Adding Products in Prestashop 1.5.5 via Web-Services

[UnaLogica]

Hello, this is my first topic here.

i know it's a question that has been already asked a lot of times but even with the search function and reading some guides i can't resolve the problem.

I'm tring to add a product via web-service using some samples founded here in the forum but i still get an error: 

 

The code is this one: 

 

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

$opt = array('resource' => 'products');

$xml = $webService->get(array('url' => PS_SHOP_PATH.'/api/products?schema=synopsis'));

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

 

unset($resources->position_in_category);

unset($resources->manufacturer_name);

 

$resources->price = '1000';

$resources->active = '1';

$resources->quantity = '50';

$resources->link_rewrite = 'blabla';

$resources->name = 'blabla';

 

$description='<b>ceci est un nouveau test en gras</b>';

$node= dom_import_simplexml($resources->description->language[0][0]);

$no = $node->ownerDocument;

$node->appendChild($no->createCDATASection($description));

 

$resources->description_short = 'blabla';

$resources->associations = '';

 

$opt = array('resource' => 'products');

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

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

 

thanks in advance
