Routing & Controllers

Minimum Version Requirement

This feature requires WhatsMarkSaaS v2.0.0 or higher. Ensure your installation meets this requirement before proceeding.

Overview

This guide covers route definition and controller implementation for custom modules. You will learn to create web routes, API endpoints, apply middleware, and handle requests with tenant-aware controllers.

---

Web Routes

Web routes are defined in Routes/web.php and handle browser-based requests.

Basic Route Definition

<?php

use Illuminate\Support\Facades\Route;
use Modules\OrderTracker\Http\Controllers\OrderTrackerController;

Route::middleware('web')->group(function () {
    Route::prefix('order-tracker')->group(function () {
        Route::get('/', [OrderTrackerController::class, 'index'])
            ->name('order-tracker.index');

        Route::get('/create', [OrderTrackerController::class, 'create'])
            ->name('order-tracker.create');

        Route::post('/store', [OrderTrackerController::class, 'store'])
            ->name('order-tracker.store');

        Route::get('/{id}', [OrderTrackerController::class, 'show'])
            ->name('order-tracker.show');

        Route::get('/{id}/edit', [OrderTrackerController::class, 'edit'])
            ->name('order-tracker.edit');

        Route::put('/{id}', [OrderTrackerController::class, 'update'])
            ->name('order-tracker.update');

        Route::delete('/{id}', [OrderTrackerController::class, 'destroy'])
            ->name('order-tracker.destroy');
    });
});

Route Naming Conventions

Routes must follow consistent naming patterns:

Pattern	Example	Description
{module}.index	order-tracker.index	List view
{module}.create	order-tracker.create	Create form
{module}.store	order-tracker.store	Store new record
{module}.show	order-tracker.show	Detail view
{module}.edit	order-tracker.edit	Edit form
{module}.update	order-tracker.update	Update record
{module}.destroy	order-tracker.destroy	Delete record

Route prefix convention:

Use kebab-case matching the module alias defined in module.json:

// module.json: "alias": "order-tracker"
Route::prefix('order-tracker')->group(function () {
    // Routes here
});

---

API Routes

API routes are defined in Routes/api.php and handle JSON-based API requests.

Basic API Route Definition

<?php

use Illuminate\Support\Facades\Route;
use Modules\OrderTracker\Http\Controllers\Api\OrderApiController;

Route::middleware('api')->prefix('api')->group(function () {
    Route::prefix('order-tracker')->group(function () {

        // Public API endpoints (no authentication)
        Route::get('/status', [OrderApiController::class, 'status']);

        // Protected API endpoints (require authentication)
        Route::middleware('auth:sanctum')->group(function () {
            Route::get('/orders', [OrderApiController::class, 'index']);
            Route::get('/orders/{id}', [OrderApiController::class, 'show']);
            Route::post('/orders', [OrderApiController::class, 'store']);
            Route::put('/orders/{id}', [OrderApiController::class, 'update']);
            Route::delete('/orders/{id}', [OrderApiController::class, 'destroy']);
        });
    });
});

API Versioning

Implement API versioning using route prefixes:

Route::middleware('api')->prefix('api')->group(function () {
    // v1 routes
    Route::prefix('v1/order-tracker')->group(function () {
        Route::get('/orders', [OrderApiV1Controller::class, 'index']);
    });

    // v2 routes
    Route::prefix('v2/order-tracker')->group(function () {
        Route::get('/orders', [OrderApiV2Controller::class, 'index']);
    });
});

---

Middleware Application

Common Middleware

Middleware	Purpose	Usage
web	Browser requests, CSRF, sessions	Required for all web routes
api	API requests, JSON responses	Required for all API routes
auth	User authentication	Protect authenticated routes
auth:sanctum	API token authentication	Protect API endpoints
tenant	Tenant context verification	Ensure tenant isolation

Authentication Middleware

Web authentication:

Route::middleware(['web', 'auth'])->group(function () {
    Route::prefix('order-tracker')->group(function () {
        Route::get('/', [OrderTrackerController::class, 'index'])
            ->name('order-tracker.index');
    });
});

API authentication:

Route::middleware(['api', 'auth:sanctum'])->prefix('api')->group(function () {
    Route::prefix('order-tracker')->group(function () {
        Route::get('/orders', [OrderApiController::class, 'index']);
    });
});

Tenant Middleware

Apply tenant middleware to ensure tenant-scoped operations:

Route::middleware(['web', 'auth', 'tenant'])->group(function () {
    Route::prefix('order-tracker')->group(function () {
        Route::get('/', [OrderTrackerController::class, 'index'])
            ->name('order-tracker.index');
    });
});

Custom Middleware

Create custom middleware in Http/Middleware/:

<?php

namespace Modules\OrderTracker\Http\Middleware;

use Closure;
use Illuminate\Http\Request;
use Symfony\Component\HttpFoundation\Response;

class CheckOrderPermission
{
    /**
     * Handle an incoming request.
     *
     * @param  \Closure(\Illuminate\Http\Request): (\Symfony\Component\HttpFoundation\Response)  $next
     */
    public function handle(Request $request, Closure $next): Response
    {
        if (! $request->user()->can('manage-orders')) {
            abort(403, 'Unauthorized action.');
        }

        return $next($request);
    }
}

Register custom middleware:

Route::middleware(['web', 'auth', CheckOrderPermission::class])->group(function () {
    Route::prefix('order-tracker')->group(function () {
        // Protected routes
    });
});

---

Controllers

Basic Controller Structure

<?php

namespace Modules\OrderTracker\Http\Controllers;

use Illuminate\Http\Request;
use Illuminate\Routing\Controller;
use Modules\OrderTracker\Models\Order;

class OrderTrackerController extends Controller
{
    /**
     * Display a listing of orders.
     */
    public function index()
    {
        $orders = Order::where('tenant_id', tenant_id())
            ->latest()
            ->paginate(20);

        return view('ordertracker::index', compact('orders'));
    }

    /**
     * Show the form for creating a new order.
     */
    public function create()
    {
        return view('ordertracker::create');
    }

    /**
     * Store a newly created order.
     */
    public function store(Request $request)
    {
        $validated = $request->validate([
            'order_number' => 'required|string|unique:orders',
            'total' => 'required|numeric|min:0',
            'status' => 'required|string|in:pending,processing,completed',
        ]);

        $order = Order::create([
            'tenant_id' => tenant_id(),
            'order_number' => $validated['order_number'],
            'total' => $validated['total'],
            'status' => $validated['status'],
        ]);

        return redirect()
            ->route('order-tracker.show', $order->id)
            ->with('success', 'Order created successfully.');
    }

    /**
     * Display the specified order.
     */
    public function show(int $id)
    {
        $order = Order::where('tenant_id', tenant_id())
            ->findOrFail($id);

        return view('ordertracker::show', compact('order'));
    }

    /**
     * Show the form for editing the specified order.
     */
    public function edit(int $id)
    {
        $order = Order::where('tenant_id', tenant_id())
            ->findOrFail($id);

        return view('ordertracker::edit', compact('order'));
    }

    /**
     * Update the specified order.
     */
    public function update(Request $request, int $id)
    {
        $order = Order::where('tenant_id', tenant_id())
            ->findOrFail($id);

        $validated = $request->validate([
            'total' => 'required|numeric|min:0',
            'status' => 'required|string|in:pending,processing,completed',
        ]);

        $order->update($validated);

        return redirect()
            ->route('order-tracker.show', $order->id)
            ->with('success', 'Order updated successfully.');
    }

    /**
     * Remove the specified order.
     */
    public function destroy(int $id)
    {
        $order = Order::where('tenant_id', tenant_id())
            ->findOrFail($id);

        $order->delete();

        return redirect()
            ->route('order-tracker.index')
            ->with('success', 'Order deleted successfully.');
    }
}

API Controller Structure

<?php

namespace Modules\OrderTracker\Http\Controllers\Api;

use Illuminate\Http\Request;
use Illuminate\Http\JsonResponse;
use Illuminate\Routing\Controller;
use Modules\OrderTracker\Models\Order;

class OrderApiController extends Controller
{
    /**
     * Display a listing of orders.
     */
    public function index(): JsonResponse
    {
        $orders = Order::where('tenant_id', tenant_id())
            ->latest()
            ->paginate(20);

        return response()->json($orders);
    }

    /**
     * Store a newly created order.
     */
    public function store(Request $request): JsonResponse
    {
        $validated = $request->validate([
            'order_number' => 'required|string|unique:orders',
            'total' => 'required|numeric|min:0',
            'status' => 'required|string|in:pending,processing,completed',
        ]);

        $order = Order::create([
            'tenant_id' => tenant_id(),
            'order_number' => $validated['order_number'],
            'total' => $validated['total'],
            'status' => $validated['status'],
        ]);

        return response()->json($order, 201);
    }

    /**
     * Display the specified order.
     */
    public function show(int $id): JsonResponse
    {
        $order = Order::where('tenant_id', tenant_id())
            ->findOrFail($id);

        return response()->json($order);
    }

    /**
     * Update the specified order.
     */
    public function update(Request $request, int $id): JsonResponse
    {
        $order = Order::where('tenant_id', tenant_id())
            ->findOrFail($id);

        $validated = $request->validate([
            'total' => 'numeric|min:0',
            'status' => 'string|in:pending,processing,completed',
        ]);

        $order->update($validated);

        return response()->json($order);
    }

    /**
     * Remove the specified order.
     */
    public function destroy(int $id): JsonResponse
    {
        $order = Order::where('tenant_id', tenant_id())
            ->findOrFail($id);

        $order->delete();

        return response()->json(null, 204);
    }
}

Request Validation

Form Request Classes

Create dedicated request validation classes for complex validation logic:

<?php

namespace Modules\OrderTracker\Http\Requests;

use Illuminate\Foundation\Http\FormRequest;

class StoreOrderRequest extends FormRequest
{
    /**
     * Determine if the user is authorized to make this request.
     */
    public function authorize(): bool
    {
        return $this->user()->can('create-orders');
    }

    /**
     * Get the validation rules that apply to the request.
     *
     * @return array<string, \Illuminate\Contracts\Validation\ValidationRule|array<mixed>|string>
     */
    public function rules(): array
    {
        return [
            'order_number' => 'required|string|unique:orders',
            'total' => 'required|numeric|min:0',
            'status' => 'required|string|in:pending,processing,completed',
            'items' => 'required|array|min:1',
            'items.*.product_id' => 'required|exists:products,id',
            'items.*.quantity' => 'required|integer|min:1',
            'items.*.price' => 'required|numeric|min:0',
        ];
    }

    /**
     * Get custom messages for validator errors.
     */
    public function messages(): array
    {
        return [
            'order_number.required' => 'Order number is required.',
            'items.required' => 'Order must contain at least one item.',
        ];
    }
}

Usage in controller:

use Modules\OrderTracker\Http\Requests\StoreOrderRequest;

public function store(StoreOrderRequest $request)
{
    $validated = $request->validated();

    $order = Order::create([
        'tenant_id' => tenant_id(),
        ...$validated
    ]);

    return redirect()
        ->route('order-tracker.show', $order->id)
        ->with('success', 'Order created successfully.');
}

---

Response Patterns

Web Responses

Redirect with flash message:

return redirect()
    ->route('order-tracker.index')
    ->with('success', 'Order created successfully.');

Redirect with errors:

return redirect()
    ->back()
    ->withErrors(['error' => 'Unable to create order.'])
    ->withInput();

View response:

return view('ordertracker::index', [
    'orders' => $orders,
    'statistics' => $statistics,
]);

API Responses

Success response (200):

return response()->json([
    'message' => 'Order retrieved successfully.',
    'data' => $order,
], 200);

Created response (201):

return response()->json([
    'message' => 'Order created successfully.',
    'data' => $order,
], 201);

No content response (204):

return response()->json(null, 204);

Error response (4xx):

return response()->json([
    'message' => 'Order not found.',
    'errors' => [],
], 404);

Validation error response (422):

return response()->json([
    'message' => 'Validation failed.',
    'errors' => $validator->errors(),
], 422);

---

Tenant-Aware Operations

Critical Tenant Scoping

All database queries must be scoped to the current tenant:

//  Correct - tenant-scoped query
$orders = Order::where('tenant_id', tenant_id())
    ->get();

//  Incorrect - exposes all tenant data
$orders = Order::all();

Using Tenant Helper

use function App\Helpers\tenant_id;

public function index()
{
    $tenantId = tenant_id();

    $orders = Order::where('tenant_id', $tenantId)
        ->latest()
        ->paginate(20);

    return view('ordertracker::index', compact('orders'));
}

---

Route Caching

Generate Route Cache

php artisan route:cache

Clear Route Cache

php artisan route:clear

Important: Clear route cache after adding or modifying routes.

---

Testing Routes

List All Routes

php artisan route:list

Filter Module Routes

php artisan route:list --path=order-tracker

Check Specific Route

php artisan route:list --name=order-tracker.index

---

Next Steps

• Views & Translations - Create Blade templates and translations
• Hooks & Events - Integrate with hook system
• Helper Functions - Use module utilities
