In TWIG, is possible to get absolute url of a link with twig variables in it?

Question

I have several URLs that look as follows:

{{domainID}}/action/{{userId}}/anotherAction

And the latter URL points to:

http://localhost/viewA/{{domainID}}/action/{{userId}}/anotherAction

However, If I try to load viewA from viewB through an iframe, the link inside viewA instead of pointing to:

http://localhost/viewA/{{domainID}}/action/{{userId}}/anotherAction

it will point to:

http://localhost/viewB/{{domainID}}/action/{{userId}}/anotherAction

and the user will end up in a 404 page if it follows the latter.

My question is:

Is there anyway to get the absolute path of a url built that way in twig?

EDIT

The route definition is:

@Route("/domain/details/{domainId}", name="domain_detailed_view")

I tried to get the absolute path this way:

{{ url({{domainID}}/action/{{userId}}/anotherAction) }}

but I get this error:

A hash key must be a quoted string, a number, a name, or an expression enclosed in parentheses

Answer 1

The url or path functions take the route name, not the path. You can give it an associative array as an optional second argument if the route requires parameters.

For example:

{{ url('domain_detailed_view', { 'domainId': domainId, 'userId': userId }) }}

I know it's old and answered, but with symfony 3 & twig you can do:

{{ app.request.getSchemeAndHttpHost() }}

/* will match even port :) i.e.
 * http://localhost:8000
 * http://localhost
 * http://example.com
 */

which is extremely helpful :D

You have two ways to do the same thing. Generally you could use url() or path inside absolute_url function like so absoulute_url(path(...)). Consider the following:

// example 1:
{{ url('domain_detailed_view', { 'domainId': domainId, 'userId': userId }) }}
// example 2:
{{ absolute_url(path('domain_detailed_view', { 'domainId': domainId, 'userId': userId })) }}">

// note - those two do the same thing

Generally since Symfony 2.7 you could use absolute_url() with asserts and relative path also (relative to web/root folder). This is how you could use them to set absolute path to image in bundle and in main web folder:

[app/src/UserBundle/Resources/public/img/image.jpg]

<img src="{{ absolute_url(asset('bundle/user/img/image.jpg')) }}" /> // new way since 2.7 up
<img src="{{ asset('bundle/user/img/image.jpg', absolute: true ) }}" /> // old way below 2.7 removed in symfony 3.0

[web/css/img/some.jpg]

<img src="{{ absolute_url('css/img/some.jpg') }}" /> 

This is what symfony recommends to use while rendering email view. http://symfony.com/doc/current/email.html
