Yes:

mydomain.com/?category=cat1,cat2,cat3

That appears to not work. Either as you have mentioned above or by going into the Razor and using:

var posts = PostService.Instance.GetPosts(Model.Id, tag, "cat1,cat2", author, searchTerm, commenter, page-1, count);

No posts are returned.

Oops!

My mistake.

I thought I already implemented that. I had to do that for a client. I thought I already integrated it into ublogsy.

#h5is

A work around would be to split the category query string.

Then in a for loop, call GetPosts iwth the current category.

Ah right. Can you tell me how I can concatenate all the different results together and then order by post date before displaying them?

I would assume if I had two sets of nodes for example

var posts1 = PostService.Instance.GetPosts(Model.Id, tag, "cat1", author, searchTerm, commenter, page-1, count);

var posts2 = PostService.Instance.GetPosts(Model.Id, tag, "cat2", author, searchTerm, commenter, page-1, count);

That Library.Concatenate isn't going to work as I think that's just a string concat right? Sorry I'm quite new to Razor.

Thank you for your help. One last question, can I reorder the List according to postdate?

var ordered = posts.OrderByDescending(x => x.GetPropertyValue("uBlogsyPostDate"));

Is it possible to pass to category the list of categories?

I solved in this way:

var tuttiposts = new List<DynamicNode>();

var nodescategories = PostService.Instance.GetPosts(Model.Id);

        foreach (var n in nodescategories)

        {

            allCategories.AddRange(n.uBlogsyPostCategories.Split(",".ToCharArray(), StringSplitOptions.RemoveEmptyEntries));

        }

        // get only distinct categories

        IEnumerable<string> elencocategorie = allCategories.Distinct();

        if (elencocategorie.Count() > 0){

                    foreach (var c in elencocategorie)

                    {

                        if ((!string.IsNullOrEmpty(c.Trim())) && (c!="News"))

                        {

                          var posts1 = PostService.Instance.GetPosts(Model.Id, tag, c, author, searchTerm, commenter, page-1, count);

     tuttiposts.AddRange(posts1);  

                        }

                    }

          }

 var orderedposts = tuttiposts.OrderByDescending(x => x.GetPropertyValue("uBlogsyPostDate")).Distinct().Take(count);

   @foreach (DynamicNode n in orderedposts)  

        {

         ...........

         }

is working on a reply...
