Thanks Ed for replying to my posts...
I'll explain to you what is my problem:
We have been accepted at www.worldpay.com for the "Select" service.
Their setup is not really what I anticipated. Basically they host the CC and
billing info and place cookies on clients site so that they dont have to
re-enter their info again.
Now, if you want, they can trigger a CGI on your site so that you actually
know if the transaction was succesfull.
So at first you send a POST containing a few hidden fields (i.e.: instId,
cartId, amount, and other custom fields if you want) like this:
(this is the GET method its just for illustration purpose)
https://select.worldpay.com/wcc/purchase?instId=xxx&cartId=xxxx&amount=xxxx&
currency=xxx
Then, you are presented with a page containing billing info (*****if you
passed it*****) and input fields for CC info.
Problem #1
To pass the billing info, I need to map the values to the names they need.
Not the fields i have in my db. This is tricky as I can't change the names
of the db and the info does not really exist yet (its being entered).
Problem #2
I need a callback that will get the status sent back by WorldPay to know if
the orders are valid. And from there I'm completely lost...I dont even know
where to start. I could pass the session Id and cartId and they would send a
post on one of my pages parsed by interchange and i could even set a
password from their admin section to make sure the response comes from them.
I hope someone can at least give me some tips as very few people are able to
help me right now.
J.-P.
