Sync Advanced Custom Fields with BuddyPress xProfile Fields
With the BuddyForms ACF and BuddyForms Members extension in combination, you can sync any ACF form element with BuddyPress.
ACF Form Elements
The BuddyForms ACF extension comes with 2 form elements. ACF Single field or ACF Group. To sync ACF Fields with BuddyPress xProfile fields you need to use the ACF single field.
Supported Form Types
Synchronization only works for Registration forms. Please make sure you have selected the Registration form as form type. You can use Registration forms like Profile Forms. The name "Registration" is a bit misleading here.
Connect xProfile and ACF fields to enable synchronisation
In the form element under the BuddyPress tab, you can select the BuddyPress xProfile field you want to sync with this particular ACF field.
