Translate value of WFFM checkbox field in email

Question

I'm currently setting up some Save Actions and 1 of them is 'Send Email Action'. In the sent mail, the value of a checkbox field is always 'True' or 'False'.

Since it is a multilingual site, this needs to be translated properly. Where can I configure this?

Answer 1

You can override Checkbox class and add Adapter attribute. It's there in WFFM already. I have no idea why it's not used by default.

namespace WffmCustomization
{
    [Adapter(typeof(CheckboxAdapter))]
    public class Checkbox : Sitecore.Form.Web.UI.Controls.Checkbox
    {
    }
}

Set Assembly and Class fields of /sitecore/system/Modules/Web Forms for Marketers/Settings/Field Types/Simple Types/Checkbox item to your Checkbox class:

Then add entries with Key set to Selected and Not Selected (camel case - important) in the language you need.

Answer 2

To get the translated value in the mail body, we added a processor in the processMessage pipeline.

<processMessage patch:source="Sitecore.Forms.config">
  <processor type="WFFM.Customization.SaveActions.EmailExt, WFFM.Customization" method="TranslateValues"/> 
</processMessage>

public class EmailExt
{
    public EmailExt()
    { }

    public void TranslateValues(ProcessMessageArgs args)
    {
        // logic to translate
        foreach (AdaptedControlResult result in args.Fields)
        {

        }
    }
}
