Parameters inside the defaults collection don’t necessarily have to
match a placeholder in the route path. In fact, you can use the
defaults array to specify extra parameters that will then be accessible as
arguments to your controller:
# app/config/routing.yml
blog:
path: /blog/{page}
defaults:
_controller: AppBundle:Blog:index
page: 1
title: "Hello world!"
<!-- 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">
<route id="blog" path="/blog/{page}">
<default key="_controller">AppBundle:Blog:index</default>
<default key="page">1</default>
<default key="title">Hello world!</default>
</route>
</routes>
// app/config/routing.php
use SymfonyComponentRoutingRouteCollection;
use SymfonyComponentRoutingRoute;
$collection = new RouteCollection();
$collection->add('blog', new Route('/blog/{page}', array(
'_controller' => 'AppBundle:Blog:index',
'page' => 1,
'title' => 'Hello world!',
)));
return $collection;
Now, you can access this extra parameter in your controller:
public function indexAction($page, $title)
{
// ...
}
As you can see, the $title variable was never defined inside the route path,
but you can still access its value from inside your controller.
