php-人员权限管理(RBAC)

权限管理可以想做vip的功能,普通用户和vip用户的功能是不一样的,大致会用到五张表:用户表、角色表、功能表,还有他们之间互相关联的表:用户与角色表、角色与功能表

我用到的五张表如下:

                 

            

一.首先写的是管理员页面

1.用下拉列表显示用户名

<div>
	<select id="user">
    <?php
	require"../DBDA.class.php";
	$db = new DBDA();
	$sql = "select * from users";
	$arr = $db->query($sql,1);
	foreach($arr as $v)
	{
		echo"<option value='{$v[0]}'>{$v[2]}</option>";
	}
	?>
    </select>
</div>

 

2.因为上面已经造了新对象,所以在显示角色名时直接从SQL语句开始写

<div>请选择角色:
	<?php
	$sql = "select * from juese";
	$arr = $db->query($sql,1);
	foreach($arr as $v)
	{
		echo "<input type='checkbox' class='ck' value='{$v[0]}'/>{$v[1]}";
	}
	?>
</div>
<br/>

 

3.为了修改权限加一个确认保存按钮

<input type="button" value="保存" id="baocun" />

 

4.这样,再考虑怎么让数据库中用户本有的角色显示出来,那就是要用到下拉列表和复选框的值了

可以把它写入方法里,然后调用这个方法

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

 5.各项值的处理页面

<?php
require"../DBDA.class.php";
$db = new DBDA();
$uid = $_POST["uid"];
$sql = "select jueseid from userinjuese where userid='{$uid}'";
echo $db->strquery($sql);

效果如下:

6.最后就是保存修改后的值了,可以直接用全部删除在重新写入的方法来进行值的选择;对保存按钮添加单击事件

Xuan();

$("#user").change(function(){
		Xuan();
	})
$("#baocun").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 = str + ck.eq(i).val()+",";
			}
		}
	
	str = str.substr(0,str.length-1);
	
	$.ajax({
			url:"add.php",
			data:{uid:uid,js:str},
			type:"POST",
			dataType:"TEXT",
			success: function(data){
					alert("保存成功!");
				}
		})
	})

 7.保存的处理页面

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

//清空原有角色
$sql = "delete from userinjuese where userid='{$uid}'";
$db->query($sql);

//添加选中的角色
$ajs = explode(",",$js);

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

 效果如下:

 

下面代码用来copy用,注意AJAX需要引用Jquery

1.guanli.php

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>无标题文档</title>
<script src="../jquery-3.2.0.min.js"></script>
</head>

<body>
<h1>用户角色对应</h1>
<div>
	<select id="user">
    <?php
	require"../DBDA.class.php";
	$db = new DBDA();
	$sql = "select * from users";
	$arr = $db->query($sql,1);
	foreach($arr as $v)
	{
		echo"<option value='{$v[0]}'>{$v[2]}</option>";
	}
	?>
    </select>
</div>
<br/>
<div>请选择角色:
	<?php
	$sql = "select * from juese";
	$arr = $db->query($sql,1);
	foreach($arr as $v)
	{
		echo "<input type='checkbox' class='ck' value='{$v[0]}'/>{$v[1]}";
	}
	?>
</div>
<br/>
<input type="button" value="保存" id="baocun" />

</body>
<script type="text/javascript">

Xuan();

$("#user").change(function(){
		Xuan();
	})
$("#baocun").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 = str + ck.eq(i).val()+",";
			}
		}
	
	str = str.substr(0,str.length-1);
	
	$.ajax({
			url:"add.php",
			data:{uid:uid,js:str},
			type:"POST",
			dataType:"TEXT",
			success: function(data){
					alert("保存成功!");
				}
		})
	})
	
function Xuan()
{
	var uid = $("#user").val();
	$.ajax({
			url:"chuli.php",
			data:{uid:uid},
			type:"POST",
			dataType:"TEXT",
			success: function(data){
					var js = data.trim().split("|");
					var ck = $(".ck");
					ck.prop("checked",false);
					for(var i=0;i<ck.length;i++)
					{
						var v = ck.eq(i).val();
						if(js.indexOf(v)>=0)
						{
							ck.eq(i).prop("checked",true);
						}
					}
				}
			
		})
}
</script>
</html>

 2.chuli.php

<?php
require"../DBDA.class.php";
$db = new DBDA();
$uid = $_POST["uid"];
$sql = "select jueseid from userinjuese where userid='{$uid}'";
echo $db->strquery($sql);

 3.保存的处理页面 add.php

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

//清空原有角色
$sql = "delete from userinjuese where userid='{$uid}'";
$db->query($sql);

//添加选中的角色
$ajs = explode(",",$js);

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

 

二.完成管理员页面后,下面就是登录页面

1.登录基本页面 login.php

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>无标题文档</title>
</head>

<body>
<h1>登录界面</h1>
<form action="dlchuli.php" method="post">
<div>用户名:<input type="text" name="uid" /></div>
<div>密码:   <input type="password" name="pwd" /></div>
<input type="submit" value="登录" />
</form>
</body>
</html>

 2.登录处理的页面 dlchuli.php

<?php
session_start();


require "../DBDA.class.php";
$db = new DBDA();
$uid = $_POST["uid"];
$pwd = $_POST["pwd"];
$sql = "select pwd from users where uid='{$uid}'";
$mm = $db->strquery($sql);
if($mm==$pwd && !empty($pwd))
{
	$_SESSION["uid"] = $uid;
	header("location:main.php");
}
else
{
	echo"输入的用户名或密码有误!";
}

 

3.主页面 main.php

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>无标题文档</title>
<style type="text/css">
.list{ width:100px; 
	   height:35px; 
	   border:1px solid #36F; 
	   margin:0px 2px 0px 2px; 
           text-align:center; 
	   vertical-align:middle; 
	   line-height:35px;}
</style>
</head>

<body>
<h1>主页面</h1>
<?php
session_start();
$uid ="";
if(empty($_SESSION["uid"]))//判断session是否为空
{
	header("location:login.php");//空的话就返回登录页面
	exit;
}

$uid = $_SESSION["uid"];

require"../DBDA.class.php";
$db = new DBDA();
$sql = "select * from rules where code in(select distinct ruleid from juesewithrules where jueseid in(select jueseid from userinjuese where userid='{$uid}'))";

$arr = $db->query($sql,1);
foreach($arr as $v)
{
	echo "<div code='{$v[0]}' class='list'>{$v[1]}</div>";
}

?>
</body>
</html>
