discuz 帖子列表页调用封面图片代码

打开文件：source/module/forum/forum_forumdisplay.php找到如下代码if($thread['rushreply']) { $rushtids[$thread['tid']] = $thread['tid'];}复制代码在这段代码下面添加如下代码：

$threada= C::t('forum_attachment')->fetch_all_by_id('tid', $thread['tid'], 'aid');$threadaid = reset($threada);$threadpic = C::t('forum_attachment_n')->fetch_by_aid_uid($threadaid['tableid'], $threadaid['aid'], $thread['authorid']);$thread['pic'] = $threadpic['attachment'];

这样就可以在列表页模板中使用$thread['pic']$thread['pic']所调用的是“附件”不分格式，也就是说，有可能调用到.rar/.zip之类的附件，并不是专调图片，算是个弊端。
