Passing Arrays as Parameters to Soap Webservice in non-WSDL mode - php

Question

I am using Zend_Soap_Client to query data from a webservice provided by SAP. Since the auto-generated WSDL file has a few flaws, I use the non-WSDL mode of the client.
I managed to successfully call a webservice which only requires simple parameters, like strings. Example:
This is what SAP expects:
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:urn="urn:sap-com:document:sap:soap:functions:mc-style">
<soapenv:Header/>
<soapenv:Body>
<urn:Ze12RfcGetCustHistoryNew>
<PiDateHigh>2011-12-31</PiDateHigh>
<PiDateLow>1970-01-01</PiDateLow>
<PiKunnr>1</PiKunnr>
</urn:Ze12RfcGetCustHistoryNew>
</soapenv:Body>
</soapenv:Envelope>
This is my (working) code in PHP (with $soapClient already initialized in non-WSDL mode):
$soapClient->Ze12RfcGetCustHistoryNew(
new SoapParam(date('Y-m-d'), 'PiDateHigh'),
new SoapParam('1970-01-01', 'PiDateLow'),
new SoapParam('1', 'PiKunnr')
);
But as soon as I have to pass more complex parameters to the service, it does not work. Again, an example:
This is what SAP expects:
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:urn="urn:sap-com:document:sap:soap:functions:mc-style">
<soapenv:Header/>
<soapenv:Body>
<urn:Ze12RfcGetCustHistoryNew>
<PiDateHigh>2011-12-31</PiDateHigh>
<PiDateLow>1970-01-01</PiDateLow>
<PiKunnr>1</PiKunnr>

</PiTBelegart>
</urn:Ze12RfcGetCustHistoryNew>
</soapenv:Body>
</soapenv:Envelope>
I have tried to use a multi-dimensional array containing SoapParams, but that did not work. In WSDL mode, I could pass the params as an array, without the need of using SoapParams. How can I do this in non-WSDL mode?

Answer 1

just a "quick-hit" ... I'm working in a different environment, but initially had my soap-value troubles too.
One solution for a particular problem was to pass complex arrays this way:
$data = (object)$complexArray;
$result = $webserviceClient->getResult($data);
"Casting" to object results in a StdClass object ... which often works fine for webservices.
Good Luck!

Answer 2

I have not come up with a nice solution for this yet - currently I pass the parameters to the client object as raw xml. That works, but does not seem to be the best way to do this. This is my code now:
$params = '
<PiDateHigh>2011-12-31</PiDateHigh>
<PiDateLow>1970-01-01</PiDateLow>
<PiKunnr>1</PiKunnr>
<PiTBelegart>
<item>
<BelegartTyp>FAKTURA</BelegartTyp>
<Belegart>ZF2</Belegart>
</item>
</PiTBelegart>
';
$result = $this->_client->Ze12RfcGetCustHistoryNew(new SoapVar($params,XSD_ANYXML));
