wc-customer-and-sessions

What problem does it solve?

This Skill helps developers correctly use WooCommerce's session and customer abstractions, avoiding $_SESSION and direct cookies that break with page caching, REST, AJAX, cron, and WP-CLI, by guiding data storage and retrieval through WC()->session and WC()->customer.

Core Features & Use Cases

• Correctly read and write per-visitor data with WC()->session, including ephemeral data such as cart state and feature flags.
• Read the active customer's billing/shipping details via WC()->customer, and update them in a way that works for both guests and logged-in users.
• Ensure session initialization in non-frontend contexts (REST, cron, CLI) by calling wc_load_cart() or WC()->initialize_session().

Quick Start

Use WC()->session to store per-visitor data and WC()->customer to read billing info in a plugin context, and call wc_load_cart() in REST or cron contexts when needed.
