Symfony2语言环境语言整页事件监听器

我试图制作类似于/language/{localExtension}的路线，但是当我在那里设置setLocale然后重定向它不起作用...我不知道我是否为某些页面而不是全局设置了它?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等时发现了一些文章但是我想从以前选择的语言中显示/contact和内容.或像现在一样在用户未更改时默认为'en'...我整天都在搜索，我认为应该使用... service => listener和... on kernel.request来完成?或类似的东西.这里有有趣的链接 Symfony2错误的语言环境检测?我认为这是我需要的吗?或者?我试图设置服务并创建侦听器，但出现了一些错误，我什至不知道这是否是创建它的方法:/解决方案是的，由于某些原因，您需要使用侦听器:<?phpnamespace 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中注册您的侦听器:<service id="my.listener" class="Your\Bundle\Listener\LocaleListener"> <argument>%locale%</argument> <tag name="kernel.event_subscriber"/></service>如何在树枝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 %}I need to create a system like the facebook lang system when a user clicks on language to example france('fr') the page will reload and all the content in messages.fr.yml will be displayed...I tried to make route like /language/{localExtension} but when I setLocale there and then redirected it didn't work... I don't know i assuming its just for certain page not global? Because when i set setLocale('fr') at the top of my controller it works...I found some articles when is using the www.example.com/contact/en, /contact/fr etcBut i want /contact and content displayed from previous chosen language. Or default 'en' like now when user didn't change it...I was googling all day and i think it should be done with... service => listener and... on kernel.request? or something like that.Here are intresting link Symfony2 wrong locale detection? i think that's what i need? or? I tried to set service and create listener but some errors appear and i don't even know if this is the way how to create it :/ 解决方案 Yes for some reason you need to use a listener:<?phpnamespace 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)), ); }}?>Register your listener in your service.xml:<service id="my.listener" class="Your\Bundle\Listener\LocaleListener"> <argument>%locale%</argument> <tag name="kernel.event_subscriber"/></service>An example how to implement the language switcher in your twig template:{% 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 %} 这篇关于Symfony2语言环境语言整页事件监听器的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！ 上岸，阿里云！
