Comprehensive Curriculum Breakdown
Module 1: WooCommerce Core Architecture, Lifecycle & Tooling
- Understanding the WooCommerce ecosystem, database schema evolution, and request execution lifecycle.
- Setting up isolated local development stacks using Docker, LocalWP, and WP-CLI.
- Scaffolding custom extensions: Directory architecture, PSR-4 autoloading via Composer, and plugin header metadata.
- Compatibility declarations: Declaring full support for High-Performance Order Storage (HPOS) and cart/checkout block themes.
Module 2: The Hook System (Actions & Filters) & Data CRUD
- Mastering WooCommerce core hooks: Injecting custom logic into catalog loops, single product views, cart lines, and checkout steps.
- Interacting with the WooCommerce CRUD (Create, Read, Update, Delete) Data Store classes:
WC_Product,WC_Order, andWC_Customer. - Custom product meta: Creating custom fields, saving sanitization routines, and displaying data across frontend templates and admin order screens.
- Developing custom Product Types (e.g., rental items, booking slots, dynamic bundle products).
Module 3: Custom Payment Gateway & Shipping Method Development
- Building custom payment gateways from scratch: Extending
WC_Payment_Gatewayand implementing form fields. - Tokenization, secure checkout processing, and defensive webhook capture for asynchronous transaction notifications.
- Engineering dynamic shipping calculation extensions by extending
WC_Shipping_Method. - Integrating external carrier APIs (FedEx, DHL, custom logistics) for real-time rates, dimensional weight calculation, and label triggers.
Module 4: Modern Checkout Blocks, Gutenberg & REST Web APIs
- Transitioning from legacy shortcode checkouts to modern Block-based checkouts.
- Extending WooCommerce Cart and Checkout Blocks using JavaScript, React, and
@woocommerce/blocks-registry. - Extending and securing the WooCommerce REST API: Registering custom endpoints, namespace conventions, and JWT/OAuth access control.
- Handling cart calculations programmatically via the Store API (
/wp-json/wc/store/v1/).
Module 5: Performance, Enterprise Security & Commercialization
- High-Performance Order Storage (HPOS): Querying orders directly from custom database tables instead of legacy
wp_postsandwp_postmeta. - Security hardening: Strict data sanitization, output escaping, nonce validation (
check_admin_referer), and capability checks. - Building custom admin panels using WooCommerce Admin Navigation and React-powered analytics dashboards.
- Packaging, licensing, and auto-update mechanisms for distributing extensions commercially on the WooCommerce Marketplace or private repositories.

Frequently Asked Questions
Do I need prior WordPress plugin development experience before joining? A basic understanding of WordPress concepts (how themes, child themes, and basic plugins work) and foundational Object-Oriented PHP is required. We cover WooCommerce-specific classes, CRUD abstraction layers, and eCommerce hooks systematically from the ground up.
Does this course cover the new High-Performance Order Storage (HPOS)? Yes. HPOS is a critical performance standard in WooCommerce. We teach how to read, write, and index orders using dedicated custom order tables rather than relying on the legacy wp_posts architecture, ensuring your extensions remain fast and compatible with large-scale catalogs.
Can I build extensions for the official WooCommerce.com marketplace with this training?
Yes. The entire curriculum follows the official WooCommerce Marketplace Extension Quality Guidelines—covering internationalization (i18n), clean uninstallation hooks, security checks, and code modularity required to pass automated audits and editorial reviews.
