Setting a Page's Title from a Controller

Concrete 5.7.4 introduces a cool new service object: SEO Helper.

$seo = \Core::make('helper/seo');

This will return an instance of the \Concrete\Core\Html\Service\Seo object, which has a number of interesting methods available to it.

• setSiteName
• addTitleSegment
• setTitleFormat
• setTitleSegmentSeparator

Use this service object to set your site's title from anywhere, or modify the existing title of the page. For example, let's say you want to render a custom view for a single page at a controller method:

public function view_album($albumID = null)
{
    $selectedAlbum = \Foo\Media\Album::getByID($albumID);
    $this->set('albumID', $albumID);
    $this->set('album', $selectedAlbum);
    $this->render('/media/albums');
}

While this method will work to render the albums list – the name of the page will be unchanged. Why not change the page's name as well?

public function view_album($albumID = null)
{
    $selectedAlbum = \Foo\Media\Album::getByID($albumID);
    $this->set('albumID', $albumID);
    $this->set('album', $selectedAlbum);
    $this->render('/media/albums');
    $seo = \Core::make("helper/seo");
    $seo->addTitleSegment('Albums');
}

This can even work from a block view. Check out how the Page List block listens for the active topic filtering a page, and then modifies the page's title accordingly:

public function action_filter_by_topic($treeNodeID = false, $topic = false)
{
    if ($treeNodeID) {
        $this->list->filterByTopic(intval($treeNodeID));
        $topicObj = Topic::getByID(intval($treeNodeID));
        if (is_object($topicObj)) {
            $seo = Core::make('helper/seo');
            $seo->addTitleSegment($topicObj->getTreeNodeDisplayName());
        }
    }
    $this->view();
}
