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!

Solution 1

Use the attr array, as explained in the documentation:

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

Solution 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.

Solution 3

The solution for problem in Symfony 3.

First:

use Symfony\Component\Form\Extension\Core\Type\TextareaType;

Second: This is the code in Form:

->add('biografia', TextareaType::class, array(
      'label' => 'Como me identifico, Identifiquese utilizando un máximo de 500 caracteres',
      'attr' => array('class' => 'myclass')
      ))

It's better to use rows and columns in my experience, as it matches up to the line height automatically.

Defining rows and cols in twig view is not working on symfony 2.8. It works only during form build as @juan pointed.

I would say this is the best answer because physical dimensions of a form widget should be a matter of particular twig template, and not of the form type class itself.
