Hey all,
I was wondering if anyone could explain to me why I can't seem to maintain a session using
PHP 4.1.2 on my NT4 server. I am don't have any problems on my W2K/IIS5 or Linux machine.
What I am doing is allowing my users to log on to the site at any time, and then being returned to
the page that they logged in from. This isn't the problem. The problem is on the NT4/PHP4.1.2
machine when I click on a link to go to another page their login information is lost, almost as if
they logged out. Here is the validation code that I am currently using:
[auth.inc]
<?php
function validateUser() {
$users = file("includes/users.txt");
if(!isset($_SESSION['logged_in'])) $_SESSION['logged_in'] = FALSE;
if(!isset($_SESSION['log_attempt'])) $_SESSION['log_attempt'] = FALSE;
if(!isset($_SESSION['valid_user'])) $_SESSION['valid_user'] = "";
if(!isset($_SESSION['email'])) $_SESSION['email'] = "";
if(!isset($_REQUEST['phpsessid'])) {
if(empty($_POST['email']) || empty($_POST['passwd'])) {
$email = "";
$pass = "";
} else {
$email = $_POST['email'];
$pass = $_POST['passwd'];
$_SESSION['log_attempt'] = TRUE;
}
// replace with SQL query when db is instated
foreach($users as $login) {
list($user,$passwd,$fname,$lname) = explode("|",$login);
if($user==$email && $passwd==md5($pass)) {
$_SESSION['logged_in'] = TRUE;
$_SESSION['valid_user'] = $fname." ".trim($lname);
$_SESSION['email'] = $email;
}
}
}
return($_SESSION['logged_in']);
}
?>
Once again, it works fine on the W2K/IIS5 and Linux box, so that is why I am having problems
isolating the problem. Maybe it's just my logic and a fresh pair of eyes would help looking at
this.
Thanks for all your help,
