我需要创建一个类似facebook lang系统的系统，当用户点击语言以示例france（'fr'）页面将重新加载并且将显示messages.fr.yml中的所有内容...
我尝试制作像/language/{localExtension}这样的路线，但当我在那里设置Locale然后重定向它就不起作用了......我不知道我假设它只是某个页面不是全局的？因为当我在控制器的顶部设置setLocale('fr')时，它可以工作......
我在使用www.example.com/contact/en，/contact/fr等
但我希望/contact和以前选择的语言显示的内容。或者默认情况下'en'就像现在用户没有改变它...
我整天都在谷歌搜索，我认为应该用...来完成... service =＆gt;在kernel.request上监听器和...？或类似的东西。
以下是有趣的链接Symfony2 wrong locale detection?我认为这就是我所需要的？要么？我试图设置服务并创建监听器，但是出现了一些错误，我甚至不知道这是否是创建它的方式：/

是的，出于某种原因你需要使用一个监听器：
<?php
namespace Your\Bundle\Listener;
use Symfony\Component\HttpKernel\Event\GetResponseEvent;
use Symfony\Component\HttpKernel\KernelEvents;
use Symfony\Component\EventDispatcher\EventSubscriberInterface;
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中注册您的监听器：
<service id="my.listener" class="Your\Bundle\Listener\LocaleListener">
<argument>%locale%</argument>
<tag name="kernel.event_subscriber"/>
</service>
如何在twig模板中实现语言切换器的示例：
{% for locale in ['en', 'fr','zh'] %}
<li>
<a href="{{ path(app.request.get('_route'), app.request.get('_route_params')|merge({'_locale' : locale})) }}">
{% if locale == 'en' %}
<img title="English" src="{{ asset('bundles/fkmywebsite/images/UnitedStates.png') }}" alt="English" height="30" width="30"/>
{% elseif locale == 'fr' %}
<img title="Français" src="{{ asset('bundles/fkmywebsite/images/France.png') }}" alt="Français" height="30" width="30"/>
{% endif %}
</div>
</li>
{% endfor %}

听众的工作和帮助很多。我重用脚本在会话
中设置语言环境（带子标签区域）和语言（语言环境代码） <?php
namespace Fer\CaveBundle\EventListener;
use Symfony\Component\HttpKernel\Event\GetResponseEvent;
use Symfony\Component\HttpKernel\KernelEvents;
use Symfony\Component\EventDispatcher\EventSubscriberInterface;
use Symfony\Component\HttpFoundation\Session\Session;
use Symfony\Component\DependencyInjection\ContainerInterface;
class LocaleListener implements EventSubscriberInterface
{
private $defaultLocale;
private $locales;
public function __construct($defaultLocale='es', ContainerInterface $container)
{
//values from configuration of my bundle
$backend = $container->getParameter('cave.backend');
$this->locales = $backend['_locale'];
// $this->locales = array( 'es'=>'es_ES'
// 'en'=>'en_GB,en_US',
// 'fr'=>'fr_FR,fr_BG'
// );
//default must exists in _locales array. locale_lookup Default: es_ES
$this->defaultLocale = locale_lookup(array_keys($this->locales),
$defaultLocale,
false,
current(explode(',',implode(',',array_values($this->locales)))));
}
public function onKernelRequest(GetResponseEvent $event)
{
$request = $event->getRequest();
$session = $request->getSession();
// Locale Get parameters
if($locale = $request->query->get('_locale'))
{
$this->setLocale($request, $session, $locale);
return;
}
// Locale Post parameters with custom form name
if($locale = $request->request->get('_localeForm'))
{
$this->setLocale($request, $session, $locale['_locale']);
return;
}
// Locale session parameters
if($locale = $session->get('_locale'))
{
$this->setLocale($request, $session, $locale);
return;
}
//Locale in browser
if($locale = $request->getPreferredLanguage()){
$this->setLocale($request, $session, $locale);
return;
}
$this->setLocale($request, $session, $this->defaultLocale);
return;
}
public function setLocale($request,$session,$locale)
{
//search language and lookup, default first locale in language
if(in_array(current(locale_parse($locale)),array_keys($this->locales))){
$locale = locale_lookup(explode(',',$this->locales[current(locale_parse($locale))]),
$locale,
false,
current(explode(',',$this->locales[current(locale_parse($locale))])));
}else{
$locale = $this->defaultLocale;
}
//set session parameter
if($locale!==$session->get('_locale')){
$session->set('_locale',$locale);
$session->set('language', current(locale_parse($locale)));//language code
}
//Set the default PHP locale.(for translations)
$request->setLocale($locale);
//set post parameter
$request->request->set('_locale',$locale);
//set get parameter
$request->query->set('_locale',$locale);
return;
}
static public function getSubscribedEvents()
{
return array(
// must be registered before the default Locale listener
KernelEvents::REQUEST => array(array('onKernelRequest', 17)),
);
}
}
?>
如果发送帖子参数，控制器中的表单：
public function indexAction()
{
$form = $this->get('form.factory')->createNamedBuilder('_localeForm')
->add('_locale', 'choice', array(
'choices' => array('en' => 'english', 'es' => 'Español'),//etc
'required' => true,
))->getForm();
return $this->render(
'myProject:myBundle:index.html.twig',
array('_localeForm' => $form->createView())
);
}
示例树枝形式：
<form action="" method="post" {{ form_enctype(_localeForm) }}>
{{ form_widget(_localeForm)}} <br><br>
<input type="submit" value="Enviar" />
{{ form_rest(_localeForm) }}
</form>
在url中发送语言环境，如果从具有twig函数的配置中获取语言环境数组，则更好：
{% for locale in ('fer_cave.backend._locale'|caveParam)|keys %}
<li {% if locale == app.session.get('language') %}class="active" style="color: red"{% endif %}>
{#<a href="{{path(app.request.get('_route'), {'_locale': locale}) }}">{{ locale }}</a>#}
{% set route = app.request.get('_route') %}
{% set route_params = app.request.get('_route_params') %}
<a href="{{ path(route, route_params | merge({ '_locale': locale })) }}">{{ locale }}</a>
{% endfor %}
{#
Locale in session: {{app.session.get('_locale')}}<br>
Language in session: {{app.session.get('language')}}<br>
Locale as get param: {{app.request.get('_locale')}}<br>
Locale as post {{app.request.request.get('_locale')}}
#}
如果要从捆绑配置中检索区域设置，请将serviceContainer添加到侦听器：
<service id="cave.listener" class="Fer\CaveBundle\EventListener\LocaleListener">
<argument>%locale%</argument>
<argument type="service" id="service_container" />
<tag name="kernel.event_subscriber"/>
</service>
为什么不，myProject / myBUndle / DependencyInjection中的示例配置数组
//-------------------ejemplo de backend-------------------//
->arrayNode('backend')
->addDefaultsIfNotSet()
->children()
->arrayNode('_locale')
->addDefaultsIfNotSet()
->children()
->scalarNode('es')->defaultValue('es_ES')->end()//language=>region
->scalarNode('en')->defaultValue('en_GB,en_US')->end()//
->scalarNode('fr')->defaultValue('fr_FR,fr_BG')->end()//
->end()
->end()//end arrayNode('_locale')
->scalarNode('encoding')->defaultValue('UTF-8')->end()
->end()
->end()//end arrayNode('backend')
捆绑包的配置参数中的清洁程序：
fer_cave.backend:
_locale: {es: [es_ES],en: [en_GB,en_US],fr: [fr_FR,fr_BG]}
encoding: UTF-8
cave.frontend:
_locale: {es: es_ES}
encoding: UTF-8
现在我可以使用get，post或browser配置设置Session _locale和语言。
