A solid reference for WordPress and WooCommerce development that covers the hooks, filters, and security patterns you actually need. It walks through practical examples like custom checkout fields, product type extensions, and REST API routes, all following WordPress coding standards. The security section is worth the price of admission alone with proper nonce verification and sanitization patterns. Good structure for plugin development too, showing namespaced classes and the right directory layout. If you're building custom WooCommerce functionality and want to avoid the common mistakes around data validation and hook priority, this gives you working code patterns instead of forcing you to dig through Stack Overflow threads.
