Change redirect url after success in WFFM

Question

I have a WFFM form with a hidden field on it. The field contains a value that I would like to know on the success page - in order to use it in custom code in a rendering or even for personalization.

Is there a way to pass data from the form to the success page? Maybe by changing the redirect url and add a querystring...

Using MVC forms in v8.1.

Answer 1

It appears that the pipeline has changed between webforms and MVC. The Success pipeline for MVC is <wffm.success> and can be found in Sitecore.MvcForms.config. Through this you have access to the FormModel

public class SuccessRedirect : FormProcessorBase<IFormModel>
{
    public override void Process(FormProcessorArgs<IFormModel> args)
    {
        Assert.ArgumentNotNull((object)args, "args");
        var model = args.Model as FormModel;
        if (model == null)
            return;
        model.SuccessRedirectUrl = model.SuccessRedirectUrl + "?val=" + model.Results[0].Value;
    }
 }

There is a good post here on it here from Mike Reynolds:

There are a lot of steps though to this approach. You may find it better to save them before redirecting instead as suggested by JammyKam here:

-- UPDATE ---

If you don't want to go for either of these approaches you could try creating a custom save action with a Success Redirect. However I've not tested if you can get the form values from args.Form or not.
