这篇文章主要介绍了php实现的后台表格分页功能,涉及php针对数据库的连接、查询、删除、动态生成表格等相关操作技巧,需要的朋友可以参考下
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
- //init.php
- $conn = mysqli_connect('127.0.0.1','root','','xz',3306);
- $sql = "SET NAMES UTF8";
- mysqli_query($conn,$sql);
- $pagecount = 3;
- ?>
user.php:
- <?php
- //用户管理
- echo "用户管理<br/>";
- @$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:" . $rowcount . "<br/>";
- //if($rowcount > 0){
- $arr1 = mysqli_fetch_all($result1,1);
- $count = count($arr1);
- echo "总行数:$count<br/>";
- ?>
- <table border="1">
- <tr>
- <td>用户编号</td>
- <td>用户名</td>
- <td>密码</td>
- <td>邮箱</td>
- <td>电话</td>
- <td>操作</td>
- </tr>
- <?php
- for($i=0;$i<count($arr);$i++){
- $tmp = $arr[$i]['uid'];
- echo "
- <tr>
- <td>".$arr[$i]['uid']."</td>
- <td>".$arr[$i]['uname']."</td>
- <td>".$arr[$i]['upwd']."</td>
- <td>".$arr[$i]['email']."</td>
- <td>".$arr[$i]['phone']."</td>
- <td><a href='delete.php?uid=".$tmp."'>删除</a></td>
- </tr>
- ";
- }
- ?>
- </table>
- <?php
- }
- ?>
- <!-- 传值 AJAX可优化 -->
- <a href="user.php?start=0" rel="external nofollow" >首页</a>
- <a href="user.php?start=<?php if($start>=3)echo $start-3; else echo $start; ?>" rel="external nofollow" >上页</a>
- <a href="user.php?start=3" rel="external nofollow" >2</a>
- <a href="user.php?start=6" rel="external nofollow" >3</a>
- <a href="user.php?start=9" rel="external nofollow" >4</a>
- <a href="user.php?start=12" rel="external nofollow" >5</a>
- <a href="user.php?start=15" rel="external nofollow" >6</a>
- <a href="user.php?start=<?php echo $start+3; ?>" rel="external nofollow" >下页</a>
- <a href="user.php?start=<?php if($count%3==1)echo $count-1; elseif($count%3==2) echo $count-2; elseif($count%3==0) echo $count-3; ?>" rel="external nofollow" >尾页</a>
- <span>第<?php echo $start/$pagecount+1 ?>页|共<?php $tmp=$count/$pagecount; $tmp1=(int)($count/$pagecount); if($tmp>$tmp1) echo $tmp1+1; else echo $tmp1; ?>页</span>
delete.php:
- <?php
- //删除用户
- echo "删除用户<br/>";
- @$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。
