@Ruben says right!

Me I use PoEdit to generate my *.mo files and to be sure to get all translations in the file, I create somewhere (in view for example) a file named _lan.phtml with all text to be translated :

<?php echo $this->translate("My label"); 
... ?>

Of course, Poedit has to be configured to find my keywords. check this to how to configure it

Answer 2

i think your problem is that you label are not detected by poedit (or similar tool), so you have to add them manually to your poedit catalogs (.po)

to make your label strings detected by tools like poedit, your strings need to be used inside a translate() function or _() (other function can be added in Catalog/properties/sources keyword)

as the _() function is not user in ZF2 (today) so a tiny hack is to add a function like this in your index.php (no need to modify anything, this way, in poedit params):

// in index.php
function _($str) 
{ 
    return $str; 
}

and in your code, just use it when your strings are outside of a translate function

//...
    $this->add(array(
        'name' => 'city',
        'type'  => 'Zend\Form\Element\Select',
        'options' => array(
            'label' => _('myLabel') ,    // <------ will be detected by poedit
            'value_options' => $this->cities,
            'id'  => 'searchFormCity',
        ),
    ));
//...

or like this if you prefer

$myLabel = _('any label string');  // <--- added to poedit catalog
//...
        'options' => array(
            'label' => $myLabel ,
            'value_options' => $this->cities,
            'id'  => 'searchFormCity',
        ),

Answer 3

All solutions don't use the power of ZF2. You must configure your poedit correctly :

Instead of using:

<?php echo $form->get('city')->getLabel(); ?>

You should use the formlabel view helper. This helper automatically uses your translator during rendering if you have inserted it in your ServiceManager. Most likely you will have it in your Application's module module.config.php:

'service_manager' => array(
        'factories' => array(
            'translator' => 'Zend\I18n\Translator\TranslatorServiceFactory',
        ),
    ),

    'translator' => array(
        'locale' => 'en_US',
        'translation_file_patterns' => array(
            array(
                'type'     => 'gettext',
                'base_dir' => __DIR__ . '/../language',
                'pattern'  => '%s.mo',
            ),
        ),
    ),

Once you do use the formlabel view helper:

echo $this->formLabel($form->get('city'));

And of course make sure your translations are in your .po file.
