PHP+MySQL实现输入页码跳转到指定页面功能示例

本文实例讲述了PHP+MySQL实现输入页码跳转到指定页面功能。分享给大家供大家参考，具体如下：

一、代码

conn.php：

?php
$id=mysql_connect("localhost","root","root")or dir('连接失败' . mysql_error());
if(mysql_select_db("db_database13",$id))
echo "";
else
echo ('连接失败' . mysql_error());
mysql_query("set names gb2312");
?>

index.php：

?php session_start();include("conn/conn.php"); if ($_GET['page']=="") {$_GET['page']=1;};?>
html>
head>
meta http-equiv="Content-Type" content="text/html; charset=gb2312" />
title>查询结果的分页显示/title>
style type="text/css">
!--
.STYLE1 {font-size: 12px}
.STYLE2 {font-size: 13px}
a:link {
 text-decoration: none;
}
a:visited {
 text-decoration: none;
}
a:hover {
 text-decoration: none;
}
a:active {
 text-decoration: none;
}
-->
/style>
/head>
script language="javascript">
 function chk(form){
 if(form.page.value=0||form.page.value>form.pages.value){
 alert("您输入的页码无效!!");
 form.page.focus();
 return(false);
 }
 return(true);
 }
/script>
