duplicate existing entries and change names

i.e. $post['username'] = JRequest::getVar('username', '', 'post', 'username');
$post['address1'] = JRequest::getVar('address1', '', 'post', 'address1');
$post['state'] = JRequest::getVar('state', '', 'post', 'state');

i.e. var $email = null;
var $address1 = null;
var $state = null;
