Question

I want to call a webservice using Zend_Soap_Client. This is the relevant code:

    $params = new stdClass();
    $params->transactionId = $transactionId;
    $params->transactionState = $transactionState;
    $params->details = $transactionDetails;
    var_dump($params->details);
    try {
        $this->_soapClient->updateTransaction($params);
    }

The problem is with the details parameter, which is a complex type in the WSDL. $transactionDetails contains an array with the (non-empty) elements of the complex type, and this is visible in the var_dump(). Previously, I tried using a PHP class with the elements as properties. In both cases, what the SOAP client actually sends is this:

<SOAP-ENV:Body>
    <ns1:UpdateTransactionRequest>
        <transactionId>45</transactionId>
        <transactionState>SUCCESS</transactionState>
        <details/>
    </ns1:UpdateTransactionRequest>
</SOAP-ENV:Body>

What am I doing wrong?

UPDATE: I think the cause of the problem is that the complexType declared for the parmeter is a base type, of which several extension types exist in the WSDL, and I want to use one of those extension types. I guess Zend_Soap_Client does not recognize any elements that are not present in the base type, which is all of them. Is there a way around this?

The solution lies in the standard PHP SOAP client, which Zend_Soap_Client extends. The SoapVar class allows you to wrap a parameter and specify the actual type to use. What I had to do is go back to using a PHP class for $transactionDetails and this code:

$params->details = new SoapVar($transactionDetails, 
    SOAP_ENC_OBJECT, get_class($transactionDetails), $namespace);
