How to use absolute path in twig functions

Question

I have an application with Symfony2  2 2   When I want to send a mail  I m having trouble with the paths  which are all relative paths and obviously aren t working inside emails  for rendering the paths I m using    lt a href     path  route name     param    value       gt A link lt  a gt    and for assets    lt img src     asset  bundle myname img image gif       alt  Title   gt    The previous examples work fine but the paths are relative therefore I need to append the domain  I can do something like    lt a href  http   domain com   path  route name     param    gt  param1       gt A link lt  a gt    but this is not the best solution for my problem  as I have different domains   Update  I found the solution for paths with the url function but I still need a solution for assets

You probably want to use the assets base urls configuration   framework      templating          assets base urls              http     http   www website com              ssl     https   www website com    http   symfony com doc current reference configuration framework html assets    Note that the configuration is different since Symfony 2 7   framework                assets          base urls              -  http   cdn example com

Symfony 2 7 has a new absolute url which can be used to generate the absolute url  http   symfony com blog new-in-symfony-2-7-the-new-asset-component template-function-changes  It will work on those both cases or a path string    lt a href     absolute url path  route name     param    value        gt A link lt  a gt    and for assets    lt img src     absolute url asset  bundle myname img image gif        alt  Title   gt    Or for any string path   lt img src     absolute url  my absolute path       alt  Title   gt    on those tree cases you will end up with an absolute URL like  http   www example com my absolute path

It s possible to have http   test site com and https   production site com  Then hardcoding the url is a bad idea   I would suggest this     app request scheme           app request host   asset  bundle myname img image gif

Daniel s answer seems to work fine for now  but please note that generating absolute urls using twig s asset function is now deprecated      DEPRECATED - Generating absolute URLs with the Twig asset   function   was deprecated in 2 7 and will be removed in 3 0  Please use   absolute url   instead    Here s the official announcement  http   symfony com blog new-in-symfony-2-7-the-new-asset-component template-function-changes  You have to use the absolute url twig function      Symfony 2 6       asset  logo png   absolute   true         Symfony 2 7       absolute url asset  logo png         It is interesting to note that it also works with path function      absolute url path  index

From Symfony2 documentation  Absolute URLs for assets were introduced in Symfony 2 5   If you need absolute URLs for assets  you can set the third argument  or the absolute argument  to true   Example    lt img src     asset  images logo png   absolute true      alt  Symfony     gt
