SYSTEM DOCUMENTATION & REQUIREMENTS

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.

FAQPage Schema

Why is WooCommerce session data not working in REST API or cron contexts?▼

WooCommerce session data is unavailable in REST API, cron, and CLI contexts because WC()->session is not auto-initialized; you must call wc_load_cart() or WC()->initialize_session() to enable session reading and writing in these environments. This Skill defines those initialization rules.

How do I get customer billing details for both guest and logged-in users in WooCommerce?▼

To get customer billing details for both guest and logged-in users, read the active customer's billing and shipping data via WC()->customer. This Skill guides proper data retrieval and update rules that work consistently across frontend and non-frontend contexts.

Should I use PHP native sessions for WooCommerce cart and visitor data?▼

You should not use PHP native sessions for WooCommerce cart and visitor data because they break with page caching, REST, AJAX, cron, and WP-CLI. This Skill guides data storage through WC()->session and WC()->customer abstractions instead.

What is the best way to store per-visitor cart state and feature flags in WooCommerce?▼

The best way to store per-visitor cart state and feature flags in WooCommerce is using WC()->session to read and write ephemeral data. This Skill defines usage rules for session storage and auto-initialization to ensure data persistence without breaking page caching.

Does WooCommerce session handling work with admin-ajax and WP-CLI?▼

WooCommerce session handling does work with admin-ajax and WP-CLI, but WC()->session may be unavailable by default. This Skill ensures correct data flow by applying wc_load_cart() and WC()->initialize_session() to properly initialize sessions in these non-frontend contexts.

When do I need to initialize WooCommerce sessions manually?▼

You need to initialize WooCommerce sessions manually in non-frontend contexts such as REST API requests, cron jobs, and WP-CLI commands where WC()->session is unavailable. This Skill defines when to call wc_load_cart() or WC()->initialize_session() to ensure proper data retrieval.
