title: File upload over multiple pages
body: <p>I'm creating a php form that works in this way:</p>
  
  <p>1) The user fills the form and add a file to upload;</p>
  
  <p>2) The submitted information is shown to the user for confirmation;</p>
  
  <p>3) Upon confirmation, a email is sent with all the data, including the file.</p>
  
  <p>My problem is that I get access to the uploaded file on the second step, but not on the third step. Due to security reasons, it's not possible to resend the file on the second step by creating a input file field with a default value (the uploaded file).</p>
  
  <p>It's possible to achieve what I'm trying to do, without having to copy the uploaded file to another folder?</p>
