How to Configure a Redirect without a custom Controller¶

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 Symfony\Bundle\FrameworkBundle\Controller\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).

Redirecting Using a Path¶

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 urlRedirectAction() action to redirect to this new URL:

YAML

# 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

XML

<!-- 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
        https://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>

PHP

// app/config/routing.php
use Symfony\Component\Routing\Route;
use Symfony\Component\Routing\RouteCollection;

$routes = new RouteCollection();

// load some routes - one should ultimately have the path "/app"
$appRoutes = $loader->import("@AppBundle/Controller/", "annotation");
$appRoutes->setPrefix('/app');

$routes->addCollection($appRoutes);

// redirecting the root
$routes->add('root', new Route('/', [
    '_controller' => 'FrameworkBundle:Redirect:urlRedirect',
    'path'        => '/app',
    'permanent'   => true,
]));

return $routes;

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.

Redirecting Using a Route¶

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 redirectAction() action:

YAML

# app/config/routing.yml

# ...

# redirecting the admin home
root:
    path: /wp-admin
    defaults:
        _controller: FrameworkBundle:Redirect:redirect
        route: sonata_admin_dashboard
        permanent: true

XML

<!-- 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
        https://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>

PHP

// app/config/routing.php
use Symfony\Component\Routing\Route;
use Symfony\Component\Routing\RouteCollection;

$routes = new RouteCollection();
// ...

// redirecting the root
$routes->add('root', new Route('/wp-admin', [
    '_controller' => 'FrameworkBundle:Redirect:redirect',
    'route'       => 'sonata_admin_dashboard',
    'permanent'   => true,
]));

return $routes;

Caution

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.
