title: How could I display a PDF file in the browser from an input field
body: <p>I want to have an input field in a form using method "post". In the form there will be an attachment field where a user can upload PDF files. </p>
  
  <p>On another page I want the user to be able to view the uploaded pdf file IN the browser using a viewer. </p>
  
  <p>What would be the best way to do this without having the user download/open the PDF file in a separate program?</p>
  
  <p>Thanks!</p>
