Some parameters contain a set of objects — e.g., all items in an order — rather than a single value.
In your template, you can add a block for each of these kinds of objects:
@{ for item in Order.Items }
Price: ${ item.Price }
@{ end for }
In this example, `item` is an arbitrary name attributed to one order item so that you can use its parameters. Inside the `for...end for` block you can access a particular order item. In addition, this block can include an arbitrary HTML code, conditions, and even nested loops.
If the example above contains three order items, the output will be:
> Price: 5
> Price: 10
> Price: 25
Also, you can use the "set" keyword in `@{ set a = a + 1 }` to add a counter.
Here are some possible use cases:
To display the total purchase value:
@{ set Total = 0 }
@{ for product in Session.GetAddedToListProducts("Cart").Take(10) }
@{ set Total = Total + product.Price }
@{ end for }
To list the product IDs separated by a comma:
@{ set Ids = "" }
@{ for product in Products.GetBySegment("PopularInStock").Take(10) }
@{ if Ids != "" }
@{ set Ids = Ids & "," }
@{ end if }
@{ set Ids = Ids & product.IDs.C1 }
@{ end for }
