Using Doctrine Paginator with Zend Framework 2 Paginator
So Doctrine has a Paginator that uses DQL and Zend Framework has a Paginator for paginating whatever the eff. So which do you use, what do you do? Answer: smash them together!
I created a super simple Adapter for Zend\Paginator that uses the Doctrine\ORM\Tools\Pagination\Paginator class:
<?php
namespace Application\Paginator;
use Zend\Paginator\Adapter\AdapterInterface;
use Doctrine\ORM\Tools\Pagination\Paginator;
class DoctrinePaginatorAdapter implements AdapterInterface {
protected $paginator = null;
protected $count = null;
public function __construct(Paginator $paginator) {
$this->paginator = $paginator;
$this->count = count($paginator);
}
public function getItems($offset, $itemCountPerPage) {
return $this->paginator->getIterator();
}
public function count() {
return $this->count;
}
}
Now I have a method in my Repository that gives me a Doctrine\ORM\Tools\Pagination\Paginator:
<?php
public function getPaginator($offset = 0, $limit = 20) {
$dql = 'SELECT e FROM Application\\Domain\\Model\\Entity e ' .
'ORDER BY e.column ASC';
$query = $this->manager->createQuery($dql)
->setMaxResults($limit)
->setFirstResult($offset);
$paginator = new Paginator($query);
return $paginator;
}
Finally, in my controller, I call this method, pass it off to my DoctrinePaginatorAdapter, then hand that off
to Zend\Paginator. Boom!
<?php
public function indexAction() {
$page = $this->params('page');
$max = 20;
$results = $this->repository->getPaginator(($page - 1) * 20, $max);
$adapter = new DoctrinePaginatorAdapter($results);
$paginator = new Paginator($adapter);
$paginator->setCurrentPageNumber($page);
$paginator->setItemCountPerPage($max);
return array(
'paginator' => $paginator
);
}
And just like that, I have pagination marrying Zend Framework and Doctrine’s pagination wizardry. So simple, even a caveman could do it!TM
