fix(rajaongkir): correct API method name and remove premature country check
Root causes fixed: 1. API method: search_destination_api() not search_destination() 2. Field filter: removed country check that failed before user selection 3. Field now always added if store sells to Indonesia The woocommerce_checkout_fields filter now: - Checks if Rajaongkir is active - Checks if Indonesia is in allowed countries - Always adds field (frontend will show/hide based on country)

## Troubleshooting
|
||||
|
||||
### Destination field not appearing?
|
||||
### API returns empty?
|
||||
|
||||
Check if:
|
||||
- Country is set to Indonesia
|
||||
- Rajaongkir plugin is active
|
||||
- Snippet has no syntax errors
|
||||
|
||||
Debug in PHP:
|
||||
Check `debug.log` for errors:
|
||||
```php
|
||||
add_action('woocommerce_checkout_init', function() {
|
||||
$fields = WC()->checkout()->get_checkout_fields();
|
||||
error_log('Shipping fields: ' . print_r(array_keys($fields['shipping'] ?? []), true));
|
||||
});
|
||||
// Added logging in the search function
|
||||
error_log('Rajaongkir search error: ...');
|
||||
```
|
||||
|
||||
### Search returns empty?
|
||||
Common issues:
|
||||
- Invalid Rajaongkir API key
|
||||
- Rajaongkir plugin not active
|
||||
- API quota exceeded
|
||||
|
||||
```php
|
||||
// Add to the search endpoint
|
||||
error_log('Rajaongkir search: ' . $search);
|
||||
error_log('Results: ' . print_r($results, true));
|
||||
```
|
||||
### Field not appearing?
|
||||
|
||||
### Rajaongkir rates not appearing?
|
||||
1. Ensure snippet is active
|
||||
2. Check if store sells to Indonesia
|
||||
3. Check browser console for JS errors
|
||||
|
||||
### Rajaongkir rates not showing?
|
||||
|
||||
1. Check session is set:
|
||||
```php
|
||||
add_action('woonoow/shipping/before_calculate', function($shipping) {
|
||||
error_log('Destination ID in shipping data: ' . print_r($shipping, true));
|
||||
error_log('Session destination: ' . WC()->session->get('selected_destination_id'));
|
||||
error_log('Shipping data: ' . print_r($shipping, true));
|
||||
}, 5);
|
||||
```
|
||||
|
||||
2. Check Rajaongkir debug:
|
||||
- Enable debug in Rajaongkir settings
|
||||
- Check `debug.log` for Rajaongkir messages
|
||||
2. Check Rajaongkir is enabled in shipping zone
|
||||

||||

|
||||
|
||||
## Known Limitations
|
||||
|
||||
1. **Field visibility**: Currently field always shows for checkout. Future improvement: hide in React when country ≠ ID.
|
||||
|
||||
2. **Session timing**: Must select destination before calculating shipping.
