PHP SoapServer always calls the same function despite calling different ones

Question

My SOAP server is (intended to be) setup with three operations: login, logout, and version.

The login function's code is currently "faking" it at the moment, accepting two parameters, a username and password, automatically "authenticating" them by storing them in the function class' private username and password variables. I have a session started at the entry point of the web service action, and when setting the function class in the SoapServer during initialization, I'm persisting connections as follows:

       $this->setClass('WebSvcSoapFunctions');
       $this->setPersistence(SOAP_PERSISTENCE_SESSION);

When I create a SOAP CLIENT and call my service, regardless of which function is called, it appears that the version() function is always executed rather than the one called. I imagine this is probably due to the way my WSDL is written, but I can't see a problem (i'm new)....

I have the following WSDL listening via a PHP SoapServer:

<?xml version="1.0" encoding="UTF-8"?>

My SOAP function class is as follows (included in my SOapServer via setClass()):

My SOAP CLIENT test class is as follows:

ini_set("soap.wsdl_cache_enabled", "0");  
define('WSDL_URL','http://soap.jrimer-amp64/?wsdl');   
try
{ 
    $client = new SoapClient(WSDL_URL, array('trace'=>true));

    $request = 'version';
    $args = array();
    $SOAPResult = $client->$request($args); // call the SOAP Server's "version" function
    OutputLastRequestResponse($client, $request, $args, $SOAPResult);

Any ideas what's going on?

NOTE: I notice that if I simply comment out the definition in the WSDL for the VERSION function that the next defined function becomes the "always called" function (login)... What do I have configured wrong in that WSDL?

Was it helpful?

Solution

Yeah, it was the WSDL, I completely have it misdefined... Restructured the WSDL and it fields requests correctly now...
