Symfony2.6 - Service - symfony

Question

I have learnt Symfony2 since several months.
I have created a service. When I use it in a simple controller, I have no problem. When I use it in my controller that manages my entity, I have a problem.
My service is:
<?php
namespace Cours\BlogBundle\Services;
class Service1
{
public function creerSlug($texte)
{
$texte = transliterator_transliterate("Latin-ASCII; [:Punctuation:] Remove; Lower();", $texte);
$texte = preg_replace('/[-\s]+/', '-', $texte);
$texte = trim($texte, '-');
return $texte;
}
}
My simple controller is:
<?php
namespace Cours\BlogBundle\Controller;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Symfony\Component\HttpFoundation\Response;
use Symfony\Component\HttpFoundation\Request;
use Cours\BlogBundle\Services\Service1;
class TestController extends Controller
{
public function indexAction()
{
$texte = "Le test du slug";
$service1 = $this->container->get('service1');
$texte = $service1->creerSlug($texte);
return $this->render('CoursBlogBundle:Test:index.html.twig', array('texte' => $texte));
}
}
The action of my controller that manages my entity is:
public function ajouterAction(Request $request)
{
$rubrique = new Rubrique();
$form = $this->createForm(new RubriqueType(), $rubrique);
if ($request->isMethod('POST'))
{
$form->handleRequest($request);
if ($form->isValid())
{
$manager = $this->getDoctrine()->getManager();
$rubrique = $form->getData();
$texte = $rubrique->getTexte();
$service1 = $this->container->get('service1');
$slug = $serviceSlug->creerSlug($texte);
$slug = $rubrique->setSlug($slug);
$manager->persist($rubrique);
$manager->flush();
return $this->redirect($this->generateUrl('cours_blog_accueil'));
}
}
return $this->render('CoursBlogBundle:Rubrique:ajouter.html.twig', array('form' => $form->createView()));
}
My view tells me that my slug can’t be empty.
I think there is a mistake in my action but I can’t find it.
Does anyone help me?
KISSES AND THANK YOU VERY MUCH

Answer 1

change
$service1 = $this->container->get('service1');
$slug = $serviceSlug->creerSlug($texte);
to
$serviceSlug = $this->container->get('service1');
$slug = $serviceSlug->creerSlug($texte);

Answer 2

I suggest to comment/remove $rubrique = $form->getData(); $texte = $rubrique->getTexte(); from ajouterAction and set the text manually (just for testing purpose):
if ($form->isValid())
{
$manager = $this->getDoctrine()->getManager();
// $rubrique = $form->getData();
// $texte = $rubrique->getTexte();
$rubrique->setTexte('Some text');
$service1 = $this->get('service1');
$slug = $service1->creerSlug($rubrique->getTexte());
...
if it works, you can set some validations to the texte field in your form type which prevents entering an invalid value.
Also I suggest to use some libraries (Cocur/Slugify can be a good option) instead of handling the process by yourself.
