I agree with AdRock. I only looked at the login script and saw all kinds of mistakes. You would be better off just following that tutorial and createing your own member system.

here is a decent login script.

[code]
<?php
session_start();
include("db.php");//your database connection file
$username = mysql_real_escape_string(trim($_POST['username']));
$password = mysql_real_escape_string(trim($_POST['password']));

if ((!$username) || (!$password)) {
    if (!$username) {
        $param = "Username, ";
    }
    if (!$password) {
      $param .= "Password, ";
    }
    echo "You did not enter the following required filed(s) " . $param . "please try again.";
    include("your_login_form.html");
    exit();
}
$mdpwd = md5($password);

$sql = sprintf("SELECT COUNT(*) AS `login_match` FROM `your_users_table` WHERE `username`= '%s' AND `password` = '%s'", $username, $mdpwd);
$res = mysql_query($sql) or die(mysql_error());
$login_match = mysql_result($res, 0, 'login_match');

if ($login_match > 0) {
    echo "Your username and password do not match";
    include("your_login_form.html");
    exit();
}
}else{
  $_SESSION['username'] = $username;
  //you could do another sql query here to set more session variables
}
?>
[/code]

When I get a chance I will write a register script for you and post it..

Good Luck,
Tom
