PHPBB3 Forum External Registration Problem

Question

I'm trying to implement a external registration form in my website to directly create an account in my PHPBB Forum. I've inserted the login method with ease, but the registry is completly broken.

In my tests, a special code I found is inserting a person with fixed text parameters in PHP, but when I try to parse the information via form, it doesn't work and I made some tests with AJAX to make sure the infos were being sent to the PHP file.

Original Code:

<?php
define('IN_PHPBB', true);
$phpbb_root_path = './';
$phpEx = substr(strrchr(__FILE__, '.'), 1);
include($phpbb_root_path . 'common.' . $phpEx);


// Start session management
$user->session_begin();
$auth->acl($user->data);
$user->setup();

require($phpbb_root_path .'includes/functions_user.php');

$username = request_var('username', '', true);
$password = request_var('password', '', true);
$email    = request_var('email', '', true;)



$username = 'testUser';
$password = 'PassWord'; // Dont encrypt the password!
$email = '[email protected]';


// Check for unique username otherwise it will throw an error or might be blank page

$user_row = array(
'username' => $username,
'user_password' => md5($password),
'user_email' => $email,
'group_id' => 2, #Registered users group
'user_timezone' => '1.00',
'user_dst' => 0,
'user_lang' => 'en',
'user_type' => '0',
'user_actkey' => '',
'user_dateformat' => 'd M Y H:i',
'user_style' => 1,
'user_regdate' => time(),
);
$phpbb_user_id = user_add($user_row);
?>

// IP address of the user stored in the Database.
$user_ip = $user->ip;

My Revised Code:

<?php
define('IN_PHPBB', true);
$phpbb_root_path = './';
$phpEx = substr(strrchr(__FILE__, '.'), 1);
include($phpbb_root_path . 'common.' . $phpEx);


// Start session management
$user->session_begin();
$auth->acl($user->data);
$user->setup();

require($phpbb_root_path .'includes/functions_user.php');

$username = request_var('username', '', true);
$password = request_var('password', '', true);
$email    = request_var('email', '', true;)


// Check for unique username otherwise it will throw an error or might be blank page

$user_row = array(
'username' => $username,
'user_password' => md5($password),
'user_email' => $email,
'group_id' => 2, #Registered users group
'user_timezone' => '1.00',
'user_dst' => 0,
'user_lang' => 'en',
'user_type' => '0',
'user_actkey' => '',
'user_dateformat' => 'd M Y H:i',
'user_style' => 1,
'user_regdate' => time(),
);
$phpbb_user_id = user_add($user_row);
?>

// IP address of the user stored in the Database.
$user_ip = $user->ip;

My HTML Registration Form:

<div id="page-body">
        

<script type="text/javascript">
// <![CDATA[
    /**
    * Change language
    */
    function change_language(lang_iso)
    {
        document.forms['register'].change_lang.value = lang_iso;
        document.forms['register'].submit.click();
    }

    

// ]]>
</script>
