How to put pagination on search result using symfony2? - php

Question

I am working on a project using symfony2. I already have my search function and it is already working. But what I want is to have pagination on the search results since there are times that there are a lots of data being retrieve. How can I possibly do it?
Here is my code :
public function searchAction (Request $request) {
$request = $this->getRequest();
$data = $request->get('search');
$em = $this->getDoctrine()->getManager();
$query = $em->createQuery (
'SELECT a,b,c FROM SampleBundle:transactDetail a
JOIN a.transact b
JOIN b.transactType c
WHERE b.pNumber LIKE :data
OR b.senderId LIKE :data'
)
->setParameter('data', "%$data%");
$result = $query->getResult();
if ($result == null ) {
return $this->render('SampleBundle:Sample:noresult.html.twig');
}
return $this->render('SampleBundle:Sample:search.html.twig', array('result' => $result));
}
Thanks in advance.

This is an example of your code with Paginator :
public function searchAction(Request $request, $firstResult = 0, $maxResults = 100)
{
$request = $this->getRequest();
$data = $request->get('search');
$em = $this->getDoctrine()->getManager();
$query = $em->createQuery(
'SELECT a,b,c FROM SampleBundle:transactDetail a
JOIN a.transact b
JOIN b.transactType c
WHERE b.pNumber LIKE :data
OR b.senderId LIKE :data'
)
->setParameter('data', "%$data%")
->setFirstResult($firstResult)
->setMaxResults($maxResults);
$result = new Paginator($query);
if ($result == null) {
return $this->render('SampleBundle:Sample:noresult.html.twig');
}
return $this->render('SampleBundle:Sample:search.html.twig', array('result' => $result));
}
And if you would like to count the total just count($result);.
Paginator has Countable et IteratorAggregate interfaces.
So you can loop on your result without problem.
