get global parameters in Entity Symfony 2

Question

I'd like to retrieve the Global Parameters from config.yml to entity

    twig:
    ..
        globals:
            image404: image-missing.png

and i want use this param from my static var like:

class Foo extends Bar {

    private static $image404 = "HERE GLOBAL PARAM";

Answer 1

Do

 var_dump($this->container->parameters);

and have a look at the parameter names. There are not always equal to the names in your config.yml. E.g.

$this->container->parameters['twig.globals']['image404'];

may return null. This question was already asked: How do I read configuration settings from Symfony2 config.yml?
