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

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.

Solution 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() }}

Solution 2:

Why do you need to get this root url ? Can't you generate directly absolute URL's ?

{{ url('_demo_hello', { 'name': 'Thomas' }) }}

This Twig code will generate the full http:// url to the _demo_hello route.

In fact, getting the base url of the website is only getting the full url of the homepage route :

{{ url('homepage') }}

(homepage, or whatever you call it in your routing file).

Solution 3:

You can use the new request method getSchemeAndHttpHost():

{{ app.request.getSchemeAndHttpHost() }}

Solution 4:

Valid from Symfony v2.1 through v4.1+

If you want the base URL to a Symfony application, you should use getSchemeAndHttpHost() concatenated together with getBaseUrl(), similar to how getUri() works, except without the router path and query string.

{{ app.request.schemeAndHttpHost ~ app.request.baseUrl }}

For example, if your Symfony website URL lives at https://www.stackoverflow.com/app1/, then these two methods return these values:

getSchemeAndHttpHost

https://www.stackoverflow.com

getBaseUrl

/app1

Note: getBaseUrl() includes the script filename (ie /app.php) if it's in your URL.

Solution 5:

Base url is defined inside Symfony\Component\Routing\RequestContext.

It can be fetched from controller like this:

$this->container->get('router')->getContext()->getBaseUrl()
