如何在用户在我的网站上执行多步操作时标记用户的进度？

Question

I need some implementation like they do in websites like Khanacademy or Edx-- when you log back in, they tell you, "You were currently in this section, continue from here?"

The only way I can think of doing this is having a column in database and have a form for each and every section (like lesson 1, lesson 2, lesson 3) and whenever the user clicks in the section, the form gets submitted and it updates the column in the database to remember. Will this approach work or there's a better way of doing this?

Answer 1

You don't need to submit a form.

Personally, I have in my "foot.php"-like code that updates the users table with lastseen=now(), lastpage=:current_page and this allows me to not only know what they were doing last, but also when they were doing it, so I can construct a Users Online page which shares this information.

Of course, applications vary, but the general idea is usable anywhere.
