Symfony 6 form trouble

Question

Currently working on a new web project running under Symfony 6. Unfortunately, I just caught this error :

Variable "ajouterNouveauProjet" does not exist.

By the way, I cannot find the issue ! Here is my controller code :

<?php

namespace App\Controller;

use App\Entity\Projet;
use App\Form\ProjetFormType;
use Doctrine\ORM\EntityManagerInterface;
use phpDocumentor\Reflection\Types\This;
use Symfony\Bundle\FrameworkBundle\Controller\AbstractController;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\HttpFoundation\Response;
use Symfony\Component\Routing\Annotation\Route;

class LandingPageController extends AbstractController
{
    #[Route('/landingPage', name: 'app_landing_page')]
    public function index(): Response
    {
        return $this->render('landing_page/index.html.twig', [
            'controller_name' => 'LandingPageController',
        ]);
    }
    #[Route('/projet', name: 'projet')]
    public function projet(Request $request, EntityManagerInterface $em, ): Response
    {
        //On créé un nouveau produit
        $projet = new Projet();

        $addProjetForm = $this->createForm(ProjetFormType::class, $projet);

        return $this->render('landing_page/projet.html.twig', [
            'ajouterNouveauProjet' => $addProjetForm->createView(),
        ]);

    }
}

and here you can find my view code :

{% extends 'base.html.twig' %}

{% block title %}Projet{% endblock %}

{% block body %}

    {% include "landing_page/_menuDashboard.html.twig" %}


    <form class=" box " method="post">

        <h1 class="title is-1">Mes projets</h1>

Someone got an idea why I have this error ? everything seems to be OK !

Have a great day guys !

I Try to rename my variables and move my folder root.

Answer 1

Try to remove ->createView() in the controller.

If you are using symfony 6.3+ render() is fine. otherwise use renderForm()

In Symfony 6.3 the render() function has changed. The render() method calls $form->createView() to transform the form into a form view instance.

---

Symfony 6.3+

public function projet(Request $request, EntityManagerInterface $em, ): Response
{
    //On créé un nouveau produit
    $projet = new Projet();

    $addProjetForm = $this->createForm(ProjetFormType::class, $projet);

    return $this->render('landing_page/projet.html.twig', [
        'ajouterNouveauProjet' => $addProjetForm,
    ]);

}

symfony <= 6.2

#[Route('/projet', name: 'projet')]
public function projet(Request $request, EntityManagerInterface $em, ): Response
{
     //On créé un nouveau produit
     $projet = new Projet();

     $addProjetForm = $this->createForm(ProjetFormType::class, $projet);

     return $this->renderForm('landing_page/projet.html.twig', [
         'ajouterNouveauProjet' => $addProjetForm,
     ]);

}
