其实一直想把这个mod写完只是碍于学习和前段时间考研，一直没有时间。现在考研结束了又要忙着找实习单位，所以还来不及写完全部代码，不过基本功能大都实现了。所以现在应网友要求先把这个bata版贴出来，由于我的pa的模板和CSS改动较大，要花一定时间整理，所以模板这次没有贴出来，有兴趣的朋友可以自己试一试。
声明：
1.我是学经济的，不是学计算机的，自学php是出于兴趣爱好，所以代码如果写的不好请大家见谅。 php学习之家
2其次代码很容易看懂。
功能：实现了留言簿最基本的功能（回复功能未完工）：发表留言、查看留言、验证码（因为留言簿被攻击过，所以被迫加上）、登录后用户信息自动填写，管理员登录后出现删除链接。
准备条件：添加验证码mod，详情请见http://www.21ds.net/forum/5366.html php学习之家
在数据库添加一个表，Mysql代码如下。表的前缀pa_根据需要改 本文来自 www.444p.com
id int(10) unsigned NOT NULL auto_increment,
username varchar(30) NOT NULL default '',
icontype tinyint(2) unsigned NOT NULL default '0',
homepage varchar(100) default NULL,
qq int(16) default NULL,
email varchar(100) default NULL,
subject varchar(50) NOT NULL default '',
memo text NOT NULL,
date int(10) unsigned NOT NULL default '0',
visible tinyint(1) unsigned NOT NULL default '1',
reply text,
replydate int(10) unsigned default NULL,
replyvisible tinyint(1) unsigned NOT NULL default '1',
KEY id (id)
)
把guestbook.php上传到pa的根目录，如果你有兴趣可以按照guestbook.php中的模板和变量接口自己添加模板。
