I found a thread where someone was asking if it's possible to have sequential numbering on the invoice. I customized a bit my invoice but I want to add sequential numbering on it. I also found this on the docs: http://www.amember.com/docs/How_to_set_up_custom_invoice_numbering I've done that but my invoices show up exactly the same. I would like to know if I have to modify /library/Am/Pdf/invoice.php and include something there in order to show the numbering. Also I would like to know if someone could help me set the invoice count and start from 0 and have like 6 or 9 digits for the invoice. I want to display the invoice number on the PDF file just like the invoice ID I attached a screenshot for more details. Spanish laws require me to have sequential invoice numbers and I don't know how to do it.
My bad, the code found on the docs actually works but only for new invoices which is ok for me. All I needed to do is change: Code: $invoice->public_id = date('Y_m_') to Code: $invoice->public_id = date('Y-') so the code renders like this: 2013-1. 2013-2. 2013-3 etc, but only for new invoices. This code will be rendered by $invoice->public_id which is located inside amember/library/Am/Pdf/invoice.php So instead of having an invoice ID like: Invoice: 7C3ME you will have something like: Invoice: 2013-1 Hope this helps someone out there
