    Looks like you need a WHERE clause in your UPDATE query to tell it which row to update, presumably on the ID field, which it appears will be available in $_GET['ID'].

    PHP Code:
    if(empty($_GET['id']) or !ctype_digit($_GET['ID'])) {
      die(
    "ID not received or it is not an integer.");
    }
    $id = (int) $_GET['ID'];
    $sql "
      UPDATE logins SET 
        Website_applicatie ='
    $web_app_save',
        Login ='
    $login_save',
        Pass ='
    $pass_save',
        Notitie ='
    $notitie_save',
        Hyperlink ='
    $hyperlink_save'
      WHERE ID = 
    $id
    "
    ;
    mysql_query($sql);

    It would replace this line:
    PHP Code:
        mysql_query("UPDATE logins SET Website_applicatie ='$web_app_save', Login ='$login_save', Pass ='$pass_save', Notitie ='$notitie_save', Hyperlink ='$hyperlink_save'"
