I've added some changes to a piece of php code in my theme, and I want this code to run only on a certain page in the top level blog in a network.
I have already figured out the "certain page" part of this endeavor, and that works great. Now I'm trying to find a function in wordpress that I can call to determine which blog in the network is currently tickling this code. So far, I'm not finding it.
Can anyone tell me if such a function exists and what it is?
If it's not a matter of calling a function in an "if" statement, then is there another way to do what I want to do?
