CakePHP SoapClient drops fields? - php

Question

My app uses CakePHP (2.2.5) to get data from a SOAP server. I put logging into the SoapSource.php connector to see the XML returned and to display the array returned:
$result = $this->client->__soapCall($method, array('parameters' => $tParams));
Logger::write('SOAP Last Response', $this->client->__getLastResponse(), 3, 'transaction');
Logger::write('SOAP Last Response Object', print_r($result, TRUE), 3, 'transaction');
But what I'm seeing in the log is that two (recently-added) fields present in the XML are missing from the array, specifically, the last two before the RPList (formatted here but otherwise verbatim):
<transactionResult>
<id>test</id>
<resultCode>0</resultCode>
<ReadScheduledRecordingsRsp>
<RecordingDefinitionList>
<RecordingDefinition>
<RDId>d8c16d8f-67c6-469a-83c3-d51d8f8859a9</RDId>
<Title>The Young and the Restless</Title>
<SeriesId>4422</SeriesId>
<KeepUntil>SpaceIsNeeded</KeepUntil>
<StartPadSeconds>0</StartPadSeconds>
<EndPadSeconds>0</EndPadSeconds>
<Frequency>EveryDay</Frequency>
<KeepAtMost>0</KeepAtMost>
<Priority>23</Priority>
<ShowType>Any</ShowType>
<AirtimeDomain>SpecificTime</AirtimeDomain>
<ChannelDomain>SpecificChannel</ChannelDomain>
<RPList>
...
Followed by:
ARRAY
(
[transactionResult] => stdClass Object
(
[id] => test
[resultCode] => 0
[ReadScheduledRecordingsRsp] => stdClass Object
(
[RecordingDefinitionList] => stdClass Object
(
[RecordingDefinition] => Array
(
[0] => stdClass Object
(
[RDId] => d8c16d8f-67c6-469a-83c3-d51d8f8859a9
[Title] => The Young and the Restless
[SeriesId] => 4422
[KeepUntil] => SpaceIsNeeded
[StartPadSeconds] => 0
[EndPadSeconds] => 0
[Frequency] => EveryDay
[KeepAtMost] => 0
[Priority] => 23
[ShowType] => Any
[RPList] => stdClass Object

I'm guessing I just forgot or didn't know to do something, but I don't know what. It's just very suspicious that the two fields that don't work are the two that were just added, but I can't find any place where the fields are enumerated.
The WSDL doesn't specify any fields at all, just that there will be a bunch of data inside a transactionResult.
In the connect call, the options likewise don't specify any fields.
It all worked fine until the back-end added those two fields, and it all still works fine, except that I can't see the 2 new fields in the object.
Any ideas?

It would be nice to see the XML for RPList. What version of PHP/libxml?
Have you actually validated the XML returned by __getLastResponse()?
It sounds to me like your using WSDL mode for the client but your WSDL file lacks precision. Try using a WSDL which actually describes the data being served up by the API.
Am I understanding that the $result object when dumped lists RPList but the value is not what you expect? If so you might be able to get away with adding the SOAP_SINGLE_ELEMENT_ARRAYS option to the clients constructor: new SoapClient($wsdl, array('features' => SOAP_SINGLE_ELEMENT_ARRAYS));. That's a long shot though. Need to see WSDL and full output from __getLastResponse().
Any errors? Try wrapping the call like so:
try {
$client = new SoapClient ('http://yoursite.com?WSDL',
array("trace" => 1,
"exceptions" => true,
"cache_wsdl" => WSDL_CACHE_NONE,
"features" => SOAP_SINGLE_ELEMENT_ARRAYS)
);
$result = $client->SomeMethod($data);
} catch (SoapFault $exception) {
var_dump($exception);
} catch (Exception $exception) {
var_dump($exception);
}
Short of fixing the WSDL/XML response your workaround seems like the best solution.
