Public Methods

Method	Description
connect ( string $route, array $defaults = [], array $options = [] ) : array	Connects a new Route in the router.
connectNamed ( array $named, array $options = [] ) : array	Specifies what named parameters CakePHP should be parsing out of incoming URLs. By default CakePHP will parse every named parameter out of incoming URLs. However, if you want to take more control over how named parameters are parsed you can use one of the following setups:
currentRoute ( ) : CakeRoute	Returns the route matching the current request (useful for requestAction traces)
defaultRouteClass ( string $routeClass = null ) : string \| null	Set the default route class to use or return the current one
extensions ( ) : array	Get the list of extensions that can be parsed by Router.
fullBaseUrl ( string $base = null ) : string	Sets the full base URL that will be used as a prefix for generating fully qualified URLs for this application. If no parameters are passed, the currently configured value is returned.
getNamedExpressions ( ) : array	Gets the named route elements for use in app/Config/routes.php
getParam ( string $name = 'controller', boolean $current = false ) : string \| null	Gets URL parameter by name
getParams ( boolean $current = false ) : array	Gets parameter information
getPaths ( boolean $current = false ) : array	Gets path information
getRequest ( boolean $current = false ) : CakeRequest \| null	Gets the current request object, or the first one.
mapResources ( string \| array $controller, array $options = [] ) : array	Creates REST resource routes for the given controller(s). When creating resource routes for a plugin, by default the prefix will be changed to the lower_underscore version of the plugin name. By providing a prefix you can override this behavior.
namedConfig ( ) : array	Gets the current named parameter configuration values.
normalize ( array \| string $url = '/' ) : string	Normalizes a URL for purposes of comparison.
parse ( string $url ) : array	Parses given URL string. Returns 'routing' parameters for that URL.
parseExtensions ( ) : void	Instructs the router to parse out file extensions from the URL.
popRequest ( ) : CakeRequest	Pops a request off of the request stack. Used when doing requestAction
prefixes ( ) : array	Returns the list of prefixes used in connected routes
promote ( integer $which = null ) : boolean	Promote a route (by default, the last one added) to the beginning of the list
queryString ( string \| array $q, array $extra = [], boolean $escape = false ) : array	Generates a well-formed querystring from $q
redirect ( string $route, array $url, array $options = [] ) : array	Connects a new redirection Route in the router.
reload ( ) : void	Reloads default Router settings. Resets all class variables and removes all connected routes.
requestRoute ( ) : CakeRoute	Returns the route matching the current request URL.
resourceMap ( array $resourceMap = null ) : mixed	Resource map getter & setter.
reverse ( CakeRequest \| array $params, boolean $full = false ) : string	Reverses a parsed parameter array into a string.
setExtensions ( array $extensions, boolean $merge = true ) : array	Set/add valid extensions.
setRequestInfo ( CakeRequest \| 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.
stripPlugin ( string $base, string $plugin = null ) : string	Removes the plugin name from the base URL.
url ( string \| array $url = null, boolean \| array $full = false ) : string	Finds URL for specified action.

connect() public static method

Routes are a way of connecting request URLs to objects in your application. At their core routes are a set of regular expressions that are used to match requests to destinations. Examples: Router::connect('/:controller/:action/*'); The first token ':controller' will be used as a controller name while the second is used as the action name. the '/*' syntax makes this route greedy in that it will match requests like /posts/index as well as requests like /posts/edit/1/foo/bar. Router::connect('/home-page', array('controller' => 'pages', 'action' => 'display', 'home')); The above shows the use of route parameter defaults, and providing routing parameters for a static route. Router::connect( '/:lang/:controller/:action/:id', array(), array('id' => '[0-9]+', 'lang' => '[a-z]{3}') ); Shows connecting a route with custom route parameters as well as providing patterns for those parameters. Patterns for routing parameters do not need capturing groups, as one will be added for each route params. $defaults is merged with the results of parsing the request URL to form the final routing destination and its parameters. This destination is expressed as an associative array by Router. See the output of {@link parse()}. $options offers four 'special' keys. pass, named, persist and routeClass have special meaning in the $options array. - pass is used to define which of the routed parameters should be shifted into the pass array. Adding a parameter to pass will remove it from the regular route array. Ex. 'pass' => array('slug') - persist is used to define which route parameters should be automatically included when generating new URLs. You can override persistent parameters by redefining them in a URL or remove them by setting the parameter to false. Ex. 'persist' => array('lang') - routeClass is used to extend and change how individual routes parse requests and handle reverse routing, via a custom routing class. Ex. 'routeClass' => 'SlugRoute' - named is used to configure named parameters at the route level. This key uses the same options as Router::connectNamed() You can also add additional conditions for matching routes to the $defaults array. The following conditions can be used: - [type] Only match requests for specific content types. - [method] Only match requests with specific HTTP verbs. - [server] Only match when $_SERVER['SERVER_NAME'] matches the given value. Example of using the [method] condition: Router::connect('/tasks', array('controller' => 'tasks', 'action' => 'index', '[method]' => 'GET')); The above route will only be matched for GET requests. POST requests will fail to match this route.

connectNamed() public static method

Do not parse any named parameters: Router::connectNamed(false); Parse only default parameters used for CakePHP's pagination: Router::connectNamed(false, array('default' => true)); Parse only the page parameter if its value is a number: Router::connectNamed(array('page' => '[\d]+'), array('default' => false, 'greedy' => false)); Parse only the page parameter no matter what. Router::connectNamed(array('page'), array('default' => false, 'greedy' => false)); Parse only the page parameter if the current action is 'index'. Router::connectNamed( array('page' => array('action' => 'index')), array('default' => false, 'greedy' => false) ); Parse only the page parameter if the current action is 'index' and the controller is 'pages'. Router::connectNamed( array('page' => array('action' => 'index', 'controller' => 'pages')), array('default' => false, 'greedy' => false) ); ### Options - greedy Setting this to true will make Router parse all named params. Setting it to false will parse only the connected named params. - default Set this to true to merge in the default set of named parameters. - reset Set to true to clear existing rules and start fresh. - separator Change the string used to separate the key & value in a named parameter. Defaults to :

public static connectNamed ( array $named, array $options = [] ) : array
$named	array	A list of named parameters. Key value pairs are accepted where values are either regex strings to match, or arrays as seen above.
$options	array	Allows to control all settings: separator, greedy, reset, default
return	array

currentRoute() public static method

Returns the route matching the current request (useful for requestAction traces)

public static currentRoute ( ) : CakeRoute
return	CakeRoute	Matching route object.

defaultRouteClass() public static method

Set the default route class to use or return the current one

public static defaultRouteClass ( string $routeClass = null ) : string \| null
$routeClass	string	The route class to set as default.
return	string \| null	The default route class.

extensions() public static method

To initially set extensions use Router::parseExtensions() To add more see setExtensions()

public static extensions ( ) : array
return	array	Array of extensions Router is configured to parse.

fullBaseUrl() public static method

## 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.

public static fullBaseUrl ( string $base = null ) : string
$base	string	the prefix for URLs generated containing the domain. For example: ``http://example.com``
return	string

getNamedExpressions() public static method

Gets the named route elements for use in app/Config/routes.php

$name	string	Parameter name
$current	boolean	Current parameter, useful when using requestAction
return	string \| null	Parameter value

getParams() public static method

Gets parameter information

public static getParams ( boolean $current = false ) : array
$current	boolean	Get current request parameter, useful when using requestAction
return	array	Parameter information

getPaths() public static method

Gets path information

public static getPaths ( boolean $current = false ) : array
$current	boolean	Current parameter, useful when using requestAction
return	array

getRequest() public static method

Gets the current request object, or the first one.

public static getRequest ( boolean $current = false ) : CakeRequest \| null
$current	boolean	True to get the current request object, or false to get the first one.
return	CakeRequest \| null	Null if stack is empty.

mapResources() public static method

### Options: - 'id' - The regular expression fragment to use when matching IDs. By default, matches integer values and UUIDs. - 'prefix' - URL prefix to use for the generated routes. Defaults to '/'.

public static mapResources ( string \| array $controller, array $options = [] ) : array
$controller	string \| array	A controller name or array of controller names (i.e. "Posts" or "ListItems")
$options	array	Options to use when generating REST routes
return	array	Array of mapped resources

namedConfig() public static method

Gets the current named parameter configuration values.

normalize() public static method

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

public static normalize ( array \| string $url = '/' ) : string
$url	array \| string	URL to normalize Either an array or a string URL.
return	string	Normalized URL

parse() public static method

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

public static parse ( string $url ) : array
$url	string	URL to be parsed
return	array	Parsed elements from URL

parseExtensions() public static method

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->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 CakeResponse A list of valid extension can be passed to this method, i.e. Router::parseExtensions('rss', 'xml'); If no parameters are given, anything after the first . (dot) after the last / in the URL will be parsed, excluding querystring parameters (i.e. ?q=...).

popRequest() public static method

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

prefixes() public static method

Returns the list of prefixes used in connected routes

public static prefixes ( ) : array
return	array	A list of prefixes used in connected routes

promote() public static method

Promote a route (by default, the last one added) to the beginning of the list

public static promote ( integer $which = null ) : boolean
$which	integer	A zero-based array index representing the route to move. For example, if 3 routes have been added, the last route would be 2.
return	boolean	Returns false if no route exists at the position specified by $which.

queryString() public static method

public static queryString ( string \| array $q, array $extra = [], boolean $escape = false ) : array
$q	string \| array	Query string Either a string of already compiled query string arguments or an array of arguments to convert into a query string.
$extra	array	Extra querystring parameters.
$escape	boolean	Whether or not to use escaped &
return	array

redirect() public static method

Redirection routes are different from normal routes as they perform an actual header redirection if a match is found. The redirection can occur within your application or redirect to an outside location. Examples: Router::redirect('/home/*', array('controller' => 'posts', 'action' => 'view'), array('persist' => true)); Redirects /home/* to /posts/view and passes the parameters to /posts/view. Using an array as the redirect destination allows you to use other routes to define where a URL string should be redirected to. Router::redirect('/posts/*', 'http://google.com', array('status' => 302)); Redirects /posts/* to http://google.com with a HTTP status of 302 ### Options: - status Sets the HTTP status (default 301) - persist Passes the params to the redirected route, if it can. This is useful with greedy routes, routes that end in * are greedy. As you can remap URLs and not loose any passed/named args.

reload() public static method

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

public static reload ( ) : void
return	void

requestRoute() public static method

Returns the route matching the current request URL.

public static requestRoute ( ) : CakeRoute
return	CakeRoute	Matching route object.

resourceMap() public static method

Resource map getter & setter.

reverse() public static method

Works similarly to Router::url(), but since parsed URL's contain additional 'pass' and 'named' 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.

public static reverse ( CakeRequest \| array $params, boolean $full = false ) : string
$params	CakeRequest \| array	The params array or CakeRequest object that needs to be reversed.
$full	boolean	Set to true to include the full URL including the protocol when reversing the URL.
return	string	The string that is the reversed result of the array

setExtensions() public static method

To have the extensions parsed you still need to call Router::parseExtensions()

public static setExtensions ( array $extensions, boolean $merge = true ) : array
$extensions	array	List of extensions to be added as valid extension
$merge	boolean	Default true will merge extensions. Set to false to override current extensions
return	array

setRequestInfo() public static method

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 CakeRequest object or an array of arrays. Support for accepting arrays may be removed in the future.

public static setRequestInfo ( CakeRequest \| array $request ) : void
$request	CakeRequest \| array	Parameters and path information or a CakeRequest object.
return	void

stripPlugin() public static method

Removes the plugin name from the base URL.

public static stripPlugin ( string $base, string $plugin = null ) : string
$base	string	Base URL
$plugin	string	Plugin name
return	string	base URL with plugin name removed if present

url() public static method

Returns a URL pointing to a combination of controller and action. Param $url can be: - Empty - the method will find address to actual controller/action. - '/' - the method will find base URL of application. - A combination of controller/action - the method will find URL for it. 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. - ? - Takes an array of query string parameters - # - Allows you to set URL hash fragments. - full_base - If true the Router::fullBaseUrl() value will be prepended to generated URLs.

public static url ( string \| array $url = null, boolean \| array $full = false ) : string
$url	string \| array	Cake-relative URL, like "/products/edit/92" or "/presidents/elect/4" or an array specifying any of the following: 'controller', 'action', and/or 'plugin', in addition to named arguments (keyed array elements), and standard URL arguments (indexed array elements)
$full	boolean \| array	If (bool) true, the full base URL will be prepended to the result. If an array accepts the following keys - escape - used when making URLs embedded in html escapes query string '&' - full - if true the full base URL will be prepended.
return	string	Full translated URL with base path.
