ProductsStore::register_getters │ private static │ WC 1.0

Register the derived-state getters once.

These closures mirror the JS getters in client/blocks/assets/js/base/stores/woocommerce/products.ts so that directives referencing state.mainProductInContext / state.productVariationInContext / state.productInContext resolve during SSR. Because they read from wp_interactivity_state() at call time, they only need to be registered once regardless of how many products are added.

Method of the class: ProductsStore{}

No Hooks.

Returns

null. Nothing (null).

Usage

$result = ProductsStore::register_getters(): void;
