Correct,

Have the page POST to itself, validate the form input in PHP and while 
still in PHP, redirect.
Otherwise, if you have errors, generate the applicable HTML.

Here's some pseudo code:

<?php

if (isset($_POST))
{
    //check data
    if (good) location('...');
    else
       echo "<FormWithErrorMessages>";
}
else
{
    echo "<DefaultForm>";
}
