I have a Custom Post Type that uses the default category, the same as the posts, and some other post types in my site. How can I list all non-empty categories from the custom post type?
For instance, if I have categories “Cat 1”, “Cat 2" and “Cat 3” and I have a default post with a category of “Cat 1", and a custom post with categories “Cat 2” and “Cat 3". How would I write a function that would return “Cat 2” and “Cat 3"?
It seems like the
get_terms() functions don’t support a
post_type argument. Is there a way I can add some other query to a
I know that it is possible to hide unused terms:
$terms = get_terms( array( 'taxonomy' => 'category', 'hide_empty' => true, <----- ) );
However this hides empty for all post types, I'd like to hide empty for just a custom post type.
