Add Already Registered Custom Taxonomy to Custom Post Type in WordPress
August 8, 2014development wordpress
If you have already defined your custom taxonomy in another plugin and want to use it in a custom post type that you might register in a second plugin, you'll need to add something like this in your custom post type definition. The
register\_taxonomy\_for\_object\_type($taxonomy, $object_type)] function is quite nifty. I've also used it to enable the standard Category taxonomy on Pages.
