Laravel: Locale Session: Controller gets Parameter to change it but it cant. U have to hardcode it
提问by patricio
I tried to create a Form and do away with Ajax. Yes, the form at least does send the parameter down to the Controller as I var_dumped it and exited in order to see if it had gotten the new value, and yes it did, but guess what? and here is the question:
我试图创建一个表单并取消 Ajax。是的，表单至少确实将参数发送到控制器，因为我将它转储并退出以查看它是否获得了新值，是的，确实如此，但你猜怎么着？这是问题：
Even though the Input::get('locale') received from the Controller is the one I sent from the Form, the following code can't get to change the Session.
即使从控制器接收到的 Input::get('locale') 是我从表单发送的，下面的代码也无法更改会话。
Controller:
控制器：
public function languagechooser()
{
$session = \Input::get('language');
var_dump($session);exit;
\Session::set('locale',$session);
return\Redirect::back();
}
The only way to change the session is hardcoding it, like this (notice the 'en':
更改会话的唯一方法是对其进行硬编码，如下所示（注意“en”：
public function languagechooser()
{
$session = \Input::get('language');
var_dump($session);exit;
\Session::set('en');
return\Redirect::back();
}
but I dont understand why. Once it receives it from the variable, it should stay in there, but it looks that it does not. Is it a variable after all? But on youtube phpacademy does the same thing (just using Laravel 4) while I use 5
但我不明白为什么。一旦它从变量中接收到它，它应该留在那里，但看起来它没有。毕竟它是一个变量吗？但是在 youtube 上 phpacademy 做同样的事情（只使用 Laravel 4）而我使用 5
and the Form, just a Form
和表格，只是一个表格
<form action="{!!URL::route('languagechooser')!!}" method ="post">
<select class="form-control" name="language">
<option value="fr">fr</option>
<option value=en">en</option>
<option value="es">es</option>
<option value="ru">ru</option>
<option value="it">it</option>
<option value="de">de</option>
</select>
<button class="btn btn-primary pull-right" type="submit">Search</button>
{!!Form::token()!!}
</form>

Route::post('languagechooser', [

@if( Session::has('locale') )
Locale: {{ Session::get('locale') }} <br>

@else
no session locale set
@endif

Controller - WelcomeController.php
控制器 - WelcomeController.php
public function changeLanguage()
{
$lang = \Input::get('language');
\Session::put('locale', $lang);
return \Redirect::back();
}
Create middleware: php artisan make:middleware Locale
创建中间件： php artisan make:middleware Locale
Middleware Locale.php
中间件 Locale.php
<?php namespace App\Http\Middleware;
use Closure;
use Session;
use App;
use Config;
class Locale {
/**
* Handle an incoming request.
*
* @param \Illuminate\Http\Request $request
* @param \Closure $next
* @return mixed
*/
public function handle($request, Closure $next)
{
$language = Session::get('locale', Config::get('app.locale'));
App::setLocale($language);
return $next($request);
}
}
Added this: 'App\Http\Middleware\Locale'to $middlewarearray in the Http\Kernel.phpfile so it's loaded on each request.
添加了这个：'App\Http\Middleware\Locale'到文件中的$middleware数组，Http\Kernel.php以便在每个请求时加载它。
protected $middleware = [
'Illuminate\Foundation\Http\Middleware\CheckForMaintenanceMode',
'Illuminate\Cookie\Middleware\EncryptCookies',
'Illuminate\Cookie\Middleware\AddQueuedCookiesToResponse',
'Illuminate\Session\Middleware\StartSession',
'Illuminate\View\Middleware\ShareErrorsFromSession',
'App\Http\Middleware\VerifyCsrfToken',
'App\Http\Middleware\Locale',
];
resources/lang/en/test.php
资源/语言/en/test.php
return [
'message' => 'hello'
];
resources/lang/es/test.ph`
资源/语言/es/test.ph`
return [
'message' => 'hola'
];
