<?php
$action = "loginact.php"; /* The filename that the results will go to. To test script one use loginact.php, for script two use loginmysql.php */
// MySQL Data
$dbuser = "web52230";
$dbpass = "Ikke offentligt :)";
$dbhost = "db.ringler.dk";
$db = "web52230";
// For script one
$admin_user = "admin";
$admin_pass = "admin";
function connect(){
$cnx = mysql_connect($dbhost, $dbuser, $dbpass );
mysql_select_db($db);
}
