在 PHP 页面之间传输变量 [英] Transfer variables between PHP pages

问题描述

我想在一个页面中获取用户输入，将其存储在一个 php 变量中并在另一个 php 页面中使用它.我试过使用会话"，但它似乎不起作用.还有其他安全的选择吗?这些信息很可能是用户名和密码.

I want to get user input in one page, store that in a php variable and use it in another php page. I have tried using 'sessions' but it doesn't seem to be working. Is there another safe alternative? This information is likely to be usernames and passwords.

推荐答案

尝试更改会话代码，因为这是最好的方法.

Try changing your session code as this is the best way to do this.

例如:

<?php
session_start();

if (isset($_POST['username'], $_POST['password']) {
    $_SESSION['username'] = $_POST['username'];
    $_SESSION['password'] = $_POST['password'];
    echo '<a href="nextpage.php">Click to continue.</a>';
} else {
    // form
}
?>

nextpage.php

<?php
session_start();

if (isset($_SESSION['username'])) {
    echo $_SESSION['username'];
} else {
    header('Location: index.php');
}
?>

但是，我可能会在会话中存储更安全的内容，例如用户 ID，而不是用户的登录凭据.

However I'd probably store something safer like a userid in a session rather than the user's login credentials.
