Fatal error: Call to a member function __setSoapHeaders() when generating access token in php

Question

When trying to generate a soap access token for salsforce I am getting an error:

Fatal error: Call to a member function __setSoapHeaders() on a non-object in D:\XAMPP\htdocs\test24\soapclient\SforceBaseClient.php on line 158

I'm not sure how to solve this.

  

     require ('config.php');
     ini_set('soap.wsdl_cache_enabled', 0);
     ini_set('soap.wsdl_cache_ttl', 0);

     //Create a new Salesforce Partner object
     $connection = new SforcePartnerClient();


 //Create the SOAP connection to Salesforce
 try {
  $connection->createConnection(salesforce_wsdl);
 } catch (Exception $e) {
    //Salesforce could be down, or you have an error in configuration
  //Check your WSDL path
  //Otherwise, handle this exception
 }

 //Pass login details to Salesforce
 try {
  $connection->login(salesforce_username, salesforce_password.salesforce_token);
 } catch (Exception $e) {
  //Make sure your username and password is correct
  //Otherwise, handle this exception
 }

 //Describing the Leads object and printing the array
     $describe = $connection->describeSObjects(array('Lead'));
     print_r($describe);

     //Create New Lead
     $leadFirstName = "Ahmed";
     $leadLastName = "Dirie";
     $leadCompany = "Pick Yours Up";
     $leadEmail = "adirie@pickyoursup.com";

     //Creating the Lead Object
     $lead = new stdClass;
     $lead->type = 'Lead';
     $lead->fields = array(
          'FirstName' => $leadFirstName,
          'LastName' => $leadLastName,
          'Company' => $leadCompany,
          'Email' => $leadEmail
     );

     //Submitting the Lead to Salesforce
     $result = $connection->create(array($lead), 'Lead');
?>

If you open the file soapclient\SforceBaseClient.php and go to line # 158 you will realalize that it is setting the headers there.

the code there will be something like.

$this->sforce->__setSoapHeaders(array($this->XXXXXXX));

What it is doing is its setting header using $this->sforce and by looking at error it seems like $this->sforce is non-object.

When we back trace, we find its setting the value of $this->sforce in createConnection() function in SforceBaseClient.php

I would suggest you to place echo and var dump to see when its setting that object and when its getting reset to null.

If its confusing for you then you can try and use different (older or newer) version of this toolkit. Generally this work just fine.
