nuSoap Function is Not a Valid method - php

Question

When trying to instantiate my nuSoap method authenticateUser, it says:
Fatal error: Uncaught SoapFault exception: [Client] Function ("authenticateUser") is not a valid method for this service in /Applications/MAMP/htdocs/projo/dev/home.php:14
But when I replace that method name for one that already works, everything works just fine. So I think the instantiation syntax isn't wrong.
/*-----------
Authenticate User
------------*/
$server->register(
// method name
'authenticateUser',
// input parameters
array('sessionUserName' => 'xsd:string', 'sessionHash' => 'xsd:string', 'user' => 'xsd:string', 'pass' => 'xsd:string'),
// output parameters
array('return' => 'xsd:string'),
// namespace
$namespace,
// soapaction
$namespace . '#authenticateUser',
// style
'rpc',
// use
'encoded',
// documentation
'authenticates a user and returns a json array of the user info'
);
function authenticateUser($sessionUserName, $sessionHash, $user, $pass)
{
//Check to see if a countryCode was provided
if ($sessionUserName != '' && $sessionHash != '' && $user == $GLOBALS['wsUser'] && $pass == $GLOBALS['wsPass'])
{
$suid = 'AUTH'.$GLOBALS['guid'].'SESSION';
$database = new SQLDatabase();
$database->openConnection();
$database->selectDb();
//Query
$sql = "SELECT * FROM members WHERE member_email='" . $sessionUserName . "' LIMIT 1";
//Query MySQL
$return = $database->query($sql);
$userDetails = $database->fetch_array( $return );
if(!empty($userDetails)) {
$userDetails[0]['authSession'] = $suid;
$newArr = $userDetails[0];
$response = json_encode($newArr);
}
/*print $sql.'<br /><pre>';
print_r($response);
echo '</pre>';*/
//Throw SQL Errors
if (!mysql_query($sql))
{
die('Error: ' . mysql_error());
}
//Return on Success
return $response;
//Close Connection
mysql_close($con);
}
else
{
return 'Error: You must supply all of the inputs!x';
}
}
There are two things I can think of that would cause this error:
More likely: my registration of the function is somehow incorrect, even though the wsdl gui shows that the function is registered correctly and I've been able to successfully consume the method via the SoapUI program.
Less likely: somehow, the function isn't broken anymore, but its cached and so I'm seeing an old error.
The Question: When trying to consume this soap service method via PHP, why do I get an output error stating that this function doesn't exist in the service, when it clearly is?

Answer 1

Set
ini_set("soap.wsdl_cache_enabled", "0");
In every file you use soap from, or set wsdl_cache_enabled
to 0 in your php.ini file.
[soap]
; Enables or disables WSDL caching feature.
soap.wsdl_cache_enabled=0

Answer 2

If you are on Linux, you can also directly delete the cached wsdl file from /tmp/ dir

Answer 3

It was the CACHE!!! stupid. All I had to do was close my computer and go to bed. When I woke up, I ran the file again and it worked like a charm.
This is the second time this has happened with a function in a SOAP service.
Now I need to know how to clear the cache of a soap service. (nuSoap)
