Using Form Data

Next, we return to the TicketConfirm class—the one that gets called when the user clicks on the Complete Order button.

We need to determine if an e-mail address was entered. We can access the values of form elements via the %request object's Data Property.

If this value is not a zero-length string, we have some work to do.

        If ($G(%request.Data("OrderEmail",1)) '= "") {

        Write "Your order expired before it was completed."
