  • 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="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);
    }
