laravel return back with data code example

Example 1: laravel return redirect to named route

return redirect()->route('login');

Example 2: 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 3: return back in blade laravel

{{ url()->previous() }}
