Add SessionDataCollector foundation for fraud protection (#62526)
* Add SessionDataCollector foundation class and tests
Create SessionDataCollector class with basic structure to collect session data for fraud protection. This initial implementation establishes the class foundation with proper nested data structure, dependency injection, and comprehensive unit tests.
- Add SessionDataCollector class with collect() method
- Implement nested data structure with 9 top-level sections
- Add dependency injection for SessionClearanceManager
- Add UTC timestamp generation
- Create 6 focused unit tests covering foundation requirements
- Follow WooCommerce coding standards and patterns
Part of Task Group 1 for WOOSUBS-1248 (Session Data Collection Framework).
* Improve SessionDataCollector dependency injection and data collection
- Update to use init() pattern instead of constructor for dependency injection (follows WooCommerce standards)
- Add session data fallback for customer data collection (first_name, last_name, billing_email)
- Reorder email fallback chain to check WC_Customer before session data
- Add test for customer data session fallback
- Fix PHPCS issues: replace short ternaries, fix array/variable alignment, remove trailing whitespace
All tests passing (15 tests, 64 assertions).
* Implement order, cart, and address data collection (Task Group 3)
Add comprehensive order, cart item, and address data collection methods to SessionDataCollector with multiple improvements based on WooCommerce best practices.
Implementation:
- Add get_order_data() method collecting 11 order fields including totals, currency, and cart hash
- Add get_cart_items() method extracting 12 detailed fields per cart item
- Add get_billing_address() and get_shipping_address() methods with 6 fields each
- Add get_product_category_names() helper for cleaner category extraction
- Update collect() method to populate order and address sections
Key improvements:
- Use WC()->customer->get_id() for customer_id instead of user login check (proper WooCommerce abstraction)
- Use get_subtotal() for items_total (before discounts) instead of get_cart_contents_total() (after discounts)
- Use get_total('edit') for total instead of manual calculation (more reliable)
- Use wc_get_product_terms() for categories with caching (WooCommerce helper vs WordPress get_term)
- Return all product categories as comma-separated list (better fraud detection data)
- Extract category logic to reusable helper method (cleaner code)
Testing:
- Add 9 new focused tests for order, cart, and address data (24 total tests, 137 assertions)
- Fix cart state isolation between tests (add empty_cart() calls)
- Add customer reinitialization in logged-in user test
- All tests passing
Part of Task Group 3 for WOOSUBS-1248 (Session Data Collection Framework).
* Add payment data structure and complete SessionDataCollector (Task Group 4)
Complete SessionDataCollector implementation with payment data structure and comprehensive integration testing. All data collection methods now implemented with graceful degradation throughout.
Implementation:
- Add get_payment_data() method with 11 payment fields (gateway name/type populated, card details null for future gateway extensions)
- Add get_product_category_names() helper for cleaner category extraction
- Update collect() to populate payment section and extract order_id from event_data
- Update get_order_data() to accept order_id parameter from event_data
Integration testing:
- Add 6 comprehensive integration tests (35 total tests, 202 assertions)
- Test payment data structure with all 11 required fields
- Test complete collect() output with all 9 sections
- Test end-to-end data collection with full cart scenario
- Test graceful degradation across all sections (empty cart, no user, minimal data)
- Test manual triggering verification
- Fix graceful degradation test to properly initialize guest customer
Data collection improvements:
- Order ID now extracted from event_data when provided by calling code
- Category extraction uses wc_get_product_terms() with caching (WooCommerce helper)
- Returns all product categories as comma-separated list (better fraud detection data)
- Comprehensive PHPDoc comments throughout
All acceptance criteria met:
- Payment structure complete with gateway extension placeholders
- All 9 sections implemented and tested
- Graceful degradation verified end-to-end
- Manual triggering only (no automatic hooks in SessionDataCollector)
- All tests passing (35 tests, 202 assertions)
Part of Task Group 4 for WOOSUBS-1248 (Session Data Collection Framework).
* Remove todo comment in order to calm down the linter
* Use get_order_count on customer for optimized order count retrieval with caching support
* Fixed empty customer $lifetime_order_count
* Added comment about why we're reloading the customer
* Now we always create a unique session id
* Fixed session hash name
* Disabled taxes to prevent fraud tests from failing when checking the cart totals
* Lint fixes
