无JS,完全php面向过程数据分页实现代码

代码如下:

<?php 
//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']) && $_GET['pageNow']<=$pageCount){ 
$pageNow = $_GET['pageNow']; 
}else{ 
header("Location: ../Error/error.php"); 
exit(); 
} 
//打印分页数据 
echo "<div style='margin-left:300px;margin-top:1px;'>"; 
echo "<table style='border:1px;border-style:solid;border-width:1px;border-color:green'>"; 
echo "<tr><th>id</th> <th>name</th> <th>age</th> <th>sex</th> <th>birthday</th> <th>编辑雇员</th> <th>删除雇员</th> </tr>"; 
$sqList = "select id,name,age,sex,birthday from employee limit ".($pageNow-1)*$pageSize.",".$pageSize; 
$res2 = mysql_query($sqList,$mysql); 
while (false!=($row=mysql_fetch_assoc($res2))){ 
echo "<tr><td>{$row['id']}</td> <td>{$row['name']}</td> <td>{$row['age']}</td> <td>{$row['sex']}</td> <td>{$row['birthday']}</td> <td><a href=#>编辑</a></td> <td><a href=#>删除</a></td></tr>"; 
} 
echo "</table>"; 
//表单控制显示页数 
echo "<form action='当前页'>"; 
//上一页按钮 
if($pageNow>1){ 
$pageUp = $pageNow-1; 
echo "<a href='?pageNow=".$pageUp."'>上一页</a> "; 
} 

//下一页按钮 
if($pageNow<$pageCount){ 
$pageDown = $pageNow+1; 
echo "<a href='?pageNow=".$pageDown."'>下一页</a> <br/>"; 
} 

//后退十页按钮 
if($pageNow-10>0){ 
echo "<a href='?pageNow=".($pageNow-10)."'><<<</a> "; 
} 


//向本页传递当前显示的页数,并显示第几页按钮 
for($i=1;$i<=$pageCount;$i++){ 

if($i>$pageNow-2 && $i<$pageNow+6){ 
if($i!=$pageNow){ 
echo "<a href='?pageNow=".$i."'>第".$i."页</a> "; 
} 
} 
} 

//前进十页 
if($pageNow+10<=$pageCount){ 
echo "<a href='?pageNow=".($pageNow+10)."'>>>></a> "; 
} 

//显示当前页与总页数 
echo "<br/>当前页".$pageNow."页/共".$pageCount."页"; 


//跳转页 
echo "跳转到:<input type='text' name='pageNow' id='pageNow' style='width:30px;height:20px'/>页<input type='submit' style='width:37px;height:20px;font-size:11px;' value='go'/>"; 
echo "</form>"; 
echo "</div>"; 
?>
