1.管理员页面RBAC.php
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>权限管理</title>
<script src="bootstrap/js/jquery-1.11.2.min.js"></script>
</head>
<body>
<h2>用户与角色管理</h2>
<div>
请选择用户：
<select id="user">
<?php
require_once "./DBDA.class.php";
db = new DBDA();
sql = "select * from users";
$arr = db-\>query(sql,0);
foreach($arr as v){
echo "\("#user").change(function(){
//当用户选中变化的时候，去选中相应角色
sel();
})
//点击确定保存角色信息
$("#btn").click(function(){
var uid = $("#user").val();
var ck = (".ck");
var role = "";//初始为空
for(i=0;i\
type:"POST",
url:"RBbtnchuli.php",
data:{uid:uid,role:role},
dataType:"TEXT",
success:function(data){
alert("修改成功!");
}
});
})
//选中默认角色的封装方法
function sel(){
var uid = ("#user").val();
.ajax({
url:"RBchuli.php",
data:{uid:uid},
type:"POST",
dataType:"TEXT",
success:function(data){
var role = data.split("|");
var ck = $(".ck");
ck.prop("checked",false);
for(i=0;i<ck.length;i++){
var v = ck.eq(i).val();
if(role.indexOf(v)>=0){
ck.eq(i).prop("checked",true);
}
}
}
});
}
</script>
</html>
总共有5张表，users,roles和roleswork 3张表与另外2张表形成"w"型的关系，也是比较常见的一种权限数据库的方式，首先先做权限的设定，也就是管理层给不同用户设定不同权限。
2.做管理员的处理页面RBchuli.php
<?php
$uid = _POST\["uid"\];
require_once "./DBDA.class.php";
db = new DBDA();
sql = "select rolesuid from users_roles where usersuid='{uid}'";
echo db-\>StrQuery(sql,0); 保存角色信息的处理页面RBbtnchuli.php
保存角色信息的处理页面RBbtnchuli.php
<?php
$uid = $_POST["uid"];
$role = $_POST["role"];//字符串
role = substr(role,0,strlen($role)-1);
$arr = explode("|", $role);
require_once "./DBDA.class.php";
$db = new DBDA();
//删除
sdel = "delete from users_roles where usersuid='{uid}'";
db-\>query(sdel);
//添加
foreach($arr as $v){
sql = "insert into users_roles values(0,'{uid}','{$v}')";
db-\>query(sql);
}
接下来做的是登录某个账号，查看自己的职能
3.用户登录页面RBlogin.php
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title></title>
<script src="bootstrap/js/jquery-1.11.2.min.js"></script>
<script src="bootstrap/js/bootstrap.min.js"></script>
<link href="bootstrap/css/bootstrap.min.css" rel="external nofollow" rel="stylesheet" type="text/css"/>
</head>
<style>
.title{
margin-left: 600px;
margin-top: 150px;
}
.quanju{
margin-left: 450px;
margin-top: -180px;
}
.name,.pwd{
max-width: 120px;
}
.yangshi1{
margin-top: 200px;
}
</style>
<body>
<form class="form-horizontal" role="form" action="RBloginchuli.php" method="post">
<h3 class="title">用户登录</h3>
<div class="quanju">
<div class="form-group yangshi1">
<label for="firstname" class="col-sm-2 control-label">用户名:</label>
<div class="col-sm-10">
<input type="text" class="form-control name" name="uid" placeholder="请输入用户名">
</div>
</div>
<div class="form-group yangshi2">
<label for="lastname" class="col-sm-2 control-label">密码:</label>
<div class="col-sm-10">
<input type="text" class="form-control pwd" name="pwd" placeholder="请输入密码">
</div>
</div>
<div class="form-group">
<div class="col-sm-offset-2 col-sm-10">
<div class="checkbox">
<label>
<input type="checkbox">
保存密码 </label>
<label>
<input type="checkbox">
下次自动登录 </label>
</div>
</div>
</div>
<div class="form-group">
<div class="col-sm-offset-2 col-sm-10">
<button type="submit" class="btn btn-warning" value="登录" οnclick="return login()" >
登录
</button>
</div>
</div>
</div>
</form>
</body>
</html>
4.登录页面的处理页面RBloginchuli.php
<?php
session_start();
$uid = _POST\["uid"\];
pwd = _POST\["pwd"\];
require_once "./DBDA.class.php";
db = new DBDA();
sql = "select pwd from users where uid='{uid}'";
$mm = db-\>StrQuery(sql,0);
if(!empty($pwd) && pwd==mm){
$_SESSION["uid"] = $uid;
header("location:RBmain.php");
}else{
echo "<script>alert('用户名或密码有误!')</script>";
}
5.最后做用户的主页面RBmain.php
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>权限主页面</title>
</head>
<body>
<?php
session_start();
if(empty(_SESSION\["uid"\])){
header("location:RBlogin.php");
exit;
}
uid = _SESSION\["uid"\];
require_once "./DBDA.class.php";
db = new DBDA();
//子查询
sql = "select \* from roleswork where code in (select \* from roles_roleswork where rolesuid in (select \* from users_roles where usersuid='{uid}'))";
$arr = db-\>query(sql,0);
foreach($arr as v){
echo "\
