vb.org Archive - how does vb know when a forum is read or unread

from what I can tell, it uses the fetch_forum_lightbulb function in functions_forumlist.php, correct?

But in that function, it doesn't do any user-level checking. For our forum, we have "Database (automatic forum marking)" enabled.

So looking at the code, this is the only real check I see:

Code:

                        if ($vbulletin->options['threadmarking'] AND $vbulletin->userinfo['userid'])

                        {

                                $userlastvisit = (!empty($foruminfo['forumread']) ? $foruminfo['forumread'] : (TIMENOW - ($vbulletin->options['markinglimit'] * 86400)));

                        }



                        if ($lastpostinfo['lastpost'] AND $userlastvisit < $lastpostinfo['lastpost'])

                        {

                                return 'new';

                        }

How does that code at any point check a user's thread read settings? We have thread marking enabled, so shouldn't it be checking the db to see which threads a user has marked as read, and then do a tally of some sort? Am I missing something?

The reason I'm asking is because from what I can tell, that is the function that forumhome uses to get the $forum[statusicon]. I'm using the exact same function for a plugin of mine (tryin to test out something) in order to see whether a forum is read or not. But it's marking them ALL as new, even though only half of them are. It thinks my $userlastvisit is May 19th, how is that?
