信息，所以想再试一次。我正在尝试帮助一位朋友解决他的网页上的联系表格问题，该网页是使用 SiteMan 构建的。他的页面上有一个基本的“联系我”表格和一个“请求报价”表格。该页面是 meadowwoodpedestals.com，它托管在 BlueHost 上。这些表格已经工作了多年，但我们刚刚发现他没有收到通过这些表格发送的消息。经过测试，我们发现当点击任一页面的提交按钮时，并没有得到确认屏幕，而是显示一个空白屏幕并且没有发送任何消息。自从他对 SiteMan 编辑器进行任何更改以来已经有几个月了。
（1）我联系了楼主寻求支持，回复告诉我报错说明这两个页面的页面代码有问题：
脚本头过早结束：500.php，引用者：http ://www.meadowwoodpedestals.com/content/index.php?page=quote
脚本头过早结束：500.php，引用者：http ://www.meadowwoodpedestals.com/content/index.php?page=contact
回复说：如您所见，问题似乎出在代码本身上。您需要让您的网页设计师或脚本专家查看这两个页面的代码，以解决这些问题。（我的注意：网页设计师倒闭了）
(2) 我在 Bluehost 论坛（这是一个 bluehost 网站）中发现了以下内容，我不确定它是否相关？
“Bluehost 服务器上脚本头的过早结束很可能是由于 CPU 配额（或内存？），脚本由于资源限制而被终止。”
(3) 我查看了联系表单的页面代码，它使用 method="post" action="/cgi-bin/frmctact.php" 并且所有基本的 html 看起来都不错 - 我不知道 javascript 所以我对此不确定（我以前从未见过那个小十字符号？）：
<script type="text/javascript" language="javascript">
function m_sfcon (u) {
pre = "mail";
url = pre + "to:" + u;
document.location.href = url + "@meadowwoodpedestals.com";
}†</script>
(4) 我查看了报价单的页面代码，它使用了method="post" action="/cgi-bin/mail/mail.php"，该页面上根本没有脚本标签。
（5）没有发布大量代码（因为我不确定什么是有用的），这是我的想法，如果这是一个合理的轨道，请告诉我：
- 由于有两个不同的页面具有相同的错误，我认为这在 quote.php 或 contact.php 中都不是问题
- 这两种形式使用不同的动作，所以我猜它不是 mail.php 或 frmctact.php
- ==> 两个页面之间一定有一些共同点，但它是什么？也许index.php？
(6) 我查看了 index.php，当我单击开始的 php 标记时，它以该语句第六行中的标记关闭（'si' 之前的？>）：
$adress = "http://" . $_SERVER['HTTP_HOST'] . dirname($_SERVER['PHP_SELF']);
include("data/page_header.php");
switch ($do) {
case "prevphp":
if ($Siteman->mlevel >= 4) {
echo preg_replace("'<\?php.*?\?>'si","",stripslashes($_POST["content"]));
}
break 1;
case "default":
if ($info[2] == 1 || $Siteman->mlevel >= $info[2]) {
include_once($content);
if ($Siteman->mlevel < 5) {
if ($page == "index") {
if (substr_count($_SERVER["HTTP_REFERER"],$adress) == 0) {
echo "<script language=\"Javascript\" type=\"text/javascript\">
var res = screen.width.toString() + 'x' + screen.height.toString();
var referer = '" . urlencode($_SERVER["HTTP_REFERER"]) . "';
document.write('<img width=\"1\" height=\"1\" src=\"stats.php?new=1&res=' + res + '&referer=' + referer + '\" id=\"stat\" name=\"stat\" />');
</script>";
}
}
}
}
break 1;
}
include("data/page_footer.php");
?>
（我不知道为什么这个页面的地址拼写错误......）
我应该将 cgi-bin/mail/mail.php 和 cgi-bin/frmctact.php 中的完整代码发布到该区域吗？
我真诚地感谢任何/所有帮助！艾比
编辑 - 这是完整的 frmctact.php - 我删除了一些空白行并重复警告
