How to Make Form_Rest() Not Display a Field with Symfony2

How to make form_rest() not display a field with Symfony2?

Another option is to explicitly mark the field as rendered:

{% do form.contenu.setRendered %}

How to render form_rest() as hidden fields in Symfony2/Twig?

You have to do it in you buildForm function, inside the "FormController". Just adding 'hidden' when you add the field is enough.

public function buildForm(FormBuilder $builder, array $options)
{
    $builder->add('name');
    $builder->add('email', 'email');
    $builder->add('subject');
    $builder->add('anyone', 'hidden');
}

form_rest command showing previously-rendered Collection field

This seems like a bug in the form rendering. I managed to disable the extra form rendering in the form_rest function, by adding this code just after rendering the collection elements:

{% do form.uploads.setRendered() %}

Where "uploads" is my collection field type.
This doesn't seem like best practice to me though.

So the whole rendering looks like this:

 <div id="uploads" data-prototype="{{ form_widget(form.uploads.vars.prototype)|e }}">
        {% for upload in form.uploads %}
            {{ form_widget(upload) }}
        {% endfor %}
  </div>
  {% do form.uploads.setRendered() %}

Form in Symfony is fully displayed, instead of just some parts?

form_end() also outputs form_rest(), which renders all fields that have not yet been rendered for the given form: http://symfony.com/doc/current/reference/forms/twig_reference.html#form-rest-view-variables

If you don't want to render the unrendered fields, add {'render_rest': false} to form_end:

 {{ form_end(form, {'render_rest': false}) }}

Render form without value in Symfony2

You could modify your entity in order to do this:

class MyEntity{

    const DEFAULT_FOO = "Default value";
    // ...

    private $foo;

    // ...

    public function setFoo($foo){
        if ( $foo === null ){
            $foo = self::DEFAULT_FOO;
        }

        $this->foo = $foo;
    }

    // ...
}

And then make sure that you set by_reference in order to ensure setter is being invoked each time:

$builder->add('field', 'text', array(
    'by_reference' => true
));    

How do you hide labels in a form class in symfony2?

Since Symfony 2.2 you can avoid the <label> rendering using the false value for the label attribute:

public function buildForm(FormBuilderInterface $builder, array $options)
{
    $builder
        ->add('Name', null, array('label' => false))
    ;
}
