Laravel：会话未保存

Question

So I've read through all the Laravel sessions information and all the stackoverflow questions about Laravel sessions but it's just no help.

Im trying to store the username when I'm logging in, and I want it to show the whole time I'm logged in on a page. Now when I login I get to the main page and the username shows, and I go back to login, which redirects me to the main page and the username is not there anymore. The code I'm using:

Session::put('username', Input::get('username'));
$value = Session::get('username');
return View::make('main')->with('username',$value);

and then in my main.blade.php:

@if(!empty($username))
     {{$username}}
@endif

I have no idea what I'm doing wrong. I'm doing it exactly like all the examples. What am I doing wrong here?

If you're not doing it already, you should make use of Laravels Auth . Then you don't have to handle the stuff yourself and can just do this to retrieve the username:

Auth::user()->username;

Edit

The actual problem here weren't your sessions but the fact that you only passed the $username to the view in your one controller and not all the time when your rendered it.

If you want some property of the current user, definitely use Auth::user()->username . If you have other session values you can access them directly in the view using:

{{ Session::get('foo'); }}

Another approach are view composers. They let you pass something to the view every time it gets rendered:

View::composer('main', function($view){
    $view->with('foo', Session::get('foo'));
});

You can put this code in app/filters.php or create a new app/composers.php and include it at the end of app/start/global.php with:

require app_path().'/composers.php';

Now the variable always available in main.blade.php by just:

{{ $username }}
