这是一道概念题。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。
我希望用户能够制作自己的特定待办事项。因此，当他们登录时，他们可以看到自己的待办事项并为自己创建待办事项。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();
?>

}
}
}
echo "<script> window.location.href = 'http://localhost:8012/phpForm/Profile.php' </script>";
}
}
else {
echo "<script>sweetAlert('Oops...', 'Authentication Failed', 'error');</script>";
}
}
}
?>

还有我的个人资料页面:
<?php
session_start();
require_once('PhpConsole.phar');
require_once('connection.php');
ob_start();
require('index.php');
$data = ob_get_clean();
ob_end_clean();

最佳答案
既然是概念题，而且你提到登录/注册系统已经做好了，你需要做的是:
- 记录他们保存一个独特的
$_SESSION['id'], 或可过期的唯一 key 。- 此外，您可以保存 cookie 以识别他们的帐户
在todo.php页:
- 通过检查
$_SESSION['id']确保他们已登录(如果已设置，则重定向到某处或弹出消息)。 - 通过
SELECT * FROM todo WHERE user='id'查询他们当前存储的 TODO - 显示
<textarea>或类似于存储新的 TODO(您可以通过POST到同一页面)。 - 如果页面得到
POST要求:- 通过
INSERT INTO todo('id', 'sanitized $_POST["text"]')存储新的 TODO
- 通过
此外，请始终确保在执行任何这些查询之前清理变量。
