function media_gallery_item_view in Media Gallery 7.2

Same name and namespace in other branches

1. 7 media_gallery.fields.inc \media_gallery_item_view()

Constructs a drupal_render() array for a media entity displayed within a gallery.

During normal gallery node display, the Field Attach API ensures that all of its fields get rendered. Sometimes, however, we need to display just a single media entity (one item from the multi-valued "media_gallery_file" field) without displaying any other media entities within that field, and without displaying any other gallery node fields, but via a field formatter.
