在php中使用后退按钮

I am very new to the world of PHP . The problem that I am facing is with the use of back button . When I click on the back button from page2 to page1 the options which I had selected on page1 is not getting saved . So I need to select all the data once again in page1 . I am using sessions . The funny part is when I use a text box question on page 1 and submit its value to page 2 and then click on back button on page2 the data is being saved . Please take a look into this code I named this file as 1.php

<?php
  session_start();
?>
<html>
<body>
<form action="2.php" method="post">

Name<input type="text" name="name" value="<?php if(isset($_SESSION['name'])) echo $_SESSION['name']; ?>"/>


<input type="submit"  value="next"/>
</form>
</body>
</html>

I named this file as 2.php

<?php
session_start();
$name = $_POST['name'];
session_register('name');

?>
<html>
<body>
<form action="1.php" method="post">

<input type="submit"  value="back"/>
</form>
</body>

The problem is that I do not know how to implement this on the radio buttons . Could you please help me out Thanks in advance

    Try this one,

    1.php

    <?php
  session_start();
?>
<html>
<body>
<form action="2.php" method="post">

Radio1 <input type="radio" name="name" value="radio1" <?php if($_SESSION['name'] == 'radio1') echo "checked='checked'" ?>/><br/>
Radio2 <input type="radio" name="name" value="radio2" <?php if($_SESSION['name'] == 'radio2') echo "checked='checked'" ?>/><br/>
Radio3 <input type="radio" name="name" value="radio3" <?php if($_SESSION['name'] == 'radio3') echo "checked='checked'" ?>/><br/>

<input type="submit"  value="next"/>
</form>
</body>
</html>

    2.php

    <?php
session_start();
$name = $_POST['name'];
$_SESSION['name'] = $name;

?>
<html>
<body>
<form action="1.php" method="post">

<input type="submit"  value="back"/>
</form>
</body>
