After upgrading to WordPress 2.1, I noticed a lot of things were changed in how output is sent to the themes for lists of things like the category list.
I'm poring over category_template.php for a certain piece of information. I can see the output for the uls and lis, but I need to edit the hyperlink itself, which references another function that I can't do anything with.
$output .= walk_category_tree($categories, $depth, $r);
As far as I can tell, that's the line that outputs the a tags, but the function walk_category_tree() references other functions that I can't find anywhere.
I'm pretty lost here. Where would I look for the hyperlink output?
