Session Problems.

[fulco]

I am working on my first membership system and I am having problems getting my session variables to pass.

Here's a chunk of my first set of code.

<?
/* Check User Script */
session_start();  // Start Session

include 'db.php';
// Conver to simple variables
$username = $_POST['username'];
$password = $_POST['password'];

if((!$username) || (!$password)){
	echo "Please enter ALL of the information! <br />";
	include 'login_form.html';
	exit();
}

// Convert password to md5 hash
$password = md5($password);

// check if the user info validates the db
$sql = mysql_query("SELECT * FROM users WHERE username='$username' AND password='$password' AND activated='1'");
$login_check = mysql_num_rows($sql);

if($login_check > 0){
	while($row = mysql_fetch_array($sql)){
	foreach( $row AS $key => $val ){
		$key = stripslashes( $val );
	}
		// Register some session variables!
		session_register('first_name');
		$_SESSION['first_name'] = $first_name;
		session_register('last_name');
		$_SESSION['last_name'] = $last_name;
		session_register('email_address');
		$_SESSION['email_address'] = $email_address;
                session_register('username');
		$_SESSION['username'] = $username;
		session_register('user_level');
		$_SESSION['user_level'] = $user_level;


	mysql_query("UPDATE users SET last_login=now() WHERE userid='$userid'");

	header("Location: login_success.php");
}
} else {
//<--Snip-->

I then try to use this in my login_success.php page.

//<--Snip-->

<?
printf ("Name:%s<br>", $_SESSION['username']);

?>

//<--Snip-->

<?
if($user_level == 0){
echo "User Level: Gamma 1";
}
if($_SESSION['user_level'] == 1){
echo "User Level: Alpha 1";
}
if($_SESSION['user_level'] == 2){
echo "User Level: Delta 1";
}
if($_SESSION['user_level'] == 3){
echo "User Level: Delta 2";
}
if($_SESSION['user_level'] == 4){
echo "User Level: Theta 1";
}
if($_SESSION['user_level'] == 5){
echo "User Level: Theta 2";
}
if($user_level == 6){
echo "User Level: Omicron 1";
}
?>
//<--Snip-->

Can anyone help point out what I'm doing wrong? Thanks for your help. If you need more info let me know.

Quote from PHP.net

If you are using $_SESSION (or $HTTP_SESSION_VARS), do not use session_register()

I'm having a problem understanding where the variables are that you want to register.

ie: $first_name.. where is this variable defined?

I'm guessing... answer my question above and I could help a littler better : )

$first_name = $row['first_name'];
session_register("first_name");

if (session_is_registered("first_name")) {
 echo "Success! First Name: " . $first_name;
} else {
 echo "Session Failed :(";
}
