javascript - 将具有 POST 的 PHP 变量发送到另一个 PHP 文件

Question

我正在创建一个通过 AJAX 将用户的 HTML 输入发送到 PHP 的页面，但我需要该信息在几次验证后打开另一个 PHP 页面

我尝试将该文件包含在另一个文件中并使用该变量，但我得到“索引用户不足”，认为这是因为我没有在新文件中定义它。

HTML

<div class="wrap-input100 validate-input" data-validate = "Enter username"><input class="input100" type="text" id="user" name="username" placeholder="username">
<span class="focus-input100" data-placeholder="&#xf207;"></span>
</div>

<div class="wrap-input100 validate-input" data-validate="Enter password">
<input class="input100" type="password" id="pass" name="pass" placeholder="password">
<span class="focus-input100" data-placeholder="&#xf191;"></span>
</div>

<div class="container-login100-form-btn">
<a class="login100-form-btn" id = "logBtn">
Login
</a>
</div>      

JS

$('#logBtn').click(function(event){ 
    user = document.getElementById("user").value;
    password = document.getElementById("pass").value;

    $.ajax({
        type:"POST",
        url:"login.php",
        async: false,
        data: {user:user,password:password},
        success: function(data){
            if(data == 'Administrator'){
                window.location.href='../Main/index.php';
             }
             else if(data == 'Emp'){
                window.location.href='../Main/startemp.html';
             }else{
               alert("username or password invalid");
             }
        }
        });
    });

登录.php

<?php
$servername = "localhost";
$username = "root";
$password = "asdadadas";
$dbname = "dsdvvt";

$conn = new mysqli($servername, $username, $password, $dbname);

$user = $_POST['user'];
$pass = $_POST['password'];

$sql = "SELECT * FROM users WHERE email='$user' AND clave='$pass'"; 
$result = mysqli_query($conn, $sql);

if (mysqli_num_rows($result) > 0) {
    $sql_1 = "SELECT * FROM users WHERE email='$user' AND clave='$pass' AND permisos='Administrador'";
    $result_1 = mysqli_query($conn, $sql_1);
    if (mysqli_num_rows($result_1) > 0){
        echo "Administrator";
        exit(0);
    }
    else{
        echo "Emp";
        exit(0);
    }

 } else {
    $msg = "Username or password invalid";
    echo $msg;
 }

mysqli_close($conn);
?>

index.php

<?php
include '../Login/login.php';
$one = $user;?>

我需要将在login.php中收集的信息发送到index.php，有什么办法可以做到这一点吗？

我的建议是使用 session 。

开始 session

<?php
session_start();
?>

并分配一个这样的变量:

$_SESSION['user'] = "FlowMafia";

像这样打印 session 变量。

echo $_SESSION['user'];
