Hi gang:
I have a situation where users can purchase stuff online.
In the last step in the process, the user clicks a "confirm purchase"
button and their credit card is checked and if it's valid, they are
awarded the product. Everything works, but it takes a little time to
check the credit card.
During the time it takes to send the credit card information to the
clearing house and get back an "Ok" with a transaction ID, the user
can click the "confirm purchase" button more than once. As such, more
than one order can be made during the process.
I was thinking of using the database to prohibit multiple "confirm
purchase" clicks made by the user, but I wanted to ask this group if
anyone has a simpler idea/solution?
Thanks,
tedd
