WebRainbow - Delivery Date

WooCommerce delivery-date rules for classic checkout and Checkout Blocks.

Requirements

• WordPress with the site timezone configured correctly
• WooCommerce 8.9 or newer
• PHP 7.4 or newer

Delivery rules

The server is the source of truth. A submitted date must satisfy every applicable rule:

1. Minimum lead time and the optional priority-category cutoff.
2. Global booking horizon and every product's “deliver no later than” date.
3. Default weekdays, matching category restrictions, and product restrictions.
4. Excluded dates and the optional December 27–January 2 closure.
5. The configured city list for the restricted weekday.

Weekday restrictions are intersected. If one cart item allows only Tuesday and another allows only Friday, the cart has no valid delivery weekday and checkout displays a warning.

The priority-category rule includes descendant product categories. Local-pickup orders and carts that do not need shipping do not require a delivery date.

Upgrade notes from 2.x

• Existing webrainbow_delivery_date_settings options and product metadata remain supported.
• Existing classic orders continue using _delivery_date.
• Checkout Blocks store their value through WooCommerce's Additional Checkout Fields API.
• The old hardcoded timezone was removed; calculations now use the WordPress site timezone.
• The Wednesday city restriction is now enforced on the server. Review the configured city spellings after updating.
• Rules previously shown in the admin UI but ignored by checkout are now active.
