disucz代码分析

1.discuz/templates/default/viewthread_fastpost.htm :
表单中请求地址为action="post.php?action=reply&fid=$fid&tid=$tid&extra=$extra&replysubmit=yes&infloat=yes&handlekey=fastpost
看最后的handlekey=fastpost

2.discuz/post.php 引入了 bbs/include/newreply.inc.php
Php代码 
      
//file_put_contents(bbbb.txt,"viewthread.php?tid=$tid&pid=$pid&page=$page&extra=$extra#pid$pid");  
//viewthread.php?tid=1&pid=21&page=2&extra=page%3D1#pid21  
showmessage($replymessage, "viewthread.php?tid=$tid&pid=$pid&page=$page&extra=$extra#pid$pid"); 

  
 //file_put_contents(bbbb.txt,"viewthread.php?tid=$tid&pid=$pid&page=$page&extra=$extra#pid$pid");
 //viewthread.php?tid=1&pid=21&page=2&extra=page%3D1#pid21
 showmessage($replymessage, "viewthread.php?tid=$tid&pid=$pid&page=$page&extra=$extra#pid$pid");

3.discuz/include/global.func.php 中showmessage();
Php代码 
elseif($handlekey)   
{  
    $show_message = str_replace("", "", $show_message);  
    if($url_forward)   
    {  
        $show_message = "";  
    }   
    省略.....   
}    

 elseif($handlekey)
 {
  $show_message = str_replace("", "", $show_message);
  if($url_forward)
  {
   $show_message = "";
  }
  省略..... 
 } 

showmessage()最后
Php代码 
include template(showmessage); 

 include template(showmessage);

4.disucz/templates/default/showmessage.htm
Php代码 
{echo str_replace(array({lang return_search}), array({lang return_replace}), $show_message)}
