This is probably too late to help anyone, but I just had to figure this out myself, and this worked for me within register-plus.php:
<?php echo get_usermeta($un->ID, 'badge_number'); ?>
“badge_number” being my custom field “Badge Number”
Just had to figure out how to do the exact same thing. This worked for me within register-plus.php:
<?php echo get_usermeta($un->ID, 'badge_number'); ?>
“$un->ID” is how to call the user’s ID in register-plus.php
And replace “badge_number” with your custom field name. Lower-case with underscore instead of spaces.
