Number of users browsing current forum

This is a really simple hack that displays the number of users browsing the current forum along
with the list of users.

It requires no template changes.

In forumdisplay.php

find:

PHP Code:

if ($showforumusers) {
        $datecut = $ourtimenow - $cookietimeout;
        $browsers = '';
        $comma = '';
        $forumusers = $DB_site->query("SELECT username, invisible, userid
                                                FROM user
                                                WHERE  inforum = $foruminfo[forumid]
                                                        AND lastactivity > $datecut
                                                        AND lastvisit <> lastactivity");
        while ($forumuser = $DB_site->fetch_array($forumusers)) {
                if ((!$forumuser['invisible'] or $bbuserinfo['usergroupid'] == 6) and $bbuserinfo['userid'] != $forumuser['userid']) {
                        $userid = $forumuser['userid'];
                        $username = $forumuser['username'];
                        if ($forumuser['invisible'] == 1) { // Invisible User but show to Admin
                                $invisibleuser = '*';
                        } else {
                                $invisibleuser = '';
                        }
                        eval("\$browsers .= \"".$comma.gettemplate('forumdisplay_loggedinuser')."\";");
                        $comma = ', ';
                }
        }
        // Don't ask the DB for the user that is viewing the page as they wouldn't be here if they weren't! DOH!
        // This way our query up above can hit the inforum index so don't change unless you know what you are doing.
        if ((!$bbuserinfo['invisible'] or $bbuserinfo['usergroupid'] == 6) and $bbuserinfo['userid'] <> 0) {
                $userid = $bbuserinfo['userid'];
                $username = $bbuserinfo['username'];
                if ($bbuserinfo['invisible'] == 1) { // Admin is invisible but show himself to himself, get it!
                        $invisibleuser = '*';
                } else {
                        $invisibleuser = '';
                }
                eval("\$browsers .= \"".$comma.gettemplate('forumdisplay_loggedinuser')."\";");
        }
        if ($browsers) {
                if (!$moderatedby) {
                        $onlineusers = "<br>";
                }
                eval("\$onlineusers .= \"".gettemplate('forumdisplay_loggedinusers')."\";");
        }
} 

And replace it with:

PHP Code:

if ($showforumusers) {
        $datecut = $ourtimenow - $cookietimeout;
        $browsers = '';
        $comma = '';
        $usercount = 0;
        $forumusers = $DB_site->query("SELECT username, invisible, userid
                                                FROM user
                                                WHERE  inforum = $foruminfo[forumid]
                                                        AND lastactivity > $datecut
                                                        AND lastvisit <> lastactivity");
        while ($forumuser = $DB_site->fetch_array($forumusers)) {
                if ((!$forumuser['invisible'] or $bbuserinfo['usergroupid'] == 6) and $bbuserinfo['userid'] != $forumuser['userid']) {
                        $userid = $forumuser['userid'];
                        $username = $forumuser['username'];
                        if ($forumuser['invisible'] == 1) { // Invisible User but show to Admin
                                $invisibleuser = '*';
                        } else {
                                $invisibleuser = '';
                        }
                        eval("\$browsers .= \"".$comma.gettemplate('forumdisplay_loggedinuser')."\";");
                        $comma = ', ';
                        $usercount++;
                }
        }
        // Don't ask the DB for the user that is viewing the page as they wouldn't be here if they weren't! DOH!
        // This way our query up above can hit the inforum index so don't change unless you know what you are doing.
        if ((!$bbuserinfo['invisible'] or $bbuserinfo['usergroupid'] == 6) and $bbuserinfo['userid'] <> 0) {
                $userid = $bbuserinfo['userid'];
                $username = $bbuserinfo['username'];
                if ($bbuserinfo['invisible'] == 1) { // Admin is invisible but show himself to himself, get it!
                        $invisibleuser = '*';
                } else {
                        $invisibleuser = '';
                }
                $usercount++;
                eval("\$browsers .= \"".$comma.gettemplate('forumdisplay_loggedinuser')."\";");
        }
        if ($browsers) {
                $browsers = "<b>($usercount users)</b> $browsers";
                if (!$moderatedby) {
                        $onlineusers = "<br>";
                }
                eval("\$onlineusers .= \"".gettemplate('forumdisplay_loggedinusers')."\";");
        }
} 

You can see a sample of this at my site: http://www.ls1.com/forums/index.php

It would be better if the number could be showen on the main forum page

[Floris]

I had the same idea :P

So, this only adds the number of people right? Because vB 2.2.5 already has 'Users browsing this forum: nick1, nick2, ..' by default.

I will make this tonight if I am not to lazy :P

Yes, it adds the number of people to the list.

Like this:

(Users Browsing this Forum: (11 users) mrgto*, Mikesbird, ghetto808, INSSANE, 1BADFIREHAWK, oxide, 00camaroSS, TGrits10, Big Spanky, Amuka, Zed*)

[RDX1]

i dont get what this hack does

[Zzed]

Look at the bold text in my previous reply.

[TECK]

this is a great hack.. and it doesnt require to add a new field.. however i'm concerned with the extra query? how is the server load doing?

[Zzed]

There is no extra query. The counting is being done within the loop. It should have zero effect on the server.

[yasunari]

I found that it won't count the Guest on the forum?
It would be great if it can count how many guest in each forum :P
