## Introduction

Instead of defining all of your request handling logic as closures in your
route files, you may wish to organize this behavior using "controller"
classes. Controllers can group related request handling logic into a single
class. For example, a `UserController` class might handle all incoming
requests related to users, including showing, creating, updating, and deleting
users. By default, controllers are stored in the `app/Http/Controllers`
directory.

## Writing Controllers

### Basic Controllers

To quickly generate a new controller, you may run the `make:controller`
Artisan command. By default, all of the controllers for your application are
stored in the `app/Http/Controllers` directory:

    
    
    1php artisan make:controller UserController
    
    
    php artisan make:controller UserController

Let's take a look at an example of a basic controller. A controller may have
any number of public methods which will respond to incoming HTTP requests:

    
    
     1<?php
    
     2 
    
     3namespace App\Http\Controllers;
    
     4 
    
     5use App\Models\User;
    
     6use Illuminate\View\View;
    
     7 
    
     8class UserController extends Controller
    
     9{
    
    10    /**
    
    11     * Show the profile for a given user.
    
    12     */
    
    13    public function show(string $id): View
    
    14    {
    
    15        return view('user.profile', [
    
    16            'user' => User::findOrFail($id)
    
    17        ]);
    
    18    }
    
    19}
    
    
    <?php
    
    namespace App\Http\Controllers;
    
    use App\Models\User;
    use Illuminate\View\View;
    
    class UserController extends Controller
    {
        /**
         * Show the profile for a given user.
         */
        public function show(string $id): View
        {
            return view('user.profile', [
                'user' => User::findOrFail($id)
            ]);
        }
    }

Once you have written a controller class and method, you may define a route to
the controller method like so:

    
    
    1use App\Http\Controllers\UserController;
    
    2 
    
    3Route::get('/user/{id}', [UserController::class, 'show']);
    
    
    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.

Controllers are not **required** to extend a base class. However, it is
sometimes convenient to extend a base controller class that contains methods
that should be shared across all of your controllers.

### 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
    
     2 
    
     3namespace App\Http\Controllers;
    
     4 
    
     5class ProvisionServer extends Controller
    
     6{
    
     7    /**
    
     8     * Provision a new web server.
    
     9     */
    
    10    public function __invoke()
    
    11    {
    
    12        // ...
    
    13    }
    
    14}
    
    
    <?php
    
    namespace App\Http\Controllers;
    
    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:

    
    
    1use App\Http\Controllers\ProvisionServer;
    
    2 
    
    3Route::post('/server', ProvisionServer::class);
    
    
    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:

    
    
    1php artisan make:controller ProvisionServer --invokable
    
    
    php artisan make:controller ProvisionServer --invokable

Controller stubs may be customized using [stub
publishing](/docs/12.x/artisan#stub-customization).

## Controller Middleware

[Middleware](/docs/12.x/middleware) may be assigned to the controller's routes
in your route files:

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

Or, you may find it convenient to specify middleware within your controller
class. To do so, your controller should implement the `HasMiddleware`
interface, which dictates that the controller should have a static
`middleware` method. From this method, you may return an array of middleware
that should be applied to the controller's actions:

    
    
     1<?php
    
     2 
    
     3namespace App\Http\Controllers;
    
     4 
    
     5use Illuminate\Routing\Controllers\HasMiddleware;
    
     6use Illuminate\Routing\Controllers\Middleware;
    
     7 
    
     8class UserController extends Controller implements HasMiddleware
    
     9{
    
    10    /**
    
    11     * Get the middleware that should be assigned to the controller.
    
    12     */
    
    13    public static function middleware(): array
    
    14    {
    
    15        return [
    
    16            'auth',
    
    17            new Middleware('log', only: ['index']),
    
    18            new Middleware('subscribed', except: ['store']),
    
    19        ];
    
    20    }
    
    21 
    
    22    // ...
    
    23}
    
    
    <?php
    
    namespace App\Http\Controllers;
    
    use Illuminate\Routing\Controllers\HasMiddleware;
    use Illuminate\Routing\Controllers\Middleware;
    
    class UserController extends Controller implements HasMiddleware
    {
        /**
         * Get the middleware that should be assigned to the controller.
         */
        public static function middleware(): array
        {
            return [
                'auth',
                new Middleware('log', only: ['index']),
                new Middleware('subscribed', except: ['store']),
            ];
        }
    
        // ...
    }

You may also define controller middleware as closures, which provides a
convenient way to define an inline middleware without writing an entire
middleware class:

    
    
     1use Closure;
    
     2use Illuminate\Http\Request;
    
     3 
    
     4/**
    
     5 * Get the middleware that should be assigned to the controller.
    
     6 */
    
     7public static function middleware(): array
    
     8{
    
     9    return [
    
    10        function (Request $request, Closure $next) {
    
    11            return $next($request);
    
    12        },
    
    13    ];
    
    14}
    
    
    use Closure;
    use Illuminate\Http\Request;
    
    /**
     * Get the middleware that should be assigned to the controller.
     */
    public static function middleware(): array
    {
        return [
            function (Request $request, Closure $next) {
                return $next($request);
            },
        ];
    }

## Resource Controllers

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:

    
    
    1php artisan make:controller PhotoController --resource
    
    
    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:

    
    
    1use App\Http\Controllers\PhotoController;
    
    2 
    
    3Route::resource('photos', PhotoController::class);
    
    
    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:

    
    
    1Route::resources([
    
    2    'photos' => PhotoController::class,
    
    3    'posts' => PostController::class,
    
    4]);
    
    
    Route::resources([
        'photos' => PhotoController::class,
        'posts' => PostController::class,
    ]);

The `softDeletableResources` method registers many resources controllers that
all use the `withTrashed` method:

    
    
    1Route::softDeletableResources([
    
    2    'photos' => PhotoController::class,
    
    3    'posts' => PostController::class,
    
    4]);
    
    
    Route::softDeletableResources([
        'photos' => PhotoController::class,
        'posts' => PostController::class,
    ]);

#### Actions Handled by Resource Controllers

Verb | URI | Action | Route Name  
---|---|---|---  
GET | `/photos` | index | photos.index  
GET | `/photos/create` | create | photos.create  
POST | `/photos` | store | photos.store  
GET | `/photos/{photo}` | show | photos.show  
GET | `/photos/{photo}/edit` | edit | photos.edit  
PUT/PATCH | `/photos/{photo}` | update | photos.update  
DELETE | `/photos/{photo}` | destroy | photos.destroy  
  
#### 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
cannot be found for any of the resource's routes:

    
    
    1use App\Http\Controllers\PhotoController;
    
    2use Illuminate\Http\Request;
    
    3use Illuminate\Support\Facades\Redirect;
    
    4 
    
    5Route::resource('photos', PhotoController::class)
    
    6    ->missing(function (Request $request) {
    
    7        return Redirect::route('photos.index');
    
    8    });
    
    
    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

Typically, implicit model binding will not retrieve models that have been
[soft deleted](/docs/12.x/eloquent#soft-deleting), and will instead return a
404 HTTP response. However, you can instruct the framework to allow soft
deleted models by invoking the `withTrashed` method when defining your
resource route:

    
    
    1use App\Http\Controllers\PhotoController;
    
    2 
    
    3Route::resource('photos', PhotoController::class)->withTrashed();
    
    
    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 `withTrashed` method:

    
    
    1Route::resource('photos', PhotoController::class)->withTrashed(['show']);
    
    
    Route::resource('photos', PhotoController::class)->withTrashed(['show']);

#### Specifying the Resource Model

If you are using [route model binding](/docs/12.x/routing#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:

    
    
    1php artisan make:controller PhotoController --model=Photo --resource
    
    
    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](/docs/12.x/validation#form-request-validation) for the controller's
storage and update methods:

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

    
    
    1use App\Http\Controllers\PhotoController;
    
    2 
    
    3Route::resource('photos', PhotoController::class)->only([
    
    4    'index', 'show'
    
    5]);
    
    6 
    
    7Route::resource('photos', PhotoController::class)->except([
    
    8    'create', 'store', 'update', 'destroy'
    
    9]);
    
    
    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:

    
    
    1use App\Http\Controllers\PhotoController;
    
    2 
    
    3Route::apiResource('photos', PhotoController::class);
    
    
    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:

    
    
    1use App\Http\Controllers\PhotoController;
    
    2use App\Http\Controllers\PostController;
    
    3 
    
    4Route::apiResources([
    
    5    'photos' => PhotoController::class,
    
    6    'posts' => PostController::class,
    
    7]);
    
    
    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:

    
    
    1php artisan make:controller PhotoController --api
    
    
    php artisan make:controller PhotoController --api

### Nested Resources

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:

    
    
    1use App\Http\Controllers\PhotoCommentController;
    
    2 
    
    3Route::resource('photos.comments', PhotoCommentController::class);
    
    
    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}
    
    
    /photos/{photo}/comments/{comment}

#### Scoping Nested Resources

Laravel's [implicit model binding](/docs/12.x/routing#implicit-model-binding-
scoping) 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":

    
    
    1use App\Http\Controllers\CommentController;
    
    2 
    
    3Route::resource('photos.comments', CommentController::class)->shallow();
    
    
    use App\Http\Controllers\CommentController;
    
    Route::resource('photos.comments', CommentController::class)->shallow();

This route definition will define the following routes:

Verb | URI | Action | Route Name  
---|---|---|---  
GET | `/photos/{photo}/comments` | index | photos.comments.index  
GET | `/photos/{photo}/comments/create` | create | photos.comments.create  
POST | `/photos/{photo}/comments` | store | photos.comments.store  
GET | `/comments/{comment}` | show | comments.show  
GET | `/comments/{comment}/edit` | edit | comments.edit  
PUT/PATCH | `/comments/{comment}` | update | comments.update  
DELETE | `/comments/{comment}` | destroy | comments.destroy  
  
### 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:

    
    
    1use App\Http\Controllers\PhotoController;
    
    2 
    
    3Route::resource('photos', PhotoController::class)->names([
    
    4    'create' => 'photos.build'
    
    5]);
    
    
    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:

    
    
    1use App\Http\Controllers\AdminUserController;
    
    2 
    
    3Route::resource('users', AdminUserController::class)->parameters([
    
    4    'users' => 'admin_user'
    
    5]);
    
    
    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}
    
    
    /users/{admin_user}

### Scoping Resource Routes

Laravel's [scoped implicit model binding](/docs/12.x/routing#implicit-model-
binding-scoping) 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:

    
    
    1use App\Http\Controllers\PhotoCommentController;
    
    2 
    
    3Route::resource('photos.comments', PhotoCommentController::class)->scoped([
    
    4    'comment' => 'slug',
    
    5]);
    
    
    use App\Http\Controllers\PhotoCommentController;
    
    Route::resource('photos.comments', PhotoCommentController::class)->scoped([
        'comment' => 'slug',
    ]);

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

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

When using a custom keyed implicit binding as a nested route parameter,
Laravel will automatically scope the query to retrieve the nested model by its
parent using conventions to guess the relationship name on the parent. In this
case, it will be assumed that the `Photo` model has a relationship named
`comments` (the plural of the route parameter name) which can be used to
retrieve the `Comment` model.

### 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 `Route::resourceVerbs` method. This may be done at the
beginning of the `boot` method within your application's
`App\Providers\AppServiceProvider`:

    
    
     1/**
    
     2 * Bootstrap any application services.
    
     3 */
    
     4public function boot(): void
    
     5{
    
     6    Route::resourceVerbs([
    
     7        'create' => 'crear',
    
     8        'edit' => 'editar',
    
     9    ]);
    
    10}
    
    
    /**
     * Bootstrap any application services.
     */
    public function boot(): void
    {
        Route::resourceVerbs([
            'create' => 'crear',
            'edit' => 'editar',
        ]);
    }

Laravel's pluralizer supports [several different languages which you may
configure based on your needs](/docs/12.x/localization#pluralization-
language). 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
    
    2
    
    3/publicacion/{publicaciones}/editar
    
    
    /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:

    
    
    1use App\Http\Controller\PhotoController;
    
    2 
    
    3Route::get('/photos/popular', [PhotoController::class, 'popular']);
    
    4Route::resource('photos', PhotoController::class);
    
    
    use App\Http\Controller\PhotoController;
    
    Route::get('/photos/popular', [PhotoController::class, 'popular']);
    Route::resource('photos', PhotoController::class);

Remember to keep your controllers focused. If you find yourself routinely
needing methods outside of the typical set of resource actions, consider
splitting your controller into two, smaller controllers.

### Singleton Resource Controllers

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:

    
    
    1use App\Http\Controllers\ProfileController;
    
    2use Illuminate\Support\Facades\Route;
    
    3 
    
    4Route::singleton('profile', ProfileController::class);
    
    
    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:

Verb | URI | Action | Route Name  
---|---|---|---  
GET | `/profile` | show | profile.show  
GET | `/profile/edit` | edit | profile.edit  
PUT/PATCH | `/profile` | update | profile.update  
  
Singleton resources may also be nested within a standard resource:

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

Verb | URI | Action | Route Name  
---|---|---|---  
GET | `/photos/{photo}/thumbnail` | show | photos.thumbnail.show  
GET | `/photos/{photo}/thumbnail/edit` | edit | photos.thumbnail.edit  
PUT/PATCH | `/photos/{photo}/thumbnail` | update | photos.thumbnail.update  
  
#### 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:

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

Verb | URI | Action | Route Name  
---|---|---|---  
GET | `/photos/{photo}/thumbnail/create` | create | photos.thumbnail.create  
POST | `/photos/{photo}/thumbnail` | store | photos.thumbnail.store  
GET | `/photos/{photo}/thumbnail` | show | photos.thumbnail.show  
GET | `/photos/{photo}/thumbnail/edit` | edit | photos.thumbnail.edit  
PUT/PATCH | `/photos/{photo}/thumbnail` | update | photos.thumbnail.update  
DELETE | `/photos/{photo}/thumbnail` | destroy | photos.thumbnail.destroy  
  
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:

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

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

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

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

### Middleware and Resource Controllers

Laravel allows you to assign middleware to all, or only specific, methods of
resource routes using the `middleware`, `middlewareFor`, and
`withoutMiddlewareFor` methods. These methods provide fine-grained control
over which middleware is applied to each resource action.

#### Applying Middleware to all Methods

You may use the `middleware` method to assign middleware to all routes
generated by a resource or singleton resource route:

    
    
    1Route::resource('users', UserController::class)
    
    2    ->middleware(['auth', 'verified']);
    
    3 
    
    4Route::singleton('profile', ProfileController::class)
    
    5    ->middleware('auth');
    
    
    Route::resource('users', UserController::class)
        ->middleware(['auth', 'verified']);
    
    Route::singleton('profile', ProfileController::class)
        ->middleware('auth');

#### Applying Middleware to Specific Methods

You may use the `middlewareFor` method to assign middleware to one or more
specific methods of a given resource controller:

    
    
     1Route::resource('users', UserController::class)
    
     2    ->middlewareFor('show', 'auth');
    
     3 
    
     4Route::apiResource('users', UserController::class)
    
     5    ->middlewareFor(['show', 'update'], 'auth');
    
     6 
    
     7Route::resource('users', UserController::class)
    
     8    ->middlewareFor('show', 'auth')
    
     9    ->middlewareFor('update', 'auth');
    
    10 
    
    11Route::apiResource('users', UserController::class)
    
    12    ->middlewareFor(['show', 'update'], ['auth', 'verified']);
    
    
    Route::resource('users', UserController::class)
        ->middlewareFor('show', 'auth');
    
    Route::apiResource('users', UserController::class)
        ->middlewareFor(['show', 'update'], 'auth');
    
    Route::resource('users', UserController::class)
        ->middlewareFor('show', 'auth')
        ->middlewareFor('update', 'auth');
    
    Route::apiResource('users', UserController::class)
        ->middlewareFor(['show', 'update'], ['auth', 'verified']);

The `middlewareFor` method may also be used in conjunction with singleton and
API singleton resource controllers:

    
    
    1Route::singleton('profile', ProfileController::class)
    
    2    ->middlewareFor('show', 'auth');
    
    3 
    
    4Route::apiSingleton('profile', ProfileController::class)
    
    5    ->middlewareFor(['show', 'update'], 'auth');
    
    
    Route::singleton('profile', ProfileController::class)
        ->middlewareFor('show', 'auth');
    
    Route::apiSingleton('profile', ProfileController::class)
        ->middlewareFor(['show', 'update'], 'auth');

#### Excluding Middleware from Specific Methods

You may use the `withoutMiddlewareFor` method to exclude middleware from
specific methods of a resource controller:

    
    
    1Route::middleware(['auth', 'verified', 'subscribed'])->group(function () {
    
    2    Route::resource('users', UserController::class)
    
    3        ->withoutMiddlewareFor('index', ['auth', 'verified'])
    
    4        ->withoutMiddlewareFor(['create', 'store'], 'verified')
    
    5        ->withoutMiddlewareFor('destroy', 'subscribed');
    
    6});
    
    
    Route::middleware(['auth', 'verified', 'subscribed'])->group(function () {
        Route::resource('users', UserController::class)
            ->withoutMiddlewareFor('index', ['auth', 'verified'])
            ->withoutMiddlewareFor(['create', 'store'], 'verified')
            ->withoutMiddlewareFor('destroy', 'subscribed');
    });

## Dependency Injection and Controllers

#### Constructor Injection

The Laravel [service container](/docs/12.x/container) 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
    
     2 
    
     3namespace App\Http\Controllers;
    
     4 
    
     5use App\Repositories\UserRepository;
    
     6 
    
     7class UserController extends Controller
    
     8{
    
     9    /**
    
    10     * Create a new controller instance.
    
    11     */
    
    12    public function __construct(
    
    13        protected UserRepository $users,
    
    14    ) {}
    
    15}
    
    
    <?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:

    
    
     1<?php
    
     2 
    
     3namespace App\Http\Controllers;
    
     4 
    
     5use Illuminate\Http\RedirectResponse;
    
     6use Illuminate\Http\Request;
    
     7 
    
     8class UserController extends Controller
    
     9{
    
    10    /**
    
    11     * Store a new user.
    
    12     */
    
    13    public function store(Request $request): RedirectResponse
    
    14    {
    
    15        $name = $request->name;
    
    16 
    
    17        // Store the user...
    
    18 
    
    19        return redirect('/users');
    
    20    }
    
    21}
    
    
    <?php
    
    namespace App\Http\Controllers;
    
    use Illuminate\Http\RedirectResponse;
    use Illuminate\Http\Request;
    
    class UserController extends Controller
    {
        /**
         * Store a new user.
         */
        public function store(Request $request): RedirectResponse
        {
            $name = $request->name;
    
            // Store the user...
    
            return redirect('/users');
        }
    }

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:

    
    
    1use App\Http\Controllers\UserController;
    
    2 
    
    3Route::put('/user/{id}', [UserController::class, 'update']);
    
    
    use App\Http\Controllers\UserController;
    
    Route::put('/user/{id}', [UserController::class, 'update']);

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

    
    
     1<?php
    
     2 
    
     3namespace App\Http\Controllers;
    
     4 
    
     5use Illuminate\Http\RedirectResponse;
    
     6use Illuminate\Http\Request;
    
     7 
    
     8class UserController extends Controller
    
     9{
    
    10    /**
    
    11     * Update the given user.
    
    12     */
    
    13    public function update(Request $request, string $id): RedirectResponse
    
    14    {
    
    15        // Update the user...
    
    16 
    
    17        return redirect('/users');
    
    18    }
    
    19}
    
    
    <?php
    
    namespace App\Http\Controllers;
    
    use Illuminate\Http\RedirectResponse;
    use Illuminate\Http\Request;
    
    class UserController extends Controller
    {
        /**
         * Update the given user.
         */
        public function update(Request $request, string $id): RedirectResponse
        {
            // Update the user...
    
            return redirect('/users');
        }
    }
