I want to use Wordpress for the user management of a simple web app.
What I really need to do:
- Check if a user is logged in
- Save meta data to a logged in user
- Read meta data of a logged in user
Doing the register process in my web app would be nice, too, but it would also work on another page.
Is it possible to do these things "outside" of the WP installation (but on the same domain)? For example via ajax requests?
Where can I start?
I just read about including wp_load.php to use the WP functions. Is that a clever approach?
Thank you so much!
