ASP/perl tag calls:

DESCRIPTION

Product discounts can be set upon display of any page. The discounts apply only to the customer receiving them, and are of one of three types:

    1. A discount for one particular item code (code/key is the item-code)
    2. A discount applying to all item codes (code/key is ALL_ITEMS)
    3. A discount applied after all items are totaled
       (code/key is ENTIRE_ORDER)

The discounts are specified via a formula. The formula is scanned for the variables $q and $s, which are substituted for with the item quantity and subtotal respectively. In the case of the item and all items discount, the formula must evaluate to a new subtotal for all items of that code that are ordered. The discount for the entire order is applied to the entire order, and would normally be a monetary amount to subtract or a flat percentage discount.

Discounts are applied to the effective price of the product, including any quantity discounts.

To apply a straight 20% discount to all items:

    [discount ALL_ITEMS] $s * .8 [/discount]

or with named attributes:

    [discount code=ALL_ITEMS] $s * .8 [/discount]

To take 25% off of only item 00-342:

    [discount 00-342] $s * .75 [/discount]

To subtract $5.00 from the customer's order:

    [discount ENTIRE_ORDER] $s - 5 [/discount]

To reset a discount, set it to the empty string:

    [discount ALL_ITEMS][/discount]

Perl code can be used to apply the discounts. Here is an example of a discount for item code 00-343 which prices the second one ordered at 1 cent:

    [discount 00-343]
    return $s if $q == 1;
    my $p = $s/$q;
    my $t = ($q - 1) * $p;
    $t .= 0.01;
    return $t;
    [/discount]

If you want to display the discount amount, use the [item-discount] tag.

    [item-list]
    Discount for [item-code]: [item-discount]
    [/item-list]

Finally, if you want to display the discounted subtotal in a way that doesn't correspond to a standard MiniVend tag, you can use the [calc] tag:

    [item-list]
    Discounted subtotal for [item-code]: [currency][calc]
                                            [item-price noformat] * [item-quantity]
                                            [/calc][/currency]
    [/item-list]

%% dump %% Prints a dump of the current user session as expanded by Data::Dumper. Includes any CGI environment passed from the server.

%% either %% The [either]this[or]that[/either] implements a check for the first non-zero, non-blank value. It splits on [or], and then parses each piece in turn. If a value returns true (in the Perl sense -- non-zero, non-blank) then subsequent pieces will be discarded without interpolation.

Example:

  [either][value must_be_here][or][bounce href="[area incomplete]"][/either]
