Joomla sitemap fun!
Attention! Nerd alert! This post is almost strictly intended as a write-up of some recent web code stuff I did, so if you're here for my normal ridiculous stream of cat / chocolate / kid pichurs or rantings, you may be left wanting:
I haven't posted code here in ages. That's a shame, actually, because I love sharing my code so people can school me on how much better it could be.
Thus, I submit for your approval / derision / amusement / amazement my latest bit of brilliance. I needed something to generate a sitemap for a my latest client Joomla site. I looked through all the available plugins and they either didn't work with Joomla 1.5, or didn't support our most important extension (the amazing EventList). So, I adapted some code I wrote a while back for my old blog software.
All up, I'm very happy with the results. It uses mainly Joomla built-ins -- something I always try to do when possible -- and thus should work pretty much as a drop-in on any Joomla 1.5 site. Regrettably, I had to resort to actually pulling stuff directly out of the database -- for the EventlList stuff -- but I wasn't left with much choice, unfortunately.
A huge shout-out to Christoph Lukes, specifically and the whole team over at http://schlu.net for their hard work on EventList, and for the code for the xmap extension, from which I was able to get enough information to get my EventList sitemap hack working.
Without further Ado, the code:
