如何显示bigcommerce中的评论总数？

Question

我要显示总审阅次数，但以下代码无效

    $config['sess_driver'] = 'files';
    $config['sess_cookie_name'] = 'ci_session';
    $config['sess_expiration'] = 0;
    $config['sess_save_path'] = NULL;
    $config['sess_match_ip'] = FALSE;
    $config['sess_time_to_update'] = 300;
    $config['sess_regenerate_destroy'] = TRUE;
    $config['sess_expire_on_close'] = TRUE;
