# PaymentController - Booking Migration Implementation
## Overview
Successfully migrated the `handleSuccess()` function in PaymentController from the legacy Reservation model to the new Booking model, with backward compatibility support.
## Changes Made
### 1. **Import Updates**
Added Booking model import:
```php
use App\Models\Booking;
```
### 2. **handleSuccess() Function Complete Rewrite**
#### Key Improvements:
**A. Multi-Level Booking Lookup Strategy:**
```php
// 1. Try to find booking by payment reference
$booking = Booking::where('payment_reference', $orderId)->first();
// 2. Fallback: Try to find by identifier extracted from OrderID
if (!$booking) {
$identifier = Str::after($orderId, 'ZAPAZIME-');
$booking = Booking::where('identifier', $identifier)->first();
}
// 3. Fallback: Try old Reservation model for backward compatibility
if (!$booking) {
$reservation = Reservation::where('payment_reference', $orderId)->first();
// Handle legacy reservations...
}
```
**B. Booking Update with Complete Payment Details:**
```php
DB::transaction(function () use ($booking, $request) {
$booking->update([
'payment_status' => 'paid',
'status' => 'confirmed',
'payment_method' => 'mypos_card',
'confirmed_at' => now(),
'paid_amount' => $booking->total_amount,
]);
// Create payment transaction record
PaymentTransaction::create([
'booking_id' => $booking->id,
'user_id' => $booking->user_id,
'company_id' => $booking->company_id,
'workspace_id' => $booking->workspace_id,
'type' => 'payment',
'payment_method' => 'mypos_card',
'amount' => $booking->total_amount,
'currency' => $booking->currency ?? 'BGN',
'status' => 'completed',
'transaction_ref' => $request->input('IPC_Trnref'),
'gateway_transaction_id' => $request->input('IPC_Trnref'),
'gateway_response' => 'Payment successful',
'response_data' => json_encode($request->except(['password', 'card_number', 'cvv'])),
'processed_at' => now(),
]);
});
```
**C. Enhanced Logging:**
```php
Log::info('Payment success callback received', [
'order_id' => $orderId,
'request_data' => $request->except(['password', 'card_number', 'cvv'])
]);
Log::info('Payment processed successfully', [
'booking_id' => $booking->id,
'booking_number' => $booking->booking_number,
'amount' => $booking->total_amount,
]);
```
**D. SystemLogger Integration:**
```php
// Log exceptions to SystemLogger for tracking
\App\Services\SystemLogger::logException(
$e,
'payment',
'mypos_callback',
auth()->id(),
[
'order_id' => $request->input('OrderID'),
'request_data' => $request->except(['password', 'card_number', 'cvv'])
]
);
```
**E. Auto-Login Functionality:**
```php
// Auto-login user if not authenticated
if (!auth()->check() && $booking->user) {
auth()->login($booking->user);
Log::info('User auto-logged in after payment success', [
'user_id' => $booking->user->id,
'booking_id' => $booking->id
]);
}
```
**F. Backward Compatibility:**
- Legacy Reservation model support maintained
- View receives both `booking` and `reservation` (alias) for compatibility
- Old notification system still works for legacy reservations
## Features Implemented
### 1. **Booking Model Support**
- Primary lookup by `payment_reference`
- Secondary lookup by `identifier`
- Full booking status updates
- Payment transaction record creation
### 2. **Payment Transaction Creation**
- Automatic PaymentTransaction record creation
- Links to booking, user, company, workspace
- Stores gateway transaction reference
- Records complete payment details
- Captures response data (sanitized)
### 3. **Enhanced Error Handling**
- Detailed error logging with stack traces
- SystemLogger integration for error tracking
- User-friendly error messages
- Support reference number in error messages
### 4. **Security Improvements**
- Sensitive data exclusion (password, card_number, cvv)
- Sanitized logging throughout
- Proper exception handling
- Transaction safety with DB::transaction()
### 5. **Backward Compatibility**
- Legacy Reservation model support
- Old notification system preserved
- View compatibility maintained
- Gradual migration path
## Database Updates
### Booking Table Updates:
```php
'payment_status' => 'paid',
'status' => 'confirmed',
'payment_method' => 'mypos_card',
'confirmed_at' => now(),
'paid_amount' => $booking->total_amount,
```
### PaymentTransaction Creation:
```php
PaymentTransaction::create([
'booking_id' => $booking->id,
'user_id' => $booking->user_id,
'company_id' => $booking->company_id,
'workspace_id' => $booking->workspace_id,
'type' => 'payment',
'payment_method' => 'mypos_card',
'amount' => $booking->total_amount,
'currency' => $booking->currency ?? 'BGN',
'status' => 'completed',
'transaction_ref' => $request->input('IPC_Trnref'),
'gateway_transaction_id' => $request->input('IPC_Trnref'),
'gateway_response' => 'Payment successful',
'response_data' => json_encode($request->except(['password', 'card_number', 'cvv'])),
'processed_at' => now(),
]);
```
## Lookup Strategy
### Priority Order:
1. **Booking by payment_reference** - Direct match with OrderID
2. **Booking by identifier** - Extracted from OrderID (after 'ZAPAZIME-')
3. **Legacy Reservation** - Backward compatibility for old bookings
### Example OrderID Formats:
- `ZAPAZIME-BK20250124ABC123` → identifier: `BK20250124ABC123`
- Direct payment_reference match
## Error Handling
### Error Scenarios Covered:
1. **Missing OrderID** - Throws exception with clear message
2. **Booking Not Found** - Logs error with all lookup attempts
3. **Database Errors** - Transaction rollback, detailed logging
4. **General Exceptions** - SystemLogger integration, user-friendly messages
### Error Logging:
```php
Log::error('Booking not found for payment reference', [
'order_id' => $orderId,
'extracted_identifier' => Str::after($orderId, 'ZAPAZIME-')
]);
```
## View Integration
### View Data Passed:
```php
return view('payments.success', [
'booking' => $booking,
'reservation' => $booking // For backward compatibility
]);
```
This allows the view to work with both new and legacy code.
## Notifications (TODO)
### Placeholder for Future Notifications:
```php
// TODO: Create BookingPaymentNotification and BookingConfirmedNotification
// $booking->user->notify(new BookingPaymentNotification($booking));
// $booking->user->notify(new BookingConfirmedNotification($booking));
```
### Action Items:
1. Create `BookingPaymentNotification` class
2. Create `BookingConfirmedNotification` class
3. Update email templates for booking notifications
4. Test notification delivery

## handleCancel() Function Migration
### Complete Rewrite with Booking Support:
**A. Multi-Level Booking Lookup (Same as handleSuccess):**
```php
// 1. Try to find booking by payment reference
$booking = Booking::where('payment_reference', $orderId)->first();
// 2. Fallback: Try to find by identifier
if (!$booking) {
$identifier = Str::after($orderId, 'ZAPAZIME-');
$booking = Booking::where('identifier', $identifier)->first();
}
// 3. Fallback: Legacy Reservation support
if (!$booking) {
$reservation = Reservation::where('payment_reference', $orderId)->first();
// Handle legacy cancellations...
}
```
**B. Booking Cancellation Update:**
```php
DB::transaction(function () use ($booking, $request) {
$booking->update([
'payment_status' => 'cancelled',
'status' => 'cancelled',
'cancelled_at' => now(),
'cancellation_reason' => 'Payment cancelled by user'
]);
// Create payment transaction record for cancelled payment
PaymentTransaction::create([
'booking_id' => $booking->id,
'user_id' => $booking->user_id,
'company_id' => $booking->company_id,
'workspace_id' => $booking->workspace_id,
'type' => 'payment',
'payment_method' => 'mypos_card',
'amount' => $booking->total_amount,
'currency' => $booking->currency ?? 'BGN',
'status' => 'cancelled',
'transaction_ref' => $request->input('IPC_Trnref'),
'gateway_transaction_id' => $request->input('IPC_Trnref'),
'gateway_response' => 'Payment cancelled by user',
'response_data' => json_encode($request->except(['password', 'card_number', 'cvv'])),
'processed_at' => now(),
]);
});
```
**C. Enhanced Logging:**
```php
Log::info('Payment cancellation callback received', [
'order_id' => $orderId,
'request_data' => $request->except(['password', 'card_number', 'cvv'])
]);
Log::info('Payment cancelled successfully', [
'booking_id' => $booking->id,
'booking_number' => $booking->booking_number,
]);
```
**D. SystemLogger Integration:**
```php
\App\Services\SystemLogger::logException(
$e,
'payment',
'mypos_cancel',
auth()->id(),
[
'order_id' => $request->get('OrderID'),
'request_data' => $request->except(['password', 'card_number', 'cvv'])
]
);
```
**E. Auto-Login Functionality:**
```php
// Auto-login user if not authenticated
if (!auth()->check() && $booking->user) {
auth()->login($booking->user);
Log::info('User auto-logged in after payment cancellation', [
'user_id' => $booking->user->id,
'booking_id' => $booking->id
]);
}
```
### Cancellation Features:
1. **Complete Cancellation Tracking:**
- Updates booking status to 'cancelled'
- Records cancellation timestamp
- Stores cancellation reason
- Creates PaymentTransaction with 'cancelled' status
2. **Transaction History:**
