Basic Routing
The most basic Laravel routes simply accept a URI and a
Closure, providing a very simple and expressive method of
defining routes:
Route::get('foo', function () {
return 'Hello World';
});The Default Route Files
All Laravel routes are defined in your route files, which are located
in the routes directory. These files are automatically
loaded by the framework. The routes/web.php file defines
routes that are for your web interface. These routes are assigned the
web middleware group, which provides features like session
state and CSRF protection. The routes in routes/api.php are
stateless and are assigned the api middleware group.
For most applications, you will begin by defining routes in your
routes/web.php file.
Available Router Methods
The router allows you to register routes that respond to any HTTP verb:
Route::get($uri, $callback);
Route::post($uri, $callback);
Route::put($uri, $callback);
Route::patch($uri, $callback);
Route::delete($uri, $callback);
Route::options($uri, $callback);Sometimes you may need to register a route that responds to multiple
HTTP verbs. You may do so using the match method. Or, you
may even register a route that responds to all HTTP verbs using the
any method:
Route::match(['get', 'post'], '/', function () {
//
});
Route::any('foo', function () {
//
});CSRF Protection
Any HTML forms pointing to POST, PUT, or
DELETE routes that are defined in the web
routes file should include a CSRF token field. Otherwise, the request
will be rejected. You can read more about CSRF protection in the CSRF documentation:
<form method="POST" action="/profile">
{{ csrf_field() }}
...
</form>Route Parameters
Required Parameters
Of course, sometimes you will need to capture segments of the URI within your route. For example, you may need to capture a user's ID from the URL. You may do so by defining route parameters:
Route::get('user/{id}', function ($id) {
return 'User '.$id;
});You may define as many route parameters as required by your route:
Route::get('posts/{post}/comments/{comment}', function ($postId, $commentId) {
//
});Route parameters are always encased within {} braces and
should consist of alphabetic characters, and may not contain a
- character. Instead of using the - character,
use an underscore (_) instead. Route parameters are
injected into route callbacks / controllers based on their order - the
names of the callback / controller arguments do not matter.
Optional Parameters
Occasionally you may need to specify a route parameter, but make the
presence of that route parameter optional. You may do so by placing a
? mark after the parameter name. Make sure to give the
route's corresponding variable a default value:
Route::get('user/{name?}', function ($name = null) {
return $name;
});
Route::get('user/{name?}', function ($name = 'John') {
return $name;
});Regular Expression Constraints
You may constrain the format of your route parameters using the
where method on a route instance. The where
method accepts the name of the parameter and a regular expression
defining how the parameter should be constrained:
Route::get('user/{name}', function ($name) {
//
})->where('name', '[A-Za-z]+');
Route::get('user/{id}', function ($id) {
//
})->where('id', '[0-9]+');
Route::get('user/{id}/{name}', function ($id, $name) {
//
})->where(['id' => '[0-9]+', 'name' => '[a-z]+']);Global Constraints
If you would like a route parameter to always be constrained by a
given regular expression, you may use the pattern method.
You should define these patterns in the boot method of your
RouteServiceProvider:
/**
* Define your route model bindings, pattern filters, etc.
*
* @return void
*/
public function boot()
{
Route::pattern('id', '[0-9]+');
parent::boot();
}Once the pattern has been defined, it is automatically applied to all routes using that parameter name:
Route::get('user/{id}', function ($id) {
// Only executed if {id} is numeric...
});Named Routes
Named routes allow the convenient generation of URLs or redirects for
specific routes. You may specify a name for a route by chaining the
name method onto the route definition:
Route::get('user/profile', function () {
//
})->name('profile');You may also specify route names for controller actions:
Route::get('user/profile', 'UserController@showProfile')->name('profile');Generating URLs To Named Routes
Once you have assigned a name to a given route, you may use the
route's name when generating URLs or redirects via the global
route function:
// Generating URLs...
$url = route('profile');
// Generating Redirects...
return redirect()->route('profile');If the named route defines parameters, you may pass the parameters as
the second argument to the route function. The given
parameters will automatically be inserted into the URL in their correct
positions:
Route::get('user/{id}/profile', function ($id) {
//
})->name('profile');
$url = route('profile', ['id' => 1]);Route Groups
Route groups allow you to share route attributes, such as middleware
or namespaces, across a large number of routes without needing to define
those attributes on each individual route. Shared attributes are
specified in an array format as the first parameter to the
Route::group method.
Middleware
To assign middleware to all routes within a group, you may use the
middleware method before defining the group. Middleware are
executed in the order they are listed in the array:
Route::middleware(['first', 'second'])->group(function () {
Route::get('/', function () {
// Uses first & second Middleware
});
Route::get('user/profile', function () {
// Uses first & second Middleware
});
});Namespaces
Another common use-case for route groups is assigning the same PHP
namespace to a group of controllers using the namespace
method:
Route::namespace('Admin')->group(function () {
// Controllers Within The "App\Http\Controllers\Admin" Namespace
});Remember, by default, the RouteServiceProvider includes
your route files within a namespace group, allowing you to register
controller routes without specifying the full
App\Http\Controllers namespace prefix. So, you only need to
specify the portion of the namespace that comes after the base
App\Http\Controllers namespace.
Sub-Domain Routing
Route groups may also be used to handle sub-domain routing.
Sub-domains may be assigned route parameters just like route URIs,
allowing you to capture a portion of the sub-domain for usage in your
route or controller. The sub-domain may be specified by calling the the
domain method before defining the group:
Route::domain('{account}.myapp.com')->group(function () {
Route::get('user/{id}', function ($account, $id) {
//
});
});Route Prefixes
The prefix method may be used to prefix each route in
the group with a given URI. For example, you may want to prefix all
route URIs within the group with admin:
Route::prefix('admin')->group(function () {
Route::get('users', function () {
// Matches The "/admin/users" URL
});
});Route Model Binding
When injecting a model ID to a route or controller action, you will
often query to retrieve the model that corresponds to that ID. Laravel
route model binding provides a convenient way to automatically inject
the model instances directly into your routes. For example, instead of
injecting a user's ID, you can inject the entire User model
instance that matches the given ID.
Implicit Binding
Laravel automatically resolves Eloquent models defined in routes or controller actions whose type-hinted variable names match a route segment name. For example:
Route::get('api/users/{user}', function (App\User $user) {
return $user->email;
});Since the $user variable is type-hinted as the
App\User Eloquent model and the variable name matches the
{user} URI segment, Laravel will automatically inject the
model instance that has an ID matching the corresponding value from the
request URI. If a matching model instance is not found in the database,
a 404 HTTP response will automatically be generated.
Customizing The Key Name
If you would like model binding to use a database column other than
id when retrieving a given model class, you may override
the getRouteKeyName method on the Eloquent model:
/**
* Get the route key for the model.
*
* @return string
*/
public function getRouteKeyName()
{
return 'slug';
}Explicit Binding
To register an explicit binding, use the router's model
method to specify the class for a given parameter. You should define
your explicit model bindings in the boot method of the
RouteServiceProvider class:
public function boot()
{
parent::boot();
Route::model('user', App\User::class);
}Next, define a route that contains a {user}
parameter:
Route::get('profile/{user}', function (App\User $user) {
//
});Since we have bound all {user} parameters to the
App\User model, a User instance will be
injected into the route. So, for example, a request to
profile/1 will inject the User instance from
the database which has an ID of 1.
If a matching model instance is not found in the database, a 404 HTTP response will be automatically generated.
Customizing The Resolution Logic
If you wish to use your own resolution logic, you may use the
Route::bind method. The Closure you pass to
the bind method will receive the value of the URI segment
and should return the instance of the class that should be injected into
the route:
public function boot()
{
parent::boot();
Route::bind('user', function ($value) {
return App\User::where('name', $value)->first();
});
}Form Method Spoofing
HTML forms do not support PUT, PATCH or
DELETE actions. So, when defining PUT,
PATCH or DELETE routes that are called from an
HTML form, you will need to add a hidden _method field to
the form. The value sent with the _method field will be
used as the HTTP request method:
<form action="/foo/bar" method="POST">
<input type="hidden" name="_method" value="PUT">
<input type="hidden" name="_token" value="{{ csrf_token() }}">
</form>You may use the method_field helper to generate the
_method input:
{{ method_field('PUT') }}Accessing The Current Route
You may use the current, currentRouteName,
and currentRouteAction methods on the Route
facade to access information about the route handling the incoming
request:
$route = Route::current();
$name = Route::currentRouteName();
$action = Route::currentRouteAction();Refer to the API documentation for both the underlying class of the Route facade and Route instance to review all accessible methods.
