How to generate delivery pdfs based on ids instead of date?

[Hasher]

AdminPdfController.php:

	public function processGenerateDeliverySlipsPDF()
	{
		$order_invoice_collection = OrderInvoice::getByDeliveryDateInterval(Tools::getValue('date_from'), Tools::getValue('date_to'));

		if (!count($order_invoice_collection))
			die(Tools::displayError('No invoice was found.'));

		$this->generatePDF($order_invoice_collection, PDF::TEMPLATE_DELIVERY_SLIP);
	}

How can I modify this to generate pdfs based on order's ids instead of dates?

Create your own method - OrderInvoice::getByIdInterval - and call it in processGenerateDeliverySlipsPDF().
