🔧 Service Architecture Details

Field Handler System ✅ COMPREHENSIVE

Implemented Handlers (15+ specialized processors):

├── ParticipantTransportationOutboundFieldHandler     # Bus/car transport selection
├── ParticipantTransportationInboundFieldHandler      # Return transport
├── ParticipantPickupOutboundFieldHandler             # Pickup location services
├── ParticipantPickupInboundFieldHandler              # Return pickup services
├── ParticipantParkingFieldHandler                    # Self-organized parking
├── ParticipantBoardFieldHandler                      # Meal plan selection
├── ParticipantSkiPassFieldHandler                    # Ski pass options
├── ParticipantCoursesFieldHandler                    # Activity courses
├── ParticipantRentalsFieldHandler                    # Equipment rentals
├── ParticipantAdditionalServicesFieldHandler         # Extra services
├── ParticipantAssignedRoomFieldHandler               # Room assignments
├── ParticipantDateOfBirthFieldHandler                # Age processing
├── ParticipantRemarksRoomFieldHandler                # Special requests
└── [Custom handlers easily extensible]

Handler Capabilities:

• Dependency resolution with circular dependency detection
• Conditional processing based on participant data
• Service registration via Symfony's service container
• Priority-based processing order
• Type-safe data handling with proper validation

Conditional Field State System ✅ ADVANCED

Available Conditions:

• AgeRangeCondition: Age-based field behavior
• FieldValueCondition: Field interdependency logic
• ServiceSubTypeCondition: Service-specific conditions
• CompositeCondition: Complex AND/OR/NOT logic
• Custom conditions easily extensible

Field States:

• readonly: Field visible but not editable
• disabled: Field interaction disabled
• required: Field becomes mandatory
• hidden: Field not displayed (CSS-based)

Real-world Examples:

// Age-based service restriction
$this->fieldStateConditions['advancedSkiCourse'] = [
    'hidden' => new AgeRangeCondition(null, 15), // Hide for under 15
    'required' => FieldValueCondition::equals('skillLevel', 'expert'),
];

// Transportation mutual exclusivity
$this->fieldStateConditions['pickupLocation'] = [
    'hidden' => ServiceSubTypeCondition::equals('transportationOutbound', 'CAR'),
];

$this->fieldStateConditions['parkingRequired'] = [
    'hidden' => ServiceSubTypeCondition::notEquals('transportationOutbound', 'CAR'),
];
