Product display of PHP development corporate website tutorial (2)
In the previous course, we have completed the paging effect of news
So we can copy the paging code in the previous section and then change the table name
The code is as follows :
<?php
require_once('conn.php'); //连接数据库
$page=isset($_GET['page']) ?$_GET['page'] :1 ;//接收页码
$page=!empty($page) ? $page :1;
$table_name="product";//查取表名设置
$perpage=4;//每页显示的数据个数
//最大页数和总记录数
$total_sql="SELECT count(*) from $table_name";
$total_result =mysql_query($total_sql);
$total_row=mysql_fetch_row($total_result);
$total = $total_row[0];//获取最大页码数
$total_page = ceil($total/$perpage);//向上整数
//临界点
$page=$page>$total_page ? $total_page:$page;//当下一页数大于最大页数时的情况
//分页设置初始化
$start=($page-1)*$perpage;
$sql = "SELECT * from product order by id desc limit $start,$perpage";
$info = mysql_query($sql);
//$sql = "select * from product order by id desc"; //查询user表中的数据
//$info = mysql_query($sql);
?>
