php实现的后台表格分页功能示例

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：$countbr/>";
?>
table border="1">
  tr>
    td>用户编号/td>
    td>用户名/td>
    td>密码/td>
    td>邮箱/td>
    td>电话/td>
    td>操作/td>
  /tr>
?php
  for($i=0;$icount($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=?php if($start>=3)echo $start-3; else echo $start; ?>" rel="external nofollow" >上页/a>

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。
