Please Help: Database Field Management or Edit

[general_paton99]

I am trying to find a way to change database fields in phpBB to reference my current fields. I have a current member database that uses the current fields listed below. I've changed the table setting in constants.php so it points to the correct table. But because it refers to the phpBB fields my current users can not login with their current accounts.

I need to change 4 field names

phpBB ->current

user_id ->member_id
username ->user_name
user_password -> password
user_email -> email

I've added all the other phpbb_users fields to my table.

Is there a mod, convertor, guide out there that can help me do this.

Thank you to anyone with a suggestion.
