什么是Laravel中的交换语言的最佳逻辑?

题
我正在使用Laravel本地化来提供两种不同的语言。我已经设置了所有的路径,而mydomain.com/en/bla一起提供英语并存储“en”会话变量,而mydomain.com/he/bla提供希伯来语并存储“他”的会话变量。但是,我无法弄清楚提供语言切换链路的体面方式。这是怎么回事?
解决方案
我通过将其添加到routes.php:
中的过滤器来解决问题// Default language ($lang) & current uri language ($lang_uri)
$lang = 'he';
$lang_uri = URI::segment(1);
// Set default session language if none is set
if(!Session::has('language'))
{
Session::put('language', $lang);
}
// Route language path if needed
if($lang_uri !== 'en' && $lang_uri !== 'he')
{
return Redirect::to($lang.'/'.($lang_uri ? URI::current() : ''));
}
// Set session language to uri
elseif($lang_uri !== Session::get('language'))
{
Session::put('language', $lang_uri);
}
// Store the language switch links to the session
$he2en = preg_replace('/he\//', 'en/', URI::full(), 1);
$en2he = preg_replace('/en\//', 'he/', URI::full(), 1);
Session::put('he2en', $he2en);
Session::put('en2he', $en2he);
. 其他提示
这是我最初发布在Laravel论坛上的帖子,但也许它会帮助其他人,所以我也在这里发布。
我对我的应用程序构建一个简单的语言切换器,以及论坛的信息有些麻烦,有点旧的(一些帖子),所以我制作了这个简单的代码,使其成为改变语言的超级代码app在飞行。
我的视图中的语言字符串如下:
{{ __('languagefile.the_language_string'); }}
.
我用网址获得语言,我认为这是最好的方法,它对SEO和人们共享的链接有益。示例:
www.myapp.com/fi/support (Finnish)
www.myapp.com/en/support (English)
www.myapp.com/sv/support (Swedish)
.
好的,问题是我想要一个简单的方法来瞬间改变语言,而无需混淆会话和cookie。九世纪我是如何制作的:
在您的图书馆文件夹中制作一个名为 chooselang.php
的库插入此代码:
class Chooselang extends HTML {
/**
* Generate a Language changer link.
*
* <code>
* // Generate a link to the current location,
* // but still change the site langauge on the fly
* // Change $langcode to desired language, also change the Config::set('application.language', 'YOUR-LANG-HERE')); to desired language
* // Example
* echo Chooselang::langslug(URI::current() , $langcode = 'Finnish' . Config::set('application.language', 'fi'));
* </code>
*
* @param string $url
* @param string $langcode
* @param array $attributes
* @param bool $https
* @return string
*/
public static function langslug($url, $langcode = null, $attributes = array(), $https = null)
{
$url = URL::to($url, $https);
if (is_null($langcode)) $langcode = $url;
return '<a href="'.$url.'"'.static::attributes($attributes).'>'.static::entities($langcode).'</a>';
}
}
此后,您已准备好获取您的URL切换器URL:s生成。只要将任何其他刀片链接添加它们即可添加它们。
如何生成芬兰语,瑞典语和英语(带刀片)的链接
{{ Chooselang::langslug(URI::current() , $langcode = 'Fin' . Config::set('application.language', 'fi')); }}
{{ Chooselang::langslug(URI::current() , $langcode = 'Swe' . Config::set('application.language', 'sv')); }}
{{ Chooselang::langslug(URI::current() , $langcode = 'Eng' . Config::set('application.language', 'en')); }}
.
以上将生成URL:s始终在当前页面上,并将LANG SLUG更改为您想要的LANG SLUG。这样语言更改为您想要的语言,用户自然地保持在同一页面上。默认的语言SLUG从未添加到URL。
生成的URL看起来像:
<a href="http://localhost/laravel/public/support">Fin</a>
<a href="http://localhost/laravel/public/sv/support">Swe</a>
<a href="http://localhost/laravel/public/en/support">Eng</a>
.
ps。如果将它们添加到主模板文件中,链接是特别有用的。
您可以进行手动语言更改的路由,例如:
Route::get('translate/(:any)', 'translator@set');
set
控制器中的translator
操作中可以改变会话,具体取决于通过URL传递的语言代码。
您还可以使用
更改配置设置 Config::set('application.language', $url_variable');
控制器示例 - translate.php
public function action_set($url_variable)
{
/* Your code Here */
}

这个问题仍然来自谷歌搜索,所以如果你使用的是你使用的laravel 4或5,以及mcamara / laravellcalization是答案。
<ul>
<li class="h5"><strong><span class="ee-text-dark">{{ trans('common.chooselanguage') }}:</span></strong> </li>
@foreach(LaravelLocalization::getSupportedLocales() as $localeCode => $properties)
<li>
<a rel="alternate" hreflang="{{$localeCode}}" href="{{LaravelLocalization::getLocalizedURL($localeCode) }}">
<img src="/img/flags/{{$localeCode}}.gif" /> {{{ $properties['native'] }}}
</a>
</li>
@endforeach
</ul>
.
请注意,此示例显示标志(公共/ img / flags / {{locale}}。gif),并使用它需要一点.css,但如果您可以修改它以显示文本想要...
fyi。Mcamara / LaravellCalization文档有示例和很多帮助者,所以通过GitHub上的文档看。( https://github.com/mcamara/laravel -localization
尝试使用会话。像这样的东西:
控制器:
class Language_Controller extends Base_Controller {
function __construct(){
$this->action_set();
parent::__construct();
}
private function checkLang($lang = null){
if(isset($lang)){
foreach($this->_Langs as $k => $v){
if(strcmp($lang, $k) == 0) $Check = true;
}
}
return isset($Check) ? $Check : false;
}
public function action_set($lang = null){
if(isset($lang) && $this->checkLang($lang)){
Session::put('lang', $lang);
$this->_Langs['current'] = $lang;
Config::set('application.language', $lang);
} else {
if(Session::has('lang')){
Config::set('application.language', Session::get('lang'));
$this->_Langs['current'] = Session::get('lang');
} else {
$this->_Langs['current'] = $this->_Default;
}
}
return Redirect::to('/');
}
}
.
在Route.php:
Route::get('lang/(:any)', 'language@set');
. I've been doing it like this:
$languages = Config::get('lang.languages'); //returns array('hrv', 'eng')
$locale = Request::segment(1); //fetches first URI segment
//for default language ('hrv') set $locale prefix to "", otherwise set it to lang prefix
if (in_array($locale, $languages) && $locale != 'hrv') {
App::setLocale($locale);
} else {
App::setLocale('hrv');
$locale = null;
}
// "/" routes will be default language routes, and "/$prefix" routes will be routes for all other languages
Route::group(array('prefix' => $locale), function() {
//my routes here
});

What I'm doing consists of two steps: I'm creating a languages table which consists of these fields:
id | name | slug
which hold the data im gonna need for the languages for example
1 | greek | gr
2 | english | en
3 | deutch | de
The Language model I use in the code below refers to that table.
So, in my routes.php I have something like:
//get the first segment of the url
$slug = Request::segment(1);
$requested_slug = "";
//I retrieve the recordset from the languages table that has as a slug the first url segment of request
$lang = Language::where('slug', '=', $slug)->first();
//if it's null, the language I will retrieve a new recordset with my default language
$lang ? $requested_slug = $slug : $lang = Language::where('slug', '=', **mydefaultlanguage**')->first();
//I'm preparing the $routePrefix variable, which will help me with my forms
$requested_slug == ""? $routePrefix = "" : $routePrefix = $requested_slug.".";
//and I'm putting the data in the in the session
Session::put('lang_id', $lang->id);
Session::put('slug', $requested_slug);
Session::put('routePrefix', $routePrefix );
Session::put('lang', $lang->name);
And then I can write me routes using the requested slug as a prefix...
Route::group(array('prefix' => $requested_slug), function()
{
Route::get('/', function () {
return "the language here is gonna be: ".Session::get('lang');
});
Route::resource('posts', 'PostsController');
Route::resource('albums', 'AlbumsController');
});
This works but this code will ask the database for the languages everytime the route changes in my app. I don't know how I could, and if I should, figure out a mechanism that detects if the route changes to another language.
Hope that helped.
