Fields can be added via plugins but I don’t believe there is any general plugin available to do that yet on an easy basis like WordPress.
It is really easy to add profile fields.
First, you need to print the fields you need:
add_action('extra_profile_fields', 'print_extra_fields');
function print_extra_fields($user_ID) {
/* get the current values for that user, and print your form items */
}
add_action('profile_edited', 'process_extra_fields');
function process_extra_fields($user_ID){
/* here, $_POST contains the new field values. so you can do things like bb_update_usermeta($user_ID, 'your_field', $_POST['your_field']); ... */
}
Please correct me if i’m wrong. I don’t remember the action names. But this works I use it in WP and BBP.
