Symfony2+Twig，翻译中的变量返回“A message must be a simple text"； [英] Symfony2+Twig, variable in translation return "A message must be a simple text"

问题描述

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"

500 Internal Server Error - Twig_Error_Syntax

解决方案

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 %}
