Adapt a filtering script to be used with database and multiple jquery sliders

I already have a working script that filters items based on different filtering criterias. This script have a version working with a sqlite db file. Starting from this version of the script, i need to: 1/ connect it to a database instead of sqlite file (adapt the small php part linked to db connexion/create a database from the sqlite file) 2/ add jquery sliders and adapt the filter ajax callback on the database based on multiple jquery sliders (it should make a selection on database items based on the value of the slider we just moved but also on the values of the other sliders that did not move and refresh the view of the items).
