After using your search box with the keyword "filters date" i can't find a post related to my question.
Let's say in my pt_product i have a field with the release date of my products like : date = 19/08/2013
what i have to do for have in the search.php a filter for order my price with the release date.
Old filters :
Order by: Relevance | Price: Low to High, High to Low
New filter i wish :
Order by: Relevance | Price: Low to High, High to Low | release date : Low to High, High to Low
Thx you for your help.
