Как добавить новые поля при регистрации Improved AJAX Login & Register Joomla?

Модуль регистрации на сайте. Форма состоит из следующих обязательных полей:
Имя Логин
Пароль Повторить пароль
email повторите email
Хочу добавить новое поле Фамилия.
Есть файл php, который отвечает за внешний вид и форму. Вот часть кода:

...
	<form action="<?php echo JRoute::_('index.php?option=com_improved_ajax_login&task=register', true, $params->get('usesecure')) ?>" method="post" name="register" id="regForm">
    <div class="columnL">
      <label class="smallTxt" for="nameReg"><?php echo JText::_("COM_USERS_REGISTER_NAME_LABEL") ?> <span class="req">*</span></label>
			<input id="nameReg" class="loginTxt regTxt required" name="name" type="text" title="<?php echo JText::_("COM_USERS_REGISTER_NAME_DESC") ?>"
      /><div style="display:none"><?php echo JText::_("COM_USERS_REGISTER_NAME_MESSAGE") ?></div>
    </div>
    <div class="columnR">
      <label class="smallTxt" for="userReg"><?php echo JText::_("COM_USERS_REGISTER_USERNAME_LABEL") ?> <span class="req">*</span></label>
      <div class="waitAnim" style="margin:6px 7px; display:none">
      </div><input id="userReg" class="loginTxt regTxt required" name="username" type="text" title="<?php echo JText::_("COM_USERS_REGISTER_USERNAME_DESC") ?>"
      /><div style="display:none"><?php echo str_replace('< ', '&lt; ', JText::sprintf('JLIB_DATABASE_ERROR_VALID_AZ09', 2)) ?></div>
    </div>
    <div class="columnL">
      <label class="smallTxt" for="passReg"><?php echo JText::_("COM_USERS_REGISTER_PASSWORD1_LABEL") ?> <span class="req">*</span></label>
      <label class="smallTxt" for="passReg" id="passStrongness"></label>
      <input id="passReg" class="loginTxt regTxt required" name="passwd" type="password" title="<?php echo JText::_("COM_USERS_DESIRED_PASSWORD") ?>"
      autocomplete="off" /><div style="display:none"><?php echo JText::_("COM_USERS_REGISTER_PASSWORD2_MESSAGE") ?></div>
      <label id="strongFields" for="passReg">
        <i class="empty strongField"></i><i class="empty strongField"></i><i class="empty strongField"></i><i class="empty strongField"></i><i class="empty strongField"></i>
      </label>
    </div>
    <div class="columnR">
      <label class="smallTxt" for="pass2Reg"><?php echo JText::_("COM_USERS_REGISTER_PASSWORD2_LABEL") ?> <span class="req">*</span></label>
      <input id="pass2Reg" class="loginTxt regTxt required" name="passwd2" type="password" title="<?php echo JText::_("COM_USERS_REGISTER_PASSWORD2_DESC") ?>"
      autocomplete="off" /><div style="display:none"><?php echo JText::_('COM_USERS_REGISTER_PASSWORD1_MESSAGE') ?></div>
    </div>
    <div class="columnL">
      <label class="smallTxt" for="mailReg"><?php echo JText::_("COM_USERS_REGISTER_EMAIL1_LABEL") ?> <span class="req">*</span></label>
      <div class="waitAnim" style="margin:6px 7px; display:none">
      </div><input id="mailReg" class="loginTxt regTxt required" name="email" type="text" title="<?php echo JText::_("COM_USERS_REGISTER_EMAIL1_DESC") ?>"
      /><div style="display:none"><?php echo JText::_('COM_USERS_INVALID_EMAIL') ?></div>
    </div>
    <div class="columnR">
      <label class="smallTxt" for="mail2Reg"><?php echo JText::_("COM_USERS_REGISTER_EMAIL2_LABEL") ?> <span class="req">*</span></label>
      <div class="waitAnim" style="margin:6px 7px; display:none">
      </div><input id="mail2Reg" class="loginTxt regTxt required" name="email2" type="text" title="<?php echo JText::_("COM_USERS_REGISTER_EMAIL2_DESC") ?>"
      /><div style="display:none"><?php echo JText::_('COM_USERS_REGISTER_EMAIL2_MESSAGE') ?></div>
    </div>

    <button class="loginBtn submitBtn" id="submitReg"><span><span class="waitAnim"></span><?php echo JText::_('JREGISTER') ?></span></button>
    <?php endif ?>

В MySQL в таблице _users добавил новое поле secondName, добавил информацию в файл ru-RU.com_users.ini
и добавил вот такой кусок кода

<div class="columnL">
      <label class="smallTxt" for="nameReg2"><?php echo JText::_("COM_USERS_REGISTER_NAME_LABEL2") ?> <span class="">*</span></label>
			<input id="nameReg2" class="loginTxt regTxt required" name="secondName" type="text" title="<?php echo JText::_("COM_USERS_REGISTER_NAME_DESC2") ?>"
      /><div style="display:none"><?php echo JText::_("COM_USERS_REGISTER_NAME_MESSAGE2") ?></div>
    </div>

Теперь не могу разобраться с редактированием файла, который отвечает за обработку и занесение данных в базу.

<?php

  $username = JRequest::getString('value');
  $db->setQuery("SELECT id FROM #__users WHERE username LIKE '$username'"); .// проверка есть ли такой user 
  if ($db->loadRow()) die($v15? JText::sprintf('WARNNAMETRYAGAIN', JText::_('USERNAME')) : JText::_('COM_USERS_REGISTER_USERNAME_MESSAGE'));
  die('success');
} elseif ($check == 'email') {
  $email = $filter->clean( JRequest::getString('value') );
  $db->setQuery("SELECT id FROM #__users WHERE email LIKE '$email'");
  if ($db->loadRow()) die(JText::_($v15? 'WARNREG_EMAIL_INUSE' : 'COM_USERS_REGISTER_EMAIL1_MESSAGE'));

}

$json = array();

Куда вставить код для обработки поля Фамилия?
