首先先看下資料庫
總共有5張表，users,roles和roleswork 3張表與另外2張表形成"w"型的關係，也是比較常見的一種許可權資料庫的方式，首先先做許可權的設定，也就是管理層給不同使用者設定不同許可權。
1.管理員頁面RBAC.php
<!DOCTYPE html><html> <head> <meta charset="UTF-8"> <title>許可權管理</title> <script src="bootstrap/js/jquery-1.11.2.min.js"></script> </head> <body> <h2>使用者與角色管理</h2> <div> 請選擇使用者： <select id="user"> <?php require_once "./DBDA.class.php"; $db = new DBDA(); $sql = "select * from users"; $arr = $db->query($sql,0); foreach($arr as $v){ echo "<option value='{$v[0]}'>{$v[2]}</option>"; } ?> </select> </div> <br /> <div> 請選擇角色： <?php $sql = "select * from roles"; $arr = $db->query($sql,0); foreach($arr as $v){ echo "<input type='checkbox' class='ck' value='{$v[0]}'>{$v[1]}"; } ?> </div> <br /> <input type="button" value="確認" id="btn"/> </body> <script> sel(); //選中預設角色 $("#user").change(function(){ //當使用者選中變化的時候，去選中相應角色 sel(); }) //點擊確定儲存角色資訊 $("#btn").click(function(){ var uid = $("#user").val(); var ck = $(".ck"); var role = "";//初始為空白 for(i=0;i<ck.length;i++){ var v = ck.eq(i).val(); if(ck.eq(i).prop("checked")){ role += ck.eq(i).val()+"|"; } } $.ajax({ type:"POST", url:"RBbtnchuli.php", data:{uid:uid,role:role}, dataType:"TEXT", success:function(data){ alert("修改成功!"); } }); }) //選中預設角色的封裝方法 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 = $(".ck"); ck.prop("checked",false); for(i=0;i<ck.length;i++){ var v = ck.eq(i).val(); if(role.indexOf(v)>=0){ ck.eq(i).prop("checked",true); } } } }); } </script></html>
2.做管理員的處理頁面RBchuli.php
<?php$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);
儲存角色資訊的處理頁面RBbtnchuli.php
<?php$uid = $_POST["uid"];$role = $_POST["role"];//字串$role = substr($role,0,strlen($role)-1);$arr = explode("|", $role);require_once "./DBDA.class.php";$db = new DBDA();//刪除$sdel = "delete from users_roles where usersuid='{$uid}'";$db->query($sdel);//添加foreach($arr as $v){$sql = "insert into users_roles values(0,'{$uid}','{$v}')";$db->query($sql);}
效果
接下來做的是登入某個帳號，查看自己的職能
3.使用者登入頁面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">使用者登入</h3> <p class="quanju"> <p class="form-group yangshi1"> <label for="firstname" class="col-sm-2 control-label">使用者名稱:</label> <p class="col-sm-10"> <input type="text" class="form-control name" name="uid" placeholder="請輸入使用者名稱"> </p> </p> <p class="form-group yangshi2"> <label for="lastname" class="col-sm-2 control-label">密碼:</label> <p class="col-sm-10"> <input type="text" class="form-control pwd" name="pwd" placeholder="請輸入密碼"> </p> </p> <p class="form-group"> <p class="col-sm-offset-2 col-sm-10"> <p class="checkbox"> <label> <input type="checkbox"> 儲存密碼 </label> <label> <input type="checkbox"> 下次自動登入 </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="登入" onclick="return login()" > 登入 </button> </p> </p> </p> </form> </body></html>
4.登入頁面的處理頁面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"] = $uid; header("location:RBmain.php");}else{ echo "<script>alert('使用者名稱或密碼有誤!')</script>";}
5.最後做使用者的首頁面RBmain.php
<!DOCTYPE html><html> <head> <meta charset="UTF-8"> <title>許可權首頁面</title> </head> <body> <?php session_start(); if(empty($_SESSION["uid"])){ header("location:RBlogin.php"); exit; } $uid = $_SESSION["uid"]; require_once "./DBDA.class.php"; $db = new DBDA(); //子查詢 $sql = "select * from roleswork where code in (select * from roles_roleswork where rolesuid in (select * from users_roles where usersuid='{$uid}'))"; $arr = $db->query($sql,0); foreach($arr as $v){ echo "<p class='menu'>{$v[1]}</p>"; } ?> </body></html>
