Can't update Data in Database

I have a problem with my symfony project.I am creating my portfolio.I created an administration interface to manage my projects.

However, when I want to save multiple photos from my project. None of this updates!

I am sharing some lines from my CS in the hope that you can help me.

public function edit(Project $project, Request $request)    {        $form = $this->createForm(ProjectType::class, $project);        $form->handleRequest($request);        if ($form->isSubmitted() && $form->isValid()) {            $imagesProject = $form->get('imageProjects')->getData();            $imageFirst = $form->get('imageFile')->getData();            if ($imageFirst && $imagesProject) {                foreach ($imagesProject as $imageProject) {                    $fichier = md5(uniqid()) . '.' . $imageProject->guessExtension();                    $imageProject->move(                        $this->getParameter('image_directory'),                        $fichier                    );                }                $imgP = new ImageProject();                $imgP->setFilename($fichier);                $dateP = new \DateTime('now');                $imgP->setUpdatedAt($dateP);                $project->addImageProject($imgP);                $imageFirst = $form->get('imageFile')->getData();                $Imagefile = md5(uniqid()) . '.' . $imageFirst->guessExtension();                try {                    $imageFirst->move(                        $this->getParameter('image_directory'),                        $Imagefile                    );                } catch (FileException $e) {                    dump($e);                }                $project->setFilename($Imagefile);                $datePr = new \DateTime('now');                $project->setUpdatedAt($datePr);                $this->em->flush();                $this->addFlash('add', 'Votre projet a été modifié');                return $this->redirectToRoute('admin.project.index');            } else if ($imageFirst && !$imagesProject) {                $imageFirst = $form->get('imageFile')->getData();                $Imagefile = md5(uniqid()) . '.' . $imageFirst->guessExtension();                $imageFirst->move(                    $this->getParameter('image_directory'),                    $Imagefile                );                $project->setFilename($Imagefile);                $datePr = new \DateTime('now');                $project->setUpdatedAt($datePr);                $this->em->flush();                $this->addFlash('add', 'Votre projet a été modifié');                return $this->redirectToRoute('admin.project.index');            } else if (!$imageFirst && $imagesProject) {                foreach ($imagesProject as $imageProject) {                    $fichier = md5(uniqid()) . '.' . $imageProject->guessExtension();                    $imageProject->move(                        $this->getParameter('image_directory'),                        $fichier                    );                }                $imgP = new ImageProject();                $imgP->setFilename($fichier);                $dateP = new \DateTime('now');                $imgP->setUpdatedAt($dateP);                $project->addImageProject($imgP);                $this->em->flush();                $this->addFlash('add', 'Votre projet a été modifié');                return $this->redirectToRoute('admin.project.index');            } else {                return $this->redirectToRoute('admin.project.index');            }        }        return $this->render('admin/project/edit.html.twig', ['controller_name' => 'AdminPropertyController','project' => $project,'form' => $form->createView()        ]);    }

My Image Entity

    /**     * @ORM\Id()     * @ORM\GeneratedValue()     * @ORM\Column(type="integer")     */    private $id;    /**     * @ORM\Column(type="string", length=255)     */    private $filename;    /**     * @ORM\ManyToOne(targetEntity=Project::class, inversedBy="imageProjects")     */    private $project;    /**     * @ORM\Column(type="datetime")     */    private $updated_at;    /**     * @var File|null     */    private $imageFile;

The goal of my system would be to be able to save several files (pictures) in order to display it on my website.However, I can save one image but when I try to save several, my edit function does not update anything !!
