I want to set a unique 7-digit code to a custom content type and display it in a disabled textfield when a node is created. I created a CCK textfield and set it to disabled in hook_form_alter, great.
I think that a good way to make this unique ID is just to use the node id and fill it out to the required length (eg. 0000012). It doesn't look like $nid is available at the node/add form though. How can I set this ID field to default to the
$nid? Can I access the
hook_form_alter() as the content is created (on form submission)?
