Is there a module which allows to set expiry date on fields on content type. Needed when we want a particular field to be expired after a given interval of time, not the complete node as in case of node expire module.
First feature of Node expire is:
- Perform custom actions when the nodes expire
Just write a custom action that will change field's value instead of unpublishing node.
As far as I know there is no such module. But since Node Expire integrates with rules, I could imagine that you can configure the node to expire without unpublishing it and then react on the expiration by setting the field value of the field(s) in question to empty.
