I recently took on a project for a small non-profit to give them some functionality in their website. I've done a lot of PHP/JQUERY/AJAX and the lot, but nothing in WordPress. Needless to say I'm a bit stumped.
There wasn't a plugin that I could find that did what this group needed, so I built custom functionality. test.somesite.com/thenewfunctionality.
My question is this - what do I include so that my code shows inside the header / footer / sidebar(s) as though it's part of the site.
I assume getting it to upgrade with the site when changing themes is alltogether different..for this, I'm just looking for it to look cohesive now.
