Returning An Array of Objects in PHP Web Service

Question

I want to return an array of article objects in a PHP web service, using nuSOAP v 1.114. This is how I set up the WSDL:

$server->wsdl->addComplexType(         


        

Answer 1

I fixed this error. For anyone interested, this seems to be a bug in NuSOAP. You MUST register your returnType for the function as xsd:Array for it to correctly return the array, even though correct WSDL would constitute it as 'tns:ArrayOfArticleType'. I found this in some Drupal source code:

// Set return value for the service
$return = array();
if ($method['#return']) {
  **// Don't let a struct be declared as return parameter, because nusoap will not
  // Send back anything.**
  $return['return'] = 'xsd:'. $method['#return'];
  if ($method['#return'] == 'struct' || $method['#return'] == 'array') {
    $return['return'] = 'xsd:Array';
  }
} 

Hope this helps someone else who struggled with the same problem.
