Hi all,

 

I have tested before to get help, no success so I try once more... I need some help with a payment script to SCB bank in Thailand. It is talking to the bank and all the only problem I got now is the error / success handling up on the return from the bank.

 

I know their is a number of lines in the module I have modified but I can understand how to change them. I am a begginer with PHP and got totaly stuck!

 

I hope some one here can help me out to change these lines... This is what I have done...

   }
 }

Now the responce from SCB in Thailand will look like this:

 

Authorization Request Response

 

Command CreditResponse ? response from SIPS Authorization request can be sent by 2 channels. (SIPS responds via both channels):

 

3.1 "backURL" : field 45 from Authorization Request format

 

After the payment process was done, SIPS would return the webpage address to the backURL using the same authorization request format and together with the backurl, SIPS will include a response parameter advising of the result of the process.

 

Example:

 

If "backURL=http://www.test.com/return.asp?return=1"

 

SIPS would return to the backURL page and also add the response to the backURL.

 

http://www.test.com/return.asp?return=1&response=approved

 

Or if "backURL=http://www.test.com/return.asp"

 

SIPS would return to the backURL page and also add the response to the backURL.

 

http://www.test.com/return.asp?response=approved

 

response=canceled (Customer canceled from SIPS Payment, No payment has been done.)

 

response=error (Transaction in process, waiting for creditcard approval result.)

 

response=approved (Creditcard authorization approved)

 

response=declined (Creditcard authorization declined)

 

response=outofservice (SIPS temporary out of service)

 

Hope some one can help me out...

 

 

Sincerely

Johan
