Custom Form Fields keeps giving an error "You need to include 'custom' in the field!" when submitting the form

[DanielRogers-Intelli (Daniel Rogers)]

I have created a new field as per post in the old forum.

public class GenesisSignature : Umbraco.Forms.Core.FieldType
{
public override string GetDesignView() =>
“/App_Plugins/IBDGenesis/UUI-Signature/signature.html”;
public GenesisSignature()
{
this.Id = new Guid(“78f429e3-d27d-4696-8028-5c8830d73909”);
this.Alias = “genesisSignature”;
this.Name = “Signature Pad”;
this.Description = “Displays a canvas to capture a signature or alternativly a text edit box with a generated signature.”;
this.Icon = “wand-magic-sparkles deep-orange”;
this.SortOrder = 100;
this.SupportsRegex = true;
this.SupportsMandatory = true;
this.FieldTypeViewName = “/wwwroot/App_Plugins/IBDGenesis/UUI-Signature/UUI-Signature.cshtml”;
this.DataType = FieldDataType.LongString;
this.RenderInputType = RenderInputType.Single;
}

// Add any custom settings for your field type using the [Setting] attribute
[Setting("Custom Class", Description = "Add a Custom Class to the field", View = "TextField")]
public string CustomClass { get; set; }

[Setting("Image Type", Description = "Use a Prefered Image file type. Default is PNG", View = "TextField")]
public string ImageType { get; set; }

[Setting("Background Color", Description = "Add a background colour in rgba format ie. '150, 150, 0,0.5'", View = "TextField")]
public string BackgroundColour { get; set; }


// You can do custom validation in here which will occur when the form is submitted.
// Any strings returned will cause the submission to be considered invalid.
// Returning an empty collection of strings will indicate that it's valid to proceed.
public override IEnumerable<string> ValidateField(Form form, Field field, IEnumerable<object> postedValues, HttpContext context, IPlaceholderParsingService placeholderParsingService, IFieldTypeStorage fieldTypeStorage)
{
    var returnStrings = new List<string>();

    if (!postedValues.Any(value => value.ToString().ToLower().Contains("custom")))
    {
        returnStrings.Add("You need to include 'custom' in the field!");
    }

    // Also validate it against the default method (to handle mandatory fields and regular expressions)
    return base.ValidateField(form, field, postedValues, context, placeholderParsingService, fieldTypeStorage, returnStrings);
}

}

public class Startup : IComposer
{
public void Compose(IUmbracoBuilder builder)
{
builder.WithCollectionBuilder()
.Add();
}
}

cshtml

@using Umbraco.Forms.Web@model Umbraco.Forms.Web.Models.FieldViewModel

<!-- The below CSS and JS needs moving out of this file only added here for testing -->

@{Html.AddFormThemeCssFile(“/App_Plugins/IBDGenesis/UUI-Signature/UUI-Signature.css”);}

Print your name

Review your signature

Draw your signature

• Type It
• Draw It
• Clear

When I submit the form the text “You need to include ‘custom’ in the field!” keeps coming up as if the validation error.

Hi @DanielRogers-Intelli!

The example is handling the validation and is expecting the word “custom” to be submitted somewhere in the response. If you remove these lines (and replace with your own validation) you’ll be able to submit:

public override IEnumerable<string> ValidateField(Form form, Field field, IEnumerable<object> postedValues, HttpContext context, IPlaceholderParsingService placeholderParsingService, IFieldTypeStorage fieldTypeStorage)
{
-    var returnStrings = new List<string>();
-
-    if (!postedValues.Any(value => value.ToString().ToLower().Contains("custom")))
-    {
-        returnStrings.Add("You need to include 'custom' in the field!");
-    }

    // Also validate it against the default method (to handle mandatory fields and regular expressions)
    return base.ValidateField(form, field, postedValues, context, placeholderParsingService, fieldTypeStorage, returnStrings);
}
