+# Rajaongkir Integration with WooNooW
+
+This guide explains how to bridge the Rajaongkir shipping plugin with WooNooW's admin order form and checkout flow.
+
+---
+
+## The Challenge
+
+Rajaongkir doesn't use standard WooCommerce address fields. Instead of using `city` and `state`, it requires a **destination ID** from its own Indonesian location database.
+
+**Standard WooCommerce Flow:**
+```
+Country → State → City → Postcode
+```
+
+**Rajaongkir Flow:**
+```
+Country (ID) → Destination ID (subdistrict level)
+```
+
+---
+
+## WooNooW Integration Hook
+
+WooNooW provides a hook that fires **before** shipping calculation. This allows plugins like Rajaongkir to set session variables or prepare any data they need.
+
+### Hook: `woonoow/shipping/before_calculate`
+
+```php
+do_action( 'woonoow/shipping/before_calculate', $shipping_data, $items );
+```
+
+**Parameters:**
+- `$shipping_data` (array) - The shipping address from frontend:
+ - `country` - Country code (e.g., 'ID')
+ - `state` - State code
+ - `city` - City name
+ - `postcode` - Postal code
+ - `address_1` - Street address
+ - `address_2` - Additional address (optional)
+ - + Any custom fields added by addons
+- `$items` (array) - Cart items being shipped
+
+---
+
+## Code Snippet: Rajaongkir Bridge
+
+Add this code to your theme's `functions.php` or via a code snippets plugin:
+
+```php
+session->__unset( 'selected_destination_id' );
+ WC()->session->__unset( 'selected_destination_label' );
+ return;
+ }
+
+ // Check if destination_id is provided by frontend
+ if ( ! empty( $shipping['destination_id'] ) ) {
+ WC()->session->set( 'selected_destination_id', $shipping['destination_id'] );
+ WC()->session->set( 'selected_destination_label', $shipping['destination_label'] ?? $shipping['city'] );
+ return;
+ }
+
+ // Fallback: Try to lookup destination from city name
+ // This requires the Rajaongkir database lookup
+ $destination = rajaongkir_lookup_destination( $shipping['city'], $shipping['state'] );
+ if ( $destination ) {
+ WC()->session->set( 'selected_destination_id', $destination['id'] );
+ WC()->session->set( 'selected_destination_label', $destination['label'] );
+ }
+}, 10, 2 );
+
+/**
+ * Helper: Lookup Rajaongkir destination by city/state name.
+ *
+ * This is a simplified example. Implement based on your Rajaongkir data structure.
+ */
+function rajaongkir_lookup_destination( $city, $state ) {
+ // Query the Rajaongkir location database
+ // This depends on how your Rajaongkir plugin stores location data
+
+ // Example using transient/option storage:
+ $locations = get_option( 'cekongkir_destinations', [] );
+
+ foreach ( $locations as $location ) {
+ if (
+ stripos( $location['city'], $city ) !== false ||
+ stripos( $location['district'], $city ) !== false
+ ) {
+ return [
+ 'id' => $location['id'],
+ 'label' => $location['label'],
+ ];
+ }
+ }
+
+ return null;
+}
+```
+
+---
+
+## Frontend Integration (Optional)
+
+To add a proper Rajaongkir destination selector to WooNooW's admin order form, you need to:
+
+### 1. Register Custom Address Fields
+
+```php
+add_filter( 'woonoow/checkout/address_fields', function( $fields ) {
+ // Only for Indonesia
+ if ( WC()->customer && WC()->customer->get_shipping_country() === 'ID' ) {
+ $fields['destination_id'] = [
+ 'type' => 'hidden',
+ 'required' => true,
+ ];
+ $fields['destination_selector'] = [
+ 'type' => 'custom',
+ 'component' => 'RajaongkirDestinationSelector',
+ 'label' => __( 'Destination', 'woonoow-rajaongkir' ),
+ 'required' => true,
+ ];
+ }
+ return $fields;
+} );
+```
+
+### 2. Enqueue JavaScript for Destination Search
+
+```php
+add_action( 'woonoow/admin/enqueue_scripts', function() {
+ wp_enqueue_script(
+ 'woonoow-rajaongkir',
+ plugins_url( 'assets/js/woonoow-integration.js', __FILE__ ),
+ [ 'woonoow-admin' ],
+ '1.0.0',
+ true
+ );
+
+ wp_localize_script( 'woonoow-rajaongkir', 'WNW_RAJAONGKIR', [
+ 'ajaxUrl' => admin_url( 'admin-ajax.php' ),
+ 'nonce' => wp_create_nonce( 'rajaongkir_search' ),
+ ] );
+} );
+```
+
+---
+
+## Testing
+
+1. Install and configure Rajaongkir plugin
+2. Add the code snippet above
+3. Go to WooNooW → Orders → Create New Order
+4. Add a product
+5. Set country to Indonesia
+6. Fill in city/state (or use destination selector if implemented)
+7. Click "Calculate Shipping"
+8. Verify Rajaongkir rates appear
+
+---
+
+## Troubleshooting
+
+### Rates not appearing?
+
+1. Check browser DevTools Network tab for `/shipping/calculate` response
+2. Look for `debug` object in response:
+ ```json
+ {
+ "methods": [...],
+ "debug": {
+ "packages_count": 1,
+ "cart_items_count": 1,
+ "address": { ... }
+ }
+ }
+ ```
+
+3. Verify Rajaongkir session is set:
+ ```php
+ error_log( 'destination_id: ' . WC()->session->get( 'selected_destination_id' ) );
+ ```
+
+### Session not persisting?
+
+Make sure WooCommerce session is initialized before the hook runs. The hook fires during REST API calls where session may not be initialized by default.
