ROOT CAUSE FOUND!
OrdersController registered /products BEFORE ProductsController:
- OrdersController::init() called first (line 25 in Routes.php)
- ProductsController::register_routes() called later (line 95)
- WordPress uses FIRST matching route
- OrdersController /products was winning!
This explains EVERYTHING:
✅ Route registered: SUCCESS
✅ Callback is_callable: YES
✅ Permissions: ALLOWED
✅ Request goes to /woonoow/v1/products
❌ But OrdersController::products() was handling it!
Solution:
1. Changed OrdersController route from /products to /products/search
2. Updated ProductsApi.search() to use /products/search
3. Now /products is free for ProductsController!
Result:
- /products → ProductsController::get_products() (full product list)
- /products/search → OrdersController::products() (lightweight search for orders)
This will finally make ProductsController work!
