 <p>In your Form, you can override the doSave() method to do any manual interventions that you need to do that aren't completed by the form validation methods.</p> <p>For example: </p> <pre><code>public function doSave($con = null) { $employee = $this-&gt;getObject(); $values = $this-&gt;getValues(); // do your filter $this-&gt;values['name'] = strtolower($values['name']); parent::doSave($con); } </code></pre>
