Fixed 2 critical issues:
1. API Response Caching - FIXED
Problem: API returns old data without type, status fields
Root Cause: WordPress REST API response caching
Solution:
- Added no-cache headers to response:
* Cache-Control: no-cache, no-store, must-revalidate
* Pragma: no-cache
* Expires: 0
- Added debug logging to verify data structure
- Forces fresh data on every request
Result: API will return fresh data with all fields
2. Variation Attribute Values Missing - FIXED
Problem: Shows "color:" instead of "color: Red"
Root Cause: API returns slugs not human-readable values
Before:
attributes: { "pa_color": "red" }
After:
attributes: { "Color": "Red" }
Solution:
- Remove 'pa_' prefix from attribute names
- Capitalize attribute names
- Convert taxonomy slugs to term names
- Return human-readable format
Code:
- Clean name: pa_color → Color
- Get term: red (slug) → Red (name)
- Format: { Color: Red }
Result: Variations show "color: Red" correctly
Test:
1. Hard refresh browser (Ctrl+Shift+R or Cmd+Shift+R)
2. Check products list - should show type and prices
3. Edit variable product - should show "color: Red"
Fixed 3 critical issues:
1. ✅ Price and Type Column Display
Problem: Columns showing empty even though data exists
Root Cause: price_html returns empty string for products without prices
Solution:
- Added fallback chain in index.tsx:
1. Try price_html (formatted HTML)
2. Fallback to regular_price (plain number)
3. Fallback to "—" (dash)
- Added fallback for type: {product.type || '—'}
Now displays:
- Formatted price if available
- Plain price if no HTML
- Dash if no price at all
2. ✅ Redirect After Create Product
Problem: Stays on form after creating product
Expected: Return to products index
Solution:
- Changed New.tsx redirect from:
navigate(`/products/${response.id}`) → navigate('/products')
- Removed conditional logic
- Always redirect to index after successful create
User flow now:
Create product → Success toast → Back to products list ✅
3. ✅ Edit Form Not Loading Data
Problem: Edit form shows empty fields instead of product data
Root Cause: Missing fields in API response (virtual, downloadable, featured)
Solution:
- Added to format_product_full() in ProductsController.php:
* $data['virtual'] = $product->is_virtual();
* $data['downloadable'] = $product->is_downloadable();
* $data['featured'] = $product->is_featured();
Now edit form receives complete data:
- Basic info (name, type, status, descriptions)
- Pricing (SKU, regular_price, sale_price)
- Inventory (manage_stock, stock_quantity, stock_status)
- Categories & tags
- Virtual, downloadable, featured flags
- Attributes & variations (for variable products)
Result:
✅ Products list shows prices and types correctly
✅ Creating product redirects to index
✅ Editing product loads all data properly
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)
