View helpers

octopusViewer

You can use this view helper to display the viewer for all media of an item like this:

<?= $this->octopusViewer()->forItem($itemRepresentation) ?>

Or you can display any media matching some criteria:

<?= $this->octopusViewer()->viewer($media_query, $viewer_title) ?>

For instance,

<?= $this->octopusViewer()->viewer(
    [
        'media_type' => 'image/jpeg',
        'item_id' => $item->id(),
    ],
    'Pictures'
) ?>

The list of available parameters can be found in Omeka S developer documentation (API reference).
