title: Laravel request get all filled values
body: <p>I am checking each field in laravel request like:</p>
  
  <pre><code>if($request-&gt;filled('type'))
      $item-&gt;type = $request-&gt;get('type');
  </code></pre>
  
  <p>Like <code>$request-&gt;all()</code> gives all the inputs in an array, Can we get all the filled values only? </p>
