Creating a page

<?php namespace Ingewikkeld\TestBundle\Controller; use Symfony\Bundle\FrameworkBundle\Controller\Controller; use Sensio\Bundle\FrameworkExtraBundle\Configuration\Route; use Sensio\Bundle\FrameworkExtraBundle\Configuration\Template; class
DefaultController extends Controller { /** * @Route("/hello/{name}") * @Template() */ public function indexAction($name) { return array('name' => $name); } }

Hello {{ name }}!

http://hostname/app_dev.php/hello/phpday

http://hostname/app_dev.php/hello/phpday hello phpday

class LinkController extends Controller { /** * @Route("/", name="lt_homepage") *
@Template() */ public function indexAction() { $em = $this->get('doctrine')->getEntityManager(); return array( 'recent' => $em->getRepository('IngewikkeldLinkTuesdayBundle:Link')->getMostRecentLinks(), 'top' => $em->getRepository('IngewikkeldLinkTuesdayBundle:Link')->getMostPopularLinks(), 'weektop' => $em->getRepository('IngewikkeldLinkTuesdayBundle:Link') ->getMostPopularLinksSince(date('d-m-Y', time()-(86400*7))), ); }

{% extends '::base.html.twig' %} {% block title %}Linktuesday{% endblock %}
{% block body %} <div class="yui-u first"> <h2>Recent links</h2> <div class="inner"> {% for row in recent %} {% include 'IngewikkeldLinkTuesdayBundle:Link:linkdetail.html.twig' with {'row': row, 'type':'recent'} %} {% endfor %} </div> </div> <div class="yui-u"> <h2>Most popular links</h2> <div class="inner"> {% for row in top %} {% include 'IngewikkeldLinkTuesdayBundle:Link:linkdetail.html.twig' with {'row': row, 'type':'top'} %} {% endfor %} </div> </div> <div class="yui-u"> <h2>Popular this week</h2> <div class="inner"> {% for row in weektop %} {% include 'IngewikkeldLinkTuesdayBundle:Link:linkdetail.html.twig' with {'row': row, 'type':'weektop'} %} {% endfor %} </div> </div> {% endblock %}

adding more pages

/** * @Route("/", name="lt_homepage") * @Template() */ public function indexAction()
{ } /** * @Route("/feed", name="lt_feed") * @Template() */ public function rssAction() { }

getting stuff into the database

the Symfony2 Command system

class FetchTweetCommand extends ContainerAwareCommand { /** * @see Command */
protected function configure() { $this ->setDefinition(array( )) ->setHelp(<<<EOT The <info>linktuesday:fetchtweet</info> command fetches and parses new tweets looking for new links to index <info>./app/console linktuesday:fetchtweet</info> EOT ) ->setName('linktuesday:fetchtweet') ; }

protected function execute(InputInterface $input, OutputInterface $output) { $em = $this->getContainer()->get('doctrine')->getEntityManager();
$search = new Search(); $results = $search->execute('#linktuesday', array('lang' => 'en', 'include_entities' => true )); foreach($results->results as $result) { $link = new Link(); $link->setUri($uri); $tweetDate = new \DateTime($result->created_at); $existingTweet = $em->getRepository('IngewikkeldLinkTuesdayBundle:Tweet')->findOneBy(array( 'date' => $tweetDate->format('Y-m-d G:i:s'), 'user' => $result->from_user, 'content' => $result->text, )); if (!$existingTweet) { $tweet = new Tweet(); $tweet->setContent($result->text); $tweet->setLink($link); $tweet->setDate(new \DateTime($result->created_at)); $tweet->setProfileImage($result->profile_image_url); $tweet->setUser($result->from_user); $tweet->setUri('test'); $tweet->setMessageEntities(Json::encode($result->entities)); $em->persist($tweet); }

$loader = new UniversalClassLoader(); $loader->registerNamespaces(array( // ... 'Ingewikkeld' => __DIR__.'/../src',
'Zend' => __DIR__.'/../vendor/zend', )); use Zend\Json\Json; use Zend\Service\Twitter\Search; $search = new Search(); $results = $search->execute('#linktuesday', array('lang' => 'en', 'include_entities' => true ));
