Using Hidden Fields in Pardot Forms

What are hidden fields?

Hidden fields are form fields which are not visible to visitors. Since visitors cannot see or enter information in hidden fields, these fields are used to gather additional information and associate it with that form submission.

You can use hidden fields to collect:

  • The name of the Content Track on which a visitor submits the form
  • The name or URL of the content asset on which a visitor submits a form

Gathering this information is useful for understanding where the form event occurred in the Content Track!

How to use hidden fields

Here are the step-by-step instructions on how to pass information to a hidden field on a form in Pardot.

  1. Create a custom hidden field in Pardot.
    • Navigate to Admin.
    • Select Configure Fields, and then Prospect Fields.
    • Select Add Custom Field.

  3. On the Completion Actions page, select the Thank You Code tab and add the PathFactory Confirmation Page Capture Tag.
    • Add the following code snippet:
      <script< span=""> id="lookbook-capture-tag" src="https://app.cdn.lookbookhq.com/libraries/capture/capture.js" data-email="%%email%%"></script<>

  4. Once you Confirm and Save your form, copy the URL given for the form. Use this URL to make an External URL form in PathFactory.

  5. In PathFactory, manually add a query string to the end of the form’s URL. This will cause the hidden field to pick up the desired value.
    In this example we are going to capture the name of the Content Track that the form was filled out on. This would be done as follows:

    If you are using other query string values (for example, UTM Parameters) do not add a second question mark. Simply separate each query string value with an ampersand (&).
    It doesn’t matter whether the UTM Parameters are listed before or after this hidden field query.
    Example: https://pardot.exampleformurl.com?track_name={{experience.name}}&utm_source=twitter&utm_campaign=spring2018
