Code: [Select]

<?php

$include = "hjem.php";
$vis = $_GET['vis'];
if (isset($vis)) {
$cs = explode("/", $vis);
if (!empty($cs[1])) { 
$include = str_replace("/", "", $vis);
} else { $include = "$vis.php"; }
}
if (!file_exists($include)) { $include = "missing.php"; }
require_once($include);

?>


Notice: Undefined index: vis in /web/sirkulus/beta/index.php on line 56

Code: [Select]

<?php

$include = "hjem.php";
if (isset($_GET['vis'])) {
         $vis = $_GET['vis'];
$cs = explode("/", $vis);
if (!empty($cs[1])) { 
$include = str_replace("/", "", $vis);
} else { $include = "$vis.php"; }
}
if (!file_exists($include)) { $include = "missing.php"; }
require_once($include);

?>

It is the $_GET you have to check for isset as that is the array with the "unknown" index.
