Prestashop 1.6 : External script to add stock movement

[tom29]

Hello, I'm writting an external script to add stock movements to Prestashop using the addProduct function of the StockManagerCore class. I'm using Prestashop 1.6.1.17. <?php include(dirname(__FILE__).'/../config/config.inc.php'); include(dirname(__FILE__) . '/../init.php'); $id_warehouse = 1; $id_product = 1; $id_product_attribute = 3; $warehouse = new Warehouse($id_warehouse); $quantity = 10; $id_stock_mvt_reason = 3; $price_te = 1.0; $employee = 10; $stock_manager = StockManagerFactory::getManager(); if ($stock_manager->addProduct($id_product, $id_product_attribute, $warehouse, $quantity, $id_stock_mvt_reason, $price_te, true, $employee)) { echo " It works! "; StockAvailable::synchronize($id_product); } else { echo " It doesn't work! "; } ?> I don't understand why the method addProduct doesn't work. I have none the messages "It Works" or "It doesn't work", except if I put a nonexistent warehouse, in this case I have the "It doesn't work" message. I can use successfully other methods of the class as getProductPhysicalQuantities for example. Anyone has an idea of what is wrong? Thanks, Thomas
