Easy i18n localization for Laravel 4, an useful tool to combine with Laravel localization classes.
Add Laravel Localization to your composer.json file.
"mcamara/laravel-localization": "dev-master"
Run composer install to get the latest version of the package.
It's recommended that you use Composer, however you can download and install from this repository.
Laravel Localization comes with a service provider for Laravel 4. You'll need to add it to your composer.json as mentioned in the above steps, then register the service provider with your application.
Open app/config/app.php and find the providers key. Add LaravelLocalizationServiceProvider to the array.
...
'Mcamara\LaravelLocalization\LaravelLocalizationServiceProvider'
...You can also add an alias to the list of class aliases in the same app.php
...
'LaravelLocalization' => 'Mcamara\LaravelLocalization\Facades\LaravelLocalization'
...To finish, publish the configuration file using the command php artisan config:publish mcamara/laravel-localization in your laravel root path. This will create the following file app/config/packages/mcamara/laravel-localization/config.php, containing the most common setting options.
Laravel Localization uses the URL given for the request. In order to achieve this purpose, a group should be added into the routes.php file. It will filter all pages that must be localized.
// app/routes.php
Route::group(array('prefix' => LaravelLocalization::setLanguage()), function()
{
/** ADD ALL LOCALIZED ROUTES INSIDE THIS GROUP **/
Route::get('/', function()
{
return View::make('hello');
});
Route::get('test',function(){
return View::make('test');
});
});
/** OTHER PAGES THAT SHOULD NOT BE LOCALIZED **/Once this group is added to the routes file, a user can access all languages added into the 'languagesAllowed' ('en' and 'es' by default, look at the config section to change that option). For example, a user can now access to two different languages, using the following addresses:
http://url-to-laravel/en
http://url-to-laravel/es
http://url-to-laravel
If the language is not present in the url or it is not defined in the 'languagesAllowed' array, the system will take the application default language (by default) or the user's browser default language (if defined in config file).
Once the language is defined, the language variable will be stored in a session, so it is not necessary to write the /lang/ section in the url after defining it once, using the last known language for the user. If the user accesses to a different language this session value would be changed, translating any other page he visits with the last chosen language.
Templates files and all language files should follow the Lang class.
Moreover, this package includes a filter to redirect all "non-languaged" routes to a "languaged" one (thanks to Sangar82).
So, if a user accesses to http://url-to-laravel/test and the system have this filter actived and 'en' as a current language for this user, it would redirect (301) him automatically to http://url-to-laravel/en/test. This is mainly used to avoid duplicate content and improve SEO performance.
// app/routes.php
Route::group(
array(
'prefix' => LaravelLocalization::setLanguage(),
'before' => 'LaravelLocalizationRedirectFilter' // LaravelLocalization filter
),
function()
{
/** ADD ALL LOCALIZED ROUTES INSIDE THIS GROUP **/
Route::get('/', function()
{
return View::make('hello');
});
Route::get('test',function(){
return View::make('test');
});
});
/** OTHER PAGES THAT SHOULD NOT BE LOCALIZED **/In order to active it, you just have to attach this filter to the routes you want to be accessible localized.
If you want to hide the default language but always show other languages in the url, switch the 'hideDefaultLanguageInRoute' config value to true. Once it's true, if the default language is english all url containing /en/ would be redirected to the same url without this fragment but mantaining the language (all the website will be in english).
This package comes with some useful functions, like:
/**
* Returns html with language selector
*
* @param boolean $abbr Should languages be abbreviate (2 characters) or full named?
* @param string $customView Which template should the language bar have?
*
* @return string Returns an html view with a language bar
*/
public function getLanguageBar($abbr = false, $customView = 'mcamara/laravel-localization/languagebar')
//Should be called in a view like this:
{{ LaravelLocalization::getLanguageBar(optional boolean $abbr, optional string $customView) }}It returns an html string with <a> links to the very same page into another allowed language. Having english, catalan and spanish allowed as languages, being in url-to-laravel/test and english as the current language, this function would return...
<ul class="laravel_language_chooser">
<li class="active">EN</li>
<li><a rel="alternate" hreflang="ca" href="http://url-to-laravel/ca/test">CA</a></li>
<li><a rel="alternate" hreflang="es" href="http://url-to-laravel/es/test">ES</a></li>
</ul>If you are using translation routes, be sure that all keys exist for all languages. Otherwise, the language bar would not show the untranslated routes but it would show all the other links.
You can also define which view you want to use to show the language bar. If you want to create your own language bar from the example given in the package, you should publish it using the command php artisan view:publish mcamara/laravel-localization, it would create a language bar template (take a look at view section). If you rename the view, you should pass the new name as the $customView variable when the languageBar function is called, this function will look at this custom view within the app/view folder. In case this file does not exist, the language bar function would show the default bar.
/**
* It returns an URL without language (if it has it)
*
* @param string $route URL to clean, if false, current url would be taken
*
* @return string Route with no language path
*/
public function getCleanRoute($route = null)
//Should be called in a view like this:
{{ LaravelLocalization::getCleanRoute(optional string $route) }}It returns a string, giving url passed through the function clean of any language section.
/**
* Returns an URL adapted to $language language
*
* @param string $localeCode Language to adapt
* @param string $route URL to adapt, if false, current url would be taken
*
* @return string URL translated
*/
public function getLocalizedURL($localeCode, $route = null)
//Should be called in a view like this:
{{ LaravelLocalization::getLocalizedURL(string $lang, optional string $route) }}It returns a string, translated to the desired language. If you pass a route to the function it has to be written in the current language, otherwise the function won't return the desired result.
/**
* Returns an URL adapted to the route name and the language given
*
* @param string $language Language to adapt
* @param string $transKeyName Translation key name of the url to adapt
* @param array $attributes Attributes for the route (only needed if transKeyName needs them)
*
* @return string URL translated
*/
public function getURLFromRouteNameTranslated($language, $transKeyName = null, $attributes = array())
//Should be called in a view like this:
{{ LaravelLocalization::getURLFromRouteNameTranslated(string $lang, optional string $transKeyName, optional array $attributes) }}It returns a string, translated to the desired language using the translation key given. If the translation key does not exist in the language given, this function will return false.
/**
* Return an array of all supported Locales
*
* @return array
*/
public function getSupportedLocales()
//Should be called like this:
{{ LaravelLocalization::getSupportedLocales() }}This function will return all supported languages and it's properties as array.
/**
* Set and return current language
*
* @param string $locale Language to set the App to (optional)
*
* @return string Returns language (if route has any) or null (if route has not a language)
*/
public function setLanguage($locale = null)
//Should be called in a view like this:
{{ LaravelLocalization::setLanguage(optional string $lang) }}This function will change the application current language, if the language is not passed through its call, it would take the language from the session (if stored previously), browser language or the default application language (depending on your config file).
The function have to be called in the prefix of any route that should be translated (see Filters sections for further information).
/**
* Returns current language direction
*
* @return string current language direction
*/
public function getCurrentLanguageDirection()
//Should be called in a view like this:
{{ LaravelLocalization::getCurrentLanguageDirection() }}This function will return current language direction as string (ltr/rtl).
/**
* Returns current language script
*
* @return string current language script
*/
public function getCurrentLanguageScript()
//Should be called in a view like this:
{{ LaravelLocalization::getCurrentLanguageScript() }}This function will return current language script as string (Latin/Cyrillic/Arabic/ ..etc).
You can edit the default view for the language bar executing php artisan view:publish mcamara/laravel-localization.
This command will create a blade view in your app/views folder containing the default code for the language bar, edit it to style and edit your language bar that suits you the best.
New in version 0.5
You can adapt your URLs depending on the language you want to show them. For example, http://url/en/about and http://url/es/acerca (acerca is about in spanish) or http://url/en/view/5 and http://url/es/ver/5 (view == ver in spanish) would be redirected to the same controller using the proper filter and setting up the translation files as follows:
// app/routes.php
Route::group(
array(
'prefix' => LaravelLocalization::setLanguage(),
'before' => 'LaravelLocalizationRoutes' // Route translate filter
),
function()
{
/** ADD ALL LOCALIZED ROUTES INSIDE THIS GROUP **/
Route::get('/', function()
{
// This routes is useless to translate
return View::make('hello');
});
Route::get(LaravelLocalization::transRoute('routes.about'),function(){
return View::make('about');
});
Route::get(LaravelLocalization::transRoute('routes.view'),function($id){
return View::make('view',array('id'=>$id));
});
});
/** OTHER PAGES THAT SHOULD NOT BE LOCALIZED **/In the routes file you just have to add the LaravelLocalizationRoutes filter and the LaravelLocalization::transRoute function to every route you want to translate using the translation key.
Tip: If you want to use this filter with other filters (like LaravelLocalizationRedirectFilter) you just have to join them in the Laravel way, using | (eg: 'before' => 'LaravelLocalizationRoutes|LaravelLocalizationRedirectFilter' )
Then you have to create the translation files and add there every key you want to translate. I suggest you to create a routes.php file inside your app/lang/language_abbreviation folder. For the previous example, I have created two translations files, these two files would look like:
// app/lang/en/routes.php
return array(
"about" => "about",
"view" => "view/{id}", //we add a route parameter
// other translated routes
); // app/lang/es/routes.php
return array(
"about" => "acerca",
"view" => "ver/{id}", //we add a route parameter
// other translated routes
);Once files are saved, you can access to http://url/en/about , http://url/es/acerca , http://url/en/view/5 and http://url/es/ver/5 without any problem. The getLanguageBar function would work as desired and it will translate the routes to all translated languages (don't forget to add any new route to the translation file).
By default only english and spanish are allowed but it can be changed using config.php file that is located at app/config/packages/mcamara/laravel-localization/config.php . If this file does not exist, use the following artisan command php artisan config:publish mcamara/laravel-localization in order to create it.
This file have some interesting configuration settings (as the allowed languages or browser language detection, among others) feel free to play with it, all variables are self-explained.
