Problem: Routes were registered but methods didn't exist, causing 500 Internal Server Error
Error: 'The handler for the route is invalid'
Root Cause: The previous multi_edit tool call failed to add the method implementations.
Only the route registrations were added, but the actual PHP methods were missing.
Solution: Added all 9 taxonomy CRUD methods to ProductsController:
Categories:
- create_category() - Uses wp_insert_term()
- update_category() - Uses wp_update_term()
- delete_category() - Uses wp_delete_term()
Tags:
- create_tag() - Uses wp_insert_term()
- update_tag() - Uses wp_update_term()
- delete_tag() - Uses wp_delete_term()
Attributes:
- create_attribute() - Uses wc_create_attribute()
- update_attribute() - Uses wc_update_attribute()
- delete_attribute() - Uses wc_delete_attribute()
Each method includes:
✅ Input sanitization
✅ Error handling with WP_Error checks
✅ Proper response format matching frontend expectations
✅ Try-catch blocks for exception handling
Files Modified:
- includes/Api/ProductsController.php (added 354 lines of CRUD methods)
Result:
✅ All taxonomy CRUD operations now work
✅ No more 500 Internal Server Error
✅ Categories, tags, and attributes can be created/updated/deleted
