这段代码在那个模版文件里的?

不建议在模版文件中执行查询
打开后台文件\source\module\forum\forum_forumdisplay.php

//搜索foreach($threadlist as $thread) {//在其上面添加foreach($threadlist as $v){	$tids[]=$v['tid'];}$strtids=join(',',$tids);$msginfos=DB::fetch_all("SELECT tid,message FROM %t WHERE tid IN($strtids)",array('forum_post'));if(!function_exists('messagecutstr')){	require_once libfile('function/post');}foreach($msginfos as $v){	$cutmsginfos[$v['tid']]=messagecutstr($v['message'],200);}//在其下面添加$thread['cutmsg']=$cutmsginfos[$thread['tid']];
Copy after login

前台用$thread['cutmsg']就可以获取
打开模版文件\template\default\forum\forumdisplay_list.htm
<!--230行左右,</tbody>上面添加--><tr>									<td colspan="6">$thread['cutmsg']</td>								</tr>
Copy after login


样子如上图所示,样式自己调


不建议在模版文件中执行查询
打开后台文件\source\module\forum\forum_forumdisplay.php
