I added a pipe but the pipe doesn't work. This is what I have:
@Pipe({name: 'grandtotal'})
export class GrandTotalPipe implements PipeTransform {
sub_total = 0;
product_price = 0;
quantity = 0;
transform(product_price: number, quantity: number, sub_total: number) {
sub_total = product_price * quantity;
sub_total += sub_total;
return sub_total;
}
}
and in the HTML:
<div>Grand Total {{product_price | grandtotal: quantity : sub_total}}</div>
