Once the form has been submitted in the iframe

<form method="POST" action="getForm.php">

The page reloads into getForm.php, and in that file you do:

<?php

    $input = $_POST['input'];
    // process form and do your stuff etc

    echo "<!DOCTYPE html>";
    echo "<head>";
    echo "<title>Form submitted</title>";
    echo "<script type='text/javascript'>window.parent.location.reload()</script>";
    echo "</head>";
    echo "<body></body></html>";

?>

and that would reload the parent page after the form has submitted, now the only question is, why are you submitting through an iFrame if you're going to reload the parent page anyway.
