Extension to the Slim PHP micro-framework version 3 to enable language based routing, i.e. i18n and l10n.
- Slim/Slim (v3)
By terminal:
composer require luism-s/multilingualslimThe $container is used as an interface between the Middleware and the Routes.
The multilinguage middleware injects the following variables into the $container: default_language, available_languages and language.
The first two are variables set by the developer, and the last is set by the middleware itself and indicates the requested language.
use \Psr\Http\Message\ServerRequestInterface as Request;
use \Psr\Http\Message\ResponseInterface as Response;
require '../vendor/autoload.php';
$default_language = 'pt';
$available_languages = ['pt', 'en'];
$app = new \Slim\App();
$container = $app->getContainer();
$app->add( new \MultilingualSlim\LanguageMiddleware($available_languages, $default_language, $container) );
$app->get('/', function (Request $request, Response $response) {
// This works with '/', '/pt' and '/en',
// and prints 'Hello' in each language.
if ($this->language === 'pt') {
return $response->write("Olá Mundo");
} elseif($this->language === 'en') {
return $response->write("Hello World");
}
});
$app->run();You can also use a library to render templates such as php-view. For example:
$container['renderer'] = new \Slim\Views\PhpRenderer("../views/");
$app->get('/home', function (Request $request, Response $response) {
// This works with '/home', '/pt/home' and '/en/home',
// and returns the template views/base.php.
// It also passes the chosen language as an argument accessible from the chosen template.
return $this->renderer->render($response, "base.php", [
"language" => $this->language
]);
});This project is largely influenced by SimoTod/slim-multilanguage, which follows the same philosophy but is made for the version 2 of Slim.
Develop functions to do things such as testing for default language, get current language, compare language, and maybe more.
