        echo "<table border='1' cellpadding='10'>";
        echo "<tr> <th>Imie</th> <th>Nazwisko</th> <th>Nazwa Użytkownika</th> <th>Email</th><th>Ostatnia Wizyta</th><th></th> <th></th></tr>";

        while($row = mysql_fetch_array( $result )) {

                echo "<tr>";

<?php

        include('config.php');

        if (isset($_GET['userid']) && is_numeric($_GET['userid']))
        {
                $query = ("DELETE FROM users WHERE fieldname = '".$_GET["userid"]."' LIMIT 1");

$result = mysql_query($query);
                header("Location: display.php");
        }
        else
        {
                header("Location: error.php");
        }

?>

-- Struktura tabeli dla  `users`
--

CREATE TABLE IF NOT EXISTS `users` (
  `userid` int(25) NOT NULL AUTO_INCREMENT,
  `firstname` varchar(25) COLLATE utf8_unicode_ci NOT NULL DEFAULT '',
  `lastname` varchar(25) COLLATE utf8_unicode_ci NOT NULL DEFAULT '',
  `email` varchar(50) COLLATE utf8_unicode_ci NOT NULL DEFAULT '',
  `username` varchar(25) COLLATE utf8_unicode_ci NOT NULL DEFAULT '',

  `role` varchar(15) COLLATE utf8_unicode_ci NOT NULL DEFAULT 'customer',
  `last_visit` datetime NOT NULL DEFAULT '0000-00-00 00:00:00',
  PRIMARY KEY (`userid`),
