Okay I've fixed the segment of code but nothing has changed and it still doesn't work.
This is the code for all the files involved in my login.
I don't know why it doesn't work but I believe the problem is either with the header or membership.php files.
login.php
<?php
require_once 'classes/membership.php';
$membership = new membership();
// If the user clicks the "Log Out" link on the index page.
if(isset($_GET['status']) && $_GET['status'] == 'loggedout') {
$membership->log_user_out();
}
// Did the user enter a password and click submit?
if($_POST && !empty($_POST['pwd'])) {
$response = $membership->validate_user($_POST['pwd']);
} else if(isset($_POST['enter'])){
if($_POST && empty($_POST['pwd'])) {
$response2 = "Please enter a code.";
}
}
?>
