// src/Acme/ArticleBundle/Controller/ArticleController.php
class ArticleController extends Controller
{
public function recentArticlesAction($max = 3)
{
// make a database call or other logic to get the "$max" most recent articles
$articles = ...;
return $this->render('AcmeArticleBundle:Article:recentList.html.twig', array('articles' =>
$articles));
}
}
The recentList template is perfectly straightforward:
{# src/Acme/ArticleBundle/Resources/views/Article/recentList.html.twig #}
{% for article in articles %}
{{ article.title }}
{% endfor %}
Notice that we've cheated and hardcoded the article URL in this example
(e.g./article/*slug*). This is a bad practice. In the next section, you'll learn how to do this
correctly.
To include the controller, you'll need to refer to it using the standard string syntax for
controllers (i.e. bundle:controller:action):
{# app/Resources/views/base.html.twig #}
...
{% render "AcmeArticleBundle:Article:recentArticles" with {'max': 3} %}
Whenever you find that you need a variable or a piece of information that you don't have access
to in a template, consider rendering a controller. Controllers are fast to execute and promote
good code organization and reuse.
Linking to Pages
Creating links to other pages in your application is one of the most common jobs for a template.
Instead of hardcoding URLs in templates, use the path Twig function (or the router helper in
PHP) to generate URLs based on the routing configuration. Later, if you want to modify the URL
of a particular page, all you'll need to do is change the routing configuration; the templates will
automatically generate the new URL.
First, link to the "_welcome" page, which is accessible via the following routing configuration:
_welcome:
pattern: /
defaults: { _controller: AcmeDemoBundle:Welcome:index }
