I have studies the database intensively and know which all tables are updated when a category is added to a product. Is there any inbuilt woocommerce function to add categories? It updates 2 or 3 tables but want to leave it to woocommerce.

Thanks for your help.

  • have you tried with wp_set_object_terms ?

  • Could you clarify what you are trying to do? Woo's "product categories" are really just a custom taxonomy ( product_cat ) and adrian's suggestion would work fine. Jul 28, 2013 at 13:08

I think the function you are looking for is called wp_insert_term() in WordPress core. Woocommerce uses WordPress-taxonomy called product_cat

So if you want to add some categories for example phones:

function wpse_insert_term()
      'product_cat', // the taxonomy
        'description'=> 'A yummy phone.',
        'slug' => 'phone',
add_action('init', 'wpse_insert_term');
