Download Monitor Ninja Forms Lock is a WordPress plugin by WPChill that connects Ninja Forms with Download Monitor.
Many sites give away PDFs, whitepapers, ebooks or other files and learn nothing about who takes them. Download Monitor Ninja Forms Lock addresses this by placing a Ninja Forms form in front of the download. The visitor fills it in first, and then gets the file. That gives you a simple way to gather contact details or build an email list from content you already offer.
The plugin works with Download Monitor, so your files stay managed in the same place. You display the form with a shortcode, which means you can put it on any page and design your own download pages without writing code. Developers can also customize and extend how it behaves. It suits marketers, businesses with gated resources, and agencies looking after client sites.
