change locale symfony 2.3
提问by Ajouve
I just began with symfony I'm trying to build a multilang website but I have a problem to change the locale
我刚开始使用 symfony 我正在尝试建立一个多语言网站，但我在更改语言环境时遇到了问题
I read some posts and I read the documentation about this but the locale don't change, I try:
我阅读了一些帖子并阅读了有关此的文档，但语言环境没有改变，我尝试：
public function indexAction()
{
$this->get('session')->set('_locale', 'fr');
$request = $this->getRequest();
$locale = $request->getLocale();
return $this->render('PhoneMainBundle:Default:index.html.twig',array('locale'=>$locale));
}
but the value in $locale is always 'en' (my default locale)
但 $locale 中的值始终为“en”（我的默认语言环境）
I also try
我也试试
public function indexAction()
{
$this->get('session')->set('_locale', 'fr');
$request = $this->getRequest();
$request->setLocale('fr');
$locale = $request->getLocale();
return $this->render('PhoneMainBundle:Default:index.html.twig',array('locale'=>$locale));
}
In this case $locale is fr but the translations are always from messages.en.yml
在这种情况下 $locale 是 fr 但翻译总是来自 messages.en.yml
I'd like in a first time to detect the user locale using $_SERVER['HTTP_ACCEPT_LANGUAGE'], maybe using a listner on each page actualisation ?
我想第一次使用 $_SERVER['HTTP_ACCEPT_LANGUAGE'] 检测用户语言环境，也许在每个页面实现上使用一个监听器？
and after I will create a route to change the locale
然后我将创建一条路线来更改语言环境
But I 'd like to find a way to change the locale.
但我想找到一种方法来更改语言环境。
Thanks for your help
谢谢你的帮助

LanguageListener.php:
语言监听器.php：
<?php
namespace Acme\UserBundle\EventListener;
use Symfony\Component\HttpFoundation\Session\Session;
use Symfony\Component\Security\Http\Event\InteractiveLoginEvent;
use Symfony\Component\HttpKernel\Event\GetResponseEvent;
use Symfony\Component\HttpKernel\HttpKernelInterface;
class LanguageListener
{
private $session;
public function setSession(Session $session)
{
$this->session = $session;
}
public function setLocale(GetResponseEvent $event)
{
if (HttpKernelInterface::MASTER_REQUEST !== $event->getRequestType()) {
return;
}
$request = $event->getRequest();
$request->setLocale($request->getPreferredLanguage(array('en', 'de')));
}
}
services.yml:
服务.yml：
acme.language.kernel_request_listener:
class: Acme\UserBundle\EventListener\LanguageListener
tags:
- { name: kernel.event_listener, event: kernel.request, method: setLocale }
About wrong locale detection in twig, there could be a lot of different causes. Search through the SO, you'll definitely find the answer. Make sure that your '_local' var is defined right, make sure that you put your languages files in the right place, etc. FInally, read again the last version of the documentation: http://symfony.com/doc/current/book/translation.html
关于树枝中错误的区域设置检测，可能有很多不同的原因。搜索SO，您一定会找到答案。确保您的“_local”变量定义正确，确保您将语言文件放在正确的位置等。最后，再次阅读文档的最新版本：http://symfony.com/doc/current/书/translation.html

I however added this to make it more dynamic
但是，我添加了它以使其更具动态性

arguments: [ @router, @service_container ]

private $router;
public function __construct($router, $container)
{
// ...
$this->router= $router;
$this->container = $container;
}
public function setSession(Session $session)

$this->session = $session;
}
public function setLocale(GetResponseEvent $event)

if (HttpKernelInterface::MASTER_REQUEST !== $event->getRequestType()) {
return;
}
$request = $event->getRequest();
$request->setLocale($request->getPreferredLanguage($this->container->parameters['jms_i18n_routing.locales']));
}
}
Just to be able to get the parameters and values from config.yml.
只是为了能够从 config.yml 获取参数和值。

If for example your default locale is french, except for one controller you want to have the default locale set to english can do that:
例如，如果您的默认语言环境是法语，除了一个控制器，您希望将默认语言环境设置为英语可以这样做：
routing.yml
路由.yml
desktop_comingsoonpage:
resource: "@RemmelComparabusBundle/Controller/ComingsoonpageController.php"
defaults: { _locale: en }
type: annotation
