Hi,

Does recaptcha 2 is implemented properly in this case? It seems recaptcha 2 is ignored while submitting details and email is sent.

Have you used a package for Recaptcha 2.0?

I was told by support that my version of forms had a bug with the recaptcha so they sent me these files:

\appcode\ReCaptcha2.cs \AppPlugins\UmbracoForms\Backoffice\Common\FieldTypes\Recaptcha2.html \App_Plugins\UmbracoForms\Images\recaptcha2.png \Views\Partials\Forms\FieldTypes\FieldType.Recaptcha2.cshtml \Views\Partials\Forms\Themes\default\FieldTypes\FieldType.Recaptcha2.cshtml

The cs file referenced a light and dark theme but Neither I nor the person supporting me had that theme. So I was informed to change it to clean and normal which compiled. I also had to add 'using Umbraco.Forms.Core.Attributes;' to get the cs file to compile. Am I missing files?

You can apply break point at ValidateField methods in ReCaptcha2.cs and then navigate to see how it works. This method executes before saving of records and email process. Once this is successful then only rest of the process is completed. Introspecting this method will fix your issue.

You have correct set of files but I am not sure if something is missing from ReCaptcha2.cs

As using Umbraco.Forms.Core.Attributes; is already added in the class.

I don't have the project in visual studios I use the web client to modify the front of the site and Azure to work with the back end files. If I open it in visual studios and attach a debugger its going to bring the whole site down. Do you have a recommendation of how to bring the code down for a test site? I have tried a few things but its not really working.

Please can share recaptcha2.cs

So this is what they gave me:

using Newtonsoft.Json.Linq;
    using System;
    using System.Collections.Generic;
    using System.Net;
    using System.Web;
    using System.Linq;
    using Umbraco.Core.Logging;
    using Umbraco.Forms.Core;
    using Umbraco.Forms.Core.Attributes; 

    namespace WebApplication2.App_Code
{
    public sealed class Recaptcha2 : FieldType
    {
        public Recaptcha2()
        {
            Id = new Guid("B69DEAEB-ED75-4DC9-BFB8-D036BF9D3730");
            Name = "Recaptcha2";
            FieldTypeViewName = "FieldType.Recaptcha2.cshtml";
            Description = "Google Recaptcha v2";
            Icon = "icon-eye";
            DataType = FieldDataType.String;
            SortOrder = 120;
            Category = "Simple";
        }

        [Setting("Theme", prevalues = "clean, normal", description = "ReCaptcha v2 theme", view = "dropdownlist")]
        public string Theme { get; set; }

        [Setting("Size", prevalues = "normal,compact", description = "ReCaptcha v2 size", view = "dropdownlist")]
        public string Size { get; set; }

        [Setting("Error message", description = "The error message to display when the user does not pass the Recaptcha check", view = "TextField")]
        public string ErrorMessage { get; set; }

        public override IEnumerable<string> ValidateField(Form form, Field field, IEnumerable<object> postedValues, HttpContextBase context)
        {
            var secretKey = Configuration.GetSetting("RecaptchaPrivateKey");

            if (string.IsNullOrWhiteSpace(secretKey))
            {
                // just return the error message
                var configurationError = string.Format("ERROR: ReCaptcha v2 is missing the secret key - Please update the '/app_plugins/umbracoforms/umbracoforms.config' to include 'key=\"RecaptchaPrivateKey\"'");
                LogHelper.Warn<Recaptcha2>(configurationError);
                return new[] { configurationError };
            }

            var reCaptchaResponse = HttpContext.Current.Request["g-recaptcha-response"];
            var url = string.Format("https://www.google.com/recaptcha/api/siteverify?secret={0}&response={1}", secretKey, reCaptchaResponse);

            var isSuccess = false;
            var errorCodes = new List<string>();

            using (var client = new WebClient())
            {
                var response = client.DownloadString(url);

                var responseParsed = JObject.Parse(response);

                //Get Success Status
                JToken sucessToken;
                var sucessFound = responseParsed.TryGetValue("success", out sucessToken);
                if (sucessFound)
                {
                    isSuccess = sucessToken.Value<bool>();
                }

                //Get Error codes
                JToken errorsToken;
                var errorsFound = responseParsed.TryGetValue("error-codes", out errorsToken);
                if (errorsFound)
                    errorCodes.AddRange(errorsToken.Children().Select(child => child.Value<string>()));

                if (isSuccess)
                    return Enumerable.Empty<string>();

                var error = field.Settings["ErrorMessage"];
                if (string.IsNullOrWhiteSpace(error))
                    error = "Make sure to complete the \"I am not a robot\" challenge";

                var errors = new List<string> { error };
                errors.AddRange(errorCodes);

                return errors;
            }
        }

        public override bool StoresData
        {
            get
            {
                return false;
            }
        }       
    }
}

It seems to work. I managed to figure out how to download the files and put them into visual studios so I can sort of debug this thing. This works, but it doesn't stop my other code from running and I'm not sure how to capture the results of the captcha. The code that runs next is in a .cshtml file:

@inherits Umbraco.Web.Mvc.UmbracoViewPage
@using Umbraco.Core.Persistence;
@using System.ComponentModel.DataAnnotations;
@using System.Text.RegularExpressions;
@using ContentModels = Umbraco.Web.PublishedContentModels;

@{
    Layout = "MainTemplate.cshtml";
    if (IsPost) {


        string firstname = Request.Form["63b5d8dc-7d73-4f35-b457-ba3753d1cbe3"];
        string lastname = Request.Form["455b5481-0202-4508-be02-5f1c93a1cbd5"];

I attempted to use the Request.Form with the captcha ID but it didnt return a result. Any suggestions on getting this to work?

@AsheM I'm seeing something similar in an implementation and I'm curious if there was ever a resolution for your issue.

Thank you.

Thank you for that information. I've already been eyeing the upgrade path and I think we're going to be heading down that path.

Both are really good suggestions on the upgrade effort. I'm definitely making note of the backups and the possible attempts.

Thank you!

is working on a reply...
