Zend Framework 2中的MultiLingual站点 - 从URL参数设置setLocale（）的值

Question

Below is what I have done so far -

In Application Module - module.config.php -

'service_manager' => array(
    [....],
    'aliases' => array(
        'translator' => 'MvcTranslator',
    ),
),
'translator' => array(
    'locale' => 'en_US',
    'translation_file_patterns' => array(
        array(
            'type' => 'gettext',
            'base_dir' => __DIR__ . '/../language',
            'pattern' => '%s.mo',
        ),
    ),
),

In Album Module - module.config.php -

'router' => array(
    'routes' => array(
        'album' => array(
            'type'    => 'segment',
            'options' => array(
                'route'    => '[/:lang]/album[/:action][/:id]',
                'constraints' => array(
                    'lang' => '[a-zA-Z]*',
                    'action' => '[a-zA-Z][a-zA-Z0-9_-]*',
                    'id'     => '[0-9]+',
                ),
                'defaults' => array(
                    'controller' => 'Album\Controller\Album',
                    'action'     => 'index',
                ),
            ),
        ),
    ),
),

In Album Module - Module.php -

public function onBootstrap(MvcEvent $e) {
    $sm = $e->getApplication()->getServiceManager();

    $router = $sm->get('router');
    $request = $sm->get('request');
    $matchedRoute = $router->match($request);
    $params = $matchedRoute->getParams();

    if(isset($params['lang']) && $params['lang'] !== '') {
        $translator = $e->getApplication()->getServiceManager()->get('translator');
        //or
        //$translator = $e->getApplication()->getServiceManager()->get('MvcTranslator');

        if($params['lang'] == 'en')
            $translator->setLocale('en_US');
        elseif($params['lang'] == 'fr')
            $translator->setLocale('fr_FR');
        else
            $translator->setLocale('en_US');
    }
}

In view -

echo $this->translate('Home');

Note: URL - http://zf2-tutorial.localhost/fr/album, works just fine. The translation is successful.

---

Query -

$translator->setLocale('en'); seems to be working with ZF1 but not with ZF2.

I need to know whether there is any way to directly set the URL param value like $translator->setLocale($params['lang']); rather then long if-else or switch statements.

Some sites might be in 20 or more languages.

Thanks in advance.

Simple answer: use SlmLocale. I wrote the module to implement locale detection DRY and for different use cases.

Don't try to fit the localization into your routes. This allows you to have translatable routes as you detect the locale before routing. Also, it helps you enormously to change locale with different URIs.

A mistake you made in your process is that you grab the route match from the event during bootstrap. However, bootstrap occurs before routing, so you can't get the route match parameters at that stage.

TL;DR: checkout SlmLocale, it should help you with all your problems.
