Symfony2 Form Customization

Question

I want something like this:

<textarea rows="30" cols="70"  class="TextBox" style="height:100px;">

but inside my symfony2 aplication and not in the twig template i tried this:

        $builder->add('history', 'textarea', array('label' => 'Nome' , 'max_length' => 1048576 , 'rows' = 30 , 'cols' = 70));

but i get "rows" and "cols" are not options...

in the twig i want something like this:

<label for="history">{{'form_anamnese_history'}}</label>
{{ form_widget(form.history) }}

to be a forum-post-like textbox!

Answer 1

Use the attr array, as explained in the documentation:

$builder->add('history', 'textarea', array(     'attr' => array('cols' => '5', 'rows' => '5'), )); 

Answer 2

You can set the display attributes for textarea in Twig rather than in the form:

{{ form_widget(edit_form.comment, { 'attr': { 
  'style' : 'width:525px', 
  'rows' : '4', 
  'cols' : '30' }} ) }}

As mentioned above, it is better practice to set this in CSS if possible however.
