Zend Framework 2 Translating the text of the radio buttons - forms

Question

I´m developing an application using Zend Framework 2 and I need to translate the text of the radio buttons ("Show", "Hide") that I´ve created in my form:
//within the Form
public function addRadioButtons ()
{
$isPublicRadioButtons = new Element\Radio('isPublic');
$isPublicRadioButtons->setAttribute('id', 'isPublic')
->setAttribute('value', '0')
->setValueOptions(array(
'0' => 'Show',
'1' => 'Hide',
));
$this->add($isPublicRadioButtons);
}
What do I have to do in the view side to be able to translate them?
I know that to render translations to the views I need to use $this→translate() view helper. So within the view I´ll have to somehow call the text of the radio buttons..
//Whithin the view
echo $this->translate($someHowCallTheTextOfRadioButton('isPublic') , $textDomain, $locale);

Answer 1

Look at FormLabel section to read about translating labels in zend framework 2. I think that most important thing to remember is:
If you have a translator in the Service Manager under the key,
‘translator’, the view helper plugin manager will automatically attach
the translator to the FormLabel view helper. See
Zend\View\HelperPluginManager::injectTranslator() for more
information.

Answer 2

In your view you can do something like this:
$this->formRadio()->setTranslatorTextDomain('textdomainhere');

Answer 3

You can have your form implement the TranslatorAwareInterface and, if you are using PHP 5.4+, have it use the TranslatorAwareTrait (otherwise you simply have to implement the interface yourself). You can now inject a translator instance into your form, e.g. in the form's factory. Then you can translate the labels as follows:
//within the Form
public function addRadioButtons ()
{
$isPublicRadioButtons = new Element\Radio('isPublic');
$isPublicRadioButtons->setAttribute('id', 'isPublic')
->setAttribute('value', '0')
->setValueOptions(array(
'0' => $this->getTranslator()->translate('Show'),
'1' => $this->getTranslator()->translate('Hide'),
));
$this->add($isPublicRadioButtons);
}
