Replacing Invoice Number With Order Reference

[DanAndrei]

Hi,

 

I am interested if I can replace the invoice no. with the order reference.

If yes, how?

 

Thanks!

Invoice number line has to be continuous, due to the law.

Yes, I understand but is it possible to make the change? If yes, how?

OK, I found that this must be the file that needs to be modified

HTMLTemplateInvoice.php

 

Can anyone give me a hint?

class HTMLTemplateInvoiceCore extends HTMLTemplate
{
	public $order;
	public $available_in_your_account = false;

	public function __construct(OrderInvoice $order_invoice, $smarty)
	{
		$this->order_invoice = $order_invoice;
		$this->order = new Order((int)$this->order_invoice->id_order);
		$this->smarty = $smarty;

		// header informations
		$this->date = Tools::displayDate($order_invoice->date_add);

		$id_lang = Context::getContext()->language->id;
		$this->title = HTMLTemplateInvoice::l('Invoice ').' #'.Configuration::get('PS_INVOICE_PREFIX', $id_lang, null, (int)$this->order->id_shop).sprintf('%06d', $order_invoice->number);
		// footer informations
		$this->shop = new Shop((int)$this->order->id_shop);
	}
