The Laravel router, for use outside of the Laravel framework.
Add the package to your composer.json and run composer update.
{
"require": {
"jenssegers/router": "*"
}
}
To start using the router you will need to bootstrap it like this:
require 'vendor/autoload.php';
use Jenssegers\Routing\Router;
Router::bootstrap();
Once this has been done, you can define any route like you would in Laravel:
Route::get('/', function()
{
echo 'Hello world.';
});
The bootstrap process will check if there is a routes.php file in your application, and will automatically load it for you. It will also register a shutdown function that dispatches the current request. If you want to dispatch the current request manually, you can call Router::dispatch().
The Request, Response, Input and URL facades are also available.
Route::get('/', function()
{
return 'Hello World';
});
Route::post('foo/bar', function()
{
return 'Hello World';
});
Route::match(array('GET', 'POST'), '/', function()
{
return 'Hello World';
});
Route::any('foo', function()
{
return 'Hello World';
});
Route::get('foo', array('https', function()
{
return 'Must be over HTTPS';
}));
Often, you will need to generate URLs to your routes, you may do so using the URL::to method:
$url = URL::to('foo');
Route::get('user/{id}', function($id)
{
return 'User '.$id;
});
Route::get('user/{name?}', function($name = null)
{
return $name;
});
Route::get('user/{name?}', function($name = 'John')
{
return $name;
});
Route::get('user/{name}', function($name)
{
//
})
->where('name', '[A-Za-z]+');
Route::get('user/{id}', function($id)
{
//
})
->where('id', '[0-9]+');
Of course, you may pass an array of constraints when necessary:
Route::get('user/{id}/{name}', function($id, $name)
{
//
})
->where(array('id' => '[0-9]+', 'name' => '[a-z]+'))
If you would like a route parameter to always be constrained by a given regular expression, you may use the pattern method:
Route::pattern('id', '[0-9]+');
Route::get('user/{id}', function($id)
{
// Only called if {id} is numeric.
});
If you need to access a route parameter value outside of a route, you may use the Route::input method:
Route::filter('foo', function()
{
if (Route::input('id') == 1)
{
//
}
});
Route filters provide a convenient way of limiting access to a given route, which is useful for creating areas of your site which require authentication. There are several filters included in the Laravel framework, including an auth filter, an auth.basic filter, a guest filter, and a csrf filter. These are located in the app/filters.php file.
Route::filter('old', function()
{
if (Input::get('age') < 200)
{
return Redirect::to('home');
}
});
If the filter returns a response, that response is considered the response to the request and the route will not execute. Any after filters on the route are also cancelled.
Route::get('user', array('before' => 'old', function()
{
return 'You are over 200 years old!';
}));
Route::get('user', array('before' => 'old', 'uses' => 'UserController@showProfile'));
Route::get('user', array('before' => 'auth|old', function()
{
return 'You are authenticated and over 200 years old!';
}));
Route::get('user', array('before' => array('auth', 'old'), function()
{
return 'You are authenticated and over 200 years old!';
}));
Route::filter('age', function($route, $request, $value)
{
//
});
Route::get('user', array('before' => 'age:200', function()
{
return 'Hello World';
}));
After filters receive a $response as the third argument passed to the filter:
Route::filter('log', function($route, $request, $response)
{
//
});
You may also specify that a filter applies to an entire set of routes based on their URI.
Route::filter('admin', function()
{
//
});
Route::when('admin/*', 'admin');
In the example above, the admin filter would be applied to all routes beginning with admin/. The asterisk is used as a wildcard, and will match any combination of characters.
You may also constrain pattern filters by HTTP verbs:
Route::when('admin/*', 'admin', array('post'));
For advanced filtering, you may wish to use a class instead of a Closure. Since filter classes are resolved out of the application IoC Container, you will be able to utilize dependency injection in these filters for greater testability.
Route::filter('foo', 'FooFilter');
By default, the filter method on the FooFilter class will be called:
class FooFilter {
public function filter()
{
// Filter logic...
}
}
If you do not wish to use the filter method, just specify another method:
Route::filter('foo', 'FooFilter@foo');
Named routes make referring to routes when generating redirects or URLs more convenient. You may specify a name for a route like so:
Route::get('user/profile', array('as' => 'profile', function()
{
//
}));
You may also specify route names for controller actions:
Route::get('user/profile', array('as' => 'profile', 'uses' => 'UserController@showProfile'));
Now, you may use the route's name when generating URLs or redirects:
$url = URL::route('profile');
$redirect = Redirect::route('profile');
You may access the name of a route that is running via the currentRouteName method:
$name = Route::currentRouteName();
Sometimes you may need to apply filters to a group of routes. Instead of specifying the filter on each route, you may use a route group:
Route::group(array('before' => 'auth'), function()
{
Route::get('/', function()
{
// Has Auth Filter
});
Route::get('user/profile', function()
{
// Has Auth Filter
});
});
You may also use the namespace parameter within your group array to specify all controllers within that group as being in a given namespace:
Route::group(array('namespace' => 'Admin'), function()
{
//
});
Laravel routes are also able to handle wildcard sub-domains, and pass you wildcard parameters from the domain:
Route::group(array('domain' => '{account}.myapp.com'), function()
{
Route::get('user/{id}', function($account, $id)
{
//
});
});
A group of routes may be prefixed by using the prefix option in the attributes array of a group:
Route::group(array('prefix' => 'admin'), function()
{
Route::get('user', function()
{
//
});
});
