Hide custom form field in summary and posted data

Hi!
I have built a custom form field in CMS 11 for a honeypot according to this page https://www.codeart.dk/blog/2020/8/episerver-forms-avoiding-spam-with-a-honeypot/. 
I don't want the form property to be included in either the "summary" or the posted form data. How can achieve that?

SubmissionData.Data.Remove(honeypotElement.ElementName); does not remove the field from either the summary or the posted form data.

Best regards 
Kristian

You can create your own DataSubmissionService

i.e.

    public class CustomDataSubmissionService : DataSubmissionService
    {

Override the SubmitActionResult PerformDataSubmit and remove the fields you do not require

        public override SubmitActionResult PerformDataSubmit(NameValueCollection rawSubmittedData,
            HttpContextBase httpContext, 
            ControllerBase controller)
        {

Then just register in IOC

                context.StructureMap().Configure(c =>
                {
                    c.For<DataSubmissionService>().Use(new CustomDataSubmissionService());
                });

Hi!

But if I remove the honeypot form field in the overridden PerformDataSubmit method I guess I won't be able to check if the honeypot form field has a value or not in my HoneypotActor.

It's in the HoneypotActor I check if the honeypot form field has a value (probably a spam robot has filled it in). If it has a value I cancel the submit.

I only want the honeypot form field to be excluded from "#summary" and stored form submissions.

public class HoneypotActor : PostSubmissionActorBase, ISyncOrderedSubmissionActor
{
public int Order => 1;

public override object Run(object input)
{
var formContainerBlock = FormIdentity.GetFormBlock();
var formElements = formContainerBlock.Form.Steps.SelectMany(st => st.Elements);
var honeypotElements = formElements.Where(elem => elem.SourceContent is HoneypotElementBlock).ToList();
if (honeypotElements.Any())
{
foreach (var honeypotElement in honeypotElements)
{
if (!string.IsNullOrEmpty(SubmissionData.Data[honeypotElement.ElementName]?.ToString()))
{
var formId = formContainerBlock.Content.ContentLink.ID;
var result = new SubmissionActorResult
{
CancelSubmit = true,
ErrorMessage = LocalizationService.Current.GetString("/blocks/honeypotelementblock/errormessage")
};
return result;
}

//Remove data for HoneyPotElement from final data.
SubmissionData.Data.Remove(honeypotElement.ElementName);
}
}

return "";
}
}

Best regards

Kristian
