这是一个概念问题。现在我有一个注册/登录和一个使用php和mysql构建的个人资料页面系统，但我有一个问题。
我希望用户能够自己制作特定的待办事项。因此，当他们登录时，他们可以看到他们的待办事项并为他们自己创造他们的待办事项。只有他们的登录才能访问他们的待办事项。但我不明白如何在php / mysql中做到这一点。
这是我的登录页面：
<?php
session_start();
require_once('PhpConsole.phar');
require_once('connection.php');
ob_start();
require('index.php');
$data = ob_get_clean();
ob_end_clean();
?>

答案 0 :(得分：1)
由于这是一个概念问题，并且您提到登录/注册系统已经完成，您需要做的是：
$_SESSION['id']或可过期的唯一键。
在todo.php页面中：
$_SESSION['id']确认他们已登录（如果已设置，则重定向到某处或弹出消息）。SELECT * FROM todo WHERE user='id' <textarea>或类似内容以存储新TODO（您可以通过POST将其存储到同一页面。）POST请求：
INSERT INTO todo('id', 'sanitized $_POST["text"]') 此外，在执行任何这些查询之前，请务必确保对变量进行清理。
