title: Ninja Forms - using form data after submission
body: <p>I have a wordpress website, in which there's a form page, based on <a href="https://ninjaforms.com/" rel="nofollow">ninja forms</a> form plugin.</p>
  
  <p>After a user <strong>submit</strong> the form, I'd like to process the input (preferably on server side) and display it right away (either by redirecting to another page, or on the same page).</p>
  
  <p>How can I do that?</p>
