请参阅原始问题下方的更新：

我的联系表格有问题。我对 PHP 还很陌生，但是直到最近，当一个不相关的问题需要我的主机时，他们一直在努力……CBeyond :(……从 ISAPI 切换回 CGI。知道这不是那么灵活（最新) 的一项技术，我对这项技术比较熟悉，所以我可以接受。

问题开始于我的联系表格切换后都显示“未定义索引”错误。

我的所有代码都在同一个页面上（表单、处理、验证、谢谢），我正在努力找出问题所在。我确信有一些关于额外验证等的建议，但现在......我只需要这个表格就可以了。

其中一种形式：www.faa-air.com/contact/php/mailer.php 提交正确，但页面底部出现乱码。

另一种形式：www.faa-air.com/contact/php/consultmailer.php 未正确提交。它发送表单的结果，但它是空白的，网页底部仍然有所有乱码。

下面是一个不起作用的代码（consultmailer.php），但两者都是相互开发的，所以它们在逻辑上应该是相同的......所以不确定出了什么问题。

有任何想法吗？

更新

我能够让表格正确发送但改变了，

$f_name = $_GET['f_name'] ;

到 $f_name = $_REQUEST['f_name'] ;

我确信存在一些问题（我还是新手），但它确实有效。

我仍然收到我无法理解的 E_NOTICE 错误。我喜欢 E_NOTICE，所以如果我错过了冒号或其他东西，我可以很容易地找到它，但是我做的没有任何帮助。我很感激这个建议，并希望我能在我的错误通知中得到更多的回应。

改变的只是你的错误报告级别。它现在包括E_NOTICE.

您需要在使用它们之前检查数组索引和变量。例如，而不是...

if ($_POST['f_name'] == '')

利用

if (empty($_POST['f_name']))

这是因为empty在可能未定义的变量/索引上使用是安全的。

还有一个，这个...

$f_name = $_GET['f_name'];

是安全的

$f_name = isset($_GET['f_name']) ? $_GET['f_name'] : null; // or whatever you want to use as a default value.

$message最后，在将字符串与连接运算符 ( ) 一起使用之前，您应该为字符串分配一个初始值.=，例如

// as this is the first appearance of $message, just assign the initial value directly
$message = 'The following request was submitted by ' .$f_name. ' ' .$l_name. "\n\n";
