PHP - 没有会话,没有帖子 - 还有什么?

I am making a small two page php project for someone. I have a login page which redirects to a page with 20-odd checkboxes populated from the DB.

On login if the details are valid it creates a session user and a few others. Locally everything is fine.

On the server however, it's not configured to use any custom session path and apparently is a shared hosting eviroment so I can't change the php.ini to include the session info.

It seems that the host is also blocking php post information.

Is there any other way I can simulate the same effect as having a session variable?
