");
$form = $_POST;
$fn = $form['fn'];
$ln = $form['ln'];
$psw = $form['psw'];
$values = array(
':fn' => $fn ,
':ln' => $ln ,
':psw' => $psw
);
$stmt = $db->prepare($sql);
$stmt->execute($values);
if ( $stmt ){
echo "<p>Thank you. You have been registered</p>";
} else {
echo "<p>Sorry, there has been a problem inserting your details. Please contact admin.</p>";
}
