auto-creating a forum?

[Wired1]

Well, I got it to work, except that Display Order = 0 and every setting except for Apply This Password to Child Forums is set to 0. This setup is not the default. If I'm reading it correct, build_forum_permissions(); is supposed to use the defaults? I'd like for it to use the defaults of the site, or the forum it is a sub-forum of. Here's the code so far:

PHP Code:

require_once('./global.php'); 
require_once('./includes/functions_misc.php'); 
require_once('./includes/adminfunctions_forums.php'); 
require_once('./includes/adminfunctions.php');

$foruminfo = array( 
        'parentid' => 10, 
        'title' => 'Some foobar title', 
        'description' => 'Some foobar description' 
); 

$parentlist = fetch_forum_parentlist($foruminfo['parentid']); 
$DB_site->query(fetch_query_sql($foruminfo, 'forum')); 

$forumid = $DB_site->insert_id(); 
$DB_site->query(" 
        UPDATE " . TABLE_PREFIX . "forum 
        SET parentlist='" . addslashes("$forumid,$parentlist") . "', 
        childlist = '$forumid,-1' 
        WHERE forumid = $forumid 
"); 

build_forum_permissions();
