Hidden form fields give you another layer of customization to use with your integration.
Access hidden form fields
Hover over any form widget on your page or pop-up and click Edit Integrations to access its settings, which will appear in the left-hand sidebar.
Creating hidden fields
You can create hidden fields in two ways.
Inside email service providers
Some email service providers (ESP) will allow you to create or define hidden fields. In the example below, “Source” was set up as hidden within MailChimp.
To hide a field manually from within Leadpages:
- Under ② FIELDS in the form settings, click the field you'd like to hide to open its options.
- Then, check the "This is a hidden field" checkbox, enter a default value and click Done.
You can choose any default value the field supports, which will be submitted alongside information your visitor provides.
Pre-populating Hidden Fields
Each hidden field created in Leadpages must have a default value, but you can also dynamically pass in values from a URL parameter (such as one provided by your email service provider or ad software). To set it up, type in your URL variable in the URL Mapping field.
For instance, our page might be at a URL from an ad that includes a variable like so:
http://website.com/registration?ad_campaign=facebook. In this case, we’d put
ad_campaign as our URL variable (without the question mark).
When someone opts into the page on that URL, the hidden field would be populated with “facebook” so we could track which ad campaign our opt-in came from.
