Select all checkboxes in Symfony form view

Question

In symfony form I have some choices, checkboxes.

$form->add('keywords', ChoiceType::class, array(
            'choices' => $keywords,
            'label' => 'With following keywords',
            'expanded' => true,
            'multiple' => true,
        ));

I need all checboxes selected when form is initialised. How I can do that if possible in symfony way or I will need to do that with JavaScript?

Just add choice_attr

$form->add('keywords', ChoiceType::class, array(
            'choices' => $keywords,
            'label' => 'With following keywords',
            'expanded' => true,
            'multiple' => true,
            'choice_attr' => function() {
                return ['checked' => 'checked'];
            },
        ));

Medard, Thanks a lot bro :)

if you're always going to return the same array, you don't need a function for that, just use 'choice_attr' => array('checked => 'checked'); symfony.com/doc/current/reference/forms/types/…

Older comment - specs may have changed since 2016 but to clarify; As of Symfony 3.4 - 6.0 the callback is executed on each of the defined choices options. Causing checked to be applied to all choices regardless of the initial Form data state. For instance when $builder->get('keywords')->getData() = []. While 'choice_attr' => ['checked => 'checked'] executes only on the specified index of the defined choices, for example 'choices' => ['choice_1' => 1] and 'choice_attr' => ['choice_1' => ['checked' => 'checked']].
