if（isset（$ _ SESSION [“uname”]）==（$ _COOKIE ['admin']））

Question

我正在尝试创建一个具有不同权限的示例网站，admin是管理页面，客户端是客户端页面？

这是我的PHP代码db_login

<?php

    $uname = $_POST["uname"];
    $pword = $_POST["pword"];

    require_once("../connector/db_open.php");

    $sql = "SELECT * FROM tbl_create_acc WHERE uname = '".$uname."' AND pword = '".$pword."'";
    $result = $conn->query($sql) or die ($conn->error);

    if($result->num_rows >0)
    {

        if (isset($_SESSION["uname"]) == ($_COOKIE['admin']))
        {
            $row = mysqli_fetch_array($result);
            session_start();
            $_SESSION['id'] = $row['id'];
            $_SESSION['uname'] = $row['uname'];
            $_SESSION['pword'] = $row['pword']; 
            header("Location: ../page/adminpage.php");
        }
        else
        {
            header("Location: ../page/clientpage.php");
        }

    }
    else
    {   
        header("Location: ../page/index1.php");
    }
    require_once("../connector/db_close.php");

?>
