Drupal Serial Number

Question

I'm new to drupal, had a good start with basic functionality but I need to do some specific tasks and I'm starting to struggle.

I want a form with a drop down list, that selects a string. I also want to create a serial number thats unique, and append it to the string.

I was thinking that I'd create a document type "index", then as as document of type index was created increment the number. I don't know how to create the number in the data base so that its not always reset each time the data base starts.

Can anyone point me in the right direction.

I looked at the serial module but this causes my module install to role out with error, I need to disable the module to restore the site.

This should give you what you need:

Answer 2

I would build something like that with the computed field module. It allows you to take values from your node form, process them with php and save it to your database as a separate CCK field.
