Category listings

Code examples for category listings.

Facets can be applied to category listings in a similar way to search. Have a look at the facets guide for more details.

Custom filtering and sorting options are also available for category listings. Have a look at the sorting and filtering guide for more details.

Example

The example shows how to list products in a category. The call is structured much like a search call and the parameters work in the same way so have a look at the explanation of search parameters if you’re unsure how they work.

Other than that, listing categories is simply a matter of calling GetEntitiesByAttribute and supplying the name of the category that you want to list.

// Below is an example of a request - response cycle of a category listing request
var request = new GetEntitiesByAttributeRequest("Category", categoryName);
request.ResultsOptions.Skip = 0;
request.ResultsOptions.Take = 9;

var response = _loop54Client.GetEntitiesByAttribute(request);

var results = response.Results.Items;

if (!results.Any())
    Debug.WriteLine("There were no items in this category.");

foreach (var resultItem in results)
{
    var productId = resultItem.GetAttributeValueOrDefault<string>("Id");
    var productTitle = resultItem.GetAttributeValueOrDefault<string>("Title");
    Debug.WriteLine(productId + " " + productTitle);
    //render a product on the category listing page
}

  String productTitle = resultItem.getAttributeValueOrNull("title", String.class);
  System.out.println(productId + " " + productTitle);
