Controller, repo and twig print array (Symfony3) - symfony

Question

I need to print domains of a single user
ENTITY (here is the entity code)
<?php
namespace AppBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
/**
* Domini
*
* #ORM\Table(name="domini")
* #ORM\Entity(repositoryClass="AppBundle\Repository\DominiRepository")
*/
class Domini
{
/**
* #var int
*
* #ORM\Column(name="id", type="integer")
* #ORM\Id
* #ORM\GeneratedValue(strategy="AUTO")
*/
private $id;
/**
* #var int
*
* #ORM\Column(name="id_user", type="integer")
*/
private $idUser;
/**
* #var string
*
* #ORM\Column(name="dominio", type="string", length=100, unique=true)
*/
private $dominio;
/**
* Get id
*
* #return int
*/
public function getId()
{
return $this->id;
}
/**
* Set idUser
*
* #param integer $idUser
*
* #return Domini
*/
public function setIdUser($idUser)
{
$this->idUser = $idUser;
return $this;
}
/**
* Get idUser
*
* #return int
*/
public function getIdUser()
{
return $this->idUser;
}
/**
* Set dominio
*
* #param string $dominio
*
* #return Domini
*/
public function setDominio($dominio)
{
$this->dominio = $dominio;
return $this;
}
/**
* Get dominio
*
* #return string
*/
public function getDominio()
{
return $this->dominio;
}
}
REPOSITORY (here is the Repo code)
<?php
namespace AppBundle\Repository;
use AppBundle\Entity\Domini;
use Doctrine\ORM\EntityRepository;
class DominiRepository extends \Doctrine\ORM\EntityRepository
{
/**
* #return dominio[]
*/
public function findAllPublishedOrderedBySize()
{
$query = 'SELECT dominio FROM AppBundle:Domini dominio';
$mydomain = $this->getEntityManager()->createQuery($query);
return $mydomain->execute();
}
}
CONTROLLER
<?php
// src/AppBundle/Controller/DominiController.php
namespace AppBundle\Controller;
use AppBundle\Entity\Domini;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Method;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Route;
use Symfony\Component\HttpFoundation\Response;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Doctrine\ORM\EntityManagerInterface;
class DominiController extends Controller
{
/**
* #Route("/admin/domini")
*/
public function dominiAction()
{
$title = "ADMIN";
$nome_utente = $this->getUser();
$user = $this->getUser()->getId();
$em = $this->getDoctrine()->getManager();
$dominilist = $em->getRepository('AppBundle:Domini')
->findAllPublishedOrderedBySize();
return $this->render('admin/domini.html.twig', [
'title' => $title,
'nome_utente' => $nome_utente,
'user' => $user,
'dominilist' => $dominilist,
]);
}
}
TWIG
<h1>{{ title }}</h1>
<h2>Benvenuto: {{ nome_utente }}</h2>
<h3>USER ID:{{ user }}</h3>
<ul>
{% for item in dominilist %}
<li>{{ item.dominio }}</li>
{% endfor %}
</ul>
MYSQL TABLE
table name: domini
fields: id, id_user, dominio
Now all works fine but 'dominilist' => $dominilist doesn't work. Dominio is the domain name saved under "dominio". Why?
IF i try to cicle this field it doesn't work.

Answer 1

If you want to select all the data stored in that table, you can use a quick and handy method directly in your controller
# Controller
$dominilist = $em->getRepository('AppBundle:Domini')
->findAll();
Or you can find domini by id in the controller too:
# Controller
$user = $this->getUser()->getId();
$dominilist = $em->getRepository('AppBundle:Domini')->findBy(['id'=>$user]);
And only if you want to have a more complex query, then you can create q method in the repository. As that "I need to print domains of a single user"
# Repository
public function findAllPublishedOrderedBySize($id)
{
$qb = $this->createQueryBuilder('d');
$qb
->select('d.dominio')
->where('d.id = :id')
->setParameter('id', $id)
;
return $qb->getQuery()->getResult();
}
# Controller
$user = $this->getUser()->getId();
$domini = $em->getRepository('AppBundle:Domini')
->findAllPublishedOrderedBySize($user);
Anyway, those type of queries are small, and you can create them in the controller, as I showed you above.
