[wp-hackers] if category exists

[Glenn Ansley]

If you're in the admin area you can use the following conditional:
if ( category_exists('category_name') ) { ... }

If you're not in the admin, you just have to reference is_term:
if ( is_term( 'category_name' , 'category' ) ) { ... }

In the second example, "category" needs to remain category, but
category_term is the title of the category your checking for.
