    {
        $idc= $categorie->getId();
        return $idc;
    }

     }

Now the action in my controller that would allow me to display events(evenements) after getting the user's id and the category he's interessted in is(the argument $id is the user's id):

 public function interetAction($id)
    {

        $em = $this->getDoctrine()->getEntityManager();

        $users = $em->getRepository('Mql14mqlmeBundle:User')->find($id);
    foreach($users->getCategorie() as $cat) {

    $events=$cat->getEvenement();

}


return $this->container->get('templating')->renderResponse('Mql14mqlmeBundle:Event:interet.html.twig', array(

        'categoriesEvents' => $events,
));

    }   

But with this action even if the user is intressted in many categories, the events that are displayed are of only one categories, so what should I do to be able to dispaly all the events of all the categories that a certain user is intressted in

Answer 1

in your controller at line: $events=$cat->getEvenement(); change it to: $events[]=$cat->getEvenement();

beacause in foreach loop you override $events variable each time.
