Automatisk Linjeskift?

Er det muligt at lave det sådan, at når man trykker Enter i besked-feltet, så vil den automatisk lave lijeskift. (<br>)

<? include "config.php"; ?>

<?
if (isset($_POST['action']) && $_POST['action']=='update'){
    $emne = ($_POST['emne']);
    $fra = ($_POST['fra']);
    $besked = ($_POST['besked']);

    mysql_query("INSERT INTO tagwall SET fra = '$fra',emne = '$emne',besked = '$besked'");

}
?>
