Subject

If you configure multiple hosts different from localhost, localization stops working. However, if there is only one host (localhost) and no host-based restrictions in the routes, locale switching works as expected. When there are no host-based restrictions, the PageBundle correctly understands that the locale (e.g., de) is a locale. But if there are two different hosts, it somehow ignores the locale specified in the URL and instead tries to find a route that matches the locale name.

Minimal repository with the bug

I repeated all the steps on the fresh Symfony 6.4 version. If needed, I can upload these changes to Git, but I don't think it's necessary or will be of much help.

Steps to reproduce

1. Create multiple sites. For example:
   | name | relative_path | host | locale |
   | First site EN | | first-site.local | en |
   | First site DE | /de | first-site.local | de |
   | Second site EN | | second-site.local | en |
   | Second site DE | /de | second-site.local | de |

2. Configure routes and bind them to different hosts

3. Run the commands:

• ./bin/console sonata:page:update-core-routes
• ./bin/console sonata:page:create-snapshots

4. Navigate to any page by specifying its locale, for example: first-site.local/de/test-page (or go to the page and switch the language while on it.)

Expected results

The page opens based on the locale specified in the URL.

Actual results

Error: No route found for "GET http://first-site.local/de/test-page"

If someone encounters a similar problem, my solution is to modify the function \Sonata\PageBundle\Site\BaseSiteSelector::getSites() approximately like this (this is a rough example that can and should be improved):

    protected function getSites(Request $request): array
    {
        $pathInfo = $request->getPathInfo();
        $pathLocale = explode('/', $pathInfo)[1] ?? 'en';
        $locale = in_array($pathLocale, ['en', 'de']) ? $pathLocale : 'en';

        return $this->siteManager->findBy([
            'host' => [$request->getHost(), 'localhost'],
            'locale' => $request->get('_locale', $locale),
            'enabled' => true,
        ], [
            'isDefault' => 'DESC',
        ]);
    }
