Explanation
Want to add extra fields to user profiles in WordPress? This code snippet does just that by adding fields for a phone number and address.
Adding Fields to User Profiles:
- When viewing or editing a user profile, two new fields appear: one for the phone number and another for the address.
- These fields are added using hooks that display them on the user profile page.
Saving the Data:
- When a user updates their profile, the data entered in these fields is saved securely.
- The code checks if the current user has permission to edit the profile before saving.
Adding Fields to Registration:
- New users can also enter their phone number and address during registration.
- The fields are added to the registration form using a hook.
Saving Registration Data:
- Once a new user registers, their phone number and address are saved to their profile.
This setup ensures that both existing and new users can have additional information stored in their profiles, making it easy to manage extra details without needing a plugin.
