joomla1.7用户注册定制问题

->我正在尝试新的用户注册自定义。

->为此，我通过从控制器调用函数来创建窗体和隐藏变量。

->在控制器保存函数中，我写了这段代码，但有些内部函数在1.7中不起作用，所以在这里产生了问题。

    function register_save()
{
    global $mainframe;
    $db =& JFactory::getDBO();
    // Check for request forgeries
    JRequest::checkToken() or jexit( 'Invalid Token' );
    //clean request
    $post = JRequest::get( 'post' );
    $post['username']   = JRequest::getVar('username', '', 'post', 'username');
    $post['password']   = JRequest::getVar('password', '', 'post', 'string', JREQUEST_ALLOWRAW);
    $post['password2']  = JRequest::getVar('password2', '', 'post', 'string', JREQUEST_ALLOWRAW);
    // get the redirect
    $return = JURI::base();
    // do a password safety check
    if(strlen($post['password']) || strlen($post['password2'])) { // so that "0" can be used as password e.g.
        if($post['password'] != $post['password2']) {
            $msg    = JText::_('PASSWORD NOT MATCH');
            // something is wrong. we are redirecting back to edit form.
            // TODO: HTTP_REFERER should be replaced with a base64 encoded form field in a later release
            $return = str_replace(array('"', '<', '>', "'"), '', @$_SERVER['HTTP_REFERER']);
            if (empty($return) || !JURI::isInternal($return)) {
                $return = JURI::base();
