ช่วยด้วยค่ะ Zend Framework แสดงข้อมูลจากตารางหนึ่ง เลือก checkbox พอ submit แล้วให้ลงอีกตารางหนึ่ง

<?php
    public function signAction()
    {
        $request = $this->getRequest();
        $form    = new Application_Form_Guestbook();
        if ($this->getRequest()->isPost()) {

            if ($form->isValid($request->getPost())) {

                $comment = new Application_Model_Guestbook($form->getValues());

                $mapper  = new Application_Model_GuestbookMapper();

                $mapper->save($comment);

                return $this->_helper->redirector('index');

            }

        }
        $this->view->form = $form;
    }
?>

<?php
    public function signAction()
    {
        $request = $this->getRequest();

            if ($form->isValid($request->getPost())) {

$values = $form->getValues();
$values['cb1'] = $request->getParam('tb2_cb1'); //แก้ไข data
$values['cb2'] = $request->getParam('tbc_cb2'); //แก้ไข data

                $comment = new Application_Model_Guestbook($values);
