Not to me it wasn't....

I ended up with something that works finally!

Code:

<?php

class Register extends Controller {

    function register()
    {
        parent::Controller();
        $this->load->helper('form');
        $this->load->helper('url');    
        $this->load->library('form_validation');
    }
    
    function index()
    {
        $this->load->view('header');
        redirect('register/register_form');
        $this->load->view('footer');
    }
    function register_form() {
        $this->form_validation->set_rules('username', 'Username', 'callback_check_username');
        $this->form_validation->set_rules('password', 'Password', 'required|matches[passconf]');
        $this->form_validation->set_rules('passconf', 'Password Confirmation', 'required');
        $this->form_validation->set_rules('email', 'Email', 'callback_check_email');
        if ($this->form_validation->run() == FALSE)
        {
        $this->load->view('header');
        $this->load->view('register_form');
        $this->load->view('footer');        }
        else
        {
            //Register the Player
            $this->register_member();
            //Show the Next Page
            redirect('register/success');
        }
    }
    //
    function check_username($str) {
        //Does the Username Exist?
        $query = $this->db->get('players');
        foreach ($query->result() as $row):
        $username_exist = $row->username;
        if ($str == $username_exist)
        {
            return FALSE;
            $this->form_validation->set_message('username', 'Email Invalid');

        }
        else
        {
            return TRUE;
        }
        endforeach;
    }
    //Does the Email Exist?
    function check_email($str) {
        //Does the Username Exist?
        $query = $this->db->get('players');
        foreach ($query->result() as $row):
        $email_exist = $row->email;
        if ($str == $email_exist)
        {
            return FALSE;
            $this->form_validation->set_message('email', 'Email Invalid');

        }
        else
        {
            return TRUE;
        }
        endforeach;
    }
    //Register the New User Please :)
    function register_member() {
            $username = $_POST['username'];
            $password = $_POST['password'];
            $email = $_POST['email'];
            $this->db->insert('players', $_POST);
    }
    //
    function success() {
        $this->load->view('header');
        $this->load->view('register_success');
        $this->load->view('footer');
    }
}

?>

Not the most secure or pretty code ever but it works for my first try...thanks for the help everyone. I'll check out that thread.
