Booking Submission Implementation Status

Overview

Implementation of two-phase booking submission for the booking creation flow. This allows users to create new bookings through inquiry validation followed by final booking commit.

Status: ✅ 100% Complete - TESTED SUCCESSFULLY Last Updated: 2025-10-06 First Successful Test Booking: 2025-10-06 Related Documentation:

• docs/BOOKING_PAYMENT_STEP.md - Payment step implementation
• docs/REFACTORING_BOOKING_DATA_PROCESSOR.md - Future refactoring plan

Architecture Decision

Participant-Centric Structure: The CREATE flow uses a cleaner participant-centric data structure where services are attached directly to participants in the DTO, not centralized with mapping arrays. This is the new standard.

UPDATE Flow: Currently uses a different structure (centralized services with mappings). Future refactoring will align it with the CREATE flow's participant-centric approach.

Completed Work (80%)

1. Response Models ✅

Created Files:

• src/BusProNet/Model/BookingResponse.php
• src/BusProNet/Model/PriceItem.php
• src/BusProNet/Model/PaymentTerms.php

BookingResponse:

• Represents API response from booking requests (inquiry or final)
• Properties: status, transactionNumber, priceItems, totalPrice, paymentTerms
• Methods: isInquiryValid(), isBookingSuccessful()
• Handles both möglich (inquiry valid) and erfolgt (booking created) statuses

PriceItem:

• Represents individual price items from response
• Properties: position, type, subType, label, dateFrom, dateTo, quantity, assignment, unitPrice, totalPrice, id
• Used for price validation against calculated prices

PaymentTerms:

• Represents payment schedule from response
• Properties: depositAmount, depositDate, finalPaymentAmount, finalPaymentDate

2. Response Parser ✅

File: src/BusProNet/XmlParser/BookingResponseParser.php

Functionality:

• Extends AbstractParser
• Parses BUCHUNG type responses
• Extracts booking status from <buchung> node
• Extracts transaction number from <vorgang> node
• Parses all price items from <preise><preis> nodes
• Parses total price from <gesamtpreis> node
• Parses payment terms from <zahlungsbedingungen> node

XML Structure Handled:

<ergebnis>
    <satz typ="BUCHUNG" />
    <buchung>möglich|erfolgt</buchung>
    <vorgang>321530</vorgang>
    <preise>
        <preis position="1" art="BEF" unterart="BUS" bezeichnung="..."
               terminvon="..." terminbis="..." anzahl="2" zuordnung="1,2"
               preis="50.00" gesamtpreis="100.00" id="123" />
    </preise>
    <gesamtpreis>671,78</gesamtpreis>
    <zahlungsbedingungen>
        <anzahlung betrag="128,00" termin="21.03.2017" />
        <restzahlung betrag="543,78" termin="12.11.2017" />
    </zahlungsbedingungen>
</ergebnis>

3. Constants ✅

File: src/BusProNet/Constants.php

Added:

• PAYMENT_TYPE_ID_TRANSFER = 2 - Payment type ID for bank transfer
• PAYMENT_TYPE_ID_DEBIT = 5 - Payment type ID for direct debit

4. Payload Generation ✅

File: src/BusProNet/DataProcessor/BookingDataProcessor.php

New Method: createBookingRequestPayload(BookingCreateDto $bookingDto, string $bookingType): array

Functionality:

• Generates XML payload for new bookings (inquiry or final)
• Supports both 'Anfrage' (inquiry) and 'Buchung' (final booking) modes
• Participant-centric structure (services attached to participants)
• Includes ALL service types: board, ski passes, rentals, courses, additional services, transportation, pickups
• INCLUDES INSURANCE (critical difference from update flow)
• Proper room mapping via assignedRoomId
• Payment information with correct type IDs

Helper Methods:

• addServicesFromMap() - Reusable helper for converting service maps to XML structure
• collectServiceMappings() - Groups all participant services by ID
• collectTransportationMappings() - Groups transportation services
• collectRoomMappings() - Groups room assignments
• collectPickupMappings() - Groups pickup selections
• collectInsuranceMappings() - Groups insurance selections (CREATE only!)

Payload Structure:

[
    'buchungsart' => 'Anfrage|Buchung',
    'status' => 'F',
    'idreise' => $travelId,
    'anmelder' => [
        'name' => '...',
        'vorname' => '...',
        'geschlecht' => '...',
        'nationalitaet' => '...',
        'geburtsdatum' => '...',
        'kommunikation' => ['email' => '...', 'telefonmobil' => '...'],
    ],
    'teilnehmerliste' => ['teilnehmer' => [...]],
    'beförderungen' => ['beförderung' => [...]],
    'unterbringungen' => ['unterbringung' => [...]],
    'zusatzleistungen' => ['zusatzleistung' => [...]],
    'zustiege' => ['zustieg' => [...]],
    'versicherungen' => ['versicherung' => [...]],  // CREATE only!
    'zahlung' => [
        '@idzahlungsart' => 2|5,
        '@art' => 'EINZUG|UEBERWEISUNG',
        'bankverbindung' => [...],  // if debit
    ],
]

5. API Client Methods ✅

File: src/BusProNet/ApiClient.php

New Constant:

• TYPE_BOOKING = 'BUCHUNG'

New Methods:

public function createBookingInquiry(
    BookingCreateDto $bookingDto,
    bool $debug = false
): Notification|BookingResponse

• First phase: validates booking data
• Returns pricing information
• Does not create actual booking

public function createBooking(
    BookingCreateDto $bookingDto,
    bool $debug = false
): Notification|BookingResponse

• Second phase: creates actual booking
• Returns booking number (transaction number)
• Only called after successful inquiry

Both methods:

• Use BookingDataProcessor::createBookingRequestPayload()
• Send request to BUCHUNG type endpoint
• Return Notification on error or BookingResponse on success
• Support debug mode for XML dumps

6. Response Parser Integration ✅

File: src/BusProNet/XmlParser/ApiResponseParser.php

Updated:

• Added case for ApiClient::TYPE_BOOKING
• Routes to BookingResponseParser
• Handles both inquiry and final booking responses

Remaining Work (0%)

        if ($inquiryResponse instanceof Notification) {
            // API returned error notification
            $this->addFlash('error', $inquiryResponse->message);
            return $this->render(...);
        }

        if (false === $inquiryResponse->isInquiryValid()) {

            $this->addFlash('error', 'Buchungsvalidierung fehlgeschlagen.');
            return $this->render(...);
        }

        // Optional: Validate prices match our calculations
        // Compare $inquiryResponse->totalPrice with calculated total

        // Phase 2: Booking (Commit)
        $bookingResponse = $this->apiClient->createBooking($bookingCreateDto);

        if ($bookingResponse instanceof Notification) {
            // API returned error notification
            $this->addFlash('error', $bookingResponse->message);
            return $this->render(...);
        }

        if (false === $bookingResponse->isBookingSuccessful()) {

            $this->addFlash('error', 'Buchung konnte nicht erstellt werden.');
            return $this->render(...);
        }

        // Success: Clear session and redirect
        $this->bookingService->clearBookingCreateDto($request);

            'bookingNumber' => $bookingResponse->transactionNumber,
        ]);

    } catch (\Exception $e) {
        $this->logger->error('Booking creation failed', [
            'exception' => $e->getMessage(),
            'trace' => $e->getTraceAsString(),
        ]);

        $this->addFlash('error', 'Ein technischer Fehler ist aufgetreten.');
        return $this->render(...);
    }
}

public function __construct(
    private readonly BookingService $bookingService,
    private readonly ApiClient $apiClient,
    private readonly LoggerInterface $logger,
) {
}

2. Service Layer ✅

File: src/Service/BookingService.php

Completed:

4. Testing ⏳

Sandbox Testing Checklist:

• Test inquiry phase with valid data
• Test inquiry phase with invalid data (validation errors)
• Test booking phase after successful inquiry
• Test booking phase failure scenarios
• Verify pricing data matches calculations
• Test with different service combinations:
  • With insurance
  • Without insurance
  • With transportation services
  • With pickup locations
  • With all service types
  • Minimum services only
• Test payment methods:
  • Direct debit (14+ days before travel)
  • Bank transfer
  • Direct debit blocked (<14 days)
• Test session clearing
• Verify booking number display
• Test error handling
• Verify XML dumps in debug mode

Key Implementation Notes

Two-Phase Process

1. Phase 1: Inquiry (buchungsart => 'Anfrage')

   • Validates all booking data
   • Returns pricing information
   • Response: <buchung>möglich</buchung>
   • No actual booking created

2. Phase 2: Booking (buchungsart => 'Buchung')

   • Creates actual booking
   • Returns booking number
   • Response: <buchung>erfolgt</buchung>
   • Only proceed if Phase 1 succeeded

Error Handling

API Errors:

• API may return Notification object instead of BookingResponse
• Check instanceof before accessing BookingResponse methods
• Display error message from notification

Validation Errors:

• Check isInquiryValid() on inquiry response
• Check isBookingSuccessful() on booking response
• Display appropriate error messages

Network/System Errors:

• Catch all exceptions
• Log with full trace
• Display generic error message to user
• Do NOT clear session on error (allow retry)

Price Validation (Optional)

Inquiry response includes:

• Individual price items with quantities and assignments
• Total price from API
• Payment terms (deposit/final payment)

Can compare:

• API total vs calculated total
• Individual service prices
• Participant assignments

Implementation:

if (abs($inquiryResponse->totalPrice - $calculatedTotal) > 0.01) {
    $this->logger->warning('Price mismatch', [
        'api_price' => $inquiryResponse->totalPrice,
        'calculated_price' => $calculatedTotal,
    ]);
    // Decide: continue or abort
}

Session Management

Important:

• Only clear session on successful booking
• Keep session on errors (allows retry)
• Clear using BookingService::clearBookingCreateDto()

Logging

Log events:

• Inquiry submission (info level)
• Inquiry success/failure (info/error)
• Booking submission (info level)
• Booking success/failure (info/error)
• Price mismatches (warning)
• Exceptions (error with full trace)

Context to include:

• Travel ID
• Participant count
• Total price
• Payment method
• Error messages
• Exception traces

Testing Strategy

Unit Tests (Future)

BookingResponseParser:

• Test parsing successful inquiry response
• Test parsing successful booking response
• Test parsing price items
• Test parsing payment terms
• Test handling missing optional fields

BookingDataProcessor:

• Test payload generation with all services
• Test payload generation with minimum services
• Test insurance inclusion
• Test payment methods
• Test participant mappings

Integration Tests (Future)

• Mock socket communication
• Test inquiry request format
• Test booking request format
• Test response parsing
• Test error handling

Controller:

• Test two-phase submission flow
• Test error scenarios
• Test session clearing
• Test redirects

Manual Testing (Immediate)
