That does look interesting, thanks for that information.
That said, it looks like she's trying to pull post information in to her sidebar.
I am looking to input something unique that I put in to the sidebar of the posts instead.
So, if it's post 1, then I want to display A on the sidebar.
If it's post 2, then I want to display B on the sidebar
If it's category 3, then I want to display C on the sidebar, etc.
(By unique, I mean A, B and C is code that I have from outside of my site itself; like code to link to other sites or merchandise to buy that is customized to that specific page, etc.)
I'm not sure that the description of what her code is doing will work for what I'm looking to do?
I really hope to find the code, otherwise I guess I'm going to take all of my posts, make them in to pages instead, and never use posts or categories since I know my method works to customize pages. It just means redoing a whole ton of links.
I hope I don't have to do that?
(Please note I'm looking to avoid using plug-ins - I have my reasons.)
