[FX.php List] cXML punch-out

[Steve Winter]

Hi Frank,

So, on WS#1 the result of the link which they click needs to have this result (sort-of pseudo code)
	POST PunchOutSetupRequest
	TO: http://webServer2/cxml.php

cxml.php needs to be a PHP file on your WS#2 which can accept that XML file being posted to it (you don't need to upgrade to PHP 5 to work with XML docs, though some aspects of that are easier if you don... really, that's the least of your worries by the sounds of it ;-) It receives the file, does some processing (setting up a cart account etc) and then returns the required XML document as its response (build the XML document, then send the XML header, instead of HTML headers when you output the results...

(Based on my quick read of the cXML it would appear that the URL they are to be redirected to should be included in the returned response XML...? do you have sample messages which will be received/sent...? these might help you to get your head around what needs to happen)

When the user has finished shopping, your PHP cart needs to;
	POST PuchOutOrderMessage
	TO: http://webServer1/whateverTheInterfaceURLis
Wait for (and process) the XML file which will be returned, then issue a redirect to the user browser to send them back to WS#1

Does this make sense...?? does it help you see any sort of way forward...??

Cheers
Steve
