CI + phpBB2 = ...

[eluser]masterix[/eluser]
Hi!

I have following class to integrate my site with forums:

Code:

<?PHP
  if (!defined('BASEPATH')) exit('No direct script access allowed');

  class Integration
  {
    private $userdata;

    public function __construct()
    {
      global $db, $board_config, $phpbb_root_path, $phpEx;
      DEFINE( 'IN_PHPBB', TRUE );

      $phpbb_root_path = 'forum/';

      include($phpbb_root_path . 'extension.inc');
      include($phpbb_root_path . 'common.php' ) ;//.$phpEx);

      if ( !defined( 'IN_PHPBB' ) )
      {
        die( "Hacking attempt!" );
      }

      $userdata_tmp = session_pagestart( $user_ip, PAGE_INDEX );
      init_userprefs( $userdata_tmp );

      $this -> userdata = $userdata_tmp;
     // print_r( $this -> userdata );
    }

    public function get( $key )
    {
      if ( array_key_exists( $key, $this -> userdata ) )
        return $this -> userdata[$key];
      else
        return false;
      //return $this -> userdata;
    }

    public function is_logged()
    {
      return $this -> userdata['session_logged_in'];
    }
  }
?>

This class is in libraries folder and autoloaded by CI.But unfortunately I get some errors like:

A PHP Error was encountered

Severity: Warning

Message: array_merge() [function.array-merge]: Argument #1 is not an array

Filename: forum/common.php

Line Number: 78

I know that CI removes superglobal arrays but I'm pretty sure that it worked few months ago. This line in common.php merges arrays $HTTP_POST_VARS and so on.The controller is very simple:

Code:

<?PHP

  class Test extends Controller
  {
    public function __construct()
    {
      parent::__construct();
    }

    public function index()
    {

      if( $this -> integration -> is_logged() ) echo ":)";
      else echo ":/";

    }
  }

?>

Forum script was modified ( some mods were included ) but I think it isn't the issue.

Thanks in advance for every tip
