How to Pass Extra Information from a Route to a Controller
5+
==========================================================
6+
7+
Parameters inside the ``defaults`` collection don't necessarily have to
8+
match a placeholder in the route ``path``. In fact, you can use the
9+
``defaults`` array to specify extra parameters that will then be accessible as
10+
arguments to your controller:
11+
12+
..configuration-block::
13+
14+
..code-block::yaml
15+
16+
# app/config/routing.yml
17+
blog:
18+
path:/blog/{page}
19+
defaults:
20+
_controller:AcmeBlogBundle:Blog:index
21+
page:1
22+
title:"Hello world!"
23+
24+
..code-block::xml
25+
26+
<!-- app/config/routing.xml-->
27+
<?xml version="1.0" encoding="UTF-8" ?>
28+
<routesxmlns="http://symfony.com/schema/routing"
29+
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
30+
xsi:schemaLocation="http://symfony.com/schema/routing
31+
http://symfony.com/schema/routing/routing-1.0.xsd">
32+
33+
<routeid="blog"path="/blog/{page}">
34+
<defaultkey="_controller">AcmeBlogBundle:Blog:index</default>
35+
<defaultkey="page">1</default>
36+
<defaultkey="title">Hello world!</default>
37+
</route>
38+
</routes>
39+
40+
..code-block::php
41+
42+
// app/config/routing.php
43+
use Symfony\Component\Routing\RouteCollection;
44+
use Symfony\Component\Routing\Route;
45+
46+
$collection = new RouteCollection();
47+
$collection->add('blog', new Route('/blog/{page}', array(
48+
'_controller' => 'AcmeBlogBundle:Blog:index',
49+
'page' => 1,
50+
'title' => 'Hello world!',
51+
)));
52+
53+
return $collection;
54+
55+
Now, you can access this extra parameter in your controller::
56+
57+
public function indexAction($page, $title)
58+
{
59+
// ...
60+
}
61+
62+
As you can see, the ``$title`` variable was never defined inside the route path,
63+
but you can still access its value from inside your controller.
