Get price via API for customized data


Recommended Posts

Greetings

I'm creating a module for the specific product. I'm using text customization, and want to add a product with customization into cart via my module. I've already done with product adding to a cart, and now need to calculate a price for customization. I need to ask 3d party API to calculate a price for customization. Off course I can change ps_customized_data.price directly in DB or use override, but I would like to know if there's a better way?

My current code to add item into cart:

$this->context->cart->addTextFieldToProduct(
            $product->id,
            $customizationFieldId,
            Product::CUSTOMIZE_TEXTFIELD,
            $pathData['name']
        );

        $exising_customization = Db::getInstance()->executeS('SELECT id_customization FROM ' . _DB_PREFIX_ . 'customized_data ORDER BY id_customization DESC LIMIT 0,1');
        $customization = $exising_customization[0]['id_customization'];
        $cart->updateQty(
            1,
            $product->id,
            null,
            $customization,
            'up'
        );

        die(json_encode([
            'result' => $cart->update()
        ]));

addTextFieldToProduct does not allow me to control price, and I do not see some entity to control those DB data. Also in updateQty I would like to have 'equal' operator, cause I need only 1 item per customization, but not so crucial.

Also as I've understood I can't change info inside hooks, right? $data in Hook::exec($name, $data) is not passed by pointer. I think good points to calculate price  are  actionCartUpdateQuantityBefore or actionCartSave.

$customization = $exising_customization[0]['id_customization'];
        Db::getInstance()->execute(
            'UPDATE `' . _DB_PREFIX_ . 'customized_data`
                    SET `price` = ' . $pathData['price'] . '
                    WHERE `id_customization` = ' . (int)$customization . '
                    AND `value` = "' . $pathData['name'] . '"'
        );
        $cart->updateQty(
            1,
            $product->id,
            null,
            $customization,
            'up'
        );

 

solved via DB, looks as this code work for me, but will be happy if someone adds better solution
