Unregistered post types

If a post type is not registered yet on this site, Zelvigo shows a confirmation prompt. Post types already generated in Zelvigo are accepted automatically — useful when building a plugin package before the CPT exists on the live site.

After generating

Copy the PHP and add it to your plugin. Register taxonomies on the init hook alongside your CPT.
