UserTags for Currency Conversion
****** message to minivend-users from Barry Treahy <treahy@mmaz.com> ******
On 3/4 Dan Busarow provided a nice example of how to deal with VAT in a
subtotal senario. I have added the tag, but not tested it. What I have
attempted to do was create a second tag based on that example that
would take the [discount-price] and manipulate it, ie:
[ustouk][discount-price][/ustouk]
and it works for the unit price, but does not alter the contents of the
[item-subtotal] automatically and there for the remaining subtotals are
incorrect. The defined UserTag is :
UserTag ustouk HasEndTag
UserTag ustouk Interpolate
UserTag ustouk Routine sub { ($a) = @_; return
Vend::Util::currency($a*1.12/1.6+70.00); }
what am I doing wrong?
If I put [item-subtotal] inside my tag, it still doesn't work because
the equation assumes a unit price and that the altered unit price would
then be extended. If I apply the equation after extension, it doesn't
add enough 70 increments per unit, only one...
