Change in Invoice.php to change pdf title

[rishabhchd19]

I have changed

      $path .= preg_replace('/[^A-Za-z0-9_\-\.]/', '_', 'order'.$layout.'_'.$invoiceNumber.'.pdf');
      //$path .= shopFunctionsF::getInvoiceName($invoiceNumber, $layout).'.pdf';

Before it was:

      //$path .= preg_replace('/[^A-Za-z0-9_\-\.]/', '_', 'order'.$layout.'_'.$invoiceNumber.'.pdf');
      $path .= shopFunctionsF::getInvoiceName($invoiceNumber, $layout).'.pdf';

why it was put to comment $path .= shopFunctionsF::getInvoiceName($invoiceNumber, $layout).'.pdf';  ?
The changes i have made gonna make problems? What was the reason behind making first line as a comment?

If i keep the first line under comment, then how can I change title of pdf from VMINVOICE to ORDERINVOICE with the second line?

Hello

Do an overwrite of the key COM_VIRTUEMART_FILEPREFIX_INVOICE , and it should work without having to hack the code which is a very bad idea.
