Laravel back button
Solution 1:
In Laravel, you can do something like this: <a href="{{ Request::referrer() }}">Back</a> (assuming you're using Blade).
Laravel 4
{{ URL::previous() }}
Laravel 5+
{{ url()->previous() }}
Laravel documentation
Solution 2:
I know this is an oldish question but I found it whilst looking for the same solution. The solution above doesn't appear to work in Laravel 4, you can however use this now:
<a href="{{ URL::previous() }}">Go Back</a>
Hope this helps people who look for this feature in L4
