Anyone? :-)

Hi Mikkel,

It's not clear where you have the problem.

Is it backend or front-end?

It seems that you store the System values instead of the Name of the option.

One good Ideea would be to use "_" or "-" instead of trimming the space for the system values. This way it is more readable and you can process them back if you need the space.

I am having the problem when outputting the Values from the multi-dropdown to the frontend..

In the backend I set up the dropdown as follow

Name - Value ----> Car Parts - carparts (im not allowed to make spaces in the value field) gives me an error.

Which means when I output the list on the frontend i get carparts. I can however insert e.g. Car_Parts as a value. Though i do have several options where special characters such as ( - / ) etc. are being used, though these are not allowed to set as values as well which gives me another problem :)

Yeah, this is a bit of an isue. For some reason Dynamicweb doesn't expose the labels, just the underlying values. I typically use one of the following two solutions:

- Use underscores in the value and then dislplay them using TagName.Replace('_', '')

- Write extensibility code targeting the API that retrieves the labels and makes them available in your page.

Hey Imar,

Thanks for you reply.

I think the first solution, wit the TagName.Replace('_', ") would be my way to do it as it is. Do you though have an example of the last solution. I will sure look into this, if it's easy and kinda time-effective to come by, since that solution is "nicer" to me than the first :-)

Hi Mikkel,

Something like this would do the trick:

using System.Collections.Generic;
using System.Linq;
using Dynamicweb.eCommerce.Products.Categories;
using Dynamicweb.Extensibility;
using Dynamicweb.Rendering;

namespace Your.Project
{
  [AddInName("RenderProductFieldLabels")]
  public class RenderProductFieldLabels : TagExtensionMethod
  {
    public override string ExecuteMethod(string value)
    {
      // Get the ProductCategory
      string productCategoryName = Arguments[0].ToString();
      var productCategory = Category.GetCategoryByID(productCategoryName);
      if (productCategory == null) return value;

      // Get the FieldName
      string productCategoryFieldName = Arguments[1].ToString();
      var productFieldName = productCategory.Fields.FirstOrDefault(x => x.ID == productCategoryFieldName);
      if (productFieldName == null) return value;

      // Get the FieldOptions
      var availableOptions = productFieldName.FieldOptions;

      // Determine the separator that is placed between the items
      string separator = Arguments[2].ToString();

      // Get the selected options for this product
      var selectedOptions = new List<string>(value.Split(','));

      // Find the options in the available options that are selected and then grab their Name (which is the Label in the backend)
      var optionsList = availableOptions.Where(x => selectedOptions.Contains(x.Value)).Select(x => x.Name);

      return string.Join(separator, optionsList.ToArray());
    }
  }
}

This code expected three parameters: the system name of the product category, the system name of the individual field, and the separator that will be placed between items if you have a multi-select like a check box list. You can call it as follows:

<!--@Ecom:Product.CategoryField.CategorySystemName.FieldSystemName.Value.RenderProductFieldLabels("CategorySystemName", "FieldSystemName", "<br />")-->

This puts each item on a separate line. If you pass a comma you get a comma separated list. You can modify the code to render wrapping tags too, like an <li>

Hope this helps,

Imar
