Render a field multiple times in Twig and Symfony

I need two inputs so that the user can choose from

Controller

$etud = new Etudiant();
$form=$this->createFormBuilder($etud)
    ->add('filierechoisit',EntityType::class,array('class'=>'inscriptionBundle\Entity\filieres', 'choice_label'=>'libelle_filiere'))
    ->add('filierechoisit',EntityType::class,array('class'=>'inscriptionBundle\Entity\filieres', 'choice_label'=>'libelle_filiere'))->getForm();
if ($form->isValid()) {
    // ... maybe do some form processing, like saving the Task and Tag objects
}

return $this->render('inscriptionBundle:Default:authentification.html.twig', array(
    'modif' => $form->createView(),
));

How can I do it?

You are mixing the form processing and form rendering. If you want user to choose which way he enters data - you do not want to process this data in two different ways until these are two independent fields.

You should just have one 

->add('filierechoisit',EntityType::class,array('class'=>'inscriptionBundle\Entity\filieres', 'choice_label'=>'libelle_filiere'))

call to add field processing and left all rendering for the front-end side. You could use some JS, or API there, or in simple case, just override Twig template for that field

http://symfony.com/doc/current/cookbook/form/form_customization.html

You could render your own widget for your form here, allowing user to do some html stuff to change input.

Currently, making two add with identical names call just makes the second one override the first.

I'm almost sure you want a ChoiceType/EntityType field with multiple and expanded options as true. It should be something like this:

$form->add('filierechoisit', EntityType::class, array(
    # query choices from this entity
    'class' => 'inscriptionBundle\Entity\filieres',
    # use the filieres.libelle_filiere property as the visible option string
    'choice_label' => 'libelle_filiere',
    # used to render a select box, check boxes or radios
    'multiple' => true,
    'expanded' => true,
));
