Symfony2 array of forms?

Question

Is it possible to create and render and array of forms I know about collections but they don't really fit in my idea?

What I want is something like this

Controller

$data=$em->findAll();
$Forms=$this->createForm(new SomeType,$data);

return $this->render(someView,array("Forms"=>$Forms->createView()));

Twig

  {% for Form in Forms %}
  {{ form(Form)}}
  {% endfor %}

Answer 1

Just create your forms in array:

$data = $em->findAll();
for ($i = 0; $i < $n; $i++) {
    $forms[] = $this->container
        ->get('form.factory')
        ->createNamedBuilder('form_'.$i, new SomeType, $data)
        ->getForm()
        ->createView();
}

return $this->render(someView, array("forms" => $forms));

UPDATED

As mentioned by edlouth you can create each form named separately. I updated my code.

Thx bro, but I got another problem now when I submit one form it send an array of forms the reason is probably cause all submit buttons have same value.How can I solve that ? – Amling

You need to generate different forms. What do you want to achieve? – Incidence

I want to create list of delete forms for every entity so when I click on delete button I want to call some action pass my form ,get data out of it and remove it using doctrine entity manager. – Amling

Create the forms in an array, but give each one a unique name. I've changed it to formbuilder which might not be ideal for you but hopefully something similar will work. I'm also not certain about putting in new SomeType rather than 'form', see http://api.symfony.com/2.4/Symfony/Component/Form/FormFactory.html#method_createNamedBuilder.

$data = $em->findAll();
for ($i = 0; $i < $n; $i++) {

    $forms[] = $this->container
        ->get('form.factory')
        ->createNamedBuilder('form_'.$i, new SomeType, $data)
        ->getForm()
        ->createView();
}

return $this->render(someView, array("forms" => $forms));

You could just edit my answer. It has minor modifications from mine. – Incidence

I agree I could have done. I was not aware I could edit, given my reputation, as I attempted to comment but wasn't permitted to, hence assumed I had to give a separate answer. – Christy

Symfony3:

$datas = $em->findAll();

foreach ($datas as $key=>$data)
{
   $form_name = "form_".$key;
   $form = $this->get('form.factory')->createNamed( 
      $form_name, 
      SomeType::class, 
      $data
   );
   $views[] = $form->createView();
}
return $this->render(someView, ["forms" => $views]);

The action :

$forms = [];

foreach ($articles as $article) {
    $forms[$article->getId()] = $this->get('form.factory')->createNamed(
        'article_'.$article->getId(), // unique form name
        ArticleType::class,
        $article
    );
    $forms[$article->getId()]->handleRequest($request);

    if ($forms[$article->getId()]->isValid()) {
        // do what you want with $forms[$article->getId()]->getData()
        // ...
    }
}

And a better way to render :

return $this->render('some_view.html.twig', [
    'forms' => array_map(function ($form) {
        return $form->createView();
    }, $forms),
]);
