I am looking for a way to filter my tag cloud to show just the tags that exist for the category that you are currently in. Here is my hypothetical solution:
1. Use standard tag cloud widget when on front page, archives, search.
2. For category, and single post views, inside the category.php and single_post.php files, load a sidebar with a tag cloud fitlered to only show tags of the current category(ies).
My question is:
All of the tag functions seem to only work on the current post. How do I grab a list of all tags belonging to all the posts in the current category?
