Hi All,
I have a
jsp which iterates through shop offers and presents them in a table on the page.
Therefore I have a number of parameters named offerId, and an equal number of parameters named
quantity. When the form is submitted I want the 'quantity' ordered to match up with the 'offerId', ie quantity[0] will be from the same record as offer[0]
The following code seems to show that they do match up:
String[] offers = request.getParameterValues("offerId");
String[] quantity = request.getParameterValues("quantity");
for(int i=0; i < offers.length; i++)
System.out.println("OfferId: " + offers[i] + " | " + "Quantity: " + quantity[i]);
I just want too make sure though, in the above situation am I guaranteed that the 2 will match up?
I don't want to end up with a situation where accidently the wrong item is ordered or the wrong quantity? Is there a better way to do this?
Thanks for any help
Joel
