PHP:从会话获取用户名 [英] PHP: Get username from session

问题描述

我不太擅长PHP，但有一个小问题.我一直在玩此脚本.

I'm not very good at PHP and I have a little problem. I've been playing around with this script.

我一生都无法弄清楚如何回显已登录用户的用户名. 我试图像这样打印会话的所有信息:

And I can't for the life of me figure out how to echo the username of a logged in user. I tried to print all the information of the session like this:

var_dump($_SESSION)

但是我只是得到了哈希密码和用户级别的整数.

but I just got the hashed password and the userlevel int.

有人可以在这里帮助我吗?我只想能够回应用户名.

Can someone maybe help me here? I just want to be able to echo the username.

推荐答案

您必须将用户名存储在会话中，才能在另一个页面加载时使用，当前脚本仅将这些值存储在会话中；

You have to store the username in the session for it to be available on another page load, currently the script only stores these values in the session;

 $_SESSION['loggedin'] = $row[$this->pass_column];
 $_SESSION['userlevel'] = $row[$this->user_level];

您要做的是将$username添加到传递给login函数的会话中，如下所示；

What you have to do is add the $username to the session that is passed into the login function, like below;

$_SESSION['username'] = $username;

用户名现在将与密钥用户名一起存储在会话中.

The username will now be stored in the session with the key username.

要在其他页面上使用它，请确保在尝试使用它之前，您可以通过调用函数session_start()来启动会话.

To be able to use it on another page, make sure that before attempting to use it you initiate the session by calling the function session_start().
