[SOLVED] Pagination ?

Clinton · January 4, 2009

I know very little about pagination. I was having problems with a different script earlier and tried another one. This script works up until the point you click on another link.

The link is "http://localhost/project/search.php?page=2" but all it does is display a blank page, properly formatted. No information, no results, no nothing. How do I fix this?

<?php
session_start();
include 'connect/project.htm';

$smajor = $_POST['major'];
?>


<html>
<head>
<title>Intranet - <?php echo $smajor ?> Workings</title>

I think I figured it out. I think it has to do with $smajor = $_POST['major']; which is called at the very beginning. When you go to the second page there is nothing posted so it's not calling that.

Perhaps setting this as a session variable?

Clinton · January 4, 2009

I FIGURED IT OUT!!!!!!!!! YES! It was exactly what I thought it was. 5 hours later. LoL

if (!$_POST['major'] == NULL)
{unset($_SESSION['smajor']);
 $_SESSION['smajor'] = $_POST['major'];
 $smajor = $_POST['major'];
}
else $smajor = $_SESSION['smajor']
