Symfony2 locale 语言整页事件监听器 [英] Symfony2 locale languages whole page event listener
问题描述
我需要创建一个像 facebook lang 系统这样的系统，当用户点击语言时，例如 france('fr') 页面将重新加载，并且将显示 messages.fr.yml 中的所有内容...
我试图制作类似 /language/{localExtension} 的路线，但是当我在那里 setLocale 然后重定向它没有用...我不知道我假设它只是针对某个页面不是全球性的?因为当我在控制器顶部设置 setLocale('fr') 时，它会起作用......
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...
我在使用 www.example.com/contact/en、/contact/fr 等时发现了一些文章
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...
但我想要 /contact 和以前选择的语言显示的内容.或者当用户没有改变它时默认'en'就像现在......
I found some articles when is using the www.example.com/contact/en, /contact/fr etc
我整天都在谷歌上搜索，我认为应该用...服务=>监听器和...在kernel.request上完成?或类似的东西.
But i want /contact and content displayed from previous chosen language. Or default 'en' like now when user didn't change it...
这里有一个有趣的链接 Symfony2 错误的语言环境检测? 我认为这就是我需要的?或者?我尝试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式:/
I was googling all day and i think it should be done with... service => listener and... on kernel.request? or something like that.
推荐答案
是的，出于某种原因您需要使用侦听器:
Yes for some reason you need to use a listener:在你的 service.xml 中注册你的监听器:
<?php
namespace YourBundleListener;
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)),
);
}
}
?>
Register your listener in your service.xml:如何在树枝模板中实现语言切换器的示例:
<service id="my.listener" class="YourBundleListenerLocaleListener">
<argument>%locale%</argument>
<tag name="kernel.event_subscriber"/>
</service>
