Zend_Form Placeholder Translation

Question

I have a Zend application with a Zend_Form, which should use the HTML5 placeholder attribute instead of labels, like done here.

class Application_Form_Usereditprofile extends Zend_Form
{
     public function init()
     {
         [...]
         $this->addElement('text', 'FirstName', array(
            'filters'    => [...],
            'validators' => [...],
            'placeholder'=> 'user_editprofile_firstname', // string I want to translate
         ));
         [...]
     }
}

I initialized Zend_Translate so it should translate my forms by default. This works fine with labels. However, the placeholder gets used as it is, without being translated.

How can I translate the placeholder strings?

Answer 1

You can access the the translate helper like this

'placeholder'=> $this->getView()->translate('user_editprofile_firstname),

btw. the plceholder attribute is not a substitution for the label.

From the spec:

The placeholder attribute should not be used as an alternative to a label.
