ok, you have this form on form.html
<form action="verify.php" method="post">
<input type="text" name="testing">
<input type="submit" name="send">
</form>
now on your verify.php page you need something like
<?
if (isset($_POST['send']))
{
echo $_POST['testing']; instead of just $testing
}
else
{
//show form again or whatever, if someone goes here without clicking submit
}
?>
and again, did you/your host upgrade PHP recently
