Symfony: How to disable form fields autocomplete?

Question

I used this in twig :

{{ form_start(form, { 'attr': {'autocomplete': 'off'} })  }}

and this in the controller action :

'attr'=>array('autocomplete' => 'off'

But the autocomplete still not disabled!!!!

Answer 1

UPDATE: If you are using symfony 4 the proper way is using off

'attr'=>['autocomplete' => 'off']

Answer 2

You can use :'attr' => ['autocomplete' => 'disabled']
