php - How to define global variable for Twig

Question

I'm using a file serving as a form layout to overwrite certain elements (form_start, form_row, etc.). I register it like:

twig:
    - AcmeMainBundle:Form:formlayout.html.twig

Is there a way to use in it my variables provided along with a form?

For example, when I send to index.html.twig

array ('form' => $formView, 'var' => $var);

Var is defined only in index.html.twig.

So how to make var defined in formlayout.html.twig

Answer 1

You can use addGlobal() method.

For example in BaseController I use:

$this->get('twig')->addGlobal('is_test', $isTest);

so in your case you should probably do:

$this->get('twig')->addGlobal('var', $var);
