A large part of the problem is that i dont know the correct vocabulary. i dont think multiple data sets is the correct phrase, so even if you cant help with the problem - the correct phrase for what im trying to do may help me search for my own answers. I'm trying to work out how to get mutliple data sets to work, the wsdl requires... [..] <OrderItemDetailsList> <OrderItemDetail> <ProductID>string</ProductID> <QuantityOrdered>int</QuantityOrdered> <OrderItemDetail> <ProductID>string</ProductID> <QuantityOrdered>int</QuantityOrdered> </OrderItemDetail> </OrderItemDetailsList> [..] so normally i'd use something like $client = new SoapClient($wsdl,$options); $method = "DoSomething"; $params = new stdClass; $params->OrderItemDetailsList->OrderItemDetail->ProductID = 1; $params->OrderItemDetailsList->OrderItemDetail->QuantityOrdered = 2; but obviously when i add the second set of data, it just overwrites the first, i'm sure there must be away round this, but i just cant see it. wsdl http://213.123.43.101:8078/helixsopext.asmx?WSDL method description http://213.123.43.101:8078/helixsopext.asmx?op=OrderProcessAllClientProdID -- Regards Derek Almond http://www.derekalmond.com -- PHP Soap Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
