我已经看到很多关于这种症状的问题，但没有一个答案似乎能解决我的问题。我收到这样的通知（其中15个，每个从表单传递的变量一个），结果是用户看到的页面是空白的。
注意：未定义的索引：第3行的C：\ Web Files \ www.iusc.org \ scripts \ send_form_email.php中的FirstName
然而，当我在Firefox中使用Firebug查看POST时，我看到变量（全部15个）已正确填充。
根据请求，我将包含所有这两个文件。这是HTML部分的大部分内容，我不允许发布它，它超出了大小限制：

答案 0 :(得分：1)
然而，当我在Firefox中使用Firebug查看URL时，我看到变量（全部15个）已正确填充。
您正在使用$_POST变量，但上述情况表明变量已附加到网址，此类型为$_GET
如果您想要POST变量，它们将在标题中发送，并且在URL中对用户不可见。为此，请更改表单方法。
<form method="POST" ...
否则，只需将$_POST更改为$_GET
