There is a function at Admin->Info that shows the active sessions.
If you access the link, then click "Scalars" it should show the
You could pretty easily modify the tag it to read the session and send out
the user name as a link instead....
If you have a very busy catalog and you think the function will be
frequently accessed, you might instead have each page access update a
small database table.
[if session logged_in]
key="[data session username]"
You could make it more efficient, probably, by using a TIMESTAMP.
Then a simple query:
[tmp 30min][time adjust="-30 minutes"]%Y%m%d%H%M%S[/time][/tmp]
[query list=1 sql="
SELECT * from logged_in
WHERE active_time >= '[scratch 30min]'
ORDER BY active_time DESC
[loop-code] --> [loop-param active_time]
There are other possible ways to make it even lower-overhead; for instance
symlinking the username field to the session file and having a cron
job manage the updating on an every-minute basis.
