Enhanced Enum Processing with Laravel's Default Parameter Support

Laravel's request enum handling has been improved with built-in default value support, streamlining enum validation and fallback logic in your applications.

Previously, handling missing or invalid enum values required additional code to provide fallbacks. The updated enum method now accepts a third parameter for default values:

$reportFormat = request()->enum('format', ReportFormat::class, ReportFormat::PDF);
 
$sortDirection = request()->enum('direction', SortDirection::class, SortDirection::Ascending);

This enhancement reduces boilerplate code and makes enum handling more declarative throughout your application logic.

class ReportController extends Controller
{
    public function generateSalesReport(Request $request)
    {
        $configuration = [
            'output_format' => $request->enum('format', OutputFormat::class, OutputFormat::Excel),
            'time_range' => $request->enum('range', TimeRange::class, TimeRange::LastMonth),
            'detail_level' => $request->enum('detail', DetailLevel::class, DetailLevel::Summary),
            'export_type' => $request->enum('export', ExportType::class, ExportType::Download)
        ];
 
        return $this->buildReport($configuration);
    }
 
    public function configureNotifications(Request $request)
    {
        $settings = [
            'delivery_method' => $request->enum('method', DeliveryMethod::class, DeliveryMethod::Email),
            'priority_level' => $request->enum('priority', Priority::class, Priority::Normal),
            'frequency' => $request->enum('frequency', Frequency::class, Frequency::Weekly),
            'format_type' => $request->enum('format', NotificationFormat::class, NotificationFormat::HTML)
        ];
 
        $this->saveNotificationSettings($settings);
 
        return response()->json(['status' => 'updated', 'settings' => $settings]);
    }
 
    private function buildReport(array $config)
    {
        $reportBuilder = new SalesReportBuilder();
 
        return $reportBuilder
            ->setFormat($config['output_format'])
            ->setTimeRange($config['time_range'])
            ->setDetailLevel($config['detail_level'])
            ->setExportType($config['export_type'])
            ->generate();
    }
}

The default parameter feature eliminates conditional logic and makes enum-based request handling more predictable and maintainable across your Laravel applications.
