Symfony为每个输入字段添加样式

Question

I have a function, in Symfony2, that creates a form. Then I load it using twig and everything works fine.

The problem is that I would like to add style to each label and each input, separately, and I can only add style to the whole form.

private function createEditForm(Client $entity)
{
    $form = $this->createForm(new ClientType(), $entity, array(
        'action' => $this->generateUrl('client_update', array('id' => $entity->getId())),
        'method' => 'PUT',

    ));

    $form->add('submit', 'submit', array('label' => 'Update'));

    return $form;
}

Could I do it the way I'm doing it or do I have to rebuild the function so it doesn't create the form dynamically from an array?

Thank you.

You can customize the class rendered for example in your ClientType via something like this:

$builder->add('name' , 'text' , array( 'attr' => array( 'class' => 'nameInputField' ) ) );

Or you can add/override directly in your twig template as such:

{{ form_row(form.name, { 'attr': { 'class': 'nameInputField' }} ) }}

For advanced cases and re-usability refer to the form customization tutorial here:
