SoapClient not serializing attributes of child classes

[datWeazel]

Describe the bug
I got a generated class ArrayOfBasketItem which in turn got an array of BasketItem objects.
BasketItem is a base class for different types of items. One of those is ExpositionPeriodReservation.

I created a new ArrayOfBasketItem with one ExpositionPeriodReservation and tried to send it via the Soap Client to the service.

BasketItem provides some attributes like id and quantity. ExpositionPeriodReservation got additional parameters like expositionId, expositionPeriodId and more.

$myExpositionPeriodReservation = new ExpositionPeriodReservation(...);
$parameters = new ArrayOfBasketItem([$myExpositionPeriodReservation]);
$this->setResult($resultLockBasketItems = $this->getSoapClient()->__soapCall('LockBasketItems', [
                $parameters,
            ], [], [], $this->outputHeaders));

The generated XML (in __getLastRequest) looks like this:

<?xml version="1.0" encoding="UTF-8"?>
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"
    xmlns:ns1="http://www.xxx.be/webshop/"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
    <SOAP-ENV:Header />
    <SOAP-ENV:Body>
        <ns1:LockBasketItemsRequest>
            <ns1:BasketItems>
                <ns1:BasketItem>
                    <ns1:Id>3f717c96-2200-424d-b987-2b9bf58c1357</ns1:Id>
                    <ns1:Quantity>1</ns1:Quantity>
                    <ns1:RuleNamesToIgnore xsi:nil="true" />
                </ns1:BasketItem>
            </ns1:BasketItems>
            <ns1:Context>
                <ns1:ShopId>xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx</ns1:ShopId>
                <ns1:Password>xxxxx</ns1:Password>
            </ns1:Context>
        </ns1:LockBasketItemsRequest>
    </SOAP-ENV:Body>
</SOAP-ENV:Envelope>

So it is missing all of the attributes of the ExpositionPeriodReservation and only got the attributes of BasketItem.

I uploaded the BasketItem and ExpositionPeriodReservation class files as well as the generated client file for the method I try to use:

BasketItem.txt
ExpositionPeriodReservation.txt
Lock.txt

This is the full object that's in $parameters of the __soapCall: (There's another object of type LockBasketItemsRequest around it, but that's irrelevant for the problem.

Hi,
This is possibly due to the native PHP SoapClient class that does not map all the attributes from the ExpositionPeriodReservation to an XML structure.
Is the ExpositionPeriodReservation indeed defined in the WSDL?
You'll probably have to override the SoapClient class, as I did at https://github.com/WsdlToPhp/PackageEws365, in order to alter the XML before it is actually sent. You'll have to check the Parameter instance type in order to map the PHP class properties to their XML tag.
Let me know anyway

[datWeazel]

Yes, the ExpositionPeriodReservation is defined in the WSDL. All classes I used are completely auto generated.
Is there a way to tell the SoapClient class that ExpositionPeriodReservation is a subclass of BasketItem so it serializes correctly without me having to construct the XML completely by hand?

This is the definition of ExpositionPeriodReservationin the XML.

<xs:complexType name="ExpositionPeriodReservation">
    <xs:complexContent mixed="false">

The SoapClient does not seem to care and you can't indicate anything more from my point of view.

You don't have to construct the XML completely but you can complete it by overriding the __doRequest as in the given sample project, using for exemple a DOMDocument object and then targeting the right DOMElement in order to add what's missing. Be aware that you can catch the original PHP Object that has to be sent by overriding the __call method which receives the PHP Object you constructed. So, storing it as a property in you overridden SoapClient, you can use it after in the __doRequest method.
