Getting the base url of the website and globally passing it to twig in Symfony 2

Question

I'm making the switch from CodeIgniter to Symfony 2. Can someone please give me an example of how to:

• Get the base url (the url without the route specific parts)
• Globally pass this variable to the twig bundle so I can use it in every template.

Answer 1

This is now available for free in twig templates (tested on sf2 version 2.0.14)

{{ app.request.getBaseURL() }} 

In later Symfony versions (tested on 2.5), try :

{{ app.request.getSchemeAndHttpHost() }}
