Question

I would like to use the get method from a User class inherit from FOSUserBundle. but i have an error :

Fatal error: Call to a member function getNom() on a non-object.

My User Class :

<?php
namespace Olr\LoanBundle\Entity;

use FOS\UserBundle\Entity\User as BaseUser;
use Doctrine\ORM\Mapping as ORM;

/**
 * @ORM\Entity
 * @ORM\Table(name="fos_user")

class User extends BaseUser
{
    /**
     * @ORM\Id
     * @ORM\Column(type="integer")
     * @ORM\GeneratedValue(strategy="AUTO")
     */
    protected $id;

    /**
     * @ORM\Column(type="string", length=255)
     *
     */
    protected $nom;

    /**
     * @ORM\Column(type="string", length=255)

    protected $prenom;

    /**

    {
        return $this->id;
    }

    /**

        return $this->adresse;
    }

    /**

     */
    public function getVille()
    {
        return $this->ville;
    }
}

from my controler :

public function invitationAction($token)
{
    $em = $this->getDoctrine()->getEntityManager();
    $entity = $em->getRepository('OlrLoanBundle:User')->findBy(array('salt'=>$token));

    return $this->render('OlrLoanBundle:Tribu:invitation.html.twig',
        array('nom'=>$entity->getNom(),
              'prenom'=>$entity->getPrenom(),
            ));
}

Answer 1

findBy() returns an array, so you cannot invoke methods on it.
