Passing argument from controller to controller not working - php

Question

Aloha, I'm making a workout manager in which you have a dashboard displaying your 5 last workouts. I have set a form for each one workout for allowing the user to delete any of them. Here the form in the dashboard:
{!! Form::open(['route' => ['dashboard.workout.destroy', $workout->id], 'style' =>'display:inline-block;', 'method' => 'DELETE']) !!}
This route will call this method in WorkoutController.php
public function destroy($id, Request $request)
{
$workout = Workout::findOrFail($id);
$workout->delete();
$message = "Workout deleted successfully!";
return redirect()->route('dashboard.index', ['message' => $message]);
}
And this route will call this method in DashboardController.php
public function index($message = null)
{
$user = Auth::user();
// Workouts
...
// Inbodies
...
// Measures
...
return view('dashboard.index', compact('user','workoutsDesc','workouts','lastInbody','inbodies','measures','lastMeasure','message'));
}
The question is that I'm trying to pass the variable $message from WorkoutController to DashboardController for displaying a successfull alert after deleting a workout, but I don't know how to do it. I have tried with:
return redirect()->action('Dashboard\DashboardController#index', [$message]);
return redirect()->action('Dashboard\DashboardController#index')->with('message', $message);
return redirect()->route('dashboard.index', $message);
But I still trying to find the way for doing it.

Answer 1

First of all, from Laravel 5.1 Documentation:
If your route has parameters, you may pass them as the second argument to the route method
As the message is not a parameter to your route, so you can't pass that. A possible solution can be Flashing data. Check the next controller if the session has that key and contain a value, then add it to a variable and pass to the view.
Hope this works.
