Umlauts not beeing displayed properly in symfony2

Question

Im having the following problem. If I try to use this code

$form = $this->createFormBuilder()
 ->add('code', 'integer', array(
 'attr' => array('class' => 'login-input')
 ))
 ->add('einlösen', 'submit', array(
 'attr' => array('class' => 'login-submit')
 ))
 ->getForm();

my browser doesnt show the ö in einlösen. If i remove the class attr it works. I thought this might be a css issue but the problem seems to be with symfony, since there is no matter what class I use the ö always gets mangled.

Another thing I realized is that if I do a cache clear the ö is there but as soon as i press the button once and reload the page its not showing up properly again.

• Veve: Can't you add a label to this field? Does your entity property has also an umlaut?

Answer 1

Try to use the label option:

$this->createFormBuilder()
 ->add('submit', 'submit', array(
 'label' => 'einlösen',
 'attr' => array('class' => 'login-submit')
 ))

As an alternative you can set/overwrite the label in twig:

{{ form_widget(form.submit, { 'label': 'einlösen' }) }}

• Veve: As he said in response to my comment, it's a button, it won't help him.
• Rob: hmm the submitType has a label though... but well I generally would recommend switching language of the code to english and move definition of (german) labels to the frontend / translation files.
• Chaos: it seems to work this way. Sorry Veve I misunderstood you there.
