Change on fly language from en_US to fr_FR ZF3

[weierophinney]

Hi everyone, I successfully installed the zend-mvc-i18n in my ZF3 project and when I change the default language manually the message change. But i'm stuck with this: I use this two URL to change on fly the language between en_US and fr_FR <?= $this->url($this->route, array('lang' => 'en_US'));?> <?= $this->url($this->route, array('lang' => 'fr_FR'));?> but it doesn't work et used also a javascript function:

function editLocaleLangue(pRoute) {
    $.ajax({
        type: "POST",
        url: '/language',
        data: "idLangue=" + pRoute,
        dataType: "json",
        success: function (data) {
        },
        complete: function (xhr, status) {
            window.location.reload();
        }
    });
}

also it's not working.

Help please !

@akram82Travel I was looking for it in ZendFramework documentation and I can't find any example. We need update the documentation.

What I have found is: https://stackoverflow.com/questions/25019100/php-zf2-translator-language-switch and, I guess, it should work. Implementation in the constructor probably is not the best idea - I would go with some listener on routing to inject proper locale to translator. Hope it helps until we write better docs for that use case.

Or maybe you - when you resolve your problem - would like to improve the docs and write cookbook how to do it? Thanks!

Did you find any solution for this? I am stuck in exactly the same place as you. The solution provide by webimpress is for zf2 which is different. I would appreciate any help in here. Thanks

I will create a cookbook recipe for this topic which includes a listener like the following:

namespace Application\Listener;

use Locale;
use Zend\EventManager\AbstractListenerAggregate;
use Zend\EventManager\EventManagerInterface;
use Zend\Mvc\MvcEvent;

class LocaleListener extends AbstractListenerAggregate
{
    private const REGEX_LOCALE = '#^(?P<locale>[a-z]{2,3}([-_][a-zA-Z]{2}|))#';
    private const DEFAULT_LOCALE = 'de_DE';

    /**
     * @inheritDoc
     */
    public function attach(EventManagerInterface $events, $priority = 1) : void
    {
        $this->listeners[] = $events->attach(
            MvcEvent::EVENT_DISPATCH,
            [
                $this,
                'setLocale',
            ]
        );
    }

    public function setLocale(MvcEvent $event) : void
    {
        // Get and check the route match object
        $routeMatch = $event->getRouteMatch();
        if (! $routeMatch) {
            $this->setDefaultLocale();
            return;
        }

        // Get and check the parameter for current locale
        $locale = $routeMatch->getParam('locale');
        if (! $locale
            || ! preg_match(self::REGEX_LOCALE, $locale, $matches)
        ) {
            $this->setDefaultLocale();
            return;
        }

        Locale::setDefault(Locale::canonicalize($matches['locale']));
    }

    private function setDefaultLocale() : void
    {
        Locale::setDefault(self::DEFAULT_LOCALE);
    }
}

The listener can be initialized in the method onBootstrap of a module class and the parameter locale can be added to the route(s).
