Sometimes, a URL needs to redirect to another URL. You can do that by creating
a new controller action whose only task is to redirect, but using the
RedirectController of
the FrameworkBundle is even easier.
You can redirect to a specific path (e.g. /about) or to a specific route
using its name (e.g. homepage).
Assume there is no default controller for the / path of your application
and you want to redirect these requests to /app. You will need to use the
urlRedirect()
action to redirect to this new url:
# app/config/routing.yml
# load some routes - one should ultimately have the path "/app"
AppBundle:
resource: "@AppBundle/Controller/"
type: annotation
prefix: /app
# redirecting the root
root:
path: /
defaults:
_controller: FrameworkBundle:Redirect:urlRedirect
path: /app
permanent: true
<!-- app/config/routing.xml -->
<?xml version="1.0" encoding="UTF-8" ?>
<routes xmlns="http://symfony.com/schema/routing"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://symfony.com/schema/routing
http://symfony.com/schema/routing/routing-1.0.xsd">
<!-- load some routes - one should ultimately have the path "/app" -->
<import resource="@AppBundle/Controller/"
type="annotation"
prefix="/app"
/>
<!-- redirecting the root -->
<route id="root" path="/">
<default key="_controller">FrameworkBundle:Redirect:urlRedirect</default>
<default key="path">/app</default>
<default key="permanent">true</default>
</route>
</routes>
// app/config/routing.php
use SymfonyComponentRoutingRouteCollection;
use SymfonyComponentRoutingRoute;
$collection = new RouteCollection();
// load some routes - one should ultimately have the path "/app"
$appRoutes = $loader->import("@AppBundle/Controller/", "annotation");
$appRoutes->setPrefix('/app');
$collection->addCollection($appRoutes);
// redirecting the root
$collection->add('root', new Route('/', array(
'_controller' => 'FrameworkBundle:Redirect:urlRedirect',
'path' => '/app',
'permanent' => true,
)));
return $collection;
In this example, you configured a route for the / path and let the
RedirectController redirect it to /app. The permanent switch
tells the action to issue a 301 HTTP status code instead of the default
302 HTTP status code.
Assume you are migrating your website from WordPress to Symfony, you want to
redirect /wp-admin to the route sonata_admin_dashboard. You don’t know
the path, only the route name. This can be achieved using the
redirect()
action:
# app/config/routing.yml
# ...
# redirecting the admin home
root:
path: /wp-admin
defaults:
_controller: FrameworkBundle:Redirect:redirect
route: sonata_admin_dashboard
permanent: true
<!-- app/config/routing.xml -->
<?xml version="1.0" encoding="UTF-8" ?>
<routes xmlns="http://symfony.com/schema/routing"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://symfony.com/schema/routing
http://symfony.com/schema/routing/routing-1.0.xsd">
<!-- ... -->
<!-- redirecting the admin home -->
<route id="root" path="/wp-admin">
<default key="_controller">FrameworkBundle:Redirect:redirect</default>
<default key="route">sonata_admin_dashboard</default>
<default key="permanent">true</default>
</route>
</routes>
// app/config/routing.php
use SymfonyComponentRoutingRouteCollection;
use SymfonyComponentRoutingRoute;
$collection = new RouteCollection();
// ...
// redirecting the root
$collection->add('root', new Route('/wp-admin', array(
'_controller' => 'FrameworkBundle:Redirect:redirect',
'route' => 'sonata_admin_dashboard',
'permanent' => true,
)));
return $collection;
警告
Because you are redirecting to a route instead of a path, the required
option is called route in the redirect action, instead of path
in the urlRedirect action.
