AdministratorController.php

public function correctionsAction(Request $request) {
    $repository = $this->getDoctrine()->getRepository('AppBundle:Correction');
    $corrections = $repository->findAll();

    foreach ($corrections as $key => $value) {

        $formView[] = $form->createView();
    }
    $form->handleRequest($request);

    if ($form->isSubmitted() && $form->isValid()) {

        $correction = $form->getData();
        $em = $this->getDoctrine()->getManager();
        $em->persist($correction);
        $em->flush();

        return $this->redirectToRoute('admin_view_corrections');
    }

    return $this->render('administrator/corrections.html.twig', array(
                'corrections' => $corrections,
                'form' => $formView
    ));
}

CorrectionType.php

class CorrectionType extends AbstractType {

    public function buildForm(FormBuilderInterface $builder, array $options) {
        $builder
                ->add('adminStatusCorrectionId', EntityType::class, array(
                    'class' => 'AppBundle:AdminStatusCorrection',
                    'choice_label' => 'statusName'
                ))
                ->add('userStatusCorrectionId', EntityType::class, array(
                    'class' => 'AppBundle:UserStatusCorrection',
                    'choice_label' => 'statusName'
                ))
                ->add('areaId', EntityType::class, array(
                    'class' => 'AppBundle:Area',
                    'choice_label' => 'areaName'
                ))
                ->add('save', SubmitType::class, array('label' => 'Aktualizacja'))
        ;
    }

    public function configureOptions(OptionsResolver $resolver) {
        $resolver->setDefaults(array(
            'data_class' => Correction::class,
        ));
    }

}

What can I do now ?

EDIT

All of my form have "correction" name.

In this case i have got 12 forms:

<form name="correction" method="post"></form>

Answer 1

You should have the form handling inside your foreach cycle, also you need to give different name to each of your forms, so you could use the createNamed() method of the 'form.factory':

foreach ($corrections as $key => $value) {
    $formName = 'form_' . $key;
    $form = $this->get('form.factory')->createNamed($formName, CorrectionType::class, $corrections[$key]);

    if ($request->getMethod() === 'POST' && $request->request->has($formName)) {
        $form->handleRequest($request);
    }

    if ($form->isSubmitted() && $form->isValid()) {

        $correction = $form->getData();
        $em = $this->getDoctrine()->getManager();
        $em->persist($correction);
        $em->flush();

        return $this->redirectToRoute('admin_view_corrections');
    }

    $formView[] = $form->createView();
}
