Recently, I was working on Register form using Sitecore’s Web Forms for Marketers (WFFM) module where I had to make available a checkbox field for Terms of Use and Privacy Policy.  The goal is to have the hyperlink on “Terms of Use” and in “Privacy Policy”, so the user can read before checking the box.

As you can see it did not work out-of-box as I would expect. To achieve the goal and to satisfy the business requirements, I had to implement a custom WFFM checkbox and below I am going to share the steps and implementations details.

Checkbox Custom Field - Implementation

According to the best practices, I am using Helix principles on my Sitecore implementation, so I created the three different layers ( Feature, Foundation, and Project). The implementation of WFFM Custom field will be into Foundation layour through the SitecoreExtensions APS.NET project.

Then, I added the following WFFM dlls to the project through the NuGet Package Manage console. I want to call out your attention to ensure you select the right version according to your Sitecore version.

Sitecore WFFM Abstractions

First all, I started to implement the WFFM Custom field, the CheckboxHTMLField, which inherits CheckboxField from Sitecore.Forms.Mvc.dll.

Once the field was created, I created the view that it will use to render. The cshtml file should be placed in the /Views/Form/EditorTemplates folder.

After creating the view for the component, I created the Model that WFFM will use in the form designer. It is a model which functionality is to allow the form creator to configure the text with a hyperlink for the custom Checkbox label. This class uses items from the Sitecore.Forms.Core.dll. Furthermore, the figure below shows the correspondence between CheckboxHTML class with WFFM Designer.  CheckboxHTML Class and WFFM Form Designer

Checkbox Custom Field – Configuration

After done with implementations and everything is built and compile, I procced with Sitecore configurations where I will have to create the new custom field type in the /sitecore/system/Modules/Web Forms for Marketers/Settings/Field Types/Custom location.  There are three parameters that you need to know.

  • Assembly: DKT.Foundation.SitecoreExtensions.dll (basically it's the project’s dll).
  • Class: DKT.Foundation.SitecoreExtensions.WFFM.CheckboxHTML (basically it’s class model that WFFM will use in the form designer)
  • MVC type: DKT.Foundation.SitecoreExtensions.WFFM.CheckBoxHTMLField, DKT.Foundation.SitecoreExtensions (it’s the exactly new custom field implementation).

WFFM CheckboxHTML configuration

As the last step, you should move manually the views implementations of CheckBoxHTMLField.cshtml from \Website\Views\SitecoreExtensions\ to \Website\Views\Form\EditorTemplates\.

If everything works as I expected you should be able to have the following WFFM designer presentations as I am showing on the screenshot below once you follow up the steps: (1) – Select the forms that you want to add the new CheckboxHTML field. (2) - Click on Form designer. (3) – Then on the field type, you should see available the new CheckboxHTML field.

As the result, you will be able to create a custom checkbox field with a hyperlink.
