Advanced Woo
Customizing the checkout flow and product pages.
Key Concepts
- Template Overrides: Safe customization.
- Checkout Fields: Adding custom data.
- Payment Gateways: Integrating custom providers.
1. High-Performance Order Storage (HPOS)
WooCommerce is moving orders to custom tables. Ensure your code is compatible.
2. Template Structure
Copy templates to `theme/woocommerce/` to override them safely. Never edit core files.
3. Hooks & Filters
WooCommerce is event-driven. Use hooks like `woocommerce_before_cart` to inject content.
4. Custom Checkout Fields
Add fields to the checkout and save them to order meta.
5. Product Data Tabs
Add custom tabs to the product page to display NocoDB data or technical specs.
6. AJAX Fragments
Update the mini-cart without reloading the page using WC Fragments.
7. Custom Payment Gateway
Extend `WC_Payment_Gateway` to integrate a niche payment provider.
8. REST API
Use the WC REST API to build mobile apps or integrate with ERP systems.
9. Scalability
Disable the cart for bots. Use Redis for session storage. Offload static assets.
10. Testing
Use E2E testing (Cypress/Playwright) to ensure the checkout flow works after every update.
