I'm trying to use SimplePie RSS. It has lots of annoying picky behavior. To include more than one set of RSS feeds on a page I have to use a URL for one of them - don't ask me why...
This works:
<? include 'http://hardcodedurl.com/feeds/feeds.php'; ?>
To avoid hardcoded URLs I'd like to use this, but this doesn't work:
<? include WP_SITEURL.'/feeds/feeds.php'; ?>
Also tried it with WP_HOME. Nothing works. Why not? Anything else I could try?
What are the WP_THINGS called? They're not template tags, are they? Is there a reference list of them somewhere?
