本文实例讲述了PHP实现的后台表格分页功能。分享给大家供大家参考,具体如下:
PHP;">
user.PHP:
PHP;">
PHP
//用户管理
echo "用户管理
"; @$start = $_REQUEST['start']; if($start === null || $start === " "){ die("start required"); } require("init.PHP"); $sql = "SELECT * FROM xz_user LIMIT $start,$pagecount"; $sql1 = "SELECT uid FROM xz_user"; $result = MysqLi_query($conn,$sql); $result1 = MysqLi_query($conn,$sql1); if($result === false || $result1 === false) { echo "执行失败"; }else { //$rowcount = MysqLi_affected_rows($conn); $arr = MysqLi_fetch_all($result,1); $rowcount = count($arr); echo "查询到的结果行数:" . $rowcount . "
"; //if($rowcount > 0){ $arr1 = MysqLi_fetch_all($result1,1); $count = count($arr1); echo "总行数:$count
"; ?>用户编号用户名PHP
for($i=0;$i

delete.PHP:

PHP
//删除用户
echo "删除用户
"; @$uid = $_REQUEST['uid']; if($uid === null || $uid === " "){ //这里注意,是|| die("uid required"); } require('init.PHP'); $sql = "DELETE FROM xz_user WHERE uid='$uid'"; $sql1 = "UPDATE xz_user SET uid=uid-1 WHERE uid > '$uid'"; $result = MysqLi_query($conn,$sql); if($result === false){ echo "执行失败"; }else{ $count = MysqLi_affected_rows($conn); if($count > 0){ echo "用户删除成功"; $result1= MysqLi_query($conn,$sql1); if($result1 === false){ echo "重排序失败"; }else{ echo "重排序成功"; } if($uid % $pagecount == 0) Header("Location:user.PHP?start=$uid"); if($uid % $pagecount == 1){ $uid -= 1; Header("Location:user.PHP?start=$uid"); } if($uid % $pagecount == 2){ $uid -= 2; Header("Location:user.PHP?start=$uid"); } }else{ echo "要删除的用户不存在"; } } ?>
"; @$uid = $_REQUEST['uid']; if($uid === null || $uid === " "){ //这里注意,是|| die("uid required"); } require('init.PHP'); $sql = "DELETE FROM xz_user WHERE uid='$uid'"; $sql1 = "UPDATE xz_user SET uid=uid-1 WHERE uid > '$uid'"; $result = MysqLi_query($conn,$sql); if($result === false){ echo "执行失败"; }else{ $count = MysqLi_affected_rows($conn); if($count > 0){ echo "用户删除成功"; $result1= MysqLi_query($conn,$sql1); if($result1 === false){ echo "重排序失败"; }else{ echo "重排序成功"; } if($uid % $pagecount == 0) Header("Location:user.PHP?start=$uid"); if($uid % $pagecount == 1){ $uid -= 1; Header("Location:user.PHP?start=$uid"); } if($uid % $pagecount == 2){ $uid -= 2; Header("Location:user.PHP?start=$uid"); } }else{ echo "要删除的用户不存在"; } } ?>
注:
(1)用AJAX可以实现传值优化,提升性能,这里没有实现;
(2)下一页那边还没有一些bug,不能到最后一页停止,后续再实现吧。
