CodeIgniter and Wordpress Integration - wordpress

Question

I have a forum developed with CodeIgniter. And I have my website, powered by Wordpress.
Basically what I'm looking to do is when a user registers on the forums, it adds those details to the Wordpress user table, so they're registered on both.
My code for the forum...
/**
* Create new user record
*
* #param array
* #param bool
* #return array
*/
// username email password last_ip key
function create_user($data)
{
$sql = "INSERT INTO users (username,
email,
password,
last_ip,
created,
activated
) VALUES (
?, ?, ?, ?, ?, ?
)";
$this->db->query($sql, array(
$data['username'],
$data['email'],
$data['password'],
$data['last_ip'],
date("Y-m-d H:i:s", utc_time()),
$data['activated']
));
if ($user_id = $this->db->insert_id()) {
$this->create_profile($user_id);
return TRUE;
}
return FALSE;
}
function activate_user($username)
{
$this->db->query("UPDATE users SET activated = 1 WHERE username = ?", $username);
return $this->db->affected_rows();
}
and the Wordpress register class...
/**
* Handles registering a new user.
*
* #param string $user_login User's username for logging in
* #param string $user_email User's email address to send password and add
* #return int|WP_Error Either user's ID or error on failure.
*/
function register_new_user( $user_login, $user_email ) {
$errors = new WP_Error();
$sanitized_user_login = sanitize_user( $user_login );
$user_email = apply_filters( 'user_registration_email', $user_email );
// Check the username
if ( $sanitized_user_login == '' ) {
$errors->add( 'empty_username', __( '<strong>ERROR</strong>: Please enter a username.' ) );
} elseif ( ! validate_username( $user_login ) ) {
$errors->add( 'invalid_username', __( '<strong>ERROR</strong>: This username is invalid because it uses illegal characters. Please enter a valid username.' ) );
$sanitized_user_login = '';
} elseif ( username_exists( $sanitized_user_login ) ) {
$errors->add( 'username_exists', __( '<strong>ERROR</strong>: This username is already registered, please choose another one.' ) );
}
// Check the e-mail address
if ( $user_email == '' ) {
$errors->add( 'empty_email', __( '<strong>ERROR</strong>: Please type your e-mail address.' ) );
} elseif ( ! is_email( $user_email ) ) {
$errors->add( 'invalid_email', __( '<strong>ERROR</strong>: The email address isn’t correct.' ) );
$user_email = '';
} elseif ( email_exists( $user_email ) ) {
$errors->add( 'email_exists', __( '<strong>ERROR</strong>: This email is already registered, please choose another one.' ) );
}
do_action( 'register_post', $sanitized_user_login, $user_email, $errors );
$errors = apply_filters( 'registration_errors', $errors, $sanitized_user_login, $user_email );
if ( $errors->get_error_code() )
return $errors;
$user_pass = wp_generate_password( 12, false);
$user_id = wp_create_user( $sanitized_user_login, $user_pass, $user_email );
if ( ! $user_id ) {
$errors->add( 'registerfail', sprintf( __( '<strong>ERROR</strong>: Couldn’t register you... please contact the webmaster !' ), get_option( 'admin_email' ) ) );
return $errors;
}
update_user_option( $user_id, 'default_password_nag', true, true ); //Set up the Password change nag.
wp_new_user_notification( $user_id, $user_pass );
return $user_id;
}
I don't need all the extra bumph of the Wordpress class, I'm just looking for a barebones forum values addition to the Wordpress user table.
Any help?

Two database configs will be required in your codeigniter config file:
$db['wordpress']
$db['default'] //priority
To use the wordpress DB assign it a var in your main controller.
$this->wordpress_db = $this->load->database('wordpress', TRUE);
//Normal query
$this->db->query();
//wordpress Query
$this->wordpress_db->query();
The rest should become obvious
