Question

选择查询不想工作。它直接转到login failed，但我输入了正确的密码。

我尝试从另一个数据库中运行但是从这个表中它不想工作。

另一件事是每当我启动XAMPP时它会显示key _ buffer。

这是阻止我的查询工作的原因吗？

以下是我的代码。希望得到开发人员的一些帮助。

<?php 
session_start();
$_SESSION['message']=''; 
$mysqli=new MySQLi('127.0.0.1','root','','learning_malaysia');

if(isset($_POST['login'])) {
    $username = $mysqli->real_escape_string($_POST['username']);
    $password = md5($_POST['password']);
    $sql="SELECT * FROM tutor_register WHERE username='$username' AND password='$password' LIMIT 1;";
    $result = mysqli_query($mysqli,$sql);

    if(mysqli_num_rows($result) > 0){
        $row = mysqli_fetch_array($result);
        if (($row['username']=='sithi') && ($row['password']=='202cb962ac59075b964b07152d234b70')){
            $_SESSION['user_type'] = $row;
            $_SESSION['password'] = $row;
            $_SESSION['message'] =  "Registration successful!";
            header("location:myresuming.html");
            exit();

        } else {
            $_SESSION['username'] = $row['username'];
            $_SESSION['profile'] = $row['profile'];
            $_SESSION['message'] =  "Registration successful!";
            header("location:Welcome.php");
            exit();
        }

    } else {
        $_SESSION['message'] = "Login Failed!"; 
    }
}
