Controllers

Let’s take a look at an example of a basic controller. Note that the controller extends the base controller class included with Laravel: App\Http\Controllers\Controller:

You can define a route to this controller method like so:

  1. use App\Http\Controllers\UserController; Route::get('/user/{id}', [UserController::class, 'show']);

When an incoming request matches the specified route URI, the show method on the App\Http\Controllers\UserController class will be invoked and the route parameters will be passed to the method.

Single Action Controllers

If a controller action is particularly complex, you might find it convenient to dedicate an entire controller class to that single action. To accomplish this, you may define a single __invoke method within the controller:

  1. <?php namespace App\Http\Controllers; use App\Models\User;use Illuminate\Http\Response; class ProvisionServer extends Controller{    /**     * Provision a new web server.     */    public function __invoke()    {        // ...    }}

When registering routes for single action controllers, you do not need to specify a controller method. Instead, you may simply pass the name of the controller to the router:

  1. use App\Http\Controllers\ProvisionServer; Route::post('/server', ProvisionServer::class);

You may generate an invokable controller by using the --invokable option of the make:controller Artisan command:

  1. php artisan make:controller ProvisionServer --invokable

Middleware may be assigned to the controller’s routes in your route files:

  1. Route::get('profile', [UserController::class, 'show'])->middleware('auth');

Or, you may find it convenient to specify middleware within your controller’s constructor. Using the middleware method within your controller’s constructor, you can assign middleware to the controller’s actions:

  1. class UserController extends Controller{    /**     * Instantiate a new controller instance.     */    public function __construct()    {        $this->middleware('auth');        $this->middleware('log')->only('index');        $this->middleware('subscribed')->except('store');    }}

Controllers also allow you to register middleware using a closure. This provides a convenient way to define an inline middleware for a single controller without defining an entire middleware class:

  1. use Closure;use Illuminate\Http\Request; $this->middleware(function (Request $request, Closure $next) {    return $next($request);});

If you think of each Eloquent model in your application as a “resource”, it is typical to perform the same sets of actions against each resource in your application. For example, imagine your application contains a Photo model and a Movie model. It is likely that users can create, read, update, or delete these resources.

Because of this common use case, Laravel resource routing assigns the typical create, read, update, and delete (“CRUD”) routes to a controller with a single line of code. To get started, we can use the make:controller Artisan command’s --resource option to quickly create a controller to handle these actions:

  1. php artisan make:controller PhotoController --resource

This command will generate a controller at app/Http/Controllers/PhotoController.php. The controller will contain a method for each of the available resource operations. Next, you may register a resource route that points to the controller:

  1. use App\Http\Controllers\PhotoController; Route::resource('photos', PhotoController::class);

This single route declaration creates multiple routes to handle a variety of actions on the resource. The generated controller will already have methods stubbed for each of these actions. Remember, you can always get a quick overview of your application’s routes by running the route:list Artisan command.

You may even register many resource controllers at once by passing an array to the resources method:

    Actions Handled By Resource Controller

    Customizing Missing Model Behavior

    Typically, a 404 HTTP response will be generated if an implicitly bound resource model is not found. However, you may customize this behavior by calling the missing method when defining your resource route. The missing method accepts a closure that will be invoked if an implicitly bound model can not be found for any of the resource’s routes:

    1. use App\Http\Controllers\PhotoController;use Illuminate\Http\Request;use Illuminate\Support\Facades\Redirect; Route::resource('photos', PhotoController::class)        ->missing(function (Request $request) {            return Redirect::route('photos.index');        });

    Soft Deleted Models

    1. use App\Http\Controllers\PhotoController; Route::resource('photos', PhotoController::class)->withTrashed();

    Calling withTrashed with no arguments will allow soft deleted models for the show, edit, and update resource routes. You may specify a subset of these routes by passing an array to the method:

    Specifying The Resource Model

    If you are using route model binding and would like the resource controller’s methods to type-hint a model instance, you may use the --model option when generating the controller:

    1. php artisan make:controller PhotoController --model=Photo --resource

    Generating Form Requests

    You may provide the --requests option when generating a resource controller to instruct Artisan to generate form request classes for the controller’s storage and update methods:

    1. php artisan make:controller PhotoController --model=Photo --resource --requests

    Partial Resource Routes

    When declaring a resource route, you may specify a subset of actions the controller should handle instead of the full set of default actions:

    1. use App\Http\Controllers\PhotoController; Route::resource('photos', PhotoController::class)->only([    'index', 'show']); Route::resource('photos', PhotoController::class)->except([    'create', 'store', 'update', 'destroy']);

    API Resource Routes

    When declaring resource routes that will be consumed by APIs, you will commonly want to exclude routes that present HTML templates such as create and edit. For convenience, you may use the apiResource method to automatically exclude these two routes:

    1. use App\Http\Controllers\PhotoController; Route::apiResource('photos', PhotoController::class);

    You may register many API resource controllers at once by passing an array to the apiResources method:

    1. use App\Http\Controllers\PhotoController;use App\Http\Controllers\PostController; Route::apiResources([    'photos' => PhotoController::class,    'posts' => PostController::class,]);

    To quickly generate an API resource controller that does not include the create or edit methods, use the --api switch when executing the make:controller command:

    1. php artisan make:controller PhotoController --api

    Sometimes you may need to define routes to a nested resource. For example, a photo resource may have multiple comments that may be attached to the photo. To nest the resource controllers, you may use “dot” notation in your route declaration:

    1. use App\Http\Controllers\PhotoCommentController; Route::resource('photos.comments', PhotoCommentController::class);

    This route will register a nested resource that may be accessed with URIs like the following:

    1. /photos/{photo}/comments/{comment}

    Scoping Nested Resources

    Laravel’s feature can automatically scope nested bindings such that the resolved child model is confirmed to belong to the parent model. By using the scoped method when defining your nested resource, you may enable automatic scoping as well as instruct Laravel which field the child resource should be retrieved by. For more information on how to accomplish this, please see the documentation on scoping resource routes.

    Shallow Nesting

    Often, it is not entirely necessary to have both the parent and the child IDs within a URI since the child ID is already a unique identifier. When using unique identifiers such as auto-incrementing primary keys to identify your models in URI segments, you may choose to use “shallow nesting”:

    1. use App\Http\Controllers\CommentController; Route::resource('photos.comments', CommentController::class)->shallow();

    This route definition will define the following routes:

    Naming Resource Routes

    By default, all resource controller actions have a route name; however, you can override these names by passing a names array with your desired route names:

    1. use App\Http\Controllers\PhotoController; Route::resource('photos', PhotoController::class)->names([    'create' => 'photos.build']);

    Naming Resource Route Parameters

    By default, Route::resource will create the route parameters for your resource routes based on the “singularized” version of the resource name. You can easily override this on a per resource basis using the parameters method. The array passed into the parameters method should be an associative array of resource names and parameter names:

    1. use App\Http\Controllers\AdminUserController; Route::resource('users', AdminUserController::class)->parameters([    'users' => 'admin_user']);

    The example above generates the following URI for the resource’s show route:

    1. /users/{admin_user}

    Laravel’s feature can automatically scope nested bindings such that the resolved child model is confirmed to belong to the parent model. By using the scoped method when defining your nested resource, you may enable automatic scoping as well as instruct Laravel which field the child resource should be retrieved by:

    This route will register a scoped nested resource that may be accessed with URIs like the following:

    1. /photos/{photo}/comments/{comment:slug}

    Localizing Resource URIs

    By default, Route::resource will create resource URIs using English verbs and plural rules. If you need to localize the create and edit action verbs, you may use the method. This may be done at the beginning of the boot method within your application’s App\Providers\RouteServiceProvider:

    1. /** * Define your route model bindings, pattern filters, etc. */public function boot(): void{    Route::resourceVerbs([        'create' => 'crear',        'edit' => 'editar',    ]);     // ...}

    Laravel’s pluralizer supports . Once the verbs and pluralization language have been customized, a resource route registration such as Route::resource('publicacion', PublicacionController::class) will produce the following URIs:

    1. /publicacion/crear /publicacion/{publicaciones}/editar

    Supplementing Resource Controllers

    If you need to add additional routes to a resource controller beyond the default set of resource routes, you should define those routes before your call to the Route::resource method; otherwise, the routes defined by the resource method may unintentionally take precedence over your supplemental routes:

    1. use App\Http\Controller\PhotoController; Route::get('/photos/popular', [PhotoController::class, 'popular']);Route::resource('photos', PhotoController::class);

    Sometimes, your application will have resources that may only have a single instance. For example, a user’s “profile” can be edited or updated, but a user may not have more than one “profile”. Likewise, an image may have a single “thumbnail”. These resources are called “singleton resources”, meaning one and only one instance of the resource may exist. In these scenarios, you may register a “singleton” resource controller:

    1. use App\Http\Controllers\ProfileController;use Illuminate\Support\Facades\Route; Route::singleton('profile', ProfileController::class);

    The singleton resource definition above will register the following routes. As you can see, “creation” routes are not registered for singleton resources, and the registered routes do not accept an identifier since only one instance of the resource may exist:

    Singleton resources may also be nested within a standard resource:

    1. Route::singleton('photos.thumbnail', ThumbnailController::class);

    In this example, the photos resource would receive all of the standard resource routes; however, the thumbnail resource would be a singleton resource with the following routes:

    Creatable Singleton Resources

    Occasionally, you may want to define creation and storage routes for a singleton resource. To accomplish this, you may invoke the creatable method when registering the singleton resource route:

    1. Route::singleton('photos.thumbnail', ThumbnailController::class)->creatable();

    In this example, the following routes will be registered. As you can see, a DELETE route will also be registered for creatable singleton resources:

    If you would like Laravel to register the DELETE route for a singleton resource but not register the creation or storage routes, you may utilize the destroyable method:

    1. Route::singleton(...)->destroyable();

    API Singleton Resources

    The apiSingleton method may be used to register a singleton resource that will be manipulated via an API, thus rendering the create and edit routes unnecessary:

    1. Route::apiSingleton('profile', ProfileController::class);

    Of course, API singleton resources may also be creatable, which will register store and destroy routes for the resource:

    1. Route::apiSingleton('photos.thumbnail', ProfileController::class)->creatable();

    Constructor Injection

    The Laravel is used to resolve all Laravel controllers. As a result, you are able to type-hint any dependencies your controller may need in its constructor. The declared dependencies will automatically be resolved and injected into the controller instance:

    1. <?php namespace App\Http\Controllers; use App\Repositories\UserRepository; class UserController extends Controller{    /**     * Create a new controller instance.     */    public function __construct(        protected UserRepository $users,    ) {}}

    Method Injection

    In addition to constructor injection, you may also type-hint dependencies on your controller’s methods. A common use-case for method injection is injecting the Illuminate\Http\Request instance into your controller methods:

      If your controller method is also expecting input from a route parameter, list your route arguments after your other dependencies. For example, if your route is defined like so:

      You may still type-hint the Illuminate\Http\Request and access your id parameter by defining your controller method as follows:
