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
|
<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
2
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
|
1
2
3
4
5
6
|
<?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
