dql select return empty result symfony 3 - php

Question

I'm trying to get all videos from a DB that contain a keyword, It's an API REST building with Symfony 3. Here is a sample of the URL
http://localhost/Server/symfony/web/app_dev.php/video/search/prueba
Where "prueba" is the keyword that i'm trying to find
Here is the function..
public function searchAction(Request $request, $search = null){
$helper = $this->get("app.helper");
$em = $this->getDoctrine()->getManager();
if($search != null){
$dql = "SELECT v.title FROM BackendBundle:Video v "
. "WHERE v.title LIKE :search OR "
. "v.description LIKE :search ORDER BY v.id DESC";
$query = $em->createQuery($dql)
->setParameter("search", "%search%");
} else {
$dql = "SELECT v FROM BackendBundle:Video v ORDER BY v.id DESC";
$query = $em->createQuery($dql);
}
$page = $request->query->getInt("page", 1);
$paginator = $this->get("knp_paginator");
$items_per_page = 6;
$pagination = $paginator->paginate($query, $page, $items_per_page);
$total_items_count = $pagination->getTotalItemCount();
$data = array(
"status" => "success",
"total_items_count" => $total_items_count,
"page_actual" => $page,
"items_per_page" => $items_per_page,
"total_pages" => ceil($total_items_count/$items_per_page),
"data" => $pagination
);
return $helper->toJson($data);
}
The result should be a JSON with 4 videos.. but I get
{
"status": "success",
"total_items_count": 0,
"page_actual": 1,
"items_per_page": 6,
"total_pages": 0,
"data": []
}
where "data" is an array with the video data
Somebody know what I miss? the dql consult.. it's rigth?
Somebody could tell me what is the mistake? I need a clue.. the dql consult is correct?

Answer 1

I see you use knp_paginator service. Try to get items from paginator like this:
$data = array(
"status" => "success",
"total_items_count" => $total_items_count,
"page_actual" => $page,
"items_per_page" => $items_per_page,
"total_pages" => ceil($total_items_count/$items_per_page),
"data" => $pagination->getItems()
);

Thank you for your replay guys!!
So.. I made a mistake while typing.. and I forgot sign $ before the search word..
thats was the probllem
$query = $em->createQuery($dql)
->setParameter("search", "%search%"); <-- here
Thank you so much!!
