I am having trouble getting a SOAP request out. I’m using generated client code that in turn uses SoapClient in WSDL mode. I can make the initial session start call, but when I make another call, the namespaces appear to be out of whack.

Here is the SOAP request from SoapUI that works:

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:wsdl="http://vendor_uri/">
   <soapenv:Header/>
   <soapenv:Body>
      <wsdl:GetProducts>
         <GetProductsRequest>
            <UserInfo Token="XXXXX"/>
            <ClientReferenceData Service="pinless_dialing"/>
         </GetProductsRequest>
      </wsdl:GetProducts>
   </soapenv:Body>
</soapenv:Envelope>

And here’s the XML request generated by SoapClient (via Wireshark):

<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ns1="" xmlns:ns2="http://vendor_uri/">
    <SOAP-ENV:Body>
        <ns2:GetProducts>
            <GetProductsRequest>
                <ns1:UserInfo Token="XXXXX"/>
                <ns1:ClientReferenceData Service="pinless_dialing"/>
            </GetProductsRequest>
        </ns2:GetProducts>
    </SOAP-ENV:Body>
</SOAP-ENV:Envelope>

The problem appears to be in the ns1 namespace. If I take that same request, and strip out that namespace, the call goes through SoapUI without a hitch.

Again, this is being generated by SoapClient pretty much directly. Here’s the relevant code from the generated code:

class B2BServiceSoapClient{
    /**
     * The WSDL URI
     *
     * @var string
     */
    public static $_WsdlUri='http://vendor_wsdl_uri';
    /**
     * The PHP SoapClient object
     *
     * @var object
     */
    public static $_Server=null;

    /**
     * Send a SOAP request to the server
     *
     * @param string $method The method name
     * @param array $param The parameters
     * @return mixed The server response
     */
    public static function _Call($method,$param){
        if(is_null(self::$_Server))
            self::$_Server=new SoapClient(self::$_WsdlUri);
        return self::$_Server->__soapCall($method,$param);
    }

The rest of the class consists of type definitions to mirror the WSDL.

Here is the code I use to exercise the class:

<pre>
<?php
ini_set('soap.wsdl_cache_enabled',0);

require_once('BossILDClient.php');

$client = new B2BServiceSoapClient();
$sessionToken = new UserInfoType();
$parameters = new SessionStart();
$parameters->UserInfo = new UserInfoType();
$parameters->UserInfo->UserName = 'username';
$parameters->UserInfo->Password = 'password';

echo "Calling SessionStart(" . print_r($parameters, true) . ")" . PHP_EOL . PHP_EOL;

$result = $client->SessionStart($parameters);
$sessionToken->Token = $result->SessionStartResponse->Result->Token; 

echo "REQUEST HEADER:\n" . htmlentities(B2BServiceSoapClient::$_Server->__getLastRequestHeaders()) . "\n";
echo "REQUEST:\n" . htmlentities(B2BServiceSoapClient::$_Server->__getLastRequest()) . "\n";
echo "RESPONSE HEADER:\n" . htmlentities(B2BServiceSoapClient::$_Server->__getLastResponseHeaders()) . "\n";
echo "RESPONSE:\n" . htmlentities(B2BServiceSoapClient::$_Server->__getLastResponse()) . "\n";

$getProducts = new GetProducts();
$getProducts->GetProductsRequest = new GetProductsRequestType();
$getProducts->GetProductsRequest->ClientReferenceData = new ClientReferenceDataType();
$getProducts->GetProductsRequest->ClientReferenceData->Service = 'pinless_dialing';
$getProducts->GetProductsRequest->UserInfo = $sessionToken;

echo "Calling GetProducts(" . print_r($getProducts, true) . ")" . PHP_EOL . PHP_EOL;

try {
    $result = $client->GetProducts($getProducts);
} catch(SoapFault $sf) {
    echo "SOAP Fault error!!!" . PHP_EOL . PHP_EOL;
}

echo "REQUEST HEADER:\n" . htmlentities(B2BServiceSoapClient::$_Server->__getLastRequestHeaders()) . "\n";
echo "REQUEST:\n" . htmlentities(B2BServiceSoapClient::$_Server->__getLastRequest()) . "\n";
echo "RESPONSE HEADER:\n" . htmlentities(B2BServiceSoapClient::$_Server->__getLastResponseHeaders()) . "\n";
echo "RESPONSE:\n" . htmlentities(B2BServiceSoapClient::$_Server->__getLastResponse()) . "\n";
?>
</pre>

I have exhausted my wild guesses and considered thoughts to no avail. How can I prevent that “inner” namespace?

Here’s the direct output from the code above:

My guess is that SoapClient is confused because it sees elementFormDefault="qualified" but no namespace on the schema. Save the WSDL to your local machine and try making everything part of the first <xsd:schema> element in the WSDL by removing all the:

</s:schema>
<s:schema elementFormDefault="qualified">

After that pass your local WSDL to SoapClient. The endpoint in the WSDL should be enough to tell it where to send the message.
