Symfony2+Twig, variable in translation return "A message must be a simple text"

Question

When I was doing plain PHP, I was simply doing this:

printf(_("Hello %s !"), $name);

Now with Twig, I must use the trans tag. So I've copy/paste the documentation example, and here's my full template:

{% extends 'MyAppBundle::layout.html.twig' %}

{% block content %}
    <h1>
        {% trans %}
            Hello {{ name }}!
        {% endtrans %}
    </h1>
{% endblock %}

Why Symfony return the following exeption ?

A message must be a simple text in "MyAppBundle::home.html.twig"

One missing bit with the previous answer is the "with" portion that is needed to do the replacement of the variable part of the message.

{% trans with {'%name%':name} %}Hello %name%!{% endtrans %}

This should be the selected answer – Simon Jun 13 '13 at 19:53
According to current docs there's no need to use the `with` part, see http://symfony.com/doc/current/translation.html#twig-templates – hchr Aug 28 '16 at 13:32

The precise syntax for translations is a little different in Symfony2 than it is in standalone Twig. You'll want to check out the Symfony2 documentation for translations in twig templates, found here. The correct syntax would look something like this:

{% trans %}Hello %name%!{% endtrans %}

Hey thanks ! I've also found this syntax: {{ 'welcome.message'|trans({'%titre%':name}) }} – FMaz008 Oct 18 '11 at 17:40

I have a similar issue: to pass my translation path to trans filter, I need to concatenate a string and a variable, then transform into lowercase.

Here {% trans %} and {% endtrans %} are not used, but trans filter instead:

<span>{{ ('statuses.' ~ status | lower) | trans }}</span>

Assuming in the translation there is:

- status:
  - failed: The task has failed

and in the template you pass the variable name with value FAILED.
