we tried to give our tables(users,messages) like this in two different abstract classes but it is not working. This is included in a file childconnect1.php ,is there any relation between the file name(childconnect1.php) and the class(Application_Model_childconnect1).

class Application_Model_childconnect1 extends Zend_Db_Table_Abstract { protected $_name = 'users';

public function loginvalidation($username,$pwd)
{


    $row = $this->fetchRow('UserName = \'' . $username . '\'and UserPW = \''. $pwd . '\'');
    if (!$row)
    {
        $msg="invalid";
        return $msg;
    }
    else
    {
        return $row->toArray();
    }

}

}

class Application_Model_childconnect2 extends Zend_Db_Table_Abstract {

   protected $_name = 'messages';

    public function replymessage($message)
    {
    $data=array(
        'MessageText'=>$message
          );
    $this->insert($data);
    }

}
