How can I present different types in my sitemap.

Standard it only present the rootlevel type Page. What if, for example, there is a articlePage and a Page type?

function SiteMap() {
$rootLevel = DataObject::get("Page", "ParentID = 0"); // Pages at the root level only
$output = "";
$output = $this->makeList($rootLevel);
return $output;
}

this is easy,

just add the articlePage type to that too

function SiteMap() {
$rootLevel = DataObject::get("Page", "ParentID = 0"); // Pages at the root level only
$output = "";
$output = $this->makeList($rootLevel);
$articlePages = DataObject::get("ArticlePage", "ParentID = 0"); // Pages at the root level only
$output = $this->makeList($articlePages);
return $output;
}

I forgot to mention, on the first Page.php the make list function can be further edited to make the page levels too, with adding sub lists, and so on.

It doesn't seem to work, can you please explain further?

Problem solved. Sitemap works fine.

function SiteMap()
{
$output = "";

$rootLevel = DataObject::get("SiteTree", "ParentID = 0");
$output = $this->makeList($rootLevel);

return $output;
}

Thanks for posting this, that's has solved my problem too.
