PHP Auth verification system (need some help)


Recommended Posts

Ok So the main purpose of this is:


1). User has to grab a OTP from the generator (work's)

2) the OTC updates in the database field (work's) via the person's user_email

3). it sends an email containing the OTP


what it is not doing is, when they go and login, it just keeps saying invalid login credentials.


I'm pasting my code below to see if anyone can help me out here. this is still a work in progress.



do_login.php (not working here) Keep's saying invalid password.


if(empty($_POST)) exit;

include 'config.php';

// declare post fields

$post_user_email = trim($_POST['user_email']);
$post_password = trim($_POST['authcode']);

$post_autologin = $_POST['autologin'];

if(($post_user_email == $config_email) && ($post_password == $config_password))
$_SESSION['Site-Key'] = $config_email;

// Autologin Requested?

if($post_autologin == 1)
$password_hash = md5($config_password); // will result in a 32 characters hash

setcookie ($cookie_name, 'usr='.$config_email.'&hash='.$password_hash, time() + $cookie_time);

echo '<div id="error_notification">The submitted login info is incorrect.</div>';





require_once 'config.php';
