Add Default Taxonomies to a Custom Post Type

Topic: WordPress

Published on Updated

In WordPress, the basic taxonomies, categories and tags, are only set up to be used on the default post type. If you want to add them to a custom post type you’ve created, you can do so by adding category and/or post_tag to the taxonomies array element in the post type’s argument array.
