How to render entity referenced nodes field inside node.tpl.php?

Question

I have 2 content types: book and author.

This is the structure:

I want to use (print) some fields of author content type inside the node-book-tpl.php.

How can I do that? Is there a method to print referenced entity's fields like <?php print render($content['field_author']); ?> etc.?

Note: I tried the Inline Entity Display module but because I want to do this with custom node-book.tpl.php it doesn't work for me.

Answer 1

If there is no compelling reason to render the fields from within the template, you could simply:

1. choose a certain view mode for your author content type, say: Token, and make it show only those fields you want to be visible in the book node;
2. set the display of the field referencing the author node from the book node to "Rendered entity" / "Rendered as Token".

Answer 2

As you say author is also a content type. Then you get author content node id on book content.if get node id then use node_load($author_nid); to load author node.print_r() load node and print fields you want to show.
