原因：不少人比较习惯那种树型结构的帖子列表模式，可以对某贴回复，而不是话题。
优点：自动记录、识别用户所使用的显示模式；虽然修改了原有数据表的结构，但不影响原有帖子，而且也不需要对旧帖子进行任何加工，程序能自动将旧的都正常显示出来。
缺点：应该会有，正在测试中。
自评：从K.W.大哥那得到的启发。做起来并不算复杂，但恐怕很多玩惯UBB的朋友需要改变一下习惯，就是每次发言都要输入标题——当然，程序已经缺省地为他们加了。
范例：http://gogosoft.oso.com.cn/forum/showthread.php?threadid=54
步骤：建议在网络速度可以的情况下更新，否则在你更新过程中的访问者可能会出错。
一、文件篇
⒈打开 global.php ，查找“
if (isset($username)!=0 and $username!="" and isset($password)!=0) {
”，在前面加入“
// Hack tree
if (isset($showmethod)!=0 AND $showmethod!="") {
setcookie("bbshowmethod",$showmethod,mktime(0,0,0,0,0,2020),$cookiepath);
} else {
if (isset($bbshowmethod)!=0 AND $bbshowmethod!="") {
$showmethod=$bbshowmethod;
} else {
$showmethod="showthread";
}
}
// End hack tree
”，保存退出；
⒉打开 member.php ，查找“
setcookie("bbuserid","",mktime(0,0,0,0,0,1998),$cookiepath);
setcookie("bbpassword","",mktime(0,0,0,0,0,1998),$cookiepath);
”，在后面加入“
setcookie("bbshowmethod","",mktime(0,0,0,0,0,1998),$cookiepath);
”，保存退出；
⒊打开 newreply.php ，查找“
// check for subject and message
if ($message=="") {
echo standarderror($bbtitle,gettemplate("error_nosubject",0));
”，将中间一行替换为“
if ($message=="" or $title=="") {
”，查找“
$threadid=verifyid("thread",$threadid);
”，在前面加入“
// hack thread-flat
$parentpostid=$postid;
$threadinfo=$DB_site->query_first("SELECT thread.threadid,thread.title,thread.forumid,
thread.replycount,thread.open
FROM post
LEFT JOIN thread ON (thread.threadid = post.threadid)
WHERE postid=$parentpostid");
$threadid=$threadinfo[threadid];
// end hack thread-flat
”，查找“
$threadinfo=$DB_site->query_first("SELECT title,forumid,replycount,open FROM thread WHERE threadid=$threadid");
”，在此行前面加“//”屏蔽掉，查找“
$DB_site->query("INSERT INTO post (postid,threadid,title,username,userid,dateline,pagetext,allowsmilie,email,signature,ip
ddress,iconid,visible) VALUES (NULL,$threadid,'".addslashes($title)."','".addslashes($postusername)."',$userid,".time().",'".ad
slashes($message)."',$allowsmilie,$email,$signature,'$ipaddress',$iconid,$visible)");
”，替换为“
// hack thread-flat add /parentpostid and $postparentid/
$DB_site->query("INSERT INTO post (postid,threadid,title,username,userid,dateline,pagetext,allowsmilie,email,signature,ipaddress,iconid,visible,parentpostid) VALUES (NULL,$threadid,'".addslashes($title)."','".addslashes($postusername)."',$userid,".time().",'".addslashes($message)."',$allowsmilie,$email,$signature,'$ipaddress',$iconid,$visible,$parentpostid)");
”，查找“
if ($getthread[title]!="") {
$title="Re: $getthread[title]";
}
”，去掉判断，也就是替换为“
$title="Re: $getthread[title]";
”，查找“
eval("$message = "".gettemplate("quotereply")."";");
”，替换为“
// hack thread-flat
if ($quota=="yes") {
eval("$message = "".gettemplate("quotereply")."";");
}
// end hack thread-flat
”，查找“
if (!$thread=$DB_site->query_first("SELECT threadid FROM thread WHERE threadid=$threadid")) {
$idname="thread";
eval("echo standarderror($bbtitle,"".gettemplate("error_invalidid")."");");
exit;
}
”，在后面加入“
$post=$DB_site->query_first("SELECT postid,title FROM post WHERE threadid=$threadid ORDER BY dateline $postorder");
$postid=$post[postid];
$title="Re: $post[title]";
”，保存退出；
⒋打开 showthread.php ，查找“
$threadid = verifyid("thread",$threadid);
$threadinfo=$DB_site->query_first("SELECT title,forumid,open,lastpost,replycount+1 AS posts,views,visible FROM thread WHERE threadid=$threadid");
”，在前面加入“
// Hack tree
if (isset($threadid)==0 or $threadid==0 or $threadid=="") {
$thread=$DB_site->query_first("SELECT threadid FROM post WHERE postid=$postid");
$threadid=$thread[threadid];
}
if (isset($postid)==0 or $postid==0 or $postid=="") {
$post=$DB_site->query_first("SELECT postid FROM post WHERE threadid=$threadid ORDER BY dateline DESC");
$postid=$post[postid];
}
$currentpostid=$postid;
$post=$DB_site->query_first("SELECT postid FROM post WHERE threadid=$threadid ORDER BY dateline");
$parentpostid=$post[postid];
// End Hack tree
”，查找“
} else {
$usetemplate="showthread";
}
”，替换为“
} else {
$usetemplate=$showmethod;
}
”，查找“
if ($foruminfo[active]==0) {
echo standarderror($bbtitle,gettemplate("error_forumclosed",0));
exit;
}
”，开始标记，直至“
$counter=0;
”（第一个），连同后面的全部PHP代码剪切到新文件 sub_showthread.php 中（注意在文件头、尾加入PHP标记 <?PHP 和 ?>），并在后面加入“
include("sub_".$showmethod.".php");
”，顺便将以下内容粘贴为新文件 sub_treethread.php “

二、模板篇
⒈新增模板 treethread ，内容为“

</td></tr></table>
$footer
</body>
</html>
”。
⒉新增模板 treethreadbit ，内容为“
<tr bgcolor="$backcolor">
<td width="100%" valign="top" nowrap>
<smallfont>$treedeepspace $foldericon $posticon
<B>$postitlelink</b>
($postsize)
- $username,
$postdate $posttime
</td>
</tr>
”。
⒊编辑模板 showthread ，在适当位置加入树型目录的连接，例如查找“
$nextoldest $nextnewest
”，在前面紧加入“
<a href="showthread.php?showmethod=treethread&postid=$postid">树型目录</a> |
”，保存。
⒋编辑模板 postbit ，查找“
<A HREF="newreply.php?action=newreply&postid=$postid">
”，替换为“
<A HREF="newreply.php?action=newreply"a=yes&postid=$postid">
”，即为“引用回复”的连接增加一个参数 quota ，值为 yes ，并在此图片连接后加入回复连接“
<A HREF="newreply.php?action=newreply&postid=$postid"><IMG SRC="images/reply2.gif" BORDER=0 ALT="回复"></A>
”，顺便的，你得准备一个 reply2.gif 以连接回复帖子（而不是回复话题），准备一个 blank.gif 全透明的，排版用。保存。
⒌编辑模板 newrelpy ，查找“
<INPUT TYPE="HIDDEN" NAME="threadid" VALUE="$threadid">
”，替换为“
<INPUT TYPE="HIDDEN" NAME="postid" VALUE="$postid">
”，保存。
这里的模板都有一个 {tablebordercolor} 变量，作用请参考我在奥索发表的题为《vBulletin的使用心得----两则版面方面的改良》一文。
三、数据库篇（最好是第一步做）
使用 phpMyAdmin 或其它工具打开讨论区数据库，修改 post 表的结构，在数据库尾新增一字段：
字段 parentpostid
类型 int(10)
属性 UNSIGNED
Null 否
