I’d like to be able to have categories of a custom post type, how do you set this up?
update
I want to keep the default categories for regular blog posts, but a separate set of categories just CPT.
How do you add categories to custom post types in WordPress?
You need to add
'taxonomies' => array('category')in yourregister_post_type()function.register_post_type()register_taxonomy()register_taxonomy_for_object_type()You have to register a taxonomy using register_taxonomy or register_taxonomy_for_object_type. The you can use wp_insert_term to insert values for that taxonomy.
