//Start validation proccess

if ($_POST['username'] == NULL )  
{
echo 'Username Field Empty, Please go back!';
exit;
}

if ($_POST['email'] == NULL ) 
{
echo 'Email Field Empty, Please go back!';
exit;
}

?>

<?php 
include("../include/footer.php");
?>

The problem is that even if I do enter a username, I still get message syaing I need to fill it in.

Cheers

In the register.php

    <td width="439"><form id="register" action="reg_process.php" method="get">
// Should be
    <td width="439"><form id="register" action="reg_process.php" method="post">

Proper validation:

<?php


if (empty($_POST['username'])||!isset($_POST['username'])
{
echo 'Username Field Empty, Please go back!';
exit;
}

if (empty($_POST['email'])||!isset($_POST['email']))
{
echo 'Email Field Empty, Please go back!';
exit;
}
?>
