使用PHP显示用户输入

What I'm trying to do is to use PHP to display the user inputs on a separate page, but when I process the form none of the input values display. I'm having to use javascript for input validation and that works fine but the PHP page is not working. Here is my code: HTML and Javascript

我要做的是使用PHP在单独的页面上显示用户输入,但是当我处理表单时,没有显示任何输入值。我必须使用javascript进行输入验证,并且工作正常,但PHP页面无效。这是我的代码:HTML和Javascript

survey.php:

  <!DOCTYPE html>
  <html>

  <head>
    <title>Survey Page</title>
    <link rel="stylesheet" type="text/css" href="mystylepage.css" />

    <script type="text/javascript">
    function validate()
    {

        if (document.information.name.value == "" )
        {
            alert("Please provide your name!" );
            document.information.value.focus();
            return false;
        }
        if (document.information.email.value == "")
        {
            alert("Please provide an email!");
            document.information.value.focus();
            return false;
        }
        if (document.information.major.value == false)
            {
                alert("Please enter your major");
                document.information.value.focus();
                return false;
            }
        return true;
    }

    </script>
  </head>

  <div id="bodycolor">

Here is the PHP page:

这是PHP页面:

</head>

<body>

<h1>Form data</h1>
<p>Name: <?php echo $_POST["name"]?></p>

<p>Email: <?php echo $_POST["email"]?</p>

<p>Major: <?php echo $_POST["major"]?</p>


</body>

</html>

I'm totally new to PHP, so any help is greatly appreciated!

Your form method should be POST.

您的表单方法应该是POST。

 <form name="information" method="POST" action="action.php" onsubmit="return validate();">

And add a name to the submit button:

并在提交按钮中添加一个名称:

<input type="submit" value="Process" name="submit" />

Also, you could add this if condition:

此外,您可以添加以下条件:

<?php 
  echo "<pre>";
  print_r($_POST);   // Check if you're getting any POST data
  echo "</pre>";
?>

<?php if (isset($_POST['name'])) { ?>

 <h1>Form data</h1>
 <p>Name: <?php echo $_POST["name"]; ?> 
 </p>
 <p>Email: <?php echo $_POST["email"]; ?> 
 </p>
 <p>Major: <?php echo $_POST["major"]; ?> 
 </p>

<?php } ?>

Hope this helps.

希望这可以帮助。
