title: How to automatically refresh the page after submitting a form
body: <p>I have an HTML form, where, when I click "update" the changes do not reflect and it requires a refresh to see the changes.
  But when I reload, there's always <code>Confirm Form Resubmission</code>.</p>
  
  <p>I used <code>&lt;form action="&lt;?php echo htmlspecialchars($_SERVER["PHP_SELF"]);?&gt;" method="post"&gt;</code> which means it submits on the same page.</p>
