How to render entity referenced nodes field inside node.tpl.php? 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 &lt;?php print render($content['field_author']); ?&gt; 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.
If there is no compelling reason to render the fields from within the template, you could simply:


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;
set the display of the field referencing the author node from the book node to "Rendered entity" / "Rendered as Token".
