NAME

UserDB.pm -- Interchange User Database Functions

SYNOPSIS

userdb $function, %options

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 "[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 "s_nickname", "b_nickname", and "p_nickname".

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();
 
 

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 "address_book", suitable for iteration in an HTML select box or in a set of links.

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 "accounts", suitable for iteration in an HTML select box or in a set of links.

Preferences

Preferences are miscellaneous session information. They include by default the fields "email", "fax", "phone_night", and "fax_order". The field "p_nickname" acts as a key to select the preference set.
