Pass old input after Form Request validation in laravel 5
$username = Request::old('username');
or in view:
{{ old('username') }}
You can redirect with old data like below with validation error
return redirect()->back()->withErrors($validator)->withInput();
<input type="text" name="username" value="{{ old('username') }}">
you must also define withInput() for the http route when redirecting to a page for example
return back()->withInput();
