Create a pipeline processor to convert form data in a custom personalization token

Current version: 10.0

You can set up EXM to initiate an automated email campaign once the customer has completed and submitted a form from a site. However, you might want to transform the original form field value to a different format for use as a custom personalization token in the rendered email message.

In the following example, the pipeline processor transforms the value of a check box list field and renders it as a list of comma-separated values. You can use the same logic for any type of form control.

To implement a new pipeline processor:

Implement a TransformCheckboxList processor that checks for the CheckBoxListViewModel field and transforms the original value of the field from a List<string> to a comma-separated string and sets the TransformedTokenValue property value:

RequestResponsec#

public class TransformCheckboxList : Sitecore.EmailCampaign.Cd.Pipelines.TransformFormsCustomToken.ITransformFormsCustomTokenProcessor
    {
        public void Process(Sitecore.EmailCampaign.Cd.Pipelines.TransformFormsCustomToken.TransformFormsCustomTokenArgs args)
        {
            if (args == null)
            {
                throw new ArgumentException();
            }

            if (args.Field is Sitecore.ExperienceForms.Mvc.Models.Fields.CheckBoxListViewModel checkBoxListViewModel)
            {
                List<string> checkboxListValues = checkBoxListViewModel.Value;

                args.TransformedTokenValue = string.Join(", ", checkboxListValues);
            }
        }
    }

Patch the Sitecore configuration to include the processor implemented in the transformFormsCustomToken pipeline:

RequestResponsexml

 	<configuration xmlns:patch="http://www.sitecore.net/xmlconfig/" xmlns:role="http://www.sitecore.net/xmlconfig/role/">
    <sitecore role:require="Standalone or ContentDelivery">
        <pipelines>

            <group groupName="exm.sendEmailSubmitAction">
                <pipelines>
                    <transformFormsCustomToken>
                        <!-- Transforms the checkbox list field value from a List<string> to a comma separated string -->
                        <processor type="Sitecore.EmailCampaign.Samples.FormsIntegration.Pipelines.TransformFormsCustomToken.TransformCheckboxList, Sitecore.EmailCampaign.Samples.FormsIntegration" />
                    </transformFormsCustomToken>
                </pipelines>
            </group>

        </pipelines>
    </sitecore>
</configuration>
