调用会员组代码$post[authortitle]，默认只在viewthread_node.htm中生效，单独使用在viewthread_node.htm中调用的是最后回帖作者所在用户组名。

如要在viewthread.htm中调用楼主所在用户组，需要写成

<!--{loop $postlist $post}--><!--{if $post['first']}-->$post[authortitle]<!--{/if}--><!--{/loop}-->

调用楼主头像：

<!--{avatar($_G[forum_thread][authorid],small)}-->

复制代码

调用楼主主题数：

<!--{eval $louzhuid = $_G[forum_thread][authorid]; $zhutishu = DB::result(DB::query("SELECT threads FROM ".DB::table('common_member_count')." WHERE uid = '$louzhuid'"));}-->$zhutishu

复制代码

调用楼主积分：

<!--{eval $louzhuid = $_G[forum_thread][authorid]; $jifenshu = DB::result(DB::query("SELECT credits FROM ".DB::table('common_member')." WHERE uid = '$louzhuid'"));}-->$jifenshu
