本篇文章主要介绍php中的权限管理,感兴趣的朋友了解下,希望可以帮到大家。
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
1
2
3
4
5
6
7
8
9
10
11
12
13
14
<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
2
3
4
5
6
7
8
9
10
11
<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.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

<?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

<?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);
}
效果如下:
下面代码用来copy用,注意ajax需要引用jquery
