The Ninja Forms extension for Download Monitor allows you to require users to fill in a Ninja Forms form before they gain access to a download.
Simply open the downloads you would like to be locked with a Ninja Forms form and select a form. Downloads with a form attached will be only be accessible after the form is successfully completed.
The Ninja Forms extension adds an easy to use shortcode that will display the form wherever you want. The shortcode only generates the form, giving you absolute freedom to build your own awesome download pages.
All entered data is stored to your Ninja Forms form like with your other forms. Entries are easy exportable to a csv file.

The Ninja Forms extension requires the Ninja Forms plugin installed and activated to work.
