本文详细介绍本人最近在公司做的一个PHP留言板(PHP在线咨询留言系统)。
该模块是公司CMS系统中的一部分。
主要功能:
留言,回复,注册,管理。
技术细节:
1.注册与登录页面无刷新(AJAX)验证;
2.一条留言下可显示多条回复(一个原创的算法);
3.留言分页显示;4.留言管理(删除);
5.页面布局(HTML+DIV+CSS);
6.PHP操作MySQL数据库。
要使用此留言板,必须先创建数据库,而且MySQL账号设置为root,密码为root(或者自行修改多个php文件中默认的账号和密码)。数据库弄好之后,把“留言板-zollty”文件夹放到网站目录下,访问http://localhost/mb-zollty/index.php即可。
为方便大家使用,下面给出一个数据库备份文件guestbook.txt,你只需要恢复该数据库即可,恢复方式:
【在DOS下,输入: mysql -u用户名 -p密码 guestbook <F:\guestbook.txt(备份文件所在位置)】
guestbook.txt内容如下:

也可以自行创建该数据库,MySQL下创建数据库的命令如下:
创建数据库:
create database guestbook default character set utf8 collate utf8_general_ci;
创建表:
guest——存储用户信息
post——存储留言
revert——存储回复信息
admin——管理员账号数据库
create table guest( id int(11) not null auto_increment comment'客户自增id', name varchar(16) not null comment'客户名称', email varchar(60) null comment'电子邮箱', qq varchar(11) null comment'QQ号码', primary key(id) )engine=Myisam;
create table post( id int(11) not null auto_increment comment'POST主键自增id', guest_id varchar(11) not null comment'发布人ID', post text not null comment'发布内容', post_time varchar(14) not null comment'发布时间', primary key(id) )engine=Myisam;
create table revert( id int(11) not null auto_increment comment'revert主键自增id', post_id varchar(11) not null comment'留言ID', revert text not null comment'回复内容', revert_time varchar(14) not null comment'回复时间', admin varchar(16) null comment'管理名称', primary key(id) )engine=Myisam;
create table admin( name varchar(16) not null comment'管理名称', pwd varchar(16) not null comment'管理员密码', primary key(name) )engine=Myisam;
外键关系是:guest.id = post.guest_id,post.id = revert.post_id,revert.admin=admin.name
