使用多年的联系表格已失效

Question

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单问题，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，托管在 BlueHost 上。这些表格已经有效多年，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，当单击这些页面中的任何一个页面的提交按钮时，不会显示确认屏幕，而是显示空白屏幕，并且不会发送任何消息。他已经有几个月没有在 SiteMan 编辑器中进行任何更改了。

(1) 我联系楼主寻求支持，回复告诉我错误表明这两个页面的页面代码有问题：

Premature end of script headers: 500.php,referer: http://www.meadowwoodpedestals.com/content/index.php?page=quote

过早脚本标头结束：500.php，引用：http://www.meadowwoodpedestals。 com/content/index.php?page=contact

响应说： 正如您将看到的，问题似乎出在代码本身。您需要让网页设计师或脚本专家检查这两个页面的代码，才能解决这些问题。 （我的注：网页设计师已经失业了）

（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？

“在 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 html 看起来都不错 - 我不知道 javascript，所以我我对此不确定（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）我查看了报价表单的页面代码，它使用 method="post" action="/cgi-bin/mail/ mail.php”，并且根本没有脚本标签那个页面。

（5）在不发布大量代码的情况下（因为我不确定什么是有用的），这是我的想法，请让我知道这是否是一个合理的轨道：

• 由于有两个不同的页面有相同的错误，我'我认为 quote.php 或 contact.php 中都不是真正的问题
• 这两种表单使用不同的操作，所以我猜测它不是 mail.php 或 frmctact.php
• ==>两个页面之间肯定有一些共同点，但它是什么呢？也许是index.php？

(6) 我查看了index.php，当我单击开始的 php 标签时，它以该语句第六行中的一个标签关闭（“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&amp;res=' + res +      '&amp;referer=' + referer + '\" id=\"stat\" name=\"stat\" />');
                    </script>";
                }
            }
        }
    }
    break 1;
}
include("data/page_footer.php");

?>

我不知道知道为什么此页面的地址拼写错误...）

完整代码发布到此区域吗？

我应该将 cgi-bin/mail/mail.php 和 cgi-bin/frmctact.php 中的 艾比

编辑 - 这是完整的 frmctact.php - 我删除了一些空行和重复警告

    // If you have set $required_on to "yes" above, you can make fields required

Answer 1

500 错误意味着 PHP 正在崩溃。您需要查看 apache 错误日志（bluehost 在 cpanel、IIRC 中有一个图标），希望能看到一些 PHP 错误消息。

[人们说]“该脚本由于资源限制而被终止。”

我认为不是这个，因为500错误是在提交表单后立即发生的。
