I'm trying to figure out if it's possible to filter by an age. If my content has two fields: min_age and max_age, is it possible to return results where the submitted number is between those two values?
For instance, if I have a post where the age range is 18-25, and someone filters with an age of 20, this post would be included, but if they submit 30, it would be excluded.
Well - so basically you have two custom fields that stores min and max age respectively. So, yes I think its easy, you need to add query filters for both of your filters.
