addExtensions() ¶ public
addExtensions(string|array $extensions): void
Add additional extensions to what is already in current scope
Parameters
-
string|array
$extensions One or more extensions to add
Returns
void
connect() ¶ public
connect(string $route, array $defaults = [], array $options = []): void
Connects a new Route.
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:
$routes->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
.
$routes->connect('/home-page', ['controller' => 'Pages', 'action' => 'display', 'home']);
The above shows the use of route parameter defaults. And providing routing parameters for a static route.
$routes->connect(
'/:lang/:controller/:action/:id',
[],
['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 several 'special' keys that 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' => ['slug']
.routeClass
is used to extend and change how individual routes parse requests and handle reverse routing, via a custom routing class. Ex.'routeClass' => 'SlugRoute'
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 tofalse
. Ex.'persist' => ['lang']
_name
is used to define a specific name for routes. This can be used to optimize reverse routing lookups. If undefined a name will be generated for each connected route._ext
is an array of filename extensions that will be parsed out of the url if present. See {@link ScopedRouteCollection::extensions()}._method
Only match requests with specific HTTP verbs.
Example of using the _method
condition:
$routes->connect('/tasks', ['controller' => 'Tasks', 'action' => 'index', '_method' => 'GET']);
The above route will only be matched for GET requests. POST requests will fail to match this route.
Parameters
-
string
$route A string describing the template of the route
-
array
$defaults optional 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.
-
array
$options optional 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.
Returns
void
Throws
InvalidArgumentException
BadMethodCallException
extensions() ¶ public
extensions(null|string|array $extensions = null): array|null
Get or set the extensions in this route builder's scope.
Future routes connected in through this builder will have the connected extensions applied. However, setting extensions does not modify existing routes.
Parameters
-
null|string|array
$extensions optional Either the extensions to use or null.
Returns
array|null
fallbacks() ¶ public
fallbacks(string|null $routeClass = null): void
Connect the /:controller
and /:controller/:action/*
fallback routes.
This is a shortcut method for connecting fallback routes in a given scope.
Parameters
-
string|null
$routeClass optional the route class to use, uses the default routeClass if not specified
Returns
void
namePrefix() ¶ public
namePrefix(string|null $value = null): string
Get/set the name prefix for this scope.
Modifying the name prefix will only change the prefix used for routes connected after the prefix is changed.
Parameters
-
string|null
$value optional Either the value to set or null.
Returns
string
plugin() ¶ public
plugin(string $name, array|callable $options = [], callable|null $callback = null): void
Add plugin routes.
This method creates a new 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
-
string
$name The plugin name to build routes for
-
array|callable
$options optional Either the options to use, or a callback
-
callable|null
$callback optional The callback to invoke that builds the plugin routes Only required when $options is defined.
Returns
void
prefix() ¶ public
prefix(string $name, callable $callback): void
Add 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
-
string
$name The prefix name to use.
-
callable
$callback The callback to invoke that builds the prefixed routes.
Returns
void
redirect() ¶ public
redirect(string $route, array $url, array $options = []): void
Connects a new redirection Route in the router.
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:
$routes->redirect('/home/*', ['controller' => 'posts', 'action' => 'view']);
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 an URL string should be redirected to.
$routes->redirect('/posts/*', 'http://google.com', ['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 args.
Parameters
-
string
$route A string describing the template of the route
-
array
$url An URL to redirect to. Can be a string or a Cake array-based URL
-
array
$options optional 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. As well as supplying patterns for routing parameters.
Returns
void
resources() ¶ public
resources(string $name, array|callable $options = [], callable|null $callback = null): void
Generate REST resource routes for the given controller(s).
A quick way to generate a default routes to a set of REST resources (controller(s)).
Usage
Connect resource routes for an app controller:
$routes->resources('Posts');
Connect resource routes for the Comments controller in the Comments plugin:
Router::plugin('Comments', function ($routes) {
$routes->resources('Comments');
});
Plugins will create lower_case underscored resource routes. e.g
/comments/comments
Connect resource routes for the Articles controller in the Admin prefix:
Router::prefix('admin', function ($routes) {
$routes->resources('Articles');
});
Prefixes will create lower_case underscored resource routes. e.g
/admin/posts
You can create nested resources by passing a callback in:
$routes->resources('Articles', function ($routes) {
$routes->resources('Comments');
});
The above would generate both resource routes for /articles
, and /articles/:article_id/comments
.
You can use the map
option to connect additional resource methods:
$routes->resources('Articles', [
'map' => ['deleteAll' => ['action' => 'deleteAll', 'method' => 'DELETE']]
]);
In addition to the default routes, this would also connect a route for /articles/delete_all
.
By default the path segment will match the key name. You can use the 'path' key inside the resource
definition to customize the path name.
Options:
- 'id' - The regular expression fragment to use when matching IDs. By default, matches integer values and UUIDs.
- 'inflect' - Choose the inflection method used on the resource name. Defaults to 'underscore'.
- '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
-
string
$name A controller name to connect resource routes for.
-
array|callable
$options optional Options to use when generating REST routes, or a callback.
-
callable|null
$callback optional An optional callback to be executed in a nested scope. Nested scopes inherit the existing path and 'id' parameter.
Returns
void
routeClass() ¶ public
routeClass(string|null $routeClass = null): string|null
Get or set default route class.
Parameters
-
string|null
$routeClass optional Class name.
Returns
string|null
scope() ¶ public
scope(string $path, array|callable $params, callable|null $callback = null): void
Create a new routing scope.
Scopes created with this method will inherit the properties of the scope they are added to. This means that both the current path and parameters will be appended to the supplied parameters.
Parameters
-
string
$path The path to create a scope for.
-
array|callable
$params Either the parameters to add to routes, or a callback.
-
callable|null
$callback optional The callback to invoke that builds the plugin routes. Only required when $params is defined.
Returns
void
Throws
InvalidArgumentException
when there is no callable parameter.
