Hi, I need to update a user's additional custom field when he signs up using the signup.php AND when he/she upgrades using member.php?tab=add_renew. I guess it would involve sth like this: Code: $user['data']['my_field'] = 'new_value_upon_signup'; but I'm not sure where to insert it. Does this go on the template files using smarty, or on the signup.php and member.php? And where should it be placed? Thanks in advance! p.s. I should add that this is a common field. Then it doesn't need to be added to the database, is that correct?
