Re: [ic] Many to many price schema

Hi again...i modified your routine according to my database structure:

UserTag calc_price Order code quantity
UserTag calc_price Routine <<EOF
sub {
    my ($code, $quantity);

if ($Vend::Interpolate::item) {
$code = $Vend::Interpolate::item->{code};
$quantity = $Vend::Interpolate::item->{quantity};
} else {
($code, $quantity) = @_;
    }

# sanity check
if ($code !~ /^\d+$/ || $quantity !~ /^\d+$/) {
Log ("Wrong input for calc_price: CODE $code QUANTITY $quantity");
        return;
    }
 my $db = Vend::Data::database_exists_ref('products');
 my $keys = $db->query ("select price from prezzi where sku='$code' and nome
= '$Vend::Session->{username}' and min<='$quantity' and max>='$quantity'");
my $price;

if (@$keys) {
# fallback price
$price = $keys->[0]->[0];
# check for appropriate price
#for (my $i = 0; $i < @$keys; $i++) {
#if ($quantity > $keys->[$i]->[1]) {
#$price = $keys->[$i]->[0];
#}
#}
}
else {
 my $keys = $db->query ("select price from prezzi where sku='$code' and nome
is null and min<='$quantity' and max>='$quantity'");
 $price = $keys->[0]->[0];
}


}
EOF

CommonAdjust [calc_price]

and using the tag:

[calc_price code="405153283" quantity="1"]

works well...

the problem is now that the tag [item-price] does not show the correct prize
and ordering the product the basket does not show the correct price.
How can i do to show always the prize calculated by the routine ??
