How to add placeholder on an input in Symfony 4 form?

In a Symfony 4 form, I am trying to get a placeholder on my input. I tried the code below, but I get an error telling me it's not allowed. Any ideas how else I can achieve this?

$builder->add(
    'firstname', 
    TextType::class, 
    ['label' => 'Vorname ', 'placeholder' => 'Your name',]
)

As suggested in the documentation I have also tried the code below, in this case I am not getting an error, but nothing is rendered.

$builder->add(
    'firstname', 
    TextType::class, 
    ['label' => 'Vorname '], 
    ['attr' => ['placeholder' => 'Vorname ']]
)
Solution

  • You need to do like this :

    ->add('firstname', TextType::class, array(
      'label' => 'Vorname ',
      'attr' => array(
          'placeholder' => 'hereYourPlaceHolder'
      )
 ))

    As they say in the documentation
