Hi there everyone.
Right I have scoured everywhere to find out how to do this and I
haven't the foggiest...
I am building a shopping cart that uses an external clearing house
[world pay].
My shopping cart sequence is :
Checkout page [show the contents of the cart etc] ----> Confirmation
confirm the details of the cart, finalise totals etc -------> Forward
to world pay for card transaction -------> On completion world pay does
a "call back" that executes a page on my site which effectively
confirms that the trasaction took place [puts in transax ids etc into
my database for order management].
This works great however what has happened is that sometimes world pays
call back doesn't fire when it should have due to internet congestion
etc the request times out. Because the order isn't confirmed until we
get the call back needless to say this causes a problem.
So what I want to do is basically put an invisible page in between our
confirmation screen [where the user says "Yes this is correct take me
to world pay"] and the first world pay screen [enter your card
details].
Where I am having troubles though is I want this page to be invisible.
I need to submit the confirmation page form to this hidden page and
then *automatically" submit the resulting form to world pay - and move
the users' browser along as well. I don't want the user to have to
submit the page again though and I certainly don't want to hack it with
a onLoad="form.Submit()" type thing in Javascript on my hidden page -
it has to be accessible for people without JavaScript switched on.
I'm sure it is a case of writing the headers or soemthing but the only
things I can find are using fsockopen which submits a request and
downloads the results into the originating page. I want to forward the
browser entirely.
Any help would be very much appreciated.
Kind regards
