How to get all taxonomies which can be added in menu?

Question

I am trying to get list of available taxonomies which WordPress admin users can use in menu section, like Categories, Tags, Product Categories, Product Tags or any custom taxonomy for custom post type. Using get_taxonomies results all taxonomies, some of which are not available in Menu screen, for example Product shipping Class (from woocommerce).

In short, I am trying to get all those taxonomies which are used with Post, Page, Products or any other Custom Post Type in right side of editing screen.

Answer 1

The taxonomies visible in the admin menu are exactly those taxonomies that were registered with show_in_menu = true and show_ui = true. For a reference on this, see the documentation on register_taxonomy, the function for adding (custom) taxonomies.

To query these taxonomies, use the corresponding parameters in get_taxonomies:

get_taxonomies( array(
    'show_ui' => true,
    'show_in_menu' => true,
) );
