Ad expiration by category
Hello,
Searched around and have found related threads but non that actually post the answer to the question so here it is:
How can I set an ad expiration period by category or relate an ad pack to a category (that would have the same result)?
Usage example:
We have a real estate site. One of the categories will be for open houses and the listings there should be free but expire in 14 days. All other listings will have a 30 day expiration period and a cost associated with them.
plugin, code snippet, something I've just missed??
