title: laravel's validator doesnt return input fields
body: <p>problems with returning inputs. after form submitted, if validator fails it doesnt return 'old' inputs. here's my controller</p>
  
  <pre><code>$validator = Validator::make($request-&gt;all(), [
          'user_rate' =&gt; 'required|integer|between:1,5',
          'user_comment' =&gt; 'required',
      ], [
          "user_rate.integer" =&gt; trans('errors.rate-required'),
          "user_rate.between" =&gt; trans('errors.rate-required'),
          "user_rate.required" =&gt; trans('errors.rate-required'),
          "user_comment.required" =&gt; trans('errors.com-required'),
  
      ]);
  
      if ($validator-&gt;fails()) {
          return redirect()-&gt;back()-&gt;withErrors($validator)-&gt;withInput($request-&gt;input());
          //return redirect()-&gt;back()-&gt;with(Input::all());
      }
  </code></pre>
