How to modify the form objects used by ZfcUser

Task

Modify the form objects used by ZfcUser for registration and/or login.

Solution

You can accomplish this by hooking into the init event of the form you wish to modify. The simplest way to do this is pull the shared event manager and attach a listener.

<?php
public function onBootstrap($e)
{
    $events = $e->getApplication()->getEventManager()->getSharedManager();
    $events->attach('ZfcUser\Form\Register','init', function($e) {
        $form = $e->getTarget();
        // Do what you please with the form instance ($form)
    });
    $events->attach('ZfcUser\Form\RegisterFilter','init', function($e) {
        $filter = $e->getTarget();
        // Do what you please with the filter instance ($filter)
    });
}
