Question

如果我的代码或我的数据库有什么问题？

我的代码

    if(isset($login)){
        if($sbg=='administrator'){
            $login = mysql_query("SELECT * FROM administrator WHERE email='$email' AND password='$pass'");
            $rows= mysql_num_rows($login);
            if($rows==0){
                $data = mysql_fetch_array($login);
                $_SESSION['login']      = true;
                $_SESSION['nama']       = $data['nama'];
                $_SESSION['email']      = $data['email'];
                $_SESSION['password']          = $data['password'];
            }else{

Answer 1

看起来你必须改变

if($rows==0)

与

if($rows>0)

Answer 2

你把代码放错了。

if($rows!=0){
                $data = mysql_fetch_array($login);
                $_SESSION['login']      = true;
                $_SESSION['nama']       = $data['nama'];
                $_SESSION['email']      = $data['email'];
                $_SESSION['password']          = $data['password'];
            }else{

Answer 3

if(isset($login)){
        if($sbg=='administrator'){
            $login = mysql_query("SELECT * FROM administrator WHERE email='$email' AND password='$pass'");
            $rows= mysql_num_rows($login);

            if($rows>0){
                $data = mysql_fetch_assoc($login);
                session_start();
                $_SESSION['login']      = true;
                $_SESSION['nama']       = $data['nama'];
                $_SESSION['email']      = $data['email'];
                $_SESSION['password']          = $data['password'];
            }else{
}

你可以只回显$行，知道如果$ rows显示0或者没有结果，请检查你的mysql查询。

无法使用管理员登录？
