Instead of passing variable to template globally  you can define a base template and render the  global part  in it  The base  template can be inherited   Example of rendering template From the symfony Documentation    lt div id  sidebar  gt       render  AcmeArticleBundle Article recentArticles  with   max   3      lt  div gt

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

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

For current Symfony version  as of writing this answer it s Symfony 4 1  do not directly access the service container as done in some of the other answers   Instead  unless you don t use the standard services configuration   inject the request object by type-hinting    lt  php  namespace App Service   use Symfony Component HttpFoundation RequestStack          The YourService class provides a method for retrieving the base URL         package App Service     class YourService                    var string             protected  baseUrl                  YourService constructor                 param  Symfony Component HttpFoundation RequestStack  requestStack             public function   construct RequestStack  requestStack                 this- gt baseUrl    requestStack- gt getCurrentRequest  - gt getSchemeAndHttpHost                          Returns the current base URL                 return string             public function getBaseUrl    string               return  this- gt baseUrl            See also official Symfony docs about how to retrieve the current request object
