Bit out of my depth here. I'm integrating the forum provider 'phpBB' with my own site and creating an external direct messaging system to phpBB itself. I'm at the stage where I'm receiving this error:
Warning: Cannot modify header information - headers already sent by (output started at /home/treeves4/public_html/pm/pm/new_pm.php:25) in /home/treeves4/public_html/pm/pm/phpBB/includes/functions.php on line 2474
Illegal use of $_REQUEST. You must use the request class or request_var() to access input data. Found in /home/treeves4/public_html/pm/pm/new_pm.php on line 43. This error message was generated by deactivated_super_global.
I've tried $_POST and that also doesn't work. Using $_REQUEST_VAR doesn't raise any errors, but it breaks the script and nothing happens when information is submitted.
The PHP file:
<?php
include('config.php');
define('IN_PHPBB', true);
$phpbb_root_path = './phpBB/';
$phpEx = substr(strrchr(__FILE__, '.'), 1);
include($phpbb_root_path . 'common.' . $phpEx);
// Start session management
$user->session_begin();
$auth->acl($user->data);
$user->setup('ucp');
$_SESSION['userid'] = $user->data['user_id'];
$_SESSION['username'] = $user->data['username'];
?>
<?php
include('config.php');
?>
