权限管理

根据登录用户名显示不同功能：

<?php
session_start();
include("../DBDA.class.php");
$db = new DBDA();

if(empty($_SESSION["uid"]))
{
    header("location:login.php");
    exit;
}

$uid = $_SESSION["uid"];

?>
<body>

<div style="width:100%; height:35px;">
<?php

//根据用户名查角色代号
$sjuese="select jueseid from userinjuese where userid='{$uid}'";
$ajuese = $db->Query($sjuese);

//根据角色代号查功能
$attr = array();
foreach($ajuese as $v)
{
    $sgn = "select ruleid from juesewithrules where jueseid='{$v[0]}'";
    $agn = $db->Query($sgn);
    $attr = array_merge($attr,$agn);  //array_mergy()函数将一个或多个数组合并为一个；
}
//对功能代号数组进行去重

$attr = array_unique($attr,SORT_REGULAR);



foreach($attr as $v)
{
    $sname = "select name from rules where code='{$v[0]}'";
    $name = $db->StrQuery($sname);
    echo "<div class='list'>{$name}</div>";
}


?>

用户角色管理：

主（管理）页面：

<?php
include("../DBDA.class.php");
$db = new DBDA();
?>
<br />

<div>
    请选择用户：
    <select id="sel">
        <?php
        $sql = "select * from users";
        $attr = $db->Query($sql);
        foreach($attr as $v)
        {
            echo "<option value='{$v[0]}'>{$v[2]}</option>";
        }
        //取到第一个人的用户名
        $fuid = $attr[0][0];
        
        ?>
    </select>
</div>
<br />
<div>
    请选择角色：<br /><br />
    <?php
    $sjuese="select * from juese";
    $ajuese = $db->Query($sjuese);
    foreach($ajuese as $v)
    {
        $sxz = "select count(*) from userinjuese where userid='{$fuid}' and jueseid='{$v[0]}'";
        
        $n = $db->StrQuery($sxz);
        
        if($n>0)
        {
            echo "<input type='checkbox' class='juese' checked='checked' value='{$v[0]}' /> {$v[1]} &nbsp;";
        }
        else
        {
            echo "<input type='checkbox' class='juese' value='{$v[0]}' /> {$v[1]} &nbsp;";
        }
    }
    ?>
</div>

<br />
<input type="button" value="保存" id="btn" />

</body>
<script type="text/javascript">

$("#sel").change(function(){
        var uid = $("#sel").val();
        $.ajax({
                url:"chuli.php",
                data:{uid:uid},
                type:"POST",
                dataType:"TEXT",
                success: function(data){
                    var js = data.split("|");
                    
                    //清除选中状态
                    var ck = $(".juese");
                    ck.prop("checked",false);
                    
                    //让等于返回角色代号的选中
                    for(var i=0;i<ck.length;i++)
                    {
                        if(js.indexOf(ck.eq(i).val())>-1)
                        {
                            ck.eq(i).prop("checked",true);
                        }
                        
                    }
                    
                    }
            });
    })
    
$("#btn").click(function(){
    var uid = $("#sel").val();
    //角色代号
    var ck = $(".juese");
    var str ="";
    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,juese:str},
            type:"POST",
            dataType:"TEXT",
            success: function(){
                    alert("保存成功！");
                }
        });
    
    })
</script>

默认显示处理页面：

<?php
include("../DBDA.class.php");
$db = new DBDA();

$uid = $_POST["uid"];

$sql = "select jueseid from userinjuese where userid='{$uid}'";

echo $db->StrQuery($sql);

修改处理页面：

<?php
include("../DBDA.class.php");
$db = new DBDA();

$uid = $_POST["uid"];
$juese = $_POST["juese"];

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

//删除所有该用户的角色信息
$sdel = "delete from userinjuese where userid='{$uid}'";
$db->Query($sdel,0);

//将取到了角色信息添加进去
foreach($attr as $v)
{
    $sql = "insert into userinjuese values('','{$uid}','{$v}')";
    $db->Query($sql,0);
}
