Regex in symfony4

Question

i have a little problem with my regex. Everything seems correct and i checked in Symfony docs, but on my page i dont have the message while the $url is wrong ..

(it just shows me an error page like the field is empty if i enter the wrong $url and if it is the good one, no error)

whould someone have an idea about ? :)

Thank you

<?php

namespace App\Entity;


use Doctrine\ORM\Mapping as ORM;
use Symfony\Component\Validator\Constraints as Assert;

/**
 * @ORM\Table(name="media_video")
 * @ORM\Entity(repositoryClass="App\Repository\MediaVideoRepository")
 * @ORM\HasLifecycleCallbacks // Permet d’utiliser des événements
 */
class MediaVideo
{
    /********** ATTRIBUTS **********/

    /**
     * @ORM\Id()
     * @ORM\GeneratedValue()
     * @ORM\Column(type="integer")
     */
    private $id;

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

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



    /**
     * @ORM\ManyToOne(targetEntity="App\Entity\tricks", inversedBy="mediaVideos")
     * @ORM\JoinColumn(nullable=false)
     */
    private $trick;

    /**
     * @Assert\Regex(
     *     pattern="#^(http|https)://(www.youtube.com|www.dailymotion.com)/#",
     *     match=true,
     *     message="L'url doit correspondre à l'url d'une vidéo Youtube ou DailyMotion"
     * )
     */
    private $url;

This is the error that appears =>

An exception has been thrown during the rendering of a template ("Parameter "id" for route "deleteVideo" must match "[^/]++" ("" given) to generate a corresponding URL.").

Thats the template =>

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

That's the controller =>

     * @param Request $request
     * @return \Symfony\Component\HttpFoundation\RedirectResponse|Response

    {
        // $trick stock toutes les figures récupérées par la variable $trickRepo
        $trick = $this->trickRepo->find($id);

        if (null === $trick) {
            throw new NotFoundHttpException("Cette page n'existe pas");}


        $form = $this->createForm(TricksEditType::class, $trick);
        $form->handleRequest($request);

        /*
        *   isSubmitted() vérifie si le formulaire est soumis
        *  isValide valide les données saisies
        */
        if ($form->isSubmitted() && $form->isValid()) {

            /*
            * (persist) Demande au gestionnaire d'entités(entityManager) de suivre les modifications apportées à l'objet
            * (flush) Pousse les modifications des objets d’entités qu’il suit dans la base de données en une seule transaction
            */
            $this->entityManager->persist($trick);
            $this->entityManager->flush();

            $request->getSession()->getFlashBag()->add('notice', 'Annonce bien modifiée.');

            return $this->redirectToRoute('show', array('id' => $trick->getId()));
        }
        return $this->render('trick/edit.html.twig', array(
            'trick' => $trick,
            'form'   => $form->createView(),
        ));
    }

yes it is like this : Doctrine\DBAL\Exception\NotNullConstraintViolationException: An exception occurred while executing 'INSERT INTO media_video (type, identif, trick_id) VALUES (?, ?, ?)' with params [null, null, 95]: SQLSTATE[23000]: Integrity constraint violation: 1048 Le champ 'type' ne peut être vide (null)

As the error says, The 'type' field can not be empty (null). The error has nothing to do with 'url' field

Like most other validation constraints the Regex constraint will also only be evaluated when the value is not empty (this is to allow a constraint to be optional and being only applied when a value is actually present). In your case your database schema seems to require that a URL is given. To handle this during validation of your object you should also add the NotBlank constraint:

// ...

class MediaVideo
{
    // ...

    /**
     * @Assert\NotBlank()
     * @Assert\Regex(
     *     pattern="#^(http|https)://(www.youtube.com|www.dailymotion.com)/#",
     *     match=true,
     *     message="L'url doit correspondre à l'url d'une vidéo Youtube ou DailyMotion"
     * )
     */
    private $url;

    // ...
}

What is the exact error that you get now? Can you also show how your form handling in the controller looks like?

The error is not related to the url property, but is caused by the path('deleteVideo', {'id': video.id}) part of your template. It seems that the form is used to create new videos. When the form is not valid, this video will tried to be rendered in the template, but since it does not have an id at this stage causes the template rendering to break.
