PHP Soap Complex Data Type? - php

Question

I am trying to consume a PHP Soap service however I seem to have having trouble with a complex/abstract type.
This is the SOAP call generated using SOAP UI :-
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:lin="http://llu.webservices.opalonline.co.uk/LineCharacteristicsWS">
<soapenv:Header/>
<soapenv:Body>
<lin:GetLineCharacteristics>
<lin:request>
<!--Optional:-->
<lin:UserCredentials>
<!--Optional:-->
<!--Optional:-->
<lin:Username>testUser</lin:Username>
<lin:Password>testPass</lin:Password><lin:AgentID>1234</lin:AgentID>
</lin:UserCredentials>
<lin:RequestDetails xsi:type="lin:TelephoneNumberRequest" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<lin:TelephoneNumber>123456789</lin:TelephoneNumber>
</lin:RequestDetails>
<lin:UserConsent>Yes</lin:UserConsent>
<lin:ServiceType>MPF</lin:ServiceType>
</lin:request>
</lin:GetLineCharacteristics>
</soapenv:Body>
</soapenv:Envelope>
Here is my PHP code :-
$call = new StdClass();
$call->request = new StdClass();
$call->request->UserConsent = "Yes";
$call->request->ServiceType = "MPF";
$call->request->UserCredentials = new StdClass();
$call->request->UserCredentials->Username="testUser";
$call->request->UserCredentials->Password="testPass";
$call->request->UserCredentials->AgentID=1234;
$call->request->RequestDetails = new StdClass();
$call->request->RequestDetails->TelephoneNumber = "123456789";
$url = "https://llu.webservices.opalonline.co.uk/LineCharacteristicsWSV6/LineCharacteristicsWS.asmx?wsdl";
$client = new SoapClient($url, array('trace' => 1, exceptions=> 1,'soap_version' => SOAP_1_1));
$result = $client->GetLineCharacteristics($call);
echo $client->__getLastRequest();
echo $client->__getLastResponse();
When I run the code, the following error is generated :-
Fatal error: Uncaught SoapFault exception: [soap:Client] Server was unable to read request. ---> There is an error in XML document (2, 382). ---> The specified type is abstract: name='RequestType', namespace='http://llu.webservices.opalonline.co.uk/LineCharacteristicsWS', at http://llu.webservices.opalonline.co.uk/LineCharacteristicsWS'>. in /Users/jamesormerod/NetBeansProjects/fpdfDev/TestClass.php:23
Can anyone help?

To be able to send the request well formed with correct type and namespace, you must use both classes named as the required elements and a classmap that maps the elements to the classes.
The WsdlToPhp project can help you generate the classes and the classmap. You can use the project at wsdltophp.com.
Then if for example you generate the package with the name LineCharacteristics, you'll be able to send the request using this sample code:
$lineCharacteristicsServiceGet = new LineCharacteristicsServiceGet();
// sample call for LineCharacteristicsServiceGet::GetLineCharacteristics()
$details = new LineCharacteristicsStructTelephoneNumberRequest('[phone]');
$request = new LineCharacteristicsStructGetLineCharacteristicsRequest($details, LineCharacteristicsEnumUserConsentEnum::VALUE_YES, LineCharacteristicsEnumServiceTypeEnum::VALUE_MPF);
$userCredentials = new LineCharacteristicsStructCredentials(11111,'********','********');
$request->setUserCredentials($userCredentials);
$characteristics = new LineCharacteristicsStructGetLineCharacteristics($request);
$r = $lineCharacteristicsServiceGet->GetLineCharacteristics($characteristics);
echo implode("\r\n", array($lineCharacteristicsServiceGet->getLastRequestHeaders(),$lineCharacteristicsServiceGet->getLastRequest(),$lineCharacteristicsServiceGet->getLastResponseHeaders(),$lineCharacteristicsServiceGet->getLastResponse()));
if($r)
print_r($lineCharacteristicsServiceGet->getResult());
else
print_r($lineCharacteristicsServiceGet->getLastError());
