When you first display the Form, and specify action= you drop into PHP
and actually call the TestPhp() function. The function runs at that
time and updates your value =After Function.
Instead, your POST action should call the original script. You already
have a way to detect that form data is present, so within that test
call the TestPhp() function to updated the value.
<?php
// a debug statement that shows $_POST is empty prior to form action
if (empty ($_POST)) echo "POST data is empty";
else TestPhp();
?>
