Redirect in base al testo input

[whisher]

Ciao.
Poi fare una cosa del genere:

<?php 
if(isset($_POST['page']))
{
    $mode = $_POST['page'];
    switch($mode)
    {
        case "home":
        header("Location: home.php");
        exit;
        break;
        case "blog":
        header("Location: blog.php");
        exit;
        break;
        default:
        header("Location: default.php");
        exit;
        break;
    }
}
?>
<form action="<?php echo $_SERVER['PHP_SELF'] ?>" method="post" name="frm">
<input name="page" type="text" />
<input name="submit" type="submit" value="submit">
</form>
