|
|
*
|
|
* Connecting routes is done using Router::connect(). When parsing incoming requests or reverse matching
|
|
* parameters, routes are enumerated in the order they were connected. You can modify the order of connected
|
|
* routes using Router::promote(). For more information on routes and how to connect them see Router::connect().
|
|
*
|
|
* ### Named parameters
|
|
*
|
|
* Named parameters allow you to embed key:value pairs into path segments. This allows you create hash
|
|
* structures using urls. You can define how named parameters work in your application using Router::connectNamed()

/**
|
|
* Connects a new Route in the router.
|
|
*
|
|
* Routes are a way of connecting request urls to objects in your application. At their core routes
|
|
* are a set or regular expressions that are used to match requests to destinations.
|
|
*
|
|
* Examples:
|
|
*
|
|
* `Router::connect('/:controller/:action/*');`
|
|
*
|
|
* The first parameter 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.
|
|
*
|
|
* $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.
|
|
*
|
|
* @param string $route A string describing the template of the route
|
|
* @param array $defaults An array describing the default route parameters. These parameters will be used by default
|
|
* and can supply routing parameters that are not dynamic. See above.
|
|
* @param array $options An array matching the named elements in the route to regular expressions which that
|
|
* element should match. Also contains additional parameters such as which routed parameters should be
|
|
* shifted into the passed arguments, supplying patterns for routing parameters and supplying the name of a
|
|
* custom routing class.

* @return array Array of routes

|
* @throws RouterException

|

*

|
|
* `Router::redirect('/home/*', array('controller' => 'posts', 'action' => 'view', array('persist' => true)));`
|
|
*
|
|
