提升主题期限功能插件

修改地方：
1、source/include/post/post_newreply.php里增加发帖时时间判断
找到471行：
DB::query("UPDATE ".DB::table('forum_thread')." SET lastposter='$author', lastpost='$_G[timestamp]', replies=replies+1 WHERE tid='$_G[tid]'", 'UNBUFFERED');
改为：        
        $deadtime = DB::result_first("SELECT lastpost FROM ".DB::table('forum_thread')." WHERE tid='$_G[tid]'");
        if($_G[timestamp] < $deadtime){
      DB::query("UPDATE ".DB::table('forum_thread')." SET lastposter='$author', replies=replies+1 WHERE tid='$_G[tid]'", 'UNBUFFERED');
        }else{
         DB::query("UPDATE ".DB::table('forum_thread')." SET lastposter='$author', lastpost='$_G[timestamp]', replies=replies+1 WHERE tid='$_G[tid]'", 'UNBUFFERED');
        }
2、template/default/forum/topicadmin.htm里增加管理菜单中提升主题的期限功能
找到287行：
<li class="wide"><label><input type="radio" name="operations[]" class="pr" value="bump" checked="checked"/> {lang admin_bump}</label></li>
在下一行继续添加：
<li class="wide">
<table cellspacing="0" cellpadding="0" width="100%">
<tr>
<td>{lang expire}: </td>
<td>
<p class="hasd">
<input type="text" name="expirationbump" id="expirationbump" class="px" autocomplete="off" value="$expirationdump" tabindex="1" />
<a href="javascript:;" class="dpbtn">^</a>
</p>
</td>
</tr>
</table>
</li>
3、source/include/topicadmin/topicadmin_moderate.php里增加时间提交至数据库的功能
找到315行左右：
DB::query("UPDATE ".DB::table('forum_thread')." SET lastpost='$_G[timestamp]', moderated='1' WHERE tid IN ($moderatetids)");
DB::query("UPDATE ".DB::table('forum_forum')." SET lastpost='$thread[tid]\t$thread[subject]\t$_G[timestamp]\t$thread[lastposter]' WHERE fid='$_G[fid]'");
改为：
if(($expiration = checkexpiration($_G['gp_expirationbump'], $operation))!=''){
        DB::query("UPDATE ".DB::table('forum_thread')." SET lastpost='$expiration', moderated='1' WHERE tid IN ($moderatetids)");
        DB::query("UPDATE ".DB::table('forum_forum')." SET lastpost='$thread[tid]\t$thread[subject]\t$_G[timestamp]\t$thread[lastposter]' WHERE fid='$_G[fid]'");
                }else{
                 DB::query("UPDATE ".DB::table('forum_thread')." SET lastpost='$_G[timestamp]', moderated='1' WHERE tid IN ($moderatetids)");
        DB::query("UPDATE ".DB::table('forum_forum')." SET lastpost='$thread[tid]\t$thread[subject]\t$_G[timestamp]\t$thread[lastposter]' WHERE fid='$_G[fid]'");
                }找到710行左右：
if(!empty($expiration) && in_array($operation, array('recommend', 'stick', 'digest', 'highlight', 'close'))) {
改为：
if(!empty($expiration) && in_array($operation, array('recommend','bump', 'stick', 'digest', 'highlight', 'close'))) {

看起来挺复杂的

看贴回帖是一种美德
