$post_type (string) - Where to attach this taxonomy to.

$args (array - optional) - Available arguments are:

• label (string) - Custom display name in admin panel. Default is $name capitalized.

Example

BASIC

Registering brand taxonomy to product post type:

H::register_taxonomy( 'brand', 'product' );

CHANGE LABEL & SLUG

H::register_taxonomy('brand', 'product', [
  'label' => 'The Brand',
  'slug' => 'b'
] );

With the snippet above, the admin label will say "The Brand" and the URL for taxonomy page will be /b/brand-name instead of /brand/brand-name.
