Is anyone aware of a way to query for the date and time a category last had a post added to it?
Please note: I cannot rely on the timestamp of the most recent post in the category, as they do not necessarily reflect the date in which a post was added to a category. For instance, if a post was made on August 1, 2005, and was then added to a category on July 20, 2006, I would want a way to display that the category was last updated on July 20, 2006.
WP doesn’t record a timestamp for when a post is added to a category, so you’d have to modify the DB [the post2cat table] and the core files to do so. Or perhaps the postmeta table, although that would get much messier.
Thanks for getting back to me. I added a timestamp to the post2cat table a long while ago to give myself this functionality, but was hoping that someone with more knowledge of the WordPress DB schema than I would know of a way around doing so.
The ultimate aim was to make my photoblog theme more easily distributable.
