Category - filter by manufacturer

Hi,

Is there a way to filter products in a category by manufacturer.

To better explain, i have sub categories set up, e.g. Bath Panel within the Bath category. There are still a lot of bath panels, what would be useful is a way of filtering bath panels by maufacturer.

Or vice versa, when you click on a particular manufacturer, there a loads of products, what would be nice, is then filtering the specific manufacturer by the categories already set up.

Is there a way to do this, or perhaps suggestions on how to alter the code?

Thanks in advance.

It's not supported out of the box

Found this from another post and thought I'd respond.

You can filter by attributes.

Therefore you can create a manufacturer attribute and filter by that. Does mean adding that attribute to each product.

In a similar way you can add a category attribute and filter by that. (Not sure if Manufacturers has filtering but shouldn't be to hard to look how it's done elsewhere and copy/modify.

+1 ^ exactly what I was going to say.

We Done It in Nopcommerce 2.40

Step:1

Nop.Web=>Models=>Models=> Catalog=>CategoryModel.cs

public class CategoryModel : BaseNopEntityModel
    {
    public CategoryModel()
        {
           ......................code...........................
           ......................code..........................
            /* Added For manufacturer Filter */
            this.AvailableManufacturers = new List<SelectListItem>();
        }
        ..........................code.......................
        ..........................code........................
        /* Added For manufacturer Filter */
         public IList<SelectListItem> AvailableManufacturers { get; set; }
    }

Step:2

Nop.Web=>Controller=> CatalogController.cs

In #region  Categories

namespace Nop.Web.Controllers
{
    public class CatalogController : BaseNopController
    {
        #region Fields 
          ----- code----

         #region Categories 

         public ActionResult Category(int categoryId, CatalogPagingFilteringModel command)
           {
            
       ---------------code------------------

            var model = category.ToModel();


     /*Added For manufacturer Filter */
                                 
    int manid;

    if (Request.QueryString["manufacturerId"] != null)
      {
          manid = Convert.ToInt16(Request.QueryString["manufacturerId"]);
     }
      else
        {
                manid = Convert.ToInt16(Request.QueryString["manufacturerId"]);
         }

   var manufacturers = _manufacturerService.GetAllManufacturers();

    if (manufacturers.Count > 0)
     {
        var PageUrl = _webHelper.GetThisPageUrl(true);
        var Url = _webHelper.ModifyQueryString(PageUrl, "manufacturerId=" + (0).ToString(), null);
       model.AvailableManufacturers.Add(new SelectListItem() 
     { 
        Text =  _localizationService.GetResource("Admin.Common.All"), Value = Url 
      });

   foreach (var m in manufacturers)
  {
     var currentPageUrl = _webHelper.GetThisPageUrl(true);
   var sortUrl = _webHelper.ModifyQueryString(currentPageUrl, "manufacturerId=" + (m.Id).ToString(), null);
     model.AvailableManufacturers.Add(new SelectListItem()
   {

                  Value = sortUrl,
                  Selected = m.Id== manid,

               });
          }
      }

Snowp - Thank you very much, saved me a lot of time!

snowp----Thank you Very Much !!!!!

someone was able to adjust Snowp solution to version 3.1?

with this solution i can get a dropdownlist with all the manufacturers , not only the relevance for the current chosen category and it's also not realy filtering after choosing one of the manufacturers..
