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 */
