How to restrict coupons to WooCommerce custom taxonomies

Smart Coupons provide a powerful, “all-in-one” solution for gift cards, store credits, discount coupons, and vouchers extending the core functionality of WooCommerce coupons.

If you want to exclude all your popular subscription products from coupon discounts, or include discounts on all products sharing the common tag and other product-related use cases, the coupon taxonomy restriction feature can help you achieve it.

In this document, you can find ways to restrict coupons to the custom taxonomies that you have created.

To create a custom taxonomy such as Material, Warranty, Occasion, or Style, you can find plugins that are available on the wordpress.org/plugins page that is available by searching with “woocommerce custom taxonomy”.

A free plugin that can be used to create custom taxonomies is https://wordpress.org/plugins/custom-post-type-ui/

If you are familiar with custom codes, you can utilize the code available below:

// Register 'Collection' Custom Taxonomy for WooCommerce Products
function register_product_collection_taxonomy() {
    $labels = array(
        'name'              => _x( 'Collections', 'taxonomy general name', 'textdomain' ),
        'singular_name'     => _x( 'Collection', 'taxonomy singular name', 'textdomain' ),
        'search_items'      => __( 'Search Collections', 'textdomain' ),
        'all_items'         => __( 'All Collections', 'textdomain' ),
        'parent_item'       => __( 'Parent Collection', 'textdomain' ),
        'parent_item_colon' => __( 'Parent Collection:', 'textdomain' ),
        'edit_item'         => __( 'Edit Collection', 'textdomain' ),
        'update_item'       => __( 'Update Collection', 'textdomain' ),
        'add_new_item'      => __( 'Add New Collection', 'textdomain' ),
        'new_item_name'     => __( 'New Collection Name', 'textdomain' ),
        'menu_name'         => __( 'Collections', 'textdomain' ),
    );

    $args = array(
        'hierarchical'      => true, // Like categories
        'labels'            => $labels,
        'show_ui'           => true,
        'show_admin_column' => true,
        'rewrite'           => array( 'slug' => 'collection' ),
        'show_in_rest'      => true, // To make it visible in Gutenberg and REST API
    );

    register_taxonomy( 'product_collection', array( 'product' ), $args );
}
add_action( 'init', 'register_product_collection_taxonomy' );
