=head1 NAME
UserDB.pm -- Interchange User Database Functions
=head1 SYNOPSIS
userdb $function, %options
=head1 DESCRIPTION
The Interchange user database saves information for users, including shipping,
billing, and preference information. It allows the user to return to a
previous session without the requirement for a "cookie" or other persistent
session information.
It is object-oriented and called via the [userdb] usertag, which calls the
userdb subroutine.
It restores and manipulates the form values normally stored in the user session
values -- the ones set in forms and read through the C<[value variable]> tags.
A special function allows saving of shopping cart contents.
The preference, billing, and shipping information is keyed so that different
sets of information may be saved, providing and "address_book" function that
can save more than one shipping and/or billing address. The set to restore
is selected by the form values C<s_nickname>, C<b_nickname>, and C<p_nickname>.
=cut
=head1 METHODS
User login:
$obj->login(); # Form values are
# mv_username, mv_password
Create account:
$obj->new_account(); # Form values are
# mv_username, mv_password, mv_verify
Change password:
$obj->change_pass(); # Form values are
# mv_username, mv_password_old, mv_password, mv_verify(new)
Get, set user information:
$obj->get_values();
$obj->set_values();
$obj->clear_values();
Save, restore filed user information:
$obj->get_shipping();
$obj->set_shipping();
$obj->get_billing();
$obj->set_billing();
$obj->get_preferences();
$obj->set_preferences();
$obj->get_cart();
$obj->set_cart();
=head2 Shipping Address Book
The shipping address book saves information relevant to shipping the
order. In its simplest form, this can be the only address book needed.
By default these form values are included:
s_nickname
name
address
city
state
zip
country
phone_day
mv_shipmode
The values are saved with the $obj->set_shipping() method and restored
with $obj->get_shipping. A list of the keys available is kept in the
form value C<address_book>, suitable for iteration in an HTML select
box or in a set of links.
=cut
@S_FIELDS = (
qw!
s_nickname
company
name
fname
lname
address
address1
address2
address3
city
state
zip
country
phone_day
mv_shipmode
!
);
=head2 Accounts Book
The accounts book saves information relevant to billing the
order. By default these form values are included:
b_nickname
b_name
b_address
b_city
b_state
b_zip
b_country
b_phone
mv_credit_card_type
mv_credit_card_exp_month
mv_credit_card_exp_year
mv_credit_card_reference
The values are saved with the $obj->set_billing() method and restored
with $obj->get_billing. A list of the keys available is kept in the
form value C<accounts>, suitable for iteration in an HTML select
box or in a set of links.
=cut
@B_FIELDS = (
qw!
b_nickname
b_name
b_fname
b_lname
b_address
b_address1
b_address2
b_address3
b_city
b_state
b_zip
b_country
b_phone
purchase_order
mv_credit_card_type
mv_credit_card_exp_month
mv_credit_card_exp_year
mv_credit_card_reference
!
);
=head2 Preferences
Preferences are miscellaneous session information. They include
by default the fields C<email>, C<fax>, C<phone_night>,
and C<fax_order>. The field C<p_nickname> acts as a key to select
the preference set.
=head2 Locations
There are several database locations that have special purposes. These
