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

8
9
10
11
12

<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
|
1

3
4
5
6
7
8
9
10
11
|
<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
|
1
|
<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
|

|
<?phprequire"../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

<?phprequire "../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
