I'm at my wits end on this one...
On my laptop, when I'm testing the code, everything works fine. However, when I move it to the server, it stops working...very frustrating. Here's the senario:
Laptop: Windows XP, IIS 5.1, php 5.0.3 build 2600
Server: Windows XP, Apache/1.3.23, php 4.1.1 build 2195
Page 1: Enter Info
After a person enters some mundane data, clicks submit, and the form is submitted. The data is validated, and is sent to page 2 for the confirmation.
Page 2: Confirmation
This displays what the user entered, and gives them the opportunity to change something. Once everything has been looked over and okayed, the user clicks 'Confirm', and page 2 will update the database, etc, and then refresh the page with a message stating that the info has been accepted. Then, the user clicks a link to take them back to page 1.
Here's the problem: Once the code is on the server, the session variables DO NOT get reset! Could it be a problem with the unset code? Could it be a PHP version problem? I have no idea...and ANY help is greatly appreciated!
Here's page 1:
<?php
session_start();
header("Cache-control: private"); //IE 6 Fix
/* Initialize variables used in the page */
if (isset($_POST['name'])) {
$name = $_POST['name'];
}
else if (isset($_SESSION['name'])) {
$name = $_SESSION['name'];
}
else {
$name = NULL;
}
if (isset($_POST['id'])) {
$id = $_POST['id'];
}
else if (isset($_SESSION['id'])) {
$id = $_SESSION['id'];
}
else {
$id = NULL;
}
if (isset($_POST['submit'])) {
$submit = $_POST['submit'];
}
else {
$submit = NULL;
}
// This is set for the first time into the page
$worked = NULL;
/* If the form is submitted, process the registration */
if (isset($submit)) {
//$worked = validate_page_1($id, $name);
$worked = true;
}
if ($worked) {

// If the function worked, set sessions variables and go to next page
$_SESSION['name'] = $name;
$_SESSION['id'] = $id;

Works great in test, but as soon as it gets moved to the server, the unset for the session variables fail...
Thanks in advance for the help!
