I've got a problem. When I want to create an article, it shows me this error. And when I want to edit one, it doesn't change anything. It was working before, but then I've added category and comment section. Can you help me ? here is my Controller:

<?php

namespace App\Controller;

use Symfony\Bundle\FrameworkBundle\Controller\AbstractController;
use Symfony\Component\HttpFoundation\Response;
use Symfony\Component\Routing\Annotation\Route;
use App\Entity\Article;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Doctrine\ORM\EntityManagerInterface;
use Doctrine\Persistence\ManagerRegistry;
use Doctrine\Persistence\ObjectManager;
use Symfony\Component\Form\Extension\Core\Type\SubmitType;
use Symfony\Component\Form\Extension\Core\Type\TextType;
use Symfony\Component\Form\Extension\Core\Type\TextareaType;
use Symfony\Component\Form\Extension\HttpFoundation\HttpFoundationExtension;
use Symfony\Component\Form\Forms;
use Symfony\Component\HttpFoundation\Request;
use App\Form\ArticleType;

class BlogController extends AbstractController

{
    
    #[Route('/blog', name: 'blog')]
    public function index(ManagerRegistry $doctrine): Response
    {
        $articles  = $doctrine->getRepository(Article::class)->findAll();

      

        
        return $this->render('blog/index.html.twig', [
        'controller_name' => 'BlogController',
        'articles' => $articles,
    ]);
    }

    

    #[Route("/", name: 'home')]
    public function home() {
        return $this->render('blog/home.html.twig', [
            'title' => "Bienvenue",
            'age' => 31,
        ]);
    }

    #[Route("/blog/new", name: 'blog_create')]
    #[Route("/blog/{id}/edit", name: 'blog_edit')]

    public function form(Article $article = null, Request $request, EntityManagerInterface $manager) {
        
        // si on a pas d'article, donc on est en new
        if(!$article){
            $article = new Article();

        }
      
        

       $form = $this->createForm(ArticleType::class);

        $form->handleRequest($request);
        
        //si on a appuyer sur le bouton et que infos valides, on peut envoyer
        if($form->isSubmitted() && $form->isValid()){
            $manager->persist($article);
            $manager->flush();

            // on redirige vers l'article crée ou modifié
            return $this->redirectToRoute('blog_show', ['id' => $article->getId()]);


        }

        return $this->render('blog/create.html.twig', [
            'formArticle' => $form->createView(),
            // edit Mode a true si il y a un article
            'editMode' => $article->getId() !== null,
        ]);
    }



    #[Route("/blog/{id}", name: 'blog_show')]
    public function show(ManagerRegistry $doctrine , $id){
        $repo = $doctrine->getRepository(Article::class);
        $article = $repo->find($id);
        return $this->render('blog/show.html.twig', [
            'article' => $article,
            
        ]);

    }

    
}

And now, my form:


<?php

namespace App\Form;

use App\Entity\Article;
use App\Entity\Category;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\OptionsResolver\OptionsResolver;
use Symfony\Bridge\Doctrine\Form\Type\EntityType;

class ArticleType extends AbstractType
{
    public function buildForm(FormBuilderInterface $builder, array $options): void
    {
        $builder
            ->add('title')
            ->add('category', EntityType::class, [
                'class' => Category::class,
                'choice_label' => 'title',
            ])
            ->add('content')
            ->add('image')
        ;
    }

    public function configureOptions(OptionsResolver $resolver): void
    {
        $resolver->setDefaults([
            'data_class' => Article::class,
        ]);
    }
}

To end with my Entities:

Thanks in advance guys :))

I won't add the twig file cause it's normal file

CodePudding user response：

I succeeded. In the controllers, I just added:

$this->createForm(ArticleType::class, $article);
