Critical Fixes:
1. ✅ PHP Fatal Error - FIXED
Problem: call_user_func() error - Permissions::check_admin does not exist
Cause: Method name mismatch in ProductsController.php
Solution: Changed all 8 occurrences from:
'permission_callback' => [Permissions::class, 'check_admin']
To:
'permission_callback' => [Permissions::class, 'check_admin_permission']
Affected routes:
- GET /products
- GET /products/:id
- POST /products
- PUT /products/:id
- DELETE /products/:id
- GET /products/categories
- GET /products/tags
- GET /products/attributes
2. ✅ Attribute Options Input - FIXED
Problem: Cannot type anything after first word (cursor jumps)
Cause: Controlled input with immediate state update on onChange
Solution: Changed to uncontrolled input with onBlur
Changes:
- value → defaultValue (uncontrolled)
- onChange → onBlur (update on blur)
- Added key prop for proper re-rendering
- Added onKeyDown for Enter key support
- Updated help text: "press Enter or click away"
Now you can:
✅ Type: Red, Blue, Green (naturally!)
✅ Type: Red | Blue | Green (pipe works too!)
✅ Press Enter to save
✅ Click away to save
✅ No cursor jumping!
Result:
- Products index page loads without PHP error
- Attribute options input works naturally
- Both comma and pipe separators supported
Fixed Issues:
1. TypeScript error on .indeterminate property (line 332)
- Cast checkbox element to any for indeterminate access
2. API error handling for categories/tags endpoints
- Added is_wp_error() checks
- Return empty array on error instead of 500
Next: Implement modern tabbed product form (Shopify-style)
