Question

各位程序员下午好，我是一个新的PHP代码，在上一个问题我询问注册和登录页面问题之间的关系。按照说明申请后，问题解决了。现在我再试一次，选择查询不想工作。虽然我输入了正确的密码，但它直接登录失败。我尝试从另一个数据库工作，但从这个表，它不想工作。另一件事是每当我启动xampp它显示键_缓冲区。这是否使我的查询无效。下面我附上我的代码，希望得到开发人员的帮助。非常感谢。

Register Php

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



if(isset($_POST['login'])) {
    $username = $mysqli->real_escape_string($_POST['username']);
        $password = md5($_POST['password']);
         $sql="SELECT * FROM users WHERE username='$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!"; 
    }

}



?>
