Elállás for WooCommerce — integration & extension

For developers making a plugin/theme work with Elállás for WooCommerce (elallas-for-woo, by uptools.io) — the online right-of-withdrawal (elállási jog) button + case-management plugin for WooCommerce, built for EU Directive 2023/2673 and 415/2025. (XII. 23.) Korm. rendelet. It manages a withdrawal "case" per order in its own tables and fires a small, clean set of elallas_* hooks for integrators.

This is an LW-family plugin — consume hooks, don't edit it

Namespace LightweightPlugins\Elallas, tables wp_lw_elallas_*, and it integrates with LW Site Manager — it's part of the LightweightPlugins family. Integrate by consuming its elallas_* hooks and reading its data; never patch the plugin. If you need an extension point that doesn't exist, request it upstream rather than editing.

Detect it:

if ( defined( 'ELALLAS_FOR_WOO_VERSION' ) ) { /* Elállás for WooCommerce active (1.0.12 tested) */ }

It requires WooCommerce 8.0+ and is HPOS-safe — every hook hands you a real \WC_Order, so use $order->get_*() (never post meta) — see wc-hpos-compatibility.

Extension point 1 — eligibility, deadline, B2B & order numbers

The first four filters decide whether an order may start a withdrawal and how the deadline is computed; they receive the \WC_Order. elallas_resolve_order_number runs earlier, before the order exists, and maps the customer-entered display order number to a WooCommerce order ID.
