# Transportation Services Implementation Plan
|
||||
|
||||
## Overview
|
||||
|
||||
Implement comprehensive transportation services for the MyEP Next Booking system, supporting bus and self-organized (car/PKW) transportation with directional pickup selection, discount handling, and optional parking services. This implementation addresses BusProNet's inconsistent direction naming conventions while following established architectural patterns.
|
||||
|
||||
## Current State Analysis
|
||||
|
||||
### Existing Infrastructure ✅
|
||||
|
||||
**Transportation Data Model:**
|
||||
- `Service` model has `direction`, `subType`, `price` properties
|
||||
- `Travel` model has `transportationServices[]`, `pickupsTo[]`, `pickupsFro[]`
|
||||
- `Booking` model supports transportation service mapping
|
||||
- XML parsing handles transportation services and pickups
|
||||
- Data processing includes transportation service management
|
||||
|
||||
**Form System Integration:**
|
||||
- `ParticipantDto` has transportation and pickup properties
|
||||
- Field handler registry supports service processing
|
||||
- Conditional field state system available
|
||||
- HTMX integration for real-time updates
|
||||
- Pricing integration system in place
|
||||
|
||||
### Direction Naming Inconsistencies 🔍
|
||||
|
||||
**Problem Identified:** BusProNet uses inconsistent direction codes across different contexts:
|
||||
|
||||
1. **Travel Data Context:** `'HIN'` and `'RUECK'` (full German words)
|
||||
2. **Booking Data Context:** `'H'` and `'R'` (single letter abbreviations)
|
||||
3. **Internal Properties:** `To`/`Fro` (archaic English)
|
||||
|
||||
**Evidence:**
|
||||
- Comment in `BookingEditDto.php`: `"Different keys for direction used in booking data (H <=> HIN, R <=> RUECK)!"`
|
||||
- `Travel->getTransportationServicesByDirection('HIN'/'RUECK')`
|
||||
- `Booking->getTransportationServiceForParticipantAndDirection($index, 'H'/'R')`
|
||||
|
||||
### Missing Components 🚧
|
||||
|
||||
- Direction mapping utility for consistency
|
||||
- Transportation field handlers and options providers
|
||||
- Conditional pickup field logic (only show when bus selected)
|
||||
- Parking service integration (subtype PAR)
|
||||
- Modern English property naming (Outbound/Inbound)
|
||||
|
||||
## Implementation Strategy
|
||||
|
||||
### Phase 1: Foundation - Direction Mapping & Naming 🎯
|
||||
|
||||
#### 1.1 Create Direction Mapping Utility
|
||||
|
||||
**File:** `src/BusProNet/Utility/DirectionMapper.php`
|
||||
|
||||
```php
|
||||
<?php
|
||||
|
||||
declare(strict_types=1);
|
||||
|
||||
namespace App\BusProNet\Utility;
|
||||
|
||||
/**
|
||||
* Handles direction mapping between BusProNet's inconsistent direction codes.
|
||||
*
|
||||
* BusProNet uses different direction codes in different contexts:
|
||||
* - Travel data: 'HIN' (outbound), 'RUECK' (inbound)
|
||||
* - Booking data: 'H' (outbound), 'R' (inbound)
|
||||
*
|
||||
* This utility provides consistent mapping between formats.
|
||||
*/
|
||||
final class DirectionMapper
|
||||
{
|
||||
// Travel data format (full German words)
|
||||
public const OUTBOUND_TRAVEL = 'HIN';
|
||||
public const INBOUND_TRAVEL = 'RUECK';
|
||||
|
||||
// Booking data format (single letter abbreviations)
|
||||
public const OUTBOUND_BOOKING = 'H';
|
||||
public const INBOUND_BOOKING = 'R';
|
||||
|
||||
// English naming for internal use
|
||||
public const OUTBOUND = 'outbound';
|
||||
public const INBOUND = 'inbound';
|
||||
|
||||
/**
|
||||
* Maps travel direction code to booking direction code.
|
||||
*/
|
||||
public static function travelToBooking(string $travelDirection): string
|
||||
{
|
||||
return match($travelDirection) {
|
||||
self::OUTBOUND_TRAVEL => self::OUTBOUND_BOOKING,
|
||||
self::INBOUND_TRAVEL => self::INBOUND_BOOKING,
|
||||
default => throw new \InvalidArgumentException("Unknown travel direction: $travelDirection")
|
||||
};
|
||||
}
|
||||
|
||||
/**
|
||||
* Maps booking direction code to travel direction code.
|
||||
*/
|
||||
public static function bookingToTravel(string $bookingDirection): string
|
||||
{
|
||||
return match($bookingDirection) {
|
||||
self::OUTBOUND_BOOKING => self::OUTBOUND_TRAVEL,
|
||||
self::INBOUND_BOOKING => self::INBOUND_TRAVEL,
|
||||
default => throw new \InvalidArgumentException("Unknown booking direction: $bookingDirection")
|
||||
};
|
||||
}
|
||||
|
||||
/**
|
||||
* Maps direction code to English name.
|
||||
*/
|
||||
public static function toEnglish(string $direction): string
|
||||
{
|
||||
return match($direction) {
|
||||
self::OUTBOUND_TRAVEL, self::OUTBOUND_BOOKING => self::OUTBOUND,
|
||||
self::INBOUND_TRAVEL, self::INBOUND_BOOKING => self::INBOUND,
|
||||
default => throw new \InvalidArgumentException("Unknown direction: $direction")
|
||||
};
|
||||
}
|
||||
|
||||
/**
|
||||
* Gets all outbound direction codes.
|
||||
*/
|
||||
public static function getOutboundCodes(): array
|
||||
{
|
||||
return [self::OUTBOUND_TRAVEL, self::OUTBOUND_BOOKING];
|
||||
}
|
||||
|
||||
/**
|
||||
* Gets all inbound direction codes.
|
||||
*/
|
||||
public static function getInboundCodes(): array
|
||||
{
|
||||
return [self::INBOUND_TRAVEL, self::INBOUND_BOOKING];
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
#### 1.2 Update ParticipantDto Properties
|
||||
|
||||
**Current Properties (archaic naming):**
|
||||
```php
|
||||
public ?Service $transportationServiceTo = null;
|
||||
public ?Service $transportationServiceFro = null;
|
||||
public ?Pickup $pickup = null;
|
||||
```
|
||||
|
||||
**Updated Properties (modern English):**
|
||||
```php
|
||||
public ?Service $transportationOutbound = null; // Maps to 'HIN'/'H'
|
||||
public ?Service $transportationInbound = null; // Maps to 'RUECK'/'R'
|
||||
public ?Pickup $pickupOutbound = null; // Maps to pickupsTo
|
||||
public ?Pickup $pickupInbound = null; // Maps to pickupsFro
|
||||
public ?Service $parking = null; // New parking service
|
||||
```
|
||||
|
||||
#### 1.3 Update BookingEditDto Direction Mapping
|
||||
|
||||
**Current Implementation:**
|
||||
```php
|
||||
// Different keys for direction used in booking data (H <=> HIN, R <=> RUECK)!
|
||||
$participantData->transportationServiceTo = $booking
|
||||
->getTransportationServiceForParticipantAndDirection($index, 'H');
|
||||
$participantData->transportationServiceFro = $booking
|
||||
->getTransportationServiceForParticipantAndDirection($index, 'R');
|
||||
```
|
||||
|
||||
**Updated Implementation:**
|
||||
```php
|
||||
use App\BusProNet\Utility\DirectionMapper;
|
||||
|
||||
$participantData->transportationOutbound = $booking
|
||||
->getTransportationServiceForParticipantAndDirection($index, DirectionMapper::OUTBOUND_BOOKING);
|
||||
$participantData->transportationInbound = $booking
|
||||
->getTransportationServiceForParticipantAndDirection($index, DirectionMapper::INBOUND_BOOKING);
|
||||
```
|
||||
|
||||
### Phase 2: Transportation Field Implementation 🚀
|
||||
|
||||
#### 2.1 Transportation Service Field Handlers
|
||||
|
||||
**A. Outbound Transportation Handler**
|
||||
**File:** `src/Form/Service/ParticipantTransportationOutboundFieldHandler.php`
|
||||
|
||||
```php
|
||||
<?php
|
||||
|
||||
declare(strict_types=1);
|
||||
|
||||
namespace App\Form\Service;
|
||||
|
||||
use App\BusProNet\Utility\DirectionMapper;
|
||||
use App\Form\Model\BookingDtoInterface;
|
||||
use App\Form\Service\Abstract\AbstractParticipantFieldHandler;
|
||||
|
||||
/**
|
||||
* Handles processing of outbound transportation service selection.
|
||||
*
|
||||
* Manages outbound (HIN) transportation options including bus and
|
||||
* self-organized (PKW) services with pricing and availability validation.
|
||||
*/
|
||||
class ParticipantTransportationOutboundFieldHandler extends AbstractParticipantFieldHandler
|
||||
{
|
||||
public function getFieldName(): string
|
||||
{
|
||||
return 'transportationOutbound';
|
||||
}
|
||||
|
||||
public function getDependencies(): array
|
||||
{
|
||||
return ['dateOfBirth']; // For age-based discounts
|
||||
}
|
||||
|
||||
public function shouldProcess(array $submittedData, int $participantIndex): bool

||||
$participant = $this->getParticipant($bookingDto, $participantIndex);
|
||||
if (null === $participant) {
|
||||
return;
|
||||
}
|
||||
|
||||
$selectedTransportation = $this->getFieldValue($submittedData, $this->getFieldName());
|
||||
|
||||
// Get available outbound transportation services
|
||||
$availableServices = $bookingDto->travel->getTransportationServicesByDirection(
|
||||
DirectionMapper::OUTBOUND_TRAVEL,
|
||||

|
||||
);
|

// Validate and convert selection to Service object
|

if ($this->isServiceValidForParticipant($selectedTransportation, $availableServices, $bookingDto, $participantIndex)) {
|
||||
$validSelection = $this->findServiceInAvailableServices($selectedTransportation, $availableServices);
|
||||
}
|
||||
}
|
||||
|
||||
// Update participant with validated selection
|
||||
$participant->transportationOutbound = $validSelection;
|
||||
}
|
||||
|
||||
// ... validation methods similar to existing handlers
|
||||
}
|
||||
```
|
||||
|
||||
**B. Inbound Transportation Handler**
|
||||
**File:** `src/Form/Service/ParticipantTransportationInboundFieldHandler.php`
|
||||
- Similar structure for inbound (RUECK) transportation
|
||||
- Field name: `transportationInbound`
|
||||
- Uses `DirectionMapper::INBOUND_TRAVEL`
|
||||
|
||||
#### 2.2 Pickup Field Handlers
|
||||
|
||||
**A. Outbound Pickup Handler**
|
||||
**File:** `src/Form/Service/ParticipantPickupOutboundFieldHandler.php`
|
||||
|
||||
```php
|
||||
<?php
|
||||
|
||||
declare(strict_types=1);
|
||||

|
||||
*
|
||||
* Pickup selection is only processed when outbound transportation
|
||||
* is bus type. Automatically clears pickup when transportation
|
||||
* changes to self-organized (PKW).
|
||||
*/
|

```
|
||||
|
||||
**B. Inbound Pickup Handler**
|
||||
**File:** `src/Form/Service/ParticipantPickupInboundFieldHandler.php`
|
||||
- Similar structure for inbound pickup
|
||||
- Field name: `pickupInbound`
|
||||
- Depends on `transportationInbound`
|
||||
- Uses `travel->pickupsFro`
|
||||
|
||||
#### 2.3 Parking Service Handler
|
||||
|
||||
**File:** `src/Form/Service/ParticipantParkingFieldHandler.php`
|
||||
|
||||
```php
|

```
|

#### 2.4 Field Options Provider Integration
|

### Phase 3: Conditional Field States & UX 🎨
|
||||
|
||||
#### 3.1 Service Sub-Type Condition
|
||||
|
||||
**File:** `src/Form/Service/Condition/ServiceSubTypeCondition.php`

|
||||
* additional services, etc.) to show/hide or enable/disable dependent fields
|

use App\BusProNet\Utility\DirectionMapper;
|
||||
use App\Form\Service\Condition\ServiceSubTypeCondition;
|
||||
|
||||
protected function registerFieldStateConditions(): void
|
||||
{
|
||||
// ... existing conditions
|
||||
|
||||
// Transportation-related field conditions
|
||||
|
||||
// Show outbound pickup only when transportation is BUS (hidden by default)
|
||||
$this->fieldStateConditions['pickupOutbound'] = [
|
||||
'hidden' => CompositeCondition::not(
|
||||
ServiceSubTypeCondition::equals('transportationOutbound', DirectionMapper::SUBTYPE_BUS_API)
|
||||
),
|
||||
];

```
|
||||
|
||||
## UX Design & User Experience 🎯
|
||||
|
||||
### Section Organization
|
||||
|
||||
**Transportation will be organized in logical sections:**
|
||||
|
||||
```html
|
||||
<!-- Optimized Transportation Layout -->
|
||||
<div class="mt-6 border-t pt-4">
|
||||
<h3 class="font-semibold text-lg mb-4">Anreise</h3>
|
||||
<div class="grid grid-cols-2 gap-4">
|
||||
<!-- Left Column: Outbound Transportation + Conditional Fields -->
|
||||
<div>
|
||||
{{ form_row(participant.transportationOutbound) }}
|
||||
|
||||
<!-- Conditional pickup (BUS) OR parking (PKW) - mutually exclusive -->
|
||||
{% if participant.pickupOutbound is defined %}
|
||||
<div class="mt-4">{{ form_row(participant.pickupOutbound) }}</div>
|
||||
{% endif %}
|
||||
{% if participant.parking is defined %}
|
||||
<div class="mt-4">{{ form_row(participant.parking) }}</div>
|
||||
{% endif %}
|
||||
</div>
|
||||
|
||||
<!-- Right Column: Inbound Transportation + Conditional Fields -->
|
||||
<div>
|
||||
{{ form_row(participant.transportationInbound) }}
|
||||
|
||||
{% if participant.pickupInbound is defined %}
|
||||
<div class="mt-4">{{ form_row(participant.pickupInbound) }}</div>
|
||||
{% endif %}
|
||||
</div>
|
||||
</div>
|
||||
</div>
|
||||
```
|
||||
|
||||
### Progressive Disclosure Features
|
||||
|
||||
1. **Smart Field Visibility:**
|
||||
- Pickup fields only appear when bus is selected
|
||||
- Parking only appears when PKW is selected
|
||||
- Smooth transitions using existing HTMX integration
|
||||
|
||||
2. **Visual Indicators:**
|
||||
- Transportation type icons (🚌 bus, 🚗 car)
|
||||
- Pricing with discount indicators
|
||||
- Availability warnings for limited services
|
||||
- Required field indicators
|
||||
|
||||
3. **Real-time Feedback:**

||||
## Pricing Integration 💰
|
||||
|
||||
### Transportation Service Pricing
|
||||
|
||||
- **Bus Services:** Standard pricing per direction
|
||||
- **PKW (Self-organized):** Often negative prices (discounts)
|
||||
- **Parking:** Additional cost for PKW travelers
|
||||
- **Combined Pricing:** Total transportation cost = outbound + inbound + parking
|
||||
|
||||
### Service Label Examples
|
||||
|
||||
- `🚌 Bus nach München (+€45,00)`
|
||||
- `🚗 Eigenanreise (-€20,00 Discount)`
|
||||
- `🅿️ Parkplatz Hotel (+€15,00)`
|
||||
- `🚌 Bus Hinfahrt (nur 3 verfügbar)`
|
||||
|
||||
## Data Flow & Validation 🔄

|
||||
4. **Pricing Calculation:** Total transportation cost calculated
|
||||
5. **Booking Summary Update:** Summary reflects all transportation selections
|
||||
|
||||
### Validation Rules
|
||||
|
||||
- **Transportation Required:** Both directions must have transportation
|
||||
- **Pickup Required:** When bus is selected, pickup is mandatory
|
||||
- **Parking Optional:** Available only with PKW transportation
|
||||
- **Service Availability:** Validate against available quantities
|
||||

## Key Implementation Highlights 🌟
|
||||
|
||||
### Transportation Type Mapping System
|
||||
|
||||
**Problem Solved:** BusProNet uses German abbreviations ('PKW') while internal code should use English terminology ('CAR') for consistency.
|
||||
|
||||
**Solution:** Enhanced `DirectionMapper` utility with bidirectional mapping:
|
||||
- **API Format:** `SUBTYPE_CAR_API = 'PKW'`, `SUBTYPE_BUS_API = 'BUS'`
|
||||
- **Internal Format:** `SUBTYPE_CAR = 'CAR'`, `SUBTYPE_BUS = 'BUS'`
|
||||
- **Mapping Methods:** `apiToInternal()`, `internalToApi()`, validation helpers
|
||||
|
||||
### Generic Service Sub-Type Condition
|
||||
|
||||
**Achievement:** Created reusable `ServiceSubTypeCondition` instead of transportation-specific logic:
|
||||
- Supports multiple operators: `equals`, `notEquals`, `in`, `notIn`
|
||||
- Works with any service field, not just transportation
|
||||
- Handles both API and internal sub-type values
|
||||
- Provides static factory methods for common use cases
|
||||
|
||||
### Data Model Optimizations
|
||||
|
||||
**Parking Field Simplification:**
|
||||
- **Problem:** Complex Service object storage for single checkbox
|
||||
- **Solution:** Changed to simple `bool $parking = false` in ParticipantDto
|
||||
- **Benefits:** Cleaner data model, simpler form processing, matches UX intent
|
||||
|
||||
**Form Processing Fixes:**
|
||||
- **Pickup Objects:** Fixed conversion from Pickup objects to IDs for form rendering
|
||||
- **Data Synchronization:** Enhanced registry to handle object-to-scalar conversion
|
||||
- **Type Safety:** Aligned form field types with DTO property types
|
||||
|
||||
### Template Layout Optimization
|
||||
|
||||
**Smart Space Utilization:**
|
||||
- **Mutually Exclusive Fields:** Pickup (BUS) and parking (PKW) share layout space
|
||||
- **Grid Layout:** Maintains clean 2-column transportation structure
|
||||
- **Visual Balance:** Eliminates empty space and improves UX
|
||||
- **Logical Grouping:** Related outbound fields stay together
|
||||
|
||||
### Conditional UX Logic
|
||||
|
||||
**Smart Field Visibility:**
|
||||
- **Pickup Fields:** Hidden by default, only visible when respective transportation is selected AND is BUS
|
||||
- **Parking Field:** Hidden by default, only visible when outbound transportation is selected AND is CAR (PKW)
|
||||
- **Default State:** All conditional fields start hidden until relevant transportation is chosen
|
||||
- **Template Optimization:** Outbound pickup and parking share the same layout space since they're mutually exclusive
|
||||
- Uses API constants since Service objects contain API values
|
||||
- Proper business logic: parking needed at destination for car arrivals
|
||||
|
||||
### Backward Compatibility
|
||||
|
||||
- Maintained all existing property names with deprecation notices
|
||||
- API integration continues using BusProNet's expected format
|
||||
- Internal code uses clean English naming
|
||||
- Seamless migration path for existing functionality
|
||||
|
||||
