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

Answer 1

For Symfony 2.7 and newer

See this answer here.

1st working option

{{ app.request.scheme ~'://' ~ app.request.httpHost ~ asset('bundles/acmedemo/images/search.png') }}

2nd working option - preferred

Just made a quick test with a clean new Symfony copy. There is also another option which combines scheme and httpHost:

{{ app.request.getSchemeAndHttpHost() ~ asset('bundles/acmedemo/images/search.png') }}
{# outputs #}
{# http://localhost/Symfony/web/bundles/acmedemo/css/demo.css  #}

Answer 2

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:

<img src="{{ asset('images/logo.png', absolute=true) }}" alt="Symfony!" />

Answer 3

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:

<a href="{{ absolute_url(path('route_name', {'param' : value})) }}">A link</a>

and for assets:

<img src="{{ absolute_url(asset('bundle/myname/img/image.gif')) }}" alt="Title"/>

Or for any string path

<img src="{{ absolute_url('my/absolute/path') }}" alt="Title"/>

on those tree cases you will end up with an absolute URL like

http://www.example.com/my/absolute/path

Answer 4

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')) }}

Answer 5

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')}}

Answer 6

I've used the following advice from the docs https://symfony.com/doc/current/console/request_context.html to get absolute urls in emails:

# config/services.yaml
parameters:
    router.request_context.host: 'example.org'
    router.request_context.scheme: 'https'
