Question

A global variable for a Twig template can be defined inside the config.yml of a Symfony2 application as in the following:

twig:                 
    globals:
      var_name: var_value

Hence, in each Twig template the variable can be used as follows:

{{var_name}}

that will display

var_value

Do you know such a way to get the value of a global variable just inside a Symfony2 controller?

Answer 1

There doesn’t seem to be a way to grab a particular value. But you can get the full array of globals from the twig service and then grab it’s offset.

$twig = $this->container->get('twig');
$globals = $twig->getGlobals();
echo $globals['var_name'];
