How to give back button in php page

tanveer

Hi all,
Me back again with a problem. The best place to find some real help.
I am designing a form using php. Now after a user logs in, the user will be given a form of 4 pages. Now, as I am using session so whenever the user clicks the back button it gives a prompt to refresh page as I just gave the name of the prev page in back button's link. So when I refresh it then gives the preious page without the data.
How to easily back and forth between the form pages?
Hope I made myself clear.

Thanks in advance.

Implemented by me.

In the back button I just used this
<a href="name_of_previous_php_page">Back</a>
And in the Form POST I used GET. Thats it.
So, when I click Back the previously filled data is lost.

Hi tanveer,

In place of <a href="name_of_previous_php_page">Back</a>
use javascript history(). i.e. <a href="JavaScript:history.back();">Back</a>

Thanks,

Hi all:
maindeepak, that won't work, I tried.
I have done something like this:
Posting all data in the same page and everything deciding from that page.

General.php

Code:

<?php
session_start();

if( isset($_POST['submit']) || isset($_POST['submitnext']) )
{

if($_GET['page'] == '1')
{
$_SESSION['page1'] = $_POST;

   if($_POST['submit'] == 'Next')
   {
   header('Location:page2.php');
   }
}
elseif($_GET['page'] == '2')
{
$_SESSION['page2'] = $_POST;
   if($_POST['submitnext'] == 'Next')
   {
   header('Location:page3.php');
   }
   else
   {
   header('Location:page1.php');
   }

}
else
{
$_SESSION['page3'] = $_POST;
   if($_POST['submit'] == 'Prev')
   {
   header('Location:page2.php');
   }
}

}

?>

page1.php

Code:

<?php
session_start();
?>
<form name="page" action="general.php?page=1" method="post">
<table width="50%" border="0" align="center" bordercolor="#0033CC">
<tr>
<td><div align="right" class="style4">name</div></td>
<td><input type="text" name="name" value="<?php echo $_SESSION['page1']['name']; ?>"></td>
</tr>
<tr>
<td><div align="right" class="style4">roll</div></td>
<td><input type="text" name="roll" value="<?php echo $_SESSION['page1']['roll']; ?>"></td>
</tr>
<tr>
<td> </td>
<td> <input type="submit" name="submit" value="Next"></td>
</tr>
<tr>
<td> </td>
<td><div align="right" class="style1">Page-1</div></td>
</tr>
</table>
</form>

Page2.php

Code:

<?php
session_start();
?>

<form name="page" action="general.php?page=2" method="post">
<table align="center" width="50%" border="0">
<tr>
<td><div align="right"><span class="style3">name</span></div></td>
<td><input type="text" name="name" value="<?php echo $_SESSION['page2']['name']; ?>"></td>
</tr>
<tr>
<td><div align="right"><span class="style3">roll</span></div></td>
<td><input type="text" name="roll" value="<?php echo $_SESSION['page2']['roll']; ?>"></td>
</tr>
<tr>
<td> </td>
<td><input type="submit" name="submit" value="Prev">
<input type="submit" name="submitnext" value="Next"></td>
</tr>
<tr>
<td> </td>
<td><div align="right" class="style3">Page-2</div></td>
</tr>
</table>
</form>

page3.php

Code:

<?php
session_start();
?>
<form name="page" action="general.php?page=3" method="post">
<table width="50%" border="1" align="center">
<tr>
<td><div align="right">name</div></td>
<td><input type="text" name="name" value="<?php echo $_SESSION['page3']['name'] ; ?>"></td>
</tr>
<tr>
<td><div align="right">roll</div></td>
<td><input type="text" name="roll" value="<?php echo $_SESSION['page3']['roll']; ?>"></td>
</tr>
<tr>
<td> </td>
<td><input type="submit" name="submit" value="Prev">
</td>
</tr>
<tr>
<td> </td>
<td><div align="right">page-3</div></td>
</tr>
</table>
</form>
