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.
