      $id = (int) $this->_request->getParam('id');
    //The incoming request
    $request = $this->getRequest();
    //initialize form
    $form = new Admin_Form_DownFooterTab();
    //instance of db
    $db = Zend_Db_Table::getDefaultAdapter();

    if ($this->getRequest()->isPost()) {
        if ($form->isValid($request->getPost())) {
            if (isset($id) && $id != "") {
                $gettag = $form->getValue('tag_id');
                $gettags = count($gettag);
                try {
                    //shift the orders to
                    $select = $db->select()->from(array('t' => 'tab'), array('t.id',
                                't.title',

                    $currentTab = $db->fetchRow($select);
