As you all know there are different "Who's Online"-type sections on several different pages on the board. The feature proper, on the board index, and the different "who's viewing this board/page" ones as well. I was looking into trying to make them appear, when they appear (I'm not talking about putting the one on the BoardIndex on every page! They would appear on the pages they do now), into the header, above where the link tree is now.
I'm trying to figure out the most efficient way to do it. It'd be nice if there was some way of calling a function and having the other PHP file that's pulled up provide it, but I don't know if it works that way. If anyone has any advice for a solid (and secure) way to perform this process, I'd greatly appreciate it.
