title: How to access Ninja Forms user submitted values in WP
body: <p>My client's WordPress site uses the Ninja Forms plugin for forms. There's a web page with a form that's set up to redirect to another page. I need to access the submitted form data from the redirect page, but the form values don't show up in a $_POST array on the redirect page.</p>
  
  <p>Here's a Ninja Forms support page that I think provides instructions on how to achieve what I'm describing, but it's a bit over my head:</p>

  <p>Do I need to add PHP to the form page?  To the redirect page?  To both?</p>
  
  <p>I'd be grateful if someone who understands this page would have a look and tell me what I need to do to access the submitted form values from the redirect page.</p>
