权限管理系统,它主要是为了给不同的用户设定不同的权限,从而实现不同权限的用户登录之后使用的功能不一样。
首先先看下数据库
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。
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> <p><select id="user"> <? "./DBDA.class.php" = = "select * from users" = ->query(,0( "<option value='{[0]}'>{[2]}</option>"?> </select> </p> <br /> <p><? = "select * from roles" = ->query(,0( "<input type='checkbox' class='ck' value='{[0]}'>{[1]}"?> </p> <br /> <input type="button" value="确认" id="btn"/> </body> <script>"#user").change("#btn").click( uid = $("#user"). ck = $(".ck" role = ""; (i=0;i<ck.length;i++ v = ck.eq(i).(ck.eq(i).prop("checked"+= ck.eq(i).val()+"|".:"POST",:"RBbtnchuli.php",:{uid:uid,role:role},:"TEXT",:"修改成功!" uid = $("#user")..:"RBchuli.php",:{uid:uid},:"POST",:"TEXT",: role = data.("|" ck = $(".ck".prop("checked",(i=0;i<ck.length;i++ v = ck.eq(i).(role.indexOf(v)>=0.eq(i).prop("checked",</script> </html>
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
<?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); }
效果如图:
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="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> <p class="quanju"> <p class="form-group yangshi1"> <label for="firstname" class="col-sm-2 control-label">用户名:</label> <p class="col-sm-10"> <input type="text" class="form-control name" name="uid" placeholder="请输入用户名"> </p> </p> <p class="form-group yangshi2"> <label for="lastname" class="col-sm-2 control-label">密码:</label> <p class="col-sm-10"> <input type="text" class="form-control pwd" name="pwd" placeholder="请输入密码"> </p> </p> <p class="form-group"> <p class="col-sm-offset-2 col-sm-10"> <p class="checkbox"> <label> <input type="checkbox"> 保存密码 </label> <label> <input type="checkbox"> 下次自动登录 </label> </p> </p> </p> <p class="form-group"> <p class="col-sm-offset-2 col-sm-10"> <button type="submit" class="btn btn-warning" value="登录" onclick="return login()" > 登录 </button> </p> </p> </p> </form> </body> </html>
4.登录页面的处理页面RBloginchuli.php
<?phpsession_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"] = $uid; header("location:RBmain.php"); } else { echo "<script>alert('用户名或密码有误!')</script>"; }
5.最后做用户的主页面RBmain.php8b05045a5be5764f313ed5b9168a17e6
<html> <head> <meta charset="UTF-8"> <title>权限主页面</title> </head> <body> <?php session_start(); if(empty($_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 "<p class='menu'> { $v[1] } </p>"; } ?> </body> </html>
