Our website is [url removed, login to view]
Basically we feel we have too many categories and would like to reduce the number of categories we have (which we will do) and instead have a box at the top of each category page which allows the customer to refine their results using pre-set options which are relevant to that category.
For example, if you visit [url removed, login to view] you will see a working example where the customer can refine their choice of mattress by selecting a size, type, brand, price, etc.
Also, if you visit [url removed, login to view] you will see another working example except the refine options are slightly different, e.g. you can refine by bed material, finish, etc.
I would like the feature to work just like the example on Bedroom World where you can remove filters individually as well if you click then in error or change your mind and want to remove a particular filter.
I have already modified osCommerce so that when adding a product to the database the mattress type, brand, size, price, material, finish etc is already input so you don't have to do this work.
I'd also like the ability to then sort the results by price, A-Z and availability (all of this is already stored in the database!).
If you can provide me with a working example for refining the mattresses then I'm confident to modify this code and then apply it to the other categories to save you the time or you can do it for all categories and we'll sort out an extra payment. To make it clear, you are bidding to provide me with only a filter for the mattresses.
Ideally I'd like this to be done via AJAX but if this is not possible then I'm still interested but please make this clear when bidding whether you'll be using AJAX or not.
I'm pretty good with osCommerce, PHP, etc so can answer any detailed questions you may have but unfortunately this task is beyond me so your help is much appreciated.
Many thanks, Michael.
