以下代码不起作用。 forms.php和forms.html是文件名，都保存在根目录中。

错误是“ Undefined variable: POST in C:\wamp\www\forms.php”。我知道我也没有正确处理多个输入。任何人都可以帮助解决这些问题吗？

<html>
<head>
<title>

</head>


<body>
<h1> Start your Placement process...NOW...</h1>
<form action = "forms.php" method = "POST">

代替$POST, 使用$_POST, 更多信息：

你应该这样写

$_POST['Name']
或
$_REQUEST['Name']

不太了解，但也许“双引号”会造成问题。尝试使用

$_POST['state'];

这可能会奏效。

您$_POST也不$POST应该检查变量是否已定义和设置，您还应该htmlspecialchars()在输出时使用用户输入来避免 XSS 漏洞：

<?php 
echo isset($POST['Name']) ? '<p>'.htmlspecialchars($_POST['Name']).'</p>' : null; 
?>
