hook de actualizacion Prestashop


Recommended Posts

Hola,

en los siguientes codigos tengo los hooks de prestashop que ayudan a enviar la actualizacion de un atributo  stock de skus, solo que al guardar el cambio nada sucede, la actualizacion no se aplica del otro lado donde he creado sincronizando los productos por el medio del mismo modulo.

 

linsync.php

require_once('classes/class.linapi.php');
require_once('classes/class.linproduct.php');

public function hookBackOfficeHeader()
    {
        if (Tools::getValue('module_name') == $this->name) {
            $this->context->controller->addJS($this->_path.'views/js/back.js');
            $this->context->controller->addCSS($this->_path.'views/css/back.css');
        }
    }


    public function hookActionProductAttributeUpdate($params)
    {
         ob_start();
        p($params);
        $content = ob_get_contents();
        file_put_contents('update-pr.txt', $content, FILE_APPEND);
        ob_end_clean();
    }

    public function hookActionUpdateQuantity($params)
    {
        if ($params['id_product_attribute']) {
            $idp = $params['id_product'];
            $ida = $params['id_product_attribute'];
            $api = new LinApi();
            $pr = new LinProduct($idp, false, Context::getContext()->language->id);

            $sku = $pr->getSku($ida);
            $xml = simplexml_load_string($api->getProductBySku(array($sku)));

            $qty = (int) $xml->Body->Products->Product->Quantity;
            $res = (int) $xml->Body->Products->Product->ReservedStock;
            $avl = StockAvailable::getQuantityAvailableByProduct($idp, $ida);
            if (($qty - $res) < $avl) {
                $api->updateProduct($pr->getXmlQty($ida));
            }
        }
    }

class.linapi.php

public function updateProduct($xml)
    {
        return $this->makeRequest('ProductUpdate', $xml);
    }

class.linproduct.php

public function getXmlQty($attribute = null)
    {
        $sku = (!$attribute || !$this->attributes) ? $this->reference : $this->attributes[$attribute]['reference'];
        $qty = StockAvailable::getQuantityAvailableByProduct($this->id, $attribute);
        $xml = '<?xml version="1.0" encoding="UTF-8" ?><Request><Product>';
        $xml .= $this->getXmlProperty('SellerSku', $sku);
        $xml .= $this->getXmlProperty('Quantity', $qty);
        $xml .= '</Product></Request>';
        return $xml;
    }

Gracias por su ayuda.
