How can I set the HTML class attribute to a form <input> using the FormBuilder in Symfony2 ?

Something like this:

->add('birthdate', 'date',array(
      'input' => 'datetime',
      'widget' => 'single_text',
      'attr' => array(
          'class' => 'calendar'
      )
 ))

 {{ form_widget(form.birthdate) }}

I want this inputfield with the attribute class set to calendar

You can do it with FormBuilder. Add this to the array in your FormBuilder:

'attr'=> array('class'=>'span2')

You can to this in Twig or the FormClass as shown in the examples above. But you might want to decide in the controller which class your form should get. Just keep in mind to not have much logic in the controller in general!

    $form = $this->createForm(ContactForm::class, null, [
        'attr' => [
            'class' => 'my_contact_form'
        ]
    ]);
