Webservice edit customer PS 1.6 : namespace error

[T.Baron]

Bonjour à tous,

 

J'ai mis en place un script qui, via les webservices de Prestashop, viendrait mettre à jour le mot de passe d'un client.

C'est une requête en POST qui récupère le client via son adresse email. Le problème c'est qu'il n'arrive pas à mettre à jour le mot de passe, il s'arrête juste avant et me retourne plusieurs erreurs du genre :

[PHP Warning #2] SimpleXMLElement::__construct(): namespace error : Namespace prefix xlink for href on id_default_group is not defined (/home/XXX/site/classes/webservice/WebserviceRequest.php, line 1374)]

 

J'ai beau relire mon code, impossible de trouver ce qui pourrait coincer. J'ai d'autres utilisations des webservices sur ce site qui fonctionnent très bien (création de client par exemple).

 

Le code PHP :

<?php
define('DEBUG', true);
define('PS_SHOP_PATH', 'XXXXXXXXX');
define('PS_WS_AUTH_KEY', 'XXXXXXXX');
require_once('./PSWebServiceLibrary.php');
require_once('./Encrypt.php');

$email=$_POST['email'];
$decrypted=$mcrypt->decrypt($_POST['passwd']);
$passwd=$decrypted;

try
{
$webService = new PrestaShopWebservice(PS_SHOP_PATH, PS_WS_AUTH_KEY, DEBUG);

$filter = array(
    'email' => $email
);

$opt = array(
    'resource' => 'customers',
    'display' => 'full',
    'filter' => $filter
);

$xml = $webService->get($opt);

$resources = $xml->children()->children();

$customer_id = $resources->customer->id; 

$resources->customer->passwd = $passwd; 

// Appel du web service

    $opt = array('resource' => 'customers');
    $opt['putXml'] = $xml->children()->asXML(); 
    $opt['id'] = $customer_id;
    $xml = $webService->edit($opt);
    		
    echo "Successfully updated";
}
catch (PrestaShopWebserviceException $ex)
{
    $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();
}
?>

 

 

L'erreur retournée :

Une idée ?

I manage to resolve this issue.

The solution is to add the namespace to the outest element of the XML you send on edit() call.

So instead of:

<customers> 
  <customer> 
    ... 
  </customer> 
</customers>

You need to send:

<customers xmlns:xlink="http://www.w3.org/1999/xlink"> 
  <customer> 
    ... 
  </customer> 
</customers>

If you activate the debug, you will see this namespace added to the <prestashop> XML node, but when you do: 

 $opt['putXml'] = $xml->children()->asXML(); 

you are loosing this external node with the namespace reference.
