Sitemap

This extension will automatically create XML sitemaps for your Bolt sites. After enabling the extension, go to http://example.org/sitemap.xml to see it.

The bigger search-engines like Google and Bing will automatically pick up your sitemap after a while, but it's always a good idea to explicitly tell the search engines where to find it. To do so, this extension automatically adds the link to the <head> section of your pages:

<link rel="sitemap" type="application/xml" title="Sitemap" href="/sitemap.xml" />

Apart from that, it's good practice to also add the following line to your robots.txt file:

Sitemap: http://example.org/sitemap.xml

Obviously, you should replace 'example.org' with the domain name of your website.

This extension adds a 'route' for /sitemap.xml and /sitemap by default, but it has lower priority than user defined routes.

If you use the pagebinding in routing.yml, or anything similar route that would match 'sitemap' first, you will need to add the following above that route. You should also do this if you have an extension that might override the default routing, like the AnimalDesign/bolt-translate extension.

sitemap:
  path: /sitemap
  defaults: { _controller: sitemap.controller:sitemap }

sitemapXml:
  path: /sitemap.xml
  defaults: { _controller: sitemap.controller:sitemapXml }

Note, if you have a ContentType with the property searchable: false, that content type will be ignored.

Advanced links list control

If you have your own bundled extension you can add, remove or change links before the sitemap is rendered. You need to subscribe to the SitemapEvents::AFTER_COLLECTING_LINKS event. The object you will get is an instance of SitemapEvent class which has a getLinks method that returns a MutableBag object. The last one is an array-like list of links. See example:

protected function subscribe($dispatcher)
{
    $dispatcher->addListener(SitemapEvents::AFTER_COLLECTING_LINKS,
        function ($event) {
            /** @var SitemapEvent $event */
            $links = $event->getLinks();
            $links->add([
                'link'  => '/lorem-ipsum',
                'title' => 'Hello World!',
                'depth' => 1,
            ]);
        }
    );
}

Sitemap stylesheets

You can customize the sitemap with an xslt stylesheet if you copy the templates/sitemap_xml.twig file and the web/sitemap.xsl file to your theme directory and by adding the xsl-stylesheet declaration after the xml declaration so the first two lines of the themes/{yourthemename}/sitemap_xml.twig look like:

<?xml version="1.0" encoding="UTF-8"?>
<?xml-stylesheet type="text/xsl" href="{{ paths.theme }}/sitemap.xsl"?>
