return redirect with code example

Example 1: previous url laravel

1. The cleanest way seems to be using the url() helper:
	{{ url()->previous() }}

2. URL::previous() works for me in my Laravel 5.1 project. Here is Laravel 5.1 
  doc for previous() method, which is accessible through URL Facade.

3. You can still try alternatives, in your views you can do:

	{{ redirect()->getUrlGenerator()->previous() }}
						OR
	{{ redirect()->back()->getTargetUrl() }}

Example 2: return redirect with message laravel

Route::post('user/profile', function () {
    // Update the user's profile...

    return redirect('dashboard')->with('status', 'Profile updated!');
});
