Create a paginate using KnpPaginator - php

Question

I tried to create a pagination on my website using the bundle KnpPaginator.
In my repository I create a query :
public function getProductsOrderByDateDesc($id_category = null, $max = null){
$qb = $this->createQueryBuilder('p')
->orderBy('p.created_at', 'DESC');
if($max) {
$qb->setMaxResults($max);
}
if($id_category) {
if(is_array($id_category)){
$aIdCategory = implode("','",$id_category);
$qb->andWhere('p.category IN (:ids)')
->setParameter('ids', $aIdCategory);
}else{
$qb->andWhere('p.category = :category_id')
->setParameter('category_id', $id_category);
}
}
$query = $qb->getQuery();
return $query->getArrayResult();
}
In my controller I do :
$repositoryProduct = $em->getRepository('ShopDesktopBundle:Product');
$aProducts = array();
$aProducts = $repositoryProduct->getProductsOrderByDateDesc($id);
$paginator = $this->get('knp_paginator');
$pagination = $paginator->paginate(
$aProducts,
$this->get('request')->query->get('page', 1),
3
);
return $this->render('ShopDesktopBundle:Category:category.html.twig',array(
'aProducts' => $aProducts,
'pagination' => $pagination
));
In view I only show this pagination :
<div class="navigation">
{{ knp_pagination_render(pagination) }}
</div>
The problem is that always displays all products not only the limit who for my example is 3.
For example :
I have 9 products, limit = 3, the pagination is correct "1 2 3" but for every page I see all 9 products
Help me please ! Thx in advance

Almost correct, however you have to use the pagination object instead of the 'aProducts'. In your view, use the following code:
{% for product in pagination %}
<tr {% if loop.index is odd %}class="color"{% endif %}>
<td>{{ product.id }}</td>
<td>{{ product.title }}</td>
</tr>
{% endfor %}
