title: Download pdf after submission Contact form 7
body: <p>I am currently using the mail to sent the pdf and I want them to <code>auto-download</code> once the contact form is filled.</p>
  
  <p>How can I achieve this?</p>
  
  <p>I have already tried <a href="https://stackoverflow.com/questions/45430803/download-file-after-submission-in-contact-form-7-wordpress">this</a>, and it does not cater my need. </p>
  
  <p>I also tries <code>on_sent_ok: location ="pdf url"</code> but nothing helps.</p>
