[SalesForce] Element {} item is invalid Can anyone explain this error

When we are connecting to sfdc from php using the SOAP API we are receiving an error message: Element {} item is invalid How can i resolve my issuse

ini_set("soap.wsdl_cache_enabled", "0");
ini_set(E_ALL,1);
ini_set('display_errors',1);


// Include the PHP Toolkit
require_once('salesforceAPI/soapclient/SforcePartnerClient.php');
require_once('salesforceAPI/soapclient/SforceHeaderOptions.php');

// Login
define('USER','xxxxx@sfdc.com');
define('PASSWORD', 'yyyyyyyy');
define('SECURITY_KEY', 'zzzzzzzzzzzzzzz');

//echo userName;
//echo password;
//echo securitytoken;

$sfdc = new SforcePartnerClient();
$SoapClient = $sfdc->createConnection('salesforceAPI/partner.wsdl.xml');

$loginResult = false;

try {
    // log in with username, password and security token if required
   $loginResult = $sfdc->login(USER, PASSWORD . SECURITY_KEY);
} catch (Exception $e) {
    global $errors;
    $errors = $e->faultstring;
    echo "Fatal Login Error <b>" . $errors . "</b>";
    die;
}

// Define constants for the web service. We'll use these later
$parsedURL = parse_url($sfdc->getLocation());
define ("_SFDC_SERVER_", substr($parsedURL['host'],0,strpos($parsedURL['host'], '.')));
define ("_WS_NAME_", 'salesforceAPI/Ctest');
define ("_WS_WSDL_", _WS_NAME_ . '.xml');
define ("_WS_ENDPOINT_", 'https://' . _SFDC_SERVER_ . '.salesforce.com/services/wsdl/class/' . _WS_NAME_);
define ("_WS_NAMESPACE_", 'http://soap.sforce.com/schemas/class/' . _WS_NAME_);

$client = new SoapClient(_WS_WSDL_);
$sforce_header = new SoapHeader(_WS_NAMESPACE_, "SessionHeader", array("sessionId" => $sfdc->getSessionId()));
$client->__setSoapHeaders(array($sforce_header));

$method = $client->__getFunctions();
echo _SFDC_SERVER_."<br>";
echo _WS_NAME_."<br>";
echo _WS_WSDL_."<br>";
echo _WS_ENDPOINT_."<br>";
echo _WS_NAMESPACE_."<br>";
//
try {

    $wsParams=array('name' =>'hhhi');
    // call the web service via post
    $client->cInsert($wsParams);

// this is really bad.
} catch (Exception $e) {
    global $errors;
    $errors = $e->faultstring;
    echo "Ooop! Error: <b>" . $errors . "</b>";
    die;
}

The web service class in question is:

global class Ctest {
  // Request Class
  global class RequestClass {
    webservice String accName;
    //webservice String accNum;
  }
  // Response
  Class global class ResponseClass {
    webservice String acName;
  }

  // webservice
  static ResponseClass cInsert(RequestClass req) {
    ResponseClass res = new ResponseClass();
    Account a = new Account();
    a.Name = req.accName;
    insert a;
    res.acName = a.Name;
    return res;
  }
}

Best Answer

Is it possibly because in your php class, you are setting up the web service call with

$wsParams=array('name' =>'hhhi');

but your request class parameter is called accName, when you then try to extract it with 

a.Name = req.accName;

It's been a long time since I worked with PHP.
