Hello, first check if these users are already registered on your site.

If they are, it is better to do it manually from the back-office via the Tutor plugin.

If you want to make sure that each user is registered to this course when he/she registers on the site, write the code I put above and specify the course id.

These users are already registered on my site. I want to enroll hundreds of students (registered users) to one specific course, but I don't know how to write the code, and where to put it.

Is it the functions.php or where?
