locale_name(locale = null)
is a Twig filter to return the locale name given its two-letter code:
{# German #}
{{ 'de'|locale_name }}
By default, the filter uses the current locale. You can pass it explicitly:
{# allemand #}
{{ 'de'|locale_name('fr') }}
{# français (Canada) #}
{{ 'fr_CA'|locale_name('fr_FR') }}
Note: The locale_name filter is part of the IntlExtension which is not installed by default. Install it first:
``` $ composer require twig/intl-extra` ```Then, on Symfony projects, install the twig/extra-bundle:
$ composer require twig/extra-bundle`
Otherwise, add the extension explicitly on the Twig environment:
use Twig\Extra\Intl\IntlExtension;
$twig = new \Twig\Environment(...);
$twig->addExtension(new IntlExtension());
