该程序为整个系统的入口，含有两个全局参数：chat_hh,uname分别记录当前最大的发言序号和发言者名称 <? session_start(); session_register("chat_hh"); session_register("uname"); //取数据库最大编号 include("g_fun.php"); f_connectdb(); $query = "select max(lt_id) as rmaxid from lt_t_content"; $res = mysql_query($query, $dbh); $row = mysql_fetch_array($res); $f_chat_hh = $row["rmaxid"]; if (empty($f_chat_hh)) { $f_chat_hh = 0; } if ($f_chat_hh > 12 ) { $chat_hh=$f_chat_hh - 12; } else $chat_hh=$f_chat_hh; $un_len=strlen($name); $uname=$name; //增加在线人员信息 $query = "select count(*) as rcount from lt_t_online where lt_username = "".$name."""; $res = mysql_query($query, $dbh); $row = mysql_fetch_array($res); $lcount = $row["rcount"]; if ($lcount == 0) { $query = "insert into lt_t_online(lt_username,lt_lasttime) values("; $query .= """.$name."",now())"; $res = mysql_query($query, $dbh); } $query = "update lt_t_online set lt_lasttime = now(),lt_state = "0" "; $query .= " where lt_username = "".$name."""; $res = mysql_query($query, $dbh); ?> <html> <head> <title>PHP无刷新感聊天室</title> <meta http-equiv="Content-Type" content="text/html; charset=gb2312"> <script Language=JavaScript> function wu(){ var un="<?echo $name;?>"; this.f2.document.fyq.username.value=un; this.f2.document.fyq.username.size=<?echo $un_len;?>; } </script> </head> <frameset cols="*,140" border=1 frameborder=1 framespacing=> <frameset rows="0,*,70,0" border="1" framespacing="0" frameborder="yes"> <frame src="http://www.zzchn.com/edu/20070912/about:blank" name="tforlt4"> <frame src="http://www.zzchn.com/edu/20070912/about:blank" name="f1" marginheight="3" marginwidth="5"> <frame src="http://www.zzchn.com/edu/20070912/ltsayno.php" name="f2"> <frame src="http://www.zzchn.com/edu/20070912/about:blank" name="bforlt3"> </frameset> <frameset rows="*,150" border=1 frameborder=1 framespacing=0> <frame src="http://www.zzchn.com/edu/20070912/ltonline.php" name="f3" marginwidth=0 scrolling="auto"> <frame src="http://www.zzchn.com/edu/20070912/about:blank" name="f4" marginwidth=0> </frameset> </frameset> <noframes> <body bgcolor="#FFFFFF"> </body></noframes> </html> 源代码网供稿. |
