- you just have to do a little php code ie $payDate = $invoice[date] + 14; then assign a smarty variable to it and then edit the template to add a new line in to show it - hope this makes sense - note above code isn't 100% correct - just a guide for you
The smarty variable I think I put in invoice.php and the new line in template.tpl But where do I put the php code?
i've never put in payment date as as far as im concerned as soon as i write up the invoice and email it - its now payable and due - none of this due in 30 days nonsense :)
but i will think about this and add it to the roadmap
