What events trigger when a user creates a new account and activates it

After a long conversation with ChatGPT, I believe I have (in theory) the basics down.

There are some action events I could hook:

For early intervention

  • signup_user – the earliest point
  • after_signup_user – a little later, when the activation link has been sent

There were two hooks mentioned that I’m less sure of (will edit answer when I have learned more)

  • wpmu_activate_user – I’m guessing this is when the activation link is clicked
  • wpmu_signup_user_notification – not sure at all about this one, but it might be a bit later for me

However, we also talked about a filter that might be good – validate_user_signup, which would catch things soonest and prevent junk data from ever entering the database to start with.

Edit: Upon further conversation, bp_signup_validate came up as a confirmed BuddyPress event trigger, which might also prove useful. It seems to fire around the same time as signup_user during the form validation phase.
