How to properly implement cutsom front-end user profile?

Question

WordPress

The question turned out to be incorrect. A big request is to remove it so as not to mislead other users. Thanks in advance.

Answer 1

1. Intercepting $_POST on init
2. wp_update_user()
3. update_user_meta()
edit_user_profile / show_user_profile are hooks in the admin, on the profile page. On the front end, they make absolutely zero sense.
