一、登录页面

css样式

             *{
			margin:0px auto;
			padding:0px;
			}
		#login{
			background-color:#0CF;
			width:30%;
			height:200px;
			margin-top:50px;
			border:5px double #060;
			}

			text-indent:10px;
			vertical-align:bottom;
			line-height:30px;
			}
		#pwd{
			background-color:#CFF;
			height:70px;
			}
		#sb{
			background-color:#060;
			width:200px;
			height:30px;
			color:#CFF;
			margin-top:3px;
			}

 布局

<body>
	<form method="post" action="dengluchuli.php">
    <div id="login">
        <div align="left" id="dl">登录页面</div><br>
        <div id="yhm" align="center">用户名：
        <input type="text" placeholder="请输入用户名" name="uid"></div><br>
        <div id="pwd" align="center">密   码：
        <input type="password" placeholder="请输入密码" name="pwd"></div>
        <div align="center"><input type="submit" value="登录" id="sb"></div>
    </div>
    </form>
</body>

 登录处理页面

<?php
session_start();
require_once "../DBDA.class.php";
$db = new DBDA();
$uid = $_POST["uid"];
$pwd = $_POST["pwd"];
$sql = "select pwd from users where uid = \'{$uid}\' ";
$mm = $db->strquery($sql);
var_dump($mm);
if(!empty($pwd) && $pwd = $mm){
	$_SESSION["uid"] = $uid;
	header("location:main.php");
}else{
	header("location:denglu.php");
}

 

二、主界面

<head>
<meta charset="utf-8">
<title>无标题文档</title>
<style type="text/css">
	*{
		margin:0px auto;
		padding:0px;
		}
	#wai{
		font-size:24px;
		color:#060;
		margin:60px;
		}
	#biao{
		width:400px;
		height:60px;
		border:#00F 1px inset;
		text-align:center;
		font-size:36px;
		font-weight:bold;
		background-color:#060;
		color:#CFF;
		}
	.lie{
		width:400px;
		border:#00F inset 1px;
		text-align:center;
		}		
</style>
</head>

<body>
<?php
	session_start();
	if(empty($_SESSION["uid"])){
		header("location:denglu.php");
		exit;
	}
?>
    <div id="wai">
    	<div id="biao">拥有权限</div>
<?php
	require_once "../DBDA.class.php";
	$db = new DBDA();
	$uid = $_SESSION["uid"];
	$sql = "select name from rules where code in(select distinct ruleid from juesewithrules where jueseid in(select jueseid from userinjuese where userid=\'{$uid}\'))";
	$arr = $db->query($sql);
	foreach($arr as $v){
		echo"<div class=\'lie\'>$v[0]</div>";
	}
?>
    </div>
</body>

 

三、管理界面

<!doctype html>
<html>
<head>
<meta charset="utf-8">
<title>无标题文档</title>
<script src="../jquery-1.11.2.min.js"></script>
	<style type="text/css">
		*{
			margin:0px auto;
			padding:0px;
			}
		#wai{
			margin-top:60px;
			}	
		#a{
			background-color:#060;
			color:#CFF;
			font-size:30px;
			text-align:center;
			}	
    	#a,#b,#c{
			border:#00F inset 1px;
			border-bottom-style:none;
			width:40%;
			height:36px;
			vertical-align:middle;
			line-height:36px;
			font-weight:bold;
			}	
		#d{
			border:#00F inset 1px;
			width:40%;
			height:30px;
			}
		#user{
			background-color:#060;
			color:#CFF;
			width:100px;
			height:30px;
			font-size:18px;
			}
		#btn{
			background-color:#060;
			color:#FFF;
			width:100px;
			height:30px;
			margin-left:220px;
			}				
    </style>
</head>

<body>
	<div id="wai">
    	<div id="a">权限管理</div>
        <div id="b">选择用户名:  <select id="user">
<?php
	require_once "../DBDA.class.php";
	$db = new DBDA();
	$sql = "select * from users";
	$arr = $db->query($sql);
	foreach($arr as $v){
		echo "<option value=\'{$v[0]}\'>{$v[2]}</option>";
	}
?>        
        </select>
        </div>
        <div id="c">选择权限：
<?php
	$sql = "select * from juese";
	$arr = $db->query($sql);
	foreach($arr as $v){
		echo "<input class=\'ck\' type=\'checkbox\' value=\'{$v[0]}\' /> {$v[1]}
		    ";
	};
?>        
        </div>
        <div id="d">
        	<input type="button" value="确定" id="btn">
        </div>
    </div>
</body>
<script type="text/javascript">
$(document).ready(function(e) {
    xuanZhong();
	
	$("#user").change(function(){
		xuanZhong();
	})
	
	$("#btn").click(function(){
		var uid = $("#user").val();
		var str = "";
		var ck = $(".ck");
		for(var i=0;i<ck.length;i++){
			if(ck.eq(i).prop("checked")){
				str += ck.eq(i).val()+"|";
			}
		}
		str = str.substr(0,str.length-1);
		
		$.ajax({
			url:"update.php",
			data:{uid:uid,juese:str},
			type:"POST",
			dataType:"TEXT",
			success: function(data){
				alert("修改成功！");
			}
		});
	})
});


function xuanZhong(){
	var uid = $("#user").val();
	$.ajax({
		url:"chuli.php",
		data:{uid:uid},
		type:"POST",
		dataType:"TEXT",
		success: function(data){
			var lie = data.split("|");
			var ck = $(".ck");
			ck.prop("checked",false);
			
			for(var i=0;i<ck.length;i++){
				var v = ck.eq(i).val();
				if(lie.indexOf(v)>=0){
					ck.eq(i).prop("checked",true);
				}
			}
			
		}
	});
}
</script>
</html>

 复选框默认选中处理页面

<?php
require_once "../DBDA.class.php";
$db = new DBDA();

$uid = $_POST["uid"];
$sql = "select jueseid from userinjuese where userid=\'{$uid}\'";
echo $db->strquery($sql);

 

修改处理页面

<?php
require_once "../DBDA.class.php";
$db = new DBDA();
$uid = $_POST["uid"];
$juese = $_POST["juese"];

$sql = "delete from userinjuese where userid=\'{$uid}\'";
$db->query($sql,1);

$arr = explode("|",$juese);

foreach($arr as $v){
	$sql = "insert into userinjuese values(0,\'{$uid}\',\'{$v}\')";
	$db->query($sql,1);
}

 

 DBDA.class.php

<?php
class DBDA{
	public $host="localhost"; //服务器地址
	public $uid="root"; //用户名
	public $pwd="123"; //密码
	public $dbname="crud"; //数据库名称
	
	/*
		执行一条SQL语句的方法
		@param sql 要执行的SQL语句
		@param type SQL语句的类型，0代表查询 1代表增删改
		@return 如果是查询语句返回二维数组，如果是增删改返回true或false
	*/
	public function query($sql,$type=0){
		$db = new mysqli($this->host,$this->uid,$this->pwd,$this->dbname);
		$result = $db->query($sql);
		if($type){
			return $result;
		}else{
			return $result->fetch_all();
		}
	}
	public function strquery($sql,$type=0){
		$db = new MySQLi($this->host,$this->uid,$this->pwd,$this->dbname);
		$result = $db->query($sql);
		if($type){
			return $result;
			}else{
				$arr = $result->fetch_all();
				$str = "";
				foreach($arr as $v){
					$str .= implode("^",$v)."|";
					}
				$str = substr($str,0,strlen($str)-1);
				return $str;
				}
		}
	//返回json数据的方法
	public function jsonquery($sql,$type=0){
		$db = new MySQLi($this->host,$this->uid,$this->pwd,$this->dbname);
		$result = $db->query($sql);
		if($type){
			return $result;
		}else{
			$arr = $result->fetch_all(MYSQLI_ASSOC);//关联数组
			return json_encode($arr);//转换json
			//json_decode()分解json
		}
	}
}
