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 */
程序1:mainforum.php
include ("c:mydbheader.inc");
?>
当前位置:主页——论坛 |   | 论坛搜索 |   |
$dbh = mysql_connect('localhost:3306','root','');
mysql_select_db('test');
$res=mysql_query("SELECT content FROM fr_t_parameter where code = 'pageline'",$dbh);
$row=mysql_fetch_array($res);
global $pageline;
$pageline = $row["content"];
if (empty($pageline)) {
$res=mysql_query("insert into fr_t_parameter(code,name,content) values('pageline','分页数','20')",$dbh);
$row=mysql_fetch_array($res);
$pageline = 20;
}
$res=mysql_query("SELECT COUNT(*) AS rcnt FROM fr_t_forumtitle",$dbh);
$row=mysql_fetch_array($res);
$rcount = $row["rcnt"];
$res=mysql_query("SELECT COUNT(*) AS rcnt_con FROM fr_t_forumcontent",$dbh);
$row=mysql_fetch_array($res);
$rcon_count = $row["rcnt_con"];
print '
'; |
$pages=ceil($rcount / $pageline); //$pages变量现在包含所需的页数
if (empty($offset)) {
$offset=1;
$curline = 0;
} else
$curline = ($offset - 1) * $pageline;
//打印表头
print '
';
if ($offset 1) { //如果偏移量是0,不显示前一页的链接 $newoffset=$offset - 1; print "前一页"; } else { print "前一页"; print " "; } //计算总共需要的页数 $pages=ceil($rcount/$pageline); //$pages变量现在包含所需的页数 |
