phpBB offers some functions for getting user information. Two particularly useful ones are get_userdata() and auth(). If you do a lot of work with users, you will find the get_userdata() function immensely helpful. You can pass either the username or user ID number of the user whose data you wish to retrieve to the function. phpBB will figure it out and return a value. If you wish, you can also pass a second, optional parameter called force_str. If you pass true in as the second parameter, it will force a username check. If the user ID or username was found, the function will return the user s data. If the user does not exist, the function returns false. You are also able to retrieve permissions for a user or group by using the auth() function, which is the programming interface to the permissions system. This can help you write hacks that are dependent on the rights of a user. auth() takes four parameters:

For example, Listing 11-6, which comes from viewtopic.php, gives an example of phpBB checking permissions on a topic. Listing 11-6. Using auth() to Check Topic Permissions, from viewtopic.php // // Start auth check // $is_auth = array(); $is_auth = auth(AUTH_ALL, $forum_id, $userdata, $forum_topic_data); if( !$is_auth['auth_view'] || !$is_auth['auth_read'] ) { if ( !$userdata['session_logged_in'] ) { $redirect = ( isset($post_id) ) POST_POST_URL . "=: $post_id" POST_TOPIC_URL . "=$topic_id"; $redirect .= ( isset($start) ) "&start=$start" : ''; redirect(append_sid("login.$phpEx redirect= viewtopic.$phpEx&$redirect", true)); }

CHAPTER 11 MODIFYING PHPBB
$message = ( !$is_auth['auth_view'] ) $lang['Topic_post_not_exist'] : sprintf($lang['Sorry_auth_read'], $is_auth['auth_read_type']); message_die(GENERAL_MESSAGE, $message); } // // End auth check // In Listing 11-6, the first two lines do predefined queries to the database to see what kind of authorization level is available for the objects requested. In this case, the queries are sending the ID number of the forum you are in (as it corresponds to the database), the $userdata variable containing all pertinent information about the current user (logged in or anonymous), and additional information about the data in the topic (such as the topic s database ID number, so it can determine if the topic is locked, for example). Next, the script checks to see if the current user s permissions permit the user to read or view topics in the forum. If one of these checks fails, phpBB then looks to see if a session is logged in on the computer. If this is the case, phpBB spits out an Access Denied error message and ends the script. If not, phpBB will redirect the user to the login screen, where the user has the opportunity to enter the username and password of a user with proper permissions to the forum.
