<body>

<h1>用户与角色管理</h1>

<div>

请选择用户：

<select id="user">

<?PHP

include("../../fengzhuang/DBDA.class.PHP");

$db = new DBDA();

$sql = "select * from qx_user";

$arr = $db->Query($sql);

foreach($arr as $v)

{

echo "<option value='{$v[0]}'>{$v[2]}</option>";

}

?>

</select>

</div>

<br />

<div>

请选择角色：

<?PHP

$sjs = "select * from qx_juese";

$ajs = $db->Query($sjs);

foreach($ajs as $v)

{

echo "<input type='checkBox' value='{$v[0]}' class='ck' />{$v[1]} ";

}

?>

</div>

<br />

<input type="button" value="确定" id="btn" />

</body>

<script type="text/javascript">

$(document).ready(function(e) {

//选中默认角色

Xuan();

//当用户选中变化的时候，去选中相应角色

$("#user").change(function(){

Xuan();

})

//点击确定保存角色信息

$("#btn").click(function(){

var uid = $("#user").val();

var juese = "";

var ck = $(".ck");

for(var i=0;i<ck.length;i++)

if(ck.eq(i).prop("checked"))

juese += ck.eq(i).val()+"|";

juese = juese.substr(0,juese.length-1);

$.ajax({

url:"chuli.PHP",

data:{uid:uid,juese:juese,type:1},

type:"POST",

dataType:"TEXT",

success: function(data){

alert("保存成功！");

});

})

});

//选中默认角色

function Xuan()

var uid = $("#user").val();

$.ajax({

url:"chuli.PHP",type:0},

success: function(data){

var juese = data.trim().split("|");

var ck = $(".ck");

ck.prop("checked",false);

for(var i=0;i<ck.length;i++)

if(juese.indexOf(ck.eq(i).val())>=0)

ck.eq(i).prop("checked",true);

});

}

</script>

</html>

chuli.PHP

<?PHP

include("../../fengzhuang/DBDA.class.PHP");

$db = new DBDA();

$type = $_POST["type"];

switch($type)

{

case 0:

$uid = $_POST["uid"];

$sql = "select jueseid from qx_uij where useid='{$uid}'";

echo $db->StrQuery($sql);

break;

case 1:

$uid = $_POST["uid"];

$juese = $_POST["juese"];

$sdel = "delete from qx_uij where useid='{$uid}'";

$db->Query($sdel,0);

$arr = explode("|",$juese);

foreach($arr as $v)

{

echo $v;

$sql = "insert into qx_uij values('','{$uid}','{$v}')";

$db->Query($sql,0);

}

echo "OK";

break;

}

我可以选择给哪个用户设置权限，给他一个什么角色，可以是一个，也可以多个，点击确定就在数据库中赋予了该权限。

例如：马七本身有前台和市场2个角色

现在，删除前台，增加财务

那我们看看数据库添加了没有

马七那项已经改了,j003和j004就是市场和财务角色。

接下来做的是登录某个账号，查看自己的职能

login.PHP

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "">

<body>

<h1>登录页面</h1>

<form action="logincl.PHP" method="post">

<input type="text" name="uid" />

<input type="password" name="pwd" />

<input type="submit" value="登录" />

</form>

</body>

</html>

logincl.PHP

<?PHP

session_start();

include("../../fengzhuang/DBDA.class.PHP");

$db = new DBDA();

$uid = $_POST["uid"];

$pwd = $_POST["pwd"];

$sql="select pwd from qx_user where uid='{$uid}'";

$mm = $db->StrQuery($sql);

if($mm==$pwd && !empty($pwd))

$_SESSION["uid"]=$uid;

header("location:main.PHP");

main.PHP

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "">

<html xmlns=">

<head>

<body>

<h1>主页面</h1>

<?PHP

session_start();

include("../../fengzhuang/DBDA.class.PHP");

$db = new DBDA();

if(empty($_SESSION["uid"]))

header("location:login.PHP");

exit;

//登录者用户名

$uid = $_SESSION["uid"];

//根据用户名查角色

$sjs = "select jueseid from qx_uij where useid='{$uid}'";

$ajs = $db->Query($sjs);

//定义一个存放功能代号的数组

$arr = array();

//根据角色代号查功能代号

foreach($ajs as $vjs)

$jsid = $vjs[0]; //角色代号

$sgn = "select ruleid from qx_jwr where jueseid='{$jsid}'";

$strgn = $db->StrQuery($sgn);

$agn = explode("|",$strgn);

foreach($agn as $vgn)

array_push($arr,$vgn);

//去重，显示

$arr = array_unique($arr);

foreach($arr as $v)

$sql = "select * from qx_rules where code='{$v}'";

$attr = $db->Query($sql);

$attr[0][0]; $attr[0][1];

echo "<div code='{$attr[0][0]}'>{$attr[0][1]}</div>";

}

?>

</body>
