无JS,完全php面向过程数据分页实现代码_php技巧

//登陆页面设置的session,当session中存在name时
//session_start();
//$name = $_SESSION['name'];
//if (empty($name)){
// header("Location: error.php");
// exit();
//}
//面向过程, 数据分页显示
if(false!=($mysql = mysql_connect('本地mysql', 'mysql用户名', 'mysql密码'))){
mysql_query('set names utf8',$mysql); //设置数据库中的编码
mysql_select_db("数据库database",$mysql);
}else{
die("连接失败");
}


$pageSize = 10; //页面显示条数
$rowCount = 0; //数据总条数,从数据库获得

$sqlCount = 'select count(id) from employee';
$res1 = mysql_query($sqlCount,$mysql);

//取出数据条数
if(false!=($row=mysql_fetch_row($res1))){
$rowCount = $row[0];
}

//总页数,通过计算得到
$pageCount = 0;
$pageCount = ceil($rowCount/$pageSize);

//获取当前页
if(!isset($_GET['pageNow'])){ // 当 get/post都为空的时候赋默认值1
$pageNow = 1; //当前页数
}elseif(false!=is_numeric($_GET['pageNow']) && $_GET['pageNow']$pageNow = $_GET['pageNow'];
}else{
header("Location: ../Error/error.php");
exit();
}
//打印分页数据
echo "

";
echo "";
echo "";
$sqList = "select id,name,age,sex,birthday from employee limit ".($pageNow-1)*$pageSize.",".$pageSize;
$res2 = mysql_query($sqList,$mysql);
while (false!=($row=mysql_fetch_assoc($res2))){
echo "";
}
echo "

id	name	age	sex	birthday	编辑雇员	删除雇员
{$row['id']}	{$row['name']}	{$row['age']}	{$row['sex']}	{$row['birthday']}	编辑	删除

//表单控制显示页数

//上一页按钮
if($pageNow>1){

//下一页按钮

//后退十页按钮
if($pageNow-10>0){

//向本页传递当前显示的页数,并显示第几页按钮

//前进十页

//显示当前页与总页数
