<?php
session_start();
?>
<!DOCTYPE html>
<html>

<head>
  <title>Index</title>
  <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
</head>

<body>
  <form name="Index" action="Result.php" method="POST">
    Username: <input type="text" name="username" id="username" autocomplete="off"><br><br> 1. I identify my gender as... <br> &ensp;&ensp;

这是第二页：Test2.php

    <input type="radio" name="age" value="14years">Under 14 years old<br> &ensp;&ensp;
    <input type="radio" name="age" value="15years">15-24 years old<br> &ensp;&ensp;

    <INPUT Type="submit" Value="Proceed" Onclick="Index.action='Test3.php'; return true;">
  </form>
</body>

</html>
<?php
session_destroy();
?>

这是第三页：Test3.php

<?php
session_start();
?>
<!DOCTYPE html>
<html>

<head>
  <title>Test3</title>
  <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
</head>

<body>
  <form action="Result.php" method="POST">
    3. Please specify your ethnicity (race)<br> &ensp;&ensp;
    <input type="radio" name="race" value="chinese">Chinese<br> &ensp;&ensp;
    <input type="radio" name="race" value="malay">Malay<br> &ensp;&ensp;
    <input type="radio" name="race" value="indian">Indian<br> &ensp;&ensp;
    <input type="radio" name="race" value="others">Others<br><br>
    <input type="submit" name="submit" value="Submit">
  </form>
</body>

</html>
<?php
session_destroy();
?>

这是最后一页：Result.php

<?php
session_start();
?>
<html>

<head>
  <title>Result</title>
  <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
</head>

<body>
  Welcome!
  <?php echo $_POST["username"]; ?><br>
  <?php
$gender = $_POST['gender'];
if ($gender == "others")
    echo "<font size='5'>You are not normal</font><br><br>";
else
    echo "<font size='5'>You are normal</font><br><br>";

$age = $_POST['age'];
if (($age == "60years") || ($age == "75years"))
    echo "<font size='5'>You are old man</font><br><br>";
else
    echo "<font size='5'>You are young man</font><br><br>";

$race = $_POST['race'];
if ($race == "others")
    echo "<font size='5'>You are from other race</font><br><br>";
else
    echo "<font size='5'>You are from one of three races</font><br><br>";
?>
</body>

</html>
<?php
session_destroy();
?>

所以，这是四个页面：Index.php - ＆gt; Test2.php - ＆gt; Test3.php - ＆gt; Result.php其中Result.php显示文本框和单选按钮的值（如果... else）。但是当我运行页面时：Index.php转到Test2.php并跳过Test3.php并直接转到Result.php。在Reslt.php中，我得到了这个结果： enter image description here

那么，我该怎么办？我在互联网上搜索并尝试了不同的解决方案，但无法按预期工作。之后，我发现按钮可能存在一些问题。所以，我再次上网寻找合适的解决方案，但未能这样做。现在我不知道该怎么做。对代码的一些解释对我来说将是一个很大的帮助。谢谢;）

Answer 1

您应该在每个页面上获得所需的值，并将它们发布到下一页。

例如，在test2.php，

中

 $username = $_POST["username"];
 $gender = $_POST['gender'];
 <input type="hidden" name="username" id="username" value="<?php echo $username; ?>">
 <input type="hidden" name="gender" id="gender" value="<?php echo $gender; ?>">

undefined index：XAMPP中的名称
