laravel url

1// Get the current URL without the query string...
2echo url()->current();
3
4// Get the current URL including the query string...
5echo url()->full();
6
7// Get the full URL for the previous request...
8echo url()->previous();

11. The cleanest way seems to be using the url() helper:
2	{{ url()->previous() }}
3
42. URL::previous() works for me in my Laravel 5.1 project. Here is Laravel 5.1 
5  doc for previous() method, which is accessible through URL Facade.

73. You can still try alternatives, in your views you can do:
8
9	{{ redirect()->getUrlGenerator()->previous() }}
10						OR
11	{{ redirect()->back()->getTargetUrl() }}
