I've traversing the net for a solution to this, but I simply cannot seem to get there.
I use the (top) categories for page titles, and the various pages only display posts from their respective categories. I'd like to - on single post pages have child categories listed and clickable beneath the (top category) title, and on archive pages have the child categories listed underneath the post title:
single.php:
[h2](TOP CATEGORY TITLE)
[h3](CHILD CATEGORIES)
(POST TITLE, etc.)
category.php:
[h2](TOP CATEGORY TITLE)
(POST TITLE)
[h3](CHILD CATEGORIES)
(POST + METADATA, etc.)
I can't understand why this should be so difficult. Granted, I'm a complete noob with PHP, but it doesn't seem too infeasible to me...?
