3.49. OnFly

Enables on-the-fly item additions to the shopping cart. If set to the name of a valid UserTag, that tag definition will be used to parse and format the item with the following call:

   $item = Vend::Parse::do_tag($Vend::Cfg->{OnFly},
                                   $code,
                                   $quantity,
                                   $fly[$j],
                               );

$fly[$j] is the value of mv_order_fly for that item. A default onfly tag is provided by Interchange. For more information, see the section that describes how to set up an on-the-fly item.
