Use ChronoForms Translations in Chronoforms PHP Code

Hi community
​
For a Project i load a "product" from the db. The product itself has different names in different languages.
We are using Joomla Multilanguage and its all up and running (also Translations inside Chronoforms).
Because of the fact that the owner has NOT to handle translations or anything inside Chronoforms Config each product has fields for its title so a product has:
name_de; name_en; name_fr fields. actually i load the name_de field and combine it with a price field in PHP:

$packs = $this->get('read_packages');
$edited = array();

foreach($packs as $pack){
    $edited[$pack[Package][id]] = $pack[Package][name]  . ' CHF ' . $pack[Package][price] . '.-';
}

return $edited;

The $pack[Package][name] is the fieldname that should be variable...
​
Any idea how to build the PHP block with variable fieldnames based on the selected language?
​
kind regards
