前一句是 threadids[threadindex] = $thread[‘tid’];

//內容摘要
         include_once libfile('function/post');
        include_once libfile('function/attachment');
        $thread['post'] = C::t('forum_post')->fetch_all_by_tid_position($thread
 
['posttableid'],$thread['tid'],1);
        $thread['post'] = array_shift($thread['post']);
        $thread['preview'] = messagecutstr($thread['post']['message'], 200);
        $attachments = C::t('forum_attachment_n')->fetch_all_by_id('tid:'.$thread['post']['tid'], 'pid', $thread['post']['pid']);
        $attachs
 
 = $imgattachs = array();
        foreach(C::t('forum_attachment')->fetch_all_by_id('pid', $thread['post']['pid'], 'aid') as $attach) {
                $attach = array_merge($attach, $attachments[$attach['aid']]);
                $attach['filenametitle'] = $attach['filename'];
                $attach
 
['ext'] = fileext($attach['filename']);
                getattach_row($attach, $attachs, $imgattachs);
        }
        $thread['attachments'] = $imgattachs;
        //內容摘要END

模板呼叫程式碼：
$thread[‘preview’]

後一句是 G[′forumthreadlist′][threadindex] = $thread;
