一个模仿oso的论坛程序（之一）

时间：2007-02-17 来源：PHP爱好者

我经常使用oso的论坛，个人感觉挺好的，因此模仿oso的界面编了一个程序，与大家共享。
程序由三部分组成，即显示主题信息，显示论坛信息，增加论坛信息，主题与论坛内容采用主从表关系。
表结构如下：
drop table fr_t_forumtitle;
create table fr_t_forumtitle(
id         integer,
state      varchar(1),
readcount  integer,
replycount integer,
title      varchar(100),
createman  varchar(20),
replyman   varchar(20),
replytime  datetime);

drop table fr_t_forumcontent;
create table fr_t_forumcontent(
id          integer,
replyman    varchar(20),
replytime   datetime,
replyemail  varchar(100),
replyhttp   varchar(100),
replyface   smallint,
content     text);

drop table fr_t_parameter;
create table fr_t_parameter(
code    varchar(10),
name    varchar(40),
content varchar(10));
insert into  fr_t_parameter(code,name,content) values('pageline','分页数','20'); /* 调整该参数可以修改每页行数 */
