title: How to get values of checkbox array in Laravel 5?
body: <p>I created checkboxes in form using javascript:</p>
  
  <pre><code>&lt;input type="checkbox" name="is_ok[]" /&gt;
  &lt;input type="checkbox" name="is_ok[]" /&gt;
  &lt;input type="checkbox" name="is_ok[]" /&gt;
  </code></pre>
  
  <p>When I check 1st and 3rd checkbox and submit the form, <code>Input::get("is_ok")</code> returns me:</p>
  
  <pre><code>['on', 'on']
  </code></pre>
  
  <p>Is there any way to get value as <code>['on', null, 'on']</code> or <code>['on', 'off', 'on']</code>?</p>
  
  <p>Thanks in advance.</p>
