Is there anyway to add the time read to this?

Excellent Johannes! I will install when I get home tonight ... :D

Code:

<if condition="in_array($bbuserinfo['usergroupid'], array( 5, 6, 7))">

<!-- who viewed this thread code-->

</if>

...will restrict viewing only to admins and mods. Add other usergroups at your discretion.

Installed, and thanks. :up:

Okay, replies like that, especially from a moderator, just irk the hell out of me. If you're going to slap down my solution you'd better have one handy that works, or at least tell me why mine won't. If a template condition doesn't render then no query is executed. If you prove me wrong I'll gladly apologize.

Simple, this is in general how things work (and don't see it as slapping down, just don't always have the time to give a more extended asnwer):
- PHP Script is run
- Logic of the script is followed
- Script will retrieve all needed information from the database and place the information in variables.
- Once all info is available, the script will evaluate a template, in which the variables get replaced by their values.

As you see a condition placed in a template, only effect what is displayed, not what is retrieved from the database.

I can't give you an alternative solution, because i never even looked into this hack. But if you want to improve performance by excluding guests, you will have to edit the PHP-script to make that it will not query the database if a guest is viewing.

just showing my appriciation for the hack, installed! thank you for making it.
