PHP Class lithium\net\http\Router

Using Route objects, these two operations can be handled in a reciprocally consistent way. For example, if you wanted the /login URL to be routed to myapp\controllers\SessionsController::add(), you could set up a route like the following in config/routes.php: {{{ use lithium\net\http\Router; Router::connect('/login', array('controller' => 'Sessions', 'action' => 'add')); -- or -- Router::connect('/login', 'Sessions::add'); }}} Not only would that correctly route all requests for /login to SessionsController::add(), but any time the framework generated a route with matching parameters, Router would return the correct short URL. While most framework components that work with URLs (and utilize routing) handle calling the Router directly (i.e. controllers doing redirects, or helpers generating links), if you have a scenario where you need to call the Router directly, you can use the match() method. This allows you to keep your application's URL structure nicely decoupled from the underlying software design. For more information on parsing and generating URLs, see the parse() and match() methods.

Public Methods

Method Description
attach ( $name, $config = null, array $vars = [] ) Attach a scope to a mount point.
attached ( $name = null, array $vars = [] ) : mixed Returns an attached mount point configuration.
config ( array $config = [] ) : array Modify Router configuration settings and dependencies.
connect ( string | object $template, array | string $params = [], array | callable $options = [] ) : array Connects a new route and returns the current routes array. This method creates a new Route object and registers it with the Router. The order in which routes are connected matters, since the order of precedence is taken into account in parsing and matching operations.
formatters ( array $formatters = [] ) : array Used to get or set an array of named formatter closures, which are used to format route parameters when generating URLs. For example, for controller/action parameters to be dashed instead of underscored or camelBacked, you could do the following:
get ( integer $route = null, string | boolean $scope = null ) : object | array | null Returns one or multiple connected routes.
match ( array | string $url = [], Request $context = null, array $options = [] ) : string Attempts to match an array of route parameters (i.e. 'controller', 'action', etc.) against a connected Route object. For example, given the following route:
modifiers ( array $modifiers = [] ) : array Used to get or set an array of named formatter closures, which are used to format route parameters when parsing URLs. For example, the following would match a posts/index url to a PostsController::indexAction() method.
parse ( object $request ) : array Accepts an instance of lithium\action\Request (or a subclass) and matches it against each route, in the order that the routes are connected.
process ( Request $request ) : Request Wrapper method which takes a Request object, parses it through all attached Route objects, assigns the resulting parameters to the Request object, and returns it.
reset ( ) Resets the Router to its default state, unloading all routes.
scope ( string $name = null, Closure $closure = null ) : mixed Scope getter/setter.

formatters() public static method

use lithium\util\Inflector; Router::formatters(array( 'controller' => function($value) { return Inflector::slug($value); }, 'action' => function($value) { return Inflector::slug($value); } )); _Note_: Because formatters are copied to Route objects on an individual basis, make sure you append custom formatters _before_ connecting new routes.
public static formatters ( array $formatters = [] ) : array
$formatters array An array of named formatter closures to append to (or overwrite) the existing list.
return array Returns the formatters array.

get() public static method

A specific route can be retrived by providing its index. All connected routes inside all scopes may be retrieved by providing null instead of the route index. To retrieve all routes for the current scope only, pass true for the $scope parameter.
public static get ( integer $route = null, string | boolean $scope = null ) : object | array | null
$route integer Index of the route.
$scope string | boolean Name of the scope to get routes from. Uses default scope if `true`.
return object | array | null If $route is an integer, returns the route object at given index or if that fails returns `null`. If $route is `null` returns an array of routes or scopes with their respective routes depending on the value of $scope.

match() public static method

Router::connect('/login', array('controller' => 'users', 'action' => 'login')); This will match: $url = Router::match(array('controller' => 'users', 'action' => 'login')); returns /login For URLs templates with no insert parameters (i.e. elements like {:id} that are replaced with a value), all parameters must match exactly as they appear in the route parameters. Alternatively to using a full array, you can specify routes using a more compact syntax. The above example can be written as: $url = Router::match('Users::login'); // still returns /login You can combine this with more complicated routes; for example: Router::connect('/posts/{:id:\d+}', array('controller' => 'posts', 'action' => 'view')); This will match: $url = Router::match(array('controller' => 'posts', 'action' => 'view', 'id' => '1138')); returns /posts/1138 Again, you can specify the same URL with a more compact syntax, as in the following: $url = Router::match(array('Posts::view', 'id' => '1138')); again, returns /posts/1138 You can use either syntax anywhere an URL is accepted, i.e. when redirecting or creating links using the Html helper.
See also: lithium\action\Controller::redirect()
See also: lithium\template\helper\Html::link()
public static match ( array | string $url = [], Request $context = null, array $options = [] ) : string
$url array | string An array of parameters to match, or paremeters in their shorthand form (i.e. `'Posts::view'`). Also takes non-routed, manually generated URL strings.
$context lithium\action\Request This supplies the context for any persistent parameters, as well as the base URL for the application.
$options array Options for the generation of the matched URL. Currently accepted values are: - `'absolute'` _boolean_: Indicates whether or not the returned URL should be an absolute path (i.e. including scheme and host name). - `'host'` _string_: If `'absolute'` is `true`, sets the host name to be used, or overrides the one provided in `$context`. - `'scheme'` _string_: If `'absolute'` is `true`, sets the URL scheme to be used, or overrides the one provided in `$context`. - `'scope'` _string_: Optionnal scope name.
return string Returns a generated URL, based on the URL template of the matched route, and prefixed with the base URL of the application.

modifiers() public static method

use lithium\util\Inflector; Router::modifiers(array( 'controller' => function($value) { return Inflector::camelize($value); }, 'action' => function($value) { return Inflector::camelize($value) . 'Action'; } )); _Note_: Because modifiers are copied to Route objects on an individual basis, make sure you append your custom modifiers _before_ connecting new routes.
public static modifiers ( array $modifiers = [] ) : array
$modifiers array An array of named formatter closures to append to (or overwrite) the existing list.
return array Returns the formatters array.

parse() public static method

If a route match the request, lithium\net\http\Router::_scope will be updated according the scope membership of the route
See also: lithium\action\Request
See also: lithium\net\http\Router::connect()
public static parse ( object $request ) : array
$request object A request object containing URL and environment data.
return array Returns an array of parameters specifying how the given request should be routed. The keys returned depend on the `Route` object that was matched, but typically include `'controller'` and `'action'` keys.

process() public static method

Wrapper method which takes a Request object, parses it through all attached Route objects, assigns the resulting parameters to the Request object, and returns it.
public static process ( Request $request ) : Request
$request lithium\action\Request
return lithium\action\Request Returns a copy of the request with parameters applied.

reset() public static method

Resets the Router to its default state, unloading all routes.

public static scope ( string $name = null, Closure $closure = null ) : mixed
$name string Name of the scope to use.
$closure Closure A closure to execute inside the scope.
return mixed Returns the previous scope if if `$name` is not null and `$closure` is null, returns the default used scope if `$name` is null, otherwise returns `null`.
