More if condition help - search and searchid

I saw an old post from brian and I decided to try it out on my site.:

Code:

<if condition="!(
(THIS_SCRIPT == 'index') OR
(THIS_SCRIPT == 'login') OR
(THIS_SCRIPT == 'register') OR
(THIS_SCRIPT == 'usercp') OR
(THIS_SCRIPT == 'private') OR
(THIS_SCRIPT == 'subscription') OR
(THIS_SCRIPT == 'payments') OR
(THIS_SCRIPT == 'newthread') OR
(THIS_SCRIPT == 'newreply') OR
(THIS_SCRIPT == 'memberlist') OR
(THIS_SCRIPT == 'online') OR
(THIS_SCRIPT == 'member') OR
(THIS_SCRIPT == 'profile') OR
(THIS_SCRIPT == 'faq') OR
(THIS_SCRIPT == 'sendmessage') OR
(THIS_SCRIPT == 'calendar') OR
((THIS_SCRIPT == 'calendar') AND $_REQUEST['do'] == 'add') OR
((THIS_SCRIPT == 'search') AND $_REQUEST['searchid'] == '') OR
(THIS_SCRIPT == 'THIS_SCRIPT'))">

Everything seems to be working fine...besides when I click NEW POSTS. I get the code that shouldn't be showing up on that list above. I figure it had to do with the searchid part of the code.

Please help

what exactly are you tyring to do?

I'm working with RR's and ads basically. Go here:
Graphics Tutorials, Signature Showoff, Web Graphics Design, and Graphics Help! - Layered GFX Forums

I want it so when you are on the scripts mentioned above, you have the leaderboard ads, but when you go into a category/sub-forum, it gets replaced with 2 ads on the left and RR's on the right. Sort of like vBulletin-faq I guess. So I have it like that...the only thing that is screwing up is when I search something (ie using NEW POSTS feature).

I know this thread is old - does this "OR" syntax still work? I just tried it out and it doesn't appear to.

I'm trying to display different divs based on the script being run - nested if conditions work, but it seems pretty clunky.

Oops - my bad. I wasn't paying attention to the not equal "!" at the top of the code in the earlier post. This works fine.

This code works great. Can anyone tell me what this part:

Code:

THIS_SCRIPT == 'THIS_SCRIPT'

is checking?

that checks for any script that has a defined value of THIS_SCRIPT as a literal. Some mods used to use that.
