下面小編就為大家帶來一篇php 人員權限管理(RBAC)實例(推薦)。小編覺得蠻不錯的,現在就分享給大家,也給大家做個參考。一起跟著小編過來看看吧
php-人員權限管理(RBAC)
權限管理可以想做vip的功能,普通使用者和vip使用者的功能是不一樣的,大致會用到五張表:使用者表、角色表、功能表,還有他們之間互相關聯的表:使用者與角色表、角色與功能表
我用到的五張表如下:
1.用下拉清單顯示
使用者名稱
<p>
<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>
</p>
2.因為上面已經造了新對象,所以在顯示角色名稱時直接從SQL語句開始寫
<p>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]}";
}
?>
</p>
<br/>
3.為了修改權限加上一個確認儲存按鈕
##
<input type="button" value="保存" id="baocun" />
4.這樣,再考慮怎麼讓資料庫中使用者本有的角色顯示出來,那就是要用到
下拉清單和複選框的值了可以把它寫入方法裡,然後呼叫這個方法
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.各項值的處理頁面
<?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.最後就是儲存修改後的值了,可以直接用全部刪除在重新寫入的方法來進行值的選擇;對儲存按鈕新增點選事件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!");
}
})
})
<?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);
}
#下面程式碼用來copy用,
注意AJAX需要引用Jquery
1.guanli.php
无标题文档 用户角色对应
<p> <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> </p>
<p>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]}"; } ?> </p> <br/> <input type="button" value="保存" id="baocun" />
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.已儲存的處理頁面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.完成管理員頁面後,以下就是登入頁面
1.登入基本頁面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">
<p>用户名:<input type="text" name="uid" /></p>
<p>密码: <input type="password" name="pwd" /></p>
<input type="submit" value="登录" />
</form>
</body>
</html>
2.登入處理的頁面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!";
}
