Extending ZfcUser with Zend Framework 2

Hi I am trying to write a user registration form using ZfcUser module for Zend Framwork 2 and would like some advice on best practices when adding more user fields. So far I have created my own module called "WbxUser" and as outlined in the modules wiki pages I have added a custom field called "userlastname" to ZfcUser's registration form by using the Event Manager in my modules bootstrap function like so. Code: ``` //WbxUser.Module.php namespace WbxUser; use Zend\Mvc\MvcEvent; class Module { public function onBootstrap(MvcEvent $e){ $events = $e->getApplication()->getEventManager()->getSharedManager(); $events->attach('ZfcUser\Form\Register','init', function($e) { $form = $e->getTarget(); $form->add(array( 'name' => 'userlastname', 'attributes' => array( 'type' => 'text', ), 'options' => array( 'label' => 'Last Name', ), )); // Do what you please with the form instance ($form) }); $events->attach('ZfcUser\Form\RegisterFilter','init', function($e) { $filter = $e->getTarget(); $filter->add(array( 'name' => 'userlastname', 'required' => true, 'filters' => array( array('name' => 'StripTags'), array('name' => 'StringTrim'), ), 'validators' => array( array( 'name' => 'StringLength', 'options' => array( 'min' => 3, 'max' => 255, ), ), ), )); }); } public function getConfig(){ return array(); } public function getAutoloaderConfig(){ return array(); } } ``` But after this I have got a bit lost on where/how to write the code to save the extra data that my new fields are gathering. Is this the event where I can fire off save routines for the additional fields https://github.com/ZF-Commons/ZfcUser/wiki/How-to-perform-a-custom-action-when-a-new-user-account-is-created Should I be writing my own WbxUser model that extends ZfcUser\Entity\User.php to add my new fields I am a bit of a ZF and MVC noob so would be very great-full for a nudge in the write direction.
