Answers for "laravel handle back with message"

laravel return back with success

return redirect()->back()->with('message', 'IT WORKS!');

Displaying message if it exists:

@if(session()->has('message'))
    <div class="alert alert-success">
        {{ session()->get('message') }}
    </div>
@endif

back() with errors in laravel

return Redirect::back()->withErrors(['msg' => 'The Message']);
inside you view
@if($errors->any())
<h4>{{$errors->first()}}</h4>
@endif
