Class Router

_applyUrlFilters(array $url): array

Applies all the connected URL filters to the URL.

Parameters

Returns

See Also

_loadRoutes(): void

Loads route configuration

Returns

_setContext(Cake\Network\Request $request): void

Store the request context for a given request.

Parameters

Returns

addUrlFilter(callable $function): void

Add a URL filter to Router.

URL filter functions are applied to every array $url provided to Router::url() before the URLs are sent to the route collection.

Callback functions should expect the following parameters:

• $params The URL params being processed.
• $request The current request.

The URL filter function should always return the params even if unmodified.

Usage

URL filters allow you to easily implement features like persistent parameters.

Router::addUrlFilter(function ($params, $request) {
 if (isset($request->params['lang']) && !isset($params['lang'])) {
   $params['lang'] = $request->params['lang'];
 }
 return $params;
});

Parameters

Returns

connect(string $route, array $defaults = [], array $options = []): void

Connects a new Route in the router.

Compatibility proxy to \Cake\Routing\RouteBuilder::connect() in the / scope.

Parameters

Returns

Throws

See Also

defaultRouteClass(string|null $routeClass = null): string|null

Get or set default route class.

Parameters

Returns

extensions(array|string|null $extensions = null, bool $merge = true): array

Get or set valid extensions for all routes connected later.

Instructs the router to parse out file extensions from the URL. For example, http://example.com/posts.rss would yield a file extension of "rss". The file extension itself is made available in the controller as $this->request->params['_ext'], and is used by the RequestHandler component to automatically switch to alternate layouts and templates, and load helpers corresponding to the given content, i.e. RssHelper. Switching layouts and helpers requires that the chosen extension has a defined mime type in Cake\Network\Response.

A string or an array of valid extensions can be passed to this method. If called without any parameters it will return current list of set extensions.

Parameters

Returns

fullBaseUrl(string|null $base = null): string

Sets the full base URL that will be used as a prefix for generating fully qualified URLs for this application. If not parameters are passed, the currently configured value is returned.

Note:

If you change the configuration value App.fullBaseUrl during runtime and expect the router to produce links using the new setting, you are required to call this method passing such value again.

Parameters

Returns

getNamedExpressions(): array

Gets the named route patterns for use in config/routes.php

Returns

See Also

getRequest(bool $current = false): Cake\Network\Request|null

Get the current request object, or the first one.

Parameters

Returns

mapResources(string|array $controller, array $options = []): void

Generate REST resource routes for the given controller(s).

Compatibility proxy to \Cake\Routing\RouteBuilder::resources(). Additional, compatibility around prefixes and plugins and prefixes is handled by this method.

A quick way to generate a default routes to a set of REST resources (controller(s)).

Usage

Connect resource routes for an app controller:

Router::mapResources('Posts');

Connect resource routes for the Comment controller in the Comments plugin:

Router::mapResources('Comments.Comment');

Plugins will create lower_case underscored resource routes. e.g /comments/comment

Connect resource routes for the Posts controller in the Admin prefix:

Router::mapResources('Posts', ['prefix' => 'admin']);

Prefixes will create lower_case underscored resource routes. e.g /admin/posts

Options:

• 'id' - The regular expression fragment to use when matching IDs. By default, matches integer values and UUIDs.
• 'prefix' - Routing prefix to use for the generated routes. Defaults to ''. Using this option will create prefixed routes, similar to using Routing.prefixes.
• 'only' - Only connect the specific list of actions.
• 'actions' - Override the method names used for connecting actions.
• 'map' - Additional resource routes that should be connected. If you define 'only' and 'map', make sure that your mapped methods are also in the 'only' list.

Parameters

Returns

See Also

normalize(array|string $url = '/'): string

Normalizes an URL for purposes of comparison.

Will strip the base path off and replace any double /'s. It will not unify the casing and underscoring of the input value.

Parameters

Returns

parse(string $url): array

Parses given URL string. Returns 'routing' parameters for that URL.

Parameters

Returns

Throws

parseNamedParams(Cake\Network\Request $request, array $options = []): Cake\Network\Request

Provides legacy support for named parameters on incoming URLs.

Checks the passed parameters for elements containing $options['separator'] Those parameters are split and parsed as if they were old style named parameters.

The parsed parameters will be moved from params['pass'] to params['named'].

Options

• separator The string to use as a separator. Defaults to :.

Parameters

Returns

plugin(string $name, array|callable $options = [], callable|null $callback = null): void

Add plugin routes.

This method creates a scoped route collection that includes relevant plugin information.

The plugin name will be inflected to the underscore version to create the routing path. If you want a custom path name, use the path option.

Routes connected in the scoped collection will have the correct path segment prepended, and have a matching plugin routing key set.

Parameters

Returns

popRequest(): Cake\Network\Request

Pops a request off of the request stack. Used when doing requestAction

Returns

See Also

prefix(string $name, array|callable $params = [], callable|null $callback = null): void

Create prefixed routes.

This method creates a scoped route collection that includes relevant prefix information.

The path parameter is used to generate the routing parameter name. For example a path of admin would result in 'prefix' => 'admin' being applied to all connected routes.

You can re-open a prefix as many times as necessary, as well as nest prefixes. Nested prefixes will result in prefix values like admin/api which translates to the Controller\Admin\Api\ namespace.

Parameters

Returns

pushRequest(Cake\Network\Request $request): void

Push a request onto the request stack. Pushing a request sets the request context used when generating URLs.

Parameters

Returns

redirect(string $route, array $url, array $options = []): void

Connects a new redirection Route in the router.

Compatibility proxy to \Cake\Routing\RouteBuilder::redirect() in the / scope.

Parameters

Returns

See Also

reload(): void

Reloads default Router settings. Resets all class variables and removes all connected routes.

Returns

reverse(Cake\Network\Request|array $params, bool $full = false): string

Reverses a parsed parameter array into a string.

Works similarly to Router::url(), but since parsed URL's contain additional 'pass' as well as 'url.url' keys. Those keys need to be specially handled in order to reverse a params array into a string URL.

This will strip out 'autoRender', 'bare', 'requested', and 'return' param names as those are used for CakePHP internals and should not normally be part of an output URL.

Parameters

Returns

routes(): array

Get the route scopes and their connected routes.

Returns

scope(string $path, array|callable $params = [], callable|null $callback = null): void

Create a routing scope.

Routing scopes allow you to keep your routes DRY and avoid repeating common path prefixes, and or parameter sets.

Scoped collections will be indexed by path for faster route parsing. If you re-open or re-use a scope the connected routes will be merged with the existing ones.

Example

Router::scope('/blog', ['plugin' => 'Blog'], function ($routes) {
   $routes->connect('/', ['controller' => 'Articles']);
});

The above would result in a /blog/ route being created, with both the plugin & controller default parameters set.

You can use Router::plugin() and Router::prefix() as shortcuts to creating specific kinds of scopes.

Routing scopes will inherit the globally set extensions configured with Router::extensions(). You can also set valid extensions using $routes->extensions() in your closure.

Parameters

Returns

Throws

setRequestInfo(Cake\Network\Request|array $request): void

Takes parameter and path information back from the Dispatcher, sets these parameters as the current request parameters that are merged with URL arrays created later in the request.

Nested requests will create a stack of requests. You can remove requests using Router::popRequest(). This is done automatically when using Object::requestAction().

Will accept either a Cake\Network\Request object or an array of arrays. Support for accepting arrays may be removed in the future.

Parameters

Returns

url(string|array|null $url = null, bool $full = false): string

Finds URL for specified action.

Returns an URL pointing to a combination of controller and action.

Usage

• Router::url('/posts/edit/1'); Returns the string with the base dir prepended. This usage does not use reverser routing.
• Router::url(['controller' => 'posts', 'action' => 'edit']); Returns a URL generated through reverse routing.
• Router::url(['_name' => 'custom-name', ...]); Returns a URL generated through reverse routing. This form allows you to leverage named routes.

There are a few 'special' parameters that can change the final URL string that is generated

• _base - Set to false to remove the base path from the generated URL. If your application is not in the root directory, this can be used to generate URLs that are 'cake relative'. cake relative URLs are required when using requestAction.
• _scheme - Set to create links on different schemes like webcal or ftp. Defaults to the current scheme.
• _host - Set the host to use for the link. Defaults to the current host.
• _port - Set the port if you need to create links on non-standard ports.
• _full - If true output of Router::fullBaseUrl() will be prepended to generated URLs.
• # - Allows you to set URL hash fragments.
• _ssl - Set to true to convert the generated URL to https, or false to force http.
• _name - Name of route. If you have setup named routes you can use this key to specify it.
