Not getting form data on custom Save action form submit

Question

I'm trying to get the form data and store it in text file. I'm not getting the form data in the code.

using System;
using System.IO;
using System.Linq;
using Sitecore.Diagnostics;
using Sitecore.ExperienceForms.Models;
using Sitecore.ExperienceForms.Processing;
using Sitecore.ExperienceForms.Processing.Actions;
using static System.FormattableString;
using Newtonsoft.Json;
using System.Collections.Generic;

    /// Executes a submit action for logging the form submit status.
    /// </summary>
    /// <seealso cref="Sitecore.ExperienceForms.Processing.Actions.SubmitActionBase{TParametersData}" />
    public class LogSubmit : SubmitActionBase<string>
    {
        /// <summary>

        /// </summary>

        public LogSubmit(ISubmitActionData submitActionData) : base(submitActionData)
        {
        }

        protected override bool TryParse(string value, out string target)
        {
            target = string.Empty;
            return true;
        }

        /// <summary>
        /// Executes the action with the specified <paramref name="data" />.
        /// </summary>

            Assert.ArgumentNotNull(formSubmitContext, nameof(formSubmitContext));

            if (!formSubmitContext.HasErrors)
            {
                Logger.Info(Invariant($"Form {formSubmitContext.FormId} submitted successfully."), this);
            }
            else
            {
                Logger.Warn(Invariant($"Form {formSubmitContext.FormId} submitted with errors: {string.Join(", ", formSubmitContext.Errors.Select(t => t.ErrorMessage))}."), this);
            }

            return true;
        }

        public void createFile(string data, FormSubmitContext formSubmitContext)
        {
            string path = @"C:\inetpub\wwwroot\sc-health-grades.sc\SCTest.txt";
            if (!File.Exists(path))
            {
                // Create a file to write to.
                using (StreamWriter sw = File.CreateText(path))
                {
                    sw.WriteLine("Hello");
                    sw.WriteLine("And");
                    sw.WriteLine("Welcome");
                    sw.WriteLine(data);
                    sw.WriteLine(data);
                    sw.WriteLine(formSubmitContext.FormId);
                    sw.WriteLine(formSubmitContext.ButtonId);
                    var emailid = 
                    /// var jsonString = JsonConvert.SerializeObject(formSubmitContext.Fields.SingleOrDefault());
                    /// sw.WriteLine(jsonString);
                    sw.WriteLine("Has errors: " + formSubmitContext.HasErrors);

                }
            }

            // Open the file to read from.
            using (StreamReader sr = File.OpenText(path))
            {
                string s = "";
                while ((s = sr.ReadLine()) != null)
                {
                    Console.WriteLine(s);
                }
            }
        }
    }
}

can someone help me on what I'm doing wrong here ?

Answer 1

The "data" string you are referring to holds the configuration of your submit action. This does not contain the content of the form.

On your submit action sitecore item, the config is stored as json in the parameters field. This json is deserialised into a class you need to create that is passed to your custom submitaction in the "data" parameter. So this "data" you are referring to, is actualy just configuration.

The content of the form can be found in the formSubmitContext.

Have a look at the sitecore documentation on how to build custom submit action. https://doc.sitecore.com/developers/91/sitecore-experience-management/en/walkthrough--creating-a-custom-submit-action.html
