Laravel Passing Variable from a controller to another Controller - laravel

Question

I'm trying to pass a variable from a controller to another controller I tried using
Redirect::to('dashboard/'.$ssid.'/')->with(compact('wname'))
but does not work any idea how can I achieve this?
here is my code
Route
Route::get('dashboard/{ssid}/', 'HomeController#showDash');
LoginController
public function post_index()
{
if(Auth::attempt($credentials)){
$users = User::where('username','=',$email)->get();
foreach ($users as $value):
$activated = $value['a_status'];
$wname = $value['wholename'];
endforeach;
if($activated == 1):
$red= Redirect::to('dashboard/'.$ssid.'/')->with(compact('wholename'));
else:
$red= View::make('login');
endif;
return $red;
}
}
HomeController
public function showDash($ssid,$wholename)
{
foreach ($wholename as $userVal):
$fn = $userVal['firstname'];
$ln = $userVal['lastname'];
endforeach;
return View::make('dashboard')->with(compact('fn'));
}
The error I'm having is that Missing argument 2 for HomeController::showDash() as per laravel's debugger..

Updated answer based on the comments:
public function post_index()
{
if(Auth::attempt($credentials)){
$users = User::where('username','=',$email)->get();
foreach ($users as $value){
$activated = $value['a_status'];
$wname = $value['wholename'];
}
if($activated == 1) {
Redirect::to('dashboard/'.$ssid.'/')->with(['wholename' => $wholename]);
}
return View::make('login');
}
public function showDash($ssid)
{
$wholename = (Session::has('wholename')) ? Session::get('wholename') : [];
foreach ($wholename as $userVal) {
$fn = $userVal['firstname'];
$ln = $userVal['lastname'];
}
return View::make('dashboard')->with(compact('fn'));
}
Everything else can stay as is.
Update: fixed erroneous space in 'whole name' (autocorrect did that, sorry).
