Symfony3链接以更改区域设置 - Symfony3 link to change locale

Symfony3 link to change locale

本文关键字：区域设置链接 Symfony3 | 更新日期: 2023-09-26

我想创建一个链接，它将在下面的代码中更改locale。

/**
 *
 * @Route("/changelanguage", defaults={"_locale" = "eu"}, name="changelanguage")
 * @Method("GET")
 */
public function changelanguageAction(Request $request) {

    $locale = $request->getLocale();
    if ($locale == "eu") {
        $request->setLocale('es');
        $request->getSession()->set('_locale', 'es');
    } else {
        $request->setLocale('eu');
        $request->getSession()->set('_locale', 'eu');
    }
    return $this->redirect($request->headers->get('referer'));
}

然后，在我的twig base视图中，我使用这个:

<ul class="nav navbar-nav navbar-right">        
    <li><a href="#">{{ app.request.locale }}</a></li>
    {% if  app.request.locale == "eu"%}
        <li><a href="{{ path('changelanguage', {'_locale':'es'}) }}"><img src="{{ asset('bundles/app/img/espanol.png') }}" alt="Castellano"> Castellano</a></li>
    {% else %}
        <li><a href="{{ path('changelanguage', {'_locale':'eu'}) }}"><img src="{{ asset('bundles/app/img/euskara.png') }}" alt="Euskaraz"> Euskara</a></li>
    {% endif %}
    <li>&nbspp;</li>
</ul>

问题是它一直告诉我app.request.locale总是'eu'。我错过什么了吗?

为用户实体添加默认语言，然后创建请求侦听器，检查用户的默认语言并更改它…

This work for me

创建监听器

<?php
namespace UserBundle'EventListener;
use Symfony'Component'DependencyInjection'ContainerInterface;
use Symfony'Component'HttpKernel'Event'GetResponseEvent;
use Symfony'Component'HttpKernel'HttpKernelInterface;
class LanguageListener
{
    private $token_storage;
    private $securityContext;
    private $container;
    public function __construct(ContainerInterface $containerInterface)
    {
        $this->container = $containerInterface;
        $this->securityContext = $this->container->get('security.authorization_checker');
        $this->token_storage = $this->container->get('security.token_storage');;
    }
    public function setLocale(GetResponseEvent $event)
    {
        if (HttpKernelInterface::MASTER_REQUEST !== $event->getRequestType()) {
            return;
        }

        if ($this->securityContext->isGranted('IS_AUTHENTICATED_REMEMBERED')) {
            $userLocale = $this->token_storage->getToken()->getUser()
                ->getCustomer()->getDefaultCodeLanguage();
            if ($userLocale) {
                $request = $event->getRequest();
                $request->setLocale($userLocale);
                $translator = $this->container->get('translator');
                $translator->setLocale($userLocale);
            }
        }

    }
}

services.yml

services:
    language.kernel_request_listener:
        class: UserBundle'EventListener'LanguageListener
        arguments:
            - "@service_container"
        tags:
            - { name: kernel.event_listener, event: kernel.request, method: setLocale }
