session_start();
if(!empty($_POST["login"])) {
    $conn = mysqli_connect("localhost", "root", "", "blog_samples");
    $sql = "Select * from members where member_name = '" . $_POST["member_name"] . "' and member_password = '" . md5($_POST["member_password"]) . "'";
    $result = mysqli_query($conn,$sql);
    $user = mysqli_fetch_array($result);
    if($user) {
            $_SESSION["member_id"]         = $user["member_id"];

                setcookie ("member_login",$_POST["member_name"],time()+ (10 * 365 * 24 * 60 * 60));
                setcookie ("member_password",$_POST["member_password"],time()+ (10 * 365 * 24 * 60 * 60));
            } else {
                if(isset($_COOKIE["member_login"])) {
                    setcookie ("member_login","");
                }
                if(isset($_COOKIE["member_password"])) {
                    setcookie ("member_password","");
