PHP SoapClient Body Parameters are not being sent - php

Question

I am trying to make a SOAP call using the SoapClient within PHP but I am having trouble sending the body parameters. The headers are being sent over just fine and there are no errors but the body is empty.
I am not very familiar with PHP so this is new to me.
Here is my login function:
function Login($username, $password, $clientaccesskey, $useraccesskey)
{
$parameters = array(
'LogOnRequest' =>
array(
'ClientAccessKey' => $clientaccesskey,
'Password' => $password,
'UserAccessKey' => $useraccesskey,
'UserName' => $username
)
);
$headers = array();
$headers[] = new SoapHeader('http://www.w3.org/2005/08/addressing', 'Action', 'http://www.ultipro.com/dataservices/bidata/2/IBIDataService/LogOn');
$headers[] = new SoapHeader('http://www.w3.org/2005/08/addressing', 'To', 'https://service4.ultipro.com/services/BiDataService');
try
{
$soapclient = new SoapClient('https://service4.ultipro.com/services/BiDataService', array('soap_version' => SOAP_1_2, 'encoding' => 'UTF-8', 'exceptions' => TRUE, 'trace' => TRUE));
$soapclient->__setSoapHeaders($headers);
$response = $soapclient->__soapCall('LogOn', array($parameters));
echo json_encode($response);
echo htmlentities($soapclient->__getLastRequest());
}
catch(SoapFault $fault){
echo $fault->faultstring;
}
}
When I run this code it appears to be talking to the server because I am getting a response:
{"LogOnResult":{"ServiceId":null,"ClientAccessKey":null,"Token":null,"Status":"Failed","StatusMessage":"User authentication failed","InstanceKey":null}}
But this is the XML that is being sent to the service:
<?xml version="1.0" encoding="UTF-8"?>
<env:Envelope xmlns:env="http://www.w3.org/2003/05/soap-envelope" xmlns:ns1="http://www.ultipro.com/dataservices/bidata/2" xmlns:ns2="http://www.w3.org/2005/08/addressing">
<env:Header>
<ns2:Action>http://www.ultipro.com/dataservices/bidata/2/IBIDataService/LogOn</ns2:Action>
<ns2:To>https://service4.ultipro.com/services/BiDataService</ns2:To>
</env:Header>
<env:Body>
<ns1:LogOn />
</env:Body>
</env:Envelope>
This is what the XML is SUPPOSED to look like:
<?xml version="1.0" encoding="UTF-8"?>
<s:Envelope xmlns:s="http://www.w3.org/2003/05/soap-envelope" xmlns:a="http://www.w3.org/2005/08/addressing">
<s:Header>
<a:Action s:mustUnderstand="1">http://www.ultipro.com/dataservices/bidata/2/IBIDataService/LogOn</a:Action>
<a:To s:mustUnderstand="1">https://servicehost/services/BiDataService</a:To>
</s:Header>
<s:Body>
<LogOn xmlns="http://www.ultipro.com/dataservices/bidata/2">
<logOnRequest xmlns:i="http://www.w3.org/2001/XMLSchema-instance">
<UserName>username</UserName>
<Password>password</Password>
<ClientAccessKey>12345</ClientAccessKey>
<UserAccessKey>01234567890</UserAccessKey>
</logOnRequest>
</LogOn>
</s:Body>
</s:Envelope>
What am I doing wrong that is causing the body parameters to not be sent in the SOAP request?

Answer 1

I was able to achieve it using a class, the SOAPVar and the SOAPParam classes, like this:
function Login($username, $password, $clientaccesskey, $useraccesskey)
{
// Class handler for the request
class LogOnRequest {
function __construct($usr, $pwd, $cak, $uak)
{
$this->UserName = $usr;
$this->Password = $pwd;
$this->ClientAccessKey = $cak;
$this->UserAccessKey = $uak;
}
}
// Conversion to a SOAP object
$lor = new LogOnRequest($username, $password, $clientaccesskey, $useraccesskey);
$logOnRequest = new SoapVar($lor, SOAP_ENC_OBJECT, 'LogOnRequest', 'http://soapinterop.org/xsd');
$headers = array();
$headers[] = new SoapHeader('http://www.w3.org/2005/08/addressing', 'Action', 'http://www.ultipro.com/dataservices/bidata/2/IBIDataService/LogOn');
$headers[] = new SoapHeader('http://www.w3.org/2005/08/addressing', 'To', 'https://service4.ultipro.com/services/BiDataService');
try
{
$soapclient = new SoapClient('https://service4.ultipro.com/services/BiDataService', array('soap_version' => SOAP_1_2, 'encoding' => 'UTF-8', 'exceptions' => TRUE, 'trace' => TRUE));
$soapclient->__setSoapHeaders($headers);
// Direct call to the LogOn method and SOAP parameter pass
$response = $soapclient->LogOn(new SoapParam($logOnRequest, 'logOnRequest'));
echo json_encode($response);
echo htmlentities($soapclient->__getLastRequest());
}
catch(SoapFault $fault){
echo $fault->faultstring;
}
}
Which gave me the following XML request:
<env:Envelope xmlns:env="http://www.w3.org/2003/05/soap-envelope" xmlns:ns1="http://soapinterop.org/xsd" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:ns2="http://www.ultipro.com/dataservices/bidata/2" xmlns:ns3="http://www.w3.org/2005/08/addressing">
<env:Header>
<ns3:Action>http://www.ultipro.com/dataservices/bidata/2/IBIDataService/LogOn</ns3:Action>
<ns3:To>https://service4.ultipro.com/services/BiDataService</ns3:To>
</env:Header>
<env:Body>
<ns2:LogOn xsi:type="ns1:LogOnRequest">
<UserName>u</UserName>
<Password>p</Password>
<ClientAccessKey>cak</ClientAccessKey>
<UserAccessKey>uak</UserAccessKey>
</ns2:LogOn>
</env:Body>
</env:Envelope>
