Hey guys, I am currently trying to make it so our users cannot enter the same in-game name as another user on the forum. To my knowledge, the custom userfield callback method only supports three variables, those being 'array $field, &$value, &$error'. Is there any way I could grab the user's info (who is submitting the name)?
Interesting, I wasn't aware the custom field callbacks execute in the admin CP. Anyway, for handling verification / extra processing on our custom fields I extended the actionPersonalDetailsSave function, and that doesn't get executed on the admin CP.
