I plan on having many categories/subcategories in 2.8 as I will be hacking WP up to more of a searchable directory CMS. Basically, every US State is a category. Rather than key in 50+ states, I have a php script setup that calls this code:
Its repeated with each state (dynamically created)
What include files do I need to call before I can do this? I searched everywhere but can't seem to find it.
