UserDB.pm -- Interchange User Database Functions

userdb $function, %options

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".

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();

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.

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 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.
