has_category() WP 3.1.0
Checks whether the current or specified post has at least one of the specified categories.
Works for category taxonomy only. Use has_term(), when you need to check a post for another taxonomy.
If no categories are provided for comparison, the function will check whether at least one category is assigned to a post.
The given categories are checked against the post's categories' term_ids, names and slugs. Categories given as integers will only be checked against the post's categories' term_ids.
If no categories are given, determines if post has any categories.
