Laravel passing username parameter to controller from user.blade.php -

hi on website have profile username parameter root/user/{username}. planning add button block user. problem when other user click block button, button stuffs in check.php controller doesn't pass user/{username} parameter need in if statements. question how can pass {username} parameter user.blade.php check.php controller?

as not seeing code here, seems need, have create route pointing controller method , route redirect users when successufully blocked:

route::get('user/block/{username}', 'blockusercontroller@block');  route::get('userblocked', 'blockusercontroller@blocked'); 

and controller itself:

class blockusercontroller extends controller {      public function block($username)      {         $user = user::where('username', $username);          $user->blocked = true;          $user->save();          return redirect::to('userblocked');     }      public function blocked($username)      {         return view::make('user.blocked');     }  } 

and if click button pointing route:

http://application.com/user/block/user3398940 

it blocked.

if want go little more advanced in laravel, can use dependency injection , remove code controller:

class blockusercontroller extends controller {      private $user;      public function __construct(user $user)          $this->user = $user;     }      public function block($username)      {         if ($user->block($username))         {             return redirect::to('userblocked');         }          return redirect::back()->with('message', 'user not found');     }      public function blocked($username)      {         return view::make('user.blocked');     }  } 

and user model have have block method:

class user extends eloquent {      public function block($username)      {         if ($user = $this->newquery()->where('username', $username))         {             $user->blocked = true;              return $user->save();         }          return false;     }  }
