Get translated country name from a 2 digit country code in Symfony2/Twig?

Question

I'm using the Symfony2 country Field Type, it works well and country names are translated. I am storing the two-digit country code in the column country of my entity.

How can I display the full, translated country name? This is how I added the field to the form:

$builder     ->add('country', 'country', array(         'label' => 'Paese', 'preferred_choices' => array('IT')     )); 

And then in my controller:

$user = $this->getDoctrine()->getRepository('AcmeHelloBundle:User'); $countryCode = $user->getCountry(); $countryName = null; // Get translated country name from code 

Or in my twig template:

{# Output the country code and name #} {{ user.country }}  {# translated country name from code #}

I'm not sure if you still need... but it might help someone else. this can be done through a twig extension easily (this code is based on @tomaszsobczak's answer )

<?php     // src/Acme/DemoBundle/Twig/CountryExtension.php     namespace Acme\DemoBundle\Twig;       class CountryExtension extends \Twig_Extension {         public function getFilters()         {             return array(                 new \Twig_SimpleFilter('country', array($this, 'countryFilter')),             );         }          public function countryFilter($countryCode,$locale = "en"){             $c = \Symfony\Component\Locale\Locale::getDisplayCountries($locale);              return array_key_exists($countryCode, $c)                 ? $c[$countryCode]                 : $countryCode;         }          public function getName()         {             return 'country_extension';         }     } 

And in your services.yml files

# src/Acme/DemoBundle/Resources/config/services.yml services:     acme.twig.country_extension:         class: Acme\DemoBundle\Twig\CountryExtension         tags:             - { name: twig.extension } 

Usage example inside a twig file:

{{ 'US'|country(app.request.locale) }}
