Symfony 2.1 设置语言环境 [英] Symfony 2.1 set locale

问题描述

有人知道如何在 Symfony2.1 中设置语言环境吗?

Does anybody know how to set the locale in Symfony2.1?

我正在尝试:

$this->get('session')->set('_locale', 'en_US');

和

$this->get('request')->setLocale('en_US');

但这些都没有任何效果，开发栏告诉我:

but none of those has any effect, the devbar tells me:

会话属性:无会话属性

无论如何，它始终是使用的后备语言环境，如 config.yml 中所定义

Anyway, it is always the fallback locale that is used, as defined in config.yml

推荐答案

尽管 Symfony 2.1 声明您可以通过 Request 或 Session 对象简单地设置语言环境，但我从未设法让它工作，设置语言环境只是没有效果.

Even though the Symfony 2.1 states that you can simply set the locale via the Request or Session objects, I never managed to have it working, setting the locale simply has no effect.

所以我最终使用了一个监听器和树枝路由来处理区域设置/语言:

So I ended up using a listener coupled with twig routing to handle the locale/language:

听众:

namespace FKMyWebsiteBundleListener;

use SymfonyComponentHttpKernelEventGetResponseEvent;
use SymfonyComponentHttpKernelKernelEvents;
use SymfonyComponentEventDispatcherEventSubscriberInterface;

class LocaleListener implements EventSubscriberInterface
    {
    private $defaultLocale;

    public function __construct($defaultLocale = 'en')
    {
        $this->defaultLocale = $defaultLocale;
    }

    public function onKernelRequest(GetResponseEvent $event)
    {
        $request = $event->getRequest();
        if (!$request->hasPreviousSession()) {
            return;
        }

        if ($locale = $request->attributes->get('_locale')) {
            $request->getSession()->set('_locale', $locale);
        } else {
            $request->setLocale($request->getSession()->get('_locale', $this->defaultLocale));
        }
    }

    static public function getSubscribedEvents()
    {
        return array(
            // must be registered before the default Locale listener
            KernelEvents::REQUEST => array(array('onKernelRequest', 17)),
        );
    }
}

在 service.xml 中注册监听器:

Register the listener in service.xml:

<service id="fk.my.listener" class="FKMyWebsiteBundleListenerLocaleListener">
    <argument>%locale%</argument>
    <tag name="kernel.event_subscriber"/>
</service>

路由必须如下所示:

homepage:
pattern:  /{_locale}
defaults: { _controller: FKMyWebsiteBundle:Default:index, _locale: en }
requirements:
    _locale: en|fr|zh

并处理路由:

{% for locale in ['en', 'fr', 'zh'] %}
    <a href="{{ path(app.request.get('_route'), app.request.get('_route_params')|merge({'_locale' : locale})) }}">
{% endfor %}

这样，当您单击链接更改语言时，将自动设置区域设置.

This way, the locale will automatically be set when you click on a link to change the language.
