Order reference as invoice number

[SmartyLo]

Hello, In my shop order reference consists of only numbers, and I need that order invoice number would be totaly same as order reference number. I found where invoice number generating, but it's complicated to replace it with other value.

Here what I have in OrderInvoice.php file:

public function getInvoiceNumberFormatted($id_lang, $id_shop = null)
    {
        $invoice_formatted_number = Hook::exec('actionInvoiceNumberFormatted', array(
            get_class($this) => $this,
            'id_lang' => (int)$id_lang,
            'id_shop' => (int)$id_shop,
            'number' => (int)$this->number
        ));

        if (!empty($invoice_formatted_number)) {
            return $invoice_formatted_number;
        }

        $format = '%1$s%2$06d';

        if (Configuration::get('PS_INVOICE_USE_YEAR')) {
            $format = Configuration::get('PS_INVOICE_YEAR_POS') ? '%1$s%3$s/%2$06d' : '%1$s%2$06d/%3$s';
        }

        return sprintf($format, Configuration::get('PS_INVOICE_PREFIX', (int)$id_lang, null, (int)$id_shop), $this->number, date('Y', strtotime($this->date_add)));
    }

Thanks.

I tried to paste this code into return value

like this:

 return sprintf($format, Configuration::get(.$order->id.'#'.$order->reference;);

It doesnt work, but it caused other problem - I submitted new order, it returned 500 error page, but was done and I can see it on backoffice. And now I cant apply order state filters anymore (the state of this order was 0, in phpmyadmin I replaced it to 3 - normal value, but there is still no any filters. What I have to do? I am in panic, because it wasnt "testing: shop.

I replaced back OrderInvoice.php, but filters are still unavailable.

Please, help.

No, you need to use one of them.

return sprintf($format, $order->id);   //or

Or

return sprintf($format,$order->reference);

It's not configuration value and you have errors in your statement.

Thank you for promt reply!

Well, such code doesnt work - name of invoice file is still incrementing value(+1 to previous values, but reference number is much bigger now), and in invoice file it doenst display invoice number now, there is white space.

Is the "$order->reference" global variable?
