刚才那几节课程里面将功能几乎都实现了出来，公众平台营销咨询系统最后一部分就是分页的实现了，show_info.php这里修改下代码分页即可实现出来，代码如下所示：
<?php //链接数据库 $connect = mysql_connect('localhost','root','root'); mysql_select_db('wxdb',$connect); mysql_query('set names utf8'); //分页开工咯，先取个别名counts $sql = "select count(*) as counts from zx_info"; $res = mysql_query($sql); $row = mysql_fetch_assoc($res); //这里的$row_num是总的咨询条数 $row_num = $row['counts']; //我们规定每页显示5条记录 $page_size = 5; //计算总页数 $page_count = ceil($row_num/$page_size); //接收当前用户点击的是第几页 $page_num = $_GET['page_num']; //判断$page_num是否为空,如果是空的默认给他一个1 if(empty($page_num)){ $page_num = 1; } //计算从那条记录开始获取 $begin = ($page_num-1)*$page_size; $sql = "select * from zx_info order by id desc limit {$begin},{$page_size}"; $info_res = mysql_query($sql); ?> <!doctype html> <html> <head> <meta charset="utf-8"> <title>公众平台营销咨询系统</title> <meta name="viewport" content="width=device-width,height=device-height,inital-scale=1.0,maximum-scale=1.0,user-scalable=no;"> <meta name="apple-mobile-web-app-capable" content="yes"> <meta name="apple-mobile-web-app-status-bar-style" content="black"> <meta name="format-detection" content="telephone=no"> <link href="./jquery.mobile-1.0.min.css" rel="stylesheet" type="text/css"> <script src="./jquery-1.6.4.min.js" type="text/javascript"></script> <script src="./jquery.mobile-1.0.min.js" type="text/javascript"></script> </head> <body> <div data-role='page' id='page3'> <div data-role='header'> <h1>公众平台营销咨询系统</h1> </div> <div data-role='content'> <ul data-role='listview'> <?php $row = array(); while($row = mysql_fetch_assoc($info_res)){ ?> <li> <a href="/reply_view.php?id=<?php echo $row['id']; ?>"><?php echo $row['zx_info']; ?> <p class="ui-li-aside">回复咨询</p></a> </li> <?php } ?> </ul> </div> <!--分页的按钮开始--> <div data-role="controlgroup" data-type="horizontal"> <?php if($page_num!=1 && $page_num>1){ ?> <a href="/show_info.php?page_num=<?php echo $page_num-1; ?>" data-role="button">上一页</a> <?php } ?> <?php if($page_count > $page_num){ ?> <a href="/show_info.php?page_num=<?php echo $page_num+1; ?>" data-role="button">下一页</a> <?php } ?> </div> <!--分页的按钮结束--> </div> </body> </html>
