I'm looking for a solution for automatic item number creation that will auto-create a reference number/code for any posted article, whatever the Node type. The purpose being that for any posted article (any Node type) that is created & posted by an author (with permission Roles authorised to post content) will have an item reference which can be traced throughout all aspects of workflow (including any Ticket Support document output - printer etc). This could quite simply be a standard item number as of that used on eBay (string of numbers) or similar used in organisational-wide portal. It might be for use in a local sales listing references (as in Gumtree), a vehicle listing platform (autotrader.co.uk) or simply to give a volumous document based content site a posting reference (internal intranet/external netsite), which for example, a 3rd party reader can jot down on paper, (email, cut and paste in Notes etc) and come back later and do a simple 'search' with the reference number, but not a 'purchase order' reference (as in Ubercart), purely for article reference purposes.
I'm not looking for anything tremendous (I'm not a PHPer (yet!) and I know this is more of a backend SQL DB but being more a Drupal 'plumber'/experimentalist I'm looking for simple solution for now that can be built upon later; something that Barcode module can also take advantage of and I can use in future projects of informational DataBases. Does anyone know of such a suitable solution/module for D7?
Any comments or How-tos welcome. Thanks.
