Array of complex type parameters in ckWebServicePlugin are Null - soap

Question

I'm making a webservice with the ckWebServicePlugin in symfony.
I managed to make a method with a simple type in parameter and a complex type in return and it worked well, but when i tried to get an array of complex type in parameter it seems to return me a null value;
/api/actions.class.php
/** Allow to update request
*
* #WSMethod(name='updateRequests', webservice='api')
*
* #param RequestShort[] $arrRequests
*
* #return RequestShort[] $result
*/
public function executeUpdateRequests(sfWebRequest $request)
{
$res = $request->getParameter('$arrRequests');
$this->result = $res;
return sfView::SUCCESS;
}
and this is my soap client
$test = array(array('request_id' => 1, 'statut' => 3), array('request_id' => 2, 'statut' => 3),);
$result = $proxy->updateRequests($test);
and this is my RequestShort type
class RequestShort {
/**
* #var int
*/
public $request_id;
/**
* #var int
*/
public $statut;
public function __construct($request_id, $statut)
{
$this->request_id = $request_id;
$this->statut = $statut;
}
}
and finally, my app.yml
soap:
# enable the `ckSoapParameterFilter`
enable_soap_parameter: on
ck_web_service_plugin:
# the location of your wsdl file
wsdl: %SF_WEB_DIR%/api.wsdl
# the class that will be registered as handler for webservice requests
handler: ApiHandler
soap_options:
classmap:
# mapping of wsdl types to PHP types
RequestShort: RequestShort
RequestShortArray: ckGenericArray
How comes the code below returns nothing ?
$res = $request->getParameter('$arrRequests');
$this->result = $res;

Answer 1

Seems to me that in:
$res = $request->getParameter('$arrRequests');
$this->result = $res;
return sfView::SUCCESS;
You misspelled the parameter for getParameter() function.
Perhaps it should be something like:
$res = $request->getParameterHolder()->getAll();
$this->result = $res;
return sfView::SUCCESS;
And don't forget to do a symfony cc && symfony webservice:generate-wsdl ... just in case.

Answer 2

It's because you are getting the wrong parameter.
$arrRequests != arrRequests
ckSoapParameterFilter already translate the #param $arrRequests to the simple parameter without the $ so you don't need it.
it should be:
public function executeUpdateRequests(sfWebRequest $request)
{
$res = $request->getParameter('arrRequests');
$this->result = $res;
return sfView::SUCCESS;
}
