OK, making assumptions about the order of the fields in the form is dangerous.
Making assumptions about the order of an associative array is doubly so,
although PHP seems remarkably forgiving about it.
But assuming that's really what you want:
<?
$pairs = array();
foreach ( array_slice($HTTP_POST_VARS, 2) as $key => $value)
$pairs[] = $key . "='" . $value . "'";
$updateString .= join(', ', $pairs);
?>
