I've created a cronjob checking for EDI orders and creating them when one is there. The webshop has hikashop and hikamarket.

It all works like a charm, but there is one annoying side-effect. When creating the order from the cart in this cronjob, the order is created but the cart is not emptied so it seems.

The code is as below:

		$cart = new stdClass();
		$cart->user_id = $user_id;
		$cart->cart_shipping_address_ids = $shipping_address;

		// Save an entry to DB to be able to get cart_id
		$cartClass->save($cart);

		$cart_id = $cartClass->getCurrentCartId('cart');

		// Add all selected products at once
		$cartClass->addProduct($cart_id, $product_data);

		// Create basic order from cart
		$orderClass = hikashop_get('class.order');
		$order = $orderClass->createFromCart($cart_id);

		// Retrieve current order to update for custom fields
		$updateOrder = new stdClass();
		$updateOrder = $orderClass->get($order->order_id);

		// Update custom field date values
(...) // some extra code for custom fields and such

		// Save order with custom field values
		$orderClass->save($updateOrder);

Well, that makes perfectly sense. I had the assumption it would clear itself (silly perhaps?).

Thanks for the quick reply!
