This extended Lang class supports localized language URLs

http://domain/lang1/controller/method
http://domain/lang2/controller/method

Only Lang class is changed and without introducing any side-effects thus making it fully backward compatible and keeping FuelPHP API same, but adding additional functionality.

You can install it with composer or just copy lang.php to your app/classes/

then in your app/bootstrap.php add

Autoloader::add_class('Lang', VENDORPATH . 'davispuh/fuelphp-lang/classes/lang.php');

or if you copied it then

Autoloader::add_class('Lang', APPPATH . 'classes/lang.php');

To use this extended Lang class there are required few code changes, but nothing much.

1. all links which are supposed to be for same language must be replaced with Lang::localized($uri), eg. <a href="<?php echo Lang::localized('/blog/article/')?>"/>Article</a> (Note: currently localized doesn't support schema or relative urls, and it expects that uri starts with / but it can be implemented if needed, now can do just 'https://domain'.Lang::localized('/blog/article/'))
2. make links which change language. either use Lang::localized('/blog/article/','ru') or directly write <a href="/ru">RU</a>
3. in app config.php add available languages 'languages' => Array('en', 'ru')
4. change routes.php config to also include localized routing.

Will need routes for both cases when language is included in URI and when isn't. So will need to add another _root_ ie. $routes[$langs] and all other routes prefixed with $routes[(({$langs})/)?route]

There's 4 possible configurations.

SEO friendly. Default language without any prefix. ie. http://domain/controller and all other languages http://domain/lang/controller. BUT http://domain/default_lang/controller returns 404

config.php: 'language' => 'en' // specify which language will be served as default. without included in URL

routes.php

<?php

$languages = Config::get('languages');
unset($languages[0]);
$langs = implode('|', $languages);

return array(
'_root_' => 'welcome/index', // The default route
"({$langs})" => 'welcome/index', // The default route in other language
"(({$langs})/)?hello(/:name)?" => array('welcome/hello', 'name' => 'hello'),
);

Default language without any prefix. ie. http://domain/controller, BUT http://domain/default_lang/controller will still work.

everything same as previous, just without unset($languages[0]);

All languages http://domain/lang/controller. BUT http://domain/controller will return 404. There's exception to _root_, it will give default language (language_fallback).

config.php: 'language' => '' // no default language, MUST be in URL 'language_fallback' => 'en' // Fallback language if language isn't in URL

routes.php

<?php

$langs = implode('|', Config::get('languages'));

return array(
'_root_' => 'welcome/index', // The default route
"({$langs})" => 'welcome/index', // The default route in other language
"(({$langs})/)?hello(/:name)?" => array('welcome/hello', 'name' => 'hello'),
);

Make your own routes, unlimited possibilities. Maybe you don't have some article in that language? No problem, just give in default language or give page informing that it's not available.
