Prestashop 1.5 Webservice Updating Customer id_default_group PHP - web-services

Question

I need to automatically update the prestashop->customers->customer->id_default_group value using PHP via the Prestashop webservice. The script knows the new value and it is done before/as the page loads.
I can get a customer record, or I can get just the "id_default_group" of a customer record but I run into trouble when I try changing the record value and updating the webservice. I get back "HTTP/1.1 400 Bad Request".
It seems like I am incorrectly trying to update the xml or object.
It would be preferable to do all this by only getting and updating the "id_default_group" and not having to retrieve the complete customer record.
I have:
define('DEBUG', true);
define('PS_SHOP_PATH', 'http://www.site.com/');
define('PS_WS_AUTH_KEY', 'yuyiu');
require_once('../PSWebServiceLibrary.php');
// First : We always get the customer's list or a specific one
try
{
$webService = new PrestaShopWebservice(PS_SHOP_PATH, PS_WS_AUTH_KEY, DEBUG);
$opt = array('resource' => 'customers'); // Full customer record
//$opt = array('resource'=>'customers','display'=> '[id_default_group]','filter[id]' => '['.$_SESSION["iemIdCustomer"].']'); // Customer id_default_group value
if (isset($_SESSION['iemIdCustomer'])){
$opt['id'] = $_SESSION['iemIdCustomer'];
}
$xml = $webService->get($opt);
// The elements from children
$resources = $xml->children()->children();
// $resources = $xml->children()->children()->children(); // If just getting id_default_group
}
catch (PrestaShopWebserviceException $e)
{
// Here we are dealing with errors
$trace = $e->getTrace();
if ($trace[0]['args'][0] == 404) echo 'Bad ID';
else if ($trace[0]['args'][0] == 401) echo 'Bad auth key';
else echo 'Other error';
}
// Second : We update the data and send it to the web service
if (isset($_SESSION['iemIdCustomer'])){
// Update XML with new values
$xml->customers->customer->id_default_group = 4;
//$resources = $xml->children()->children()->children();
// And call the web service
try
{
$opt = array('resource' => 'customers');
//$opt = array('resource'=>'customers','display'=> '[id_default_group]','filter[id]' => '['.$_SESSION["iemIdCustomer"].']');
$opt['putXml'] = $xml->asXML();
$opt['id'] = $_SESSION['iemIdCustomer'];
//$opt['display'] = 'id_default_group';
$xml = $webService->edit($opt);
// if WebService succeeds
echo "Successfully updated.";
}
catch (PrestaShopWebserviceException $ex)
{
// Dealing with errors
$trace = $ex->getTrace();
if ($trace[0]['args'][0] == 404) echo 'Bad ID';
else if ($trace[0]['args'][0] == 401) echo 'Bad auth key';
else echo 'Other error<br />'.$ex->getMessage();
}
}
This is basic for those in the know so I hope you can help.
Thanks in advance,
Lance

Ok I go the following to work.
The following line seem to do the trick:
$xml->children()->children()->id_default_group = 4;
Follows is the line with the rest of the code to do the task.
// Get the customer's id_default_group
try
{
$webService = new PrestaShopWebservice(PS_SHOP_PATH, PS_WS_AUTH_KEY, DEBUG);
$opt = array('resource' => 'customers');
$opt['id'] = $_SESSION["iemIdCustomer"];
$xml = $webService->get($opt);
// Get the elements from children of customer
$resources = $xml->children()->children()->children();
}
catch (PrestaShopWebserviceException $e)
{
// Here we are dealing with errors
$trace = $e->getTrace();
if ($trace[0]['args'][0] == 404) echo 'Bad ID';
else if ($trace[0]['args'][0] == 401) echo 'Bad auth key';
else echo 'Other error';
}
// Update the data and send it to the web service
// Update XML with new value
$xml->children()->children()->id_default_group = 4;
// And call the web service
try
{
$opt = array('resource' => 'customers');
//$opt = array('resource'=>'customers','display'=> '[id_default_group]','filter[id]' => '['.$_SESSION["iemIdCustomer"].']');
$opt['putXml'] = $xml->asXML();
$opt['id'] = $_SESSION['iemIdCustomer'];
//$opt['display'] = 'id_default_group';
$xml = $webService->edit($opt);
// if WebService don't throw an exception the action worked well and we don't show the following message
echo "Successfully updated.";
}
catch (PrestaShopWebserviceException $ex)
{
// Here we are dealing with errors
$trace = $ex->getTrace();
if ($trace[0]['args'][0] == 404) echo 'Bad ID';
else if ($trace[0]['args'][0] == 401) echo 'Bad auth key';
else echo 'Other error<br />'.$ex->getMessage();
}
Hope that it assists someone.

i think you have this error because you are editing the bad node ;)
try with
$xml->customer->id_default_group = 4;
That should be OK :)
