I have two content types: Type A and Type B. I have a Node Reference field on content Type A (using References module) that is set to be displayed using the "Rendered Node" version of that referenced node. It references nodes of content Type B. How can I print the content of that field as a rendered node in a custom template file for content Type A?

what do you mean by "print the content of that field"? do you mean body field? – Aboodred1 Jun 10 '13 at 19:21

Can you confirm that you are using drupal.org/project/References ? I just want to edit the question, as how the field is stored varies between the various reference modules for Drupal 7. – mpdonadio♦ Jun 10 '13 at 22:55

@MPD - Good catch. I have edited my answer. – Triskelion Jun 10 '13 at 23:50

@MPD, yes, I am using References. – hockey2112 Jun 11 '13 at 14:00
In your $node object, you will find the subordinate node object at $node->field_fieldname['und'][0]['node']. To render this in a page you have to turn it into a renderable array. You do this with node_view(),specifying the type of display mode. Try:
<?php
if(isset($node->field_fieldname['und'][0]['node'])) {
$second_node = $node->field_fieldname['und'][0]['node'];
$view_mode = 'teaser'; // or 'full' as the case may be
$render_array = node_view( $second_node, $view_mode);
print render($render_array);
}
?>
EDIT
MPD is correct. The above assumes that the field is a Node Reference field. If you are using an Entity Reference field, the code should be changed to:
<?php
if(isset($node->field_fieldname['und'][0]['entity'])) {
$second_node = $node->field_fieldname['und'][0]['entity'];

@MPD - Node reference uses ['nid'] for the id and ['node'] for the object. Entity reference uses ['target_id'] for the id and ['entity'] for the object. The node (or entity) object is included in the field data. Why access the id and separately load the object when it is already there? – Triskelion Jun 11 '13 at 15:56

@Triskelion Odd. I have never seen anything other than ['target_id'] when I dpm() or print_r() a node. – mpdonadio♦ Jun 11 '13 at 18:54

@MPD - I have found that the global
$nodemay be incomplete. When I do aprint_r(), I usually precede it with$full_node=node_load($node->nid). You would be amazed at the differences I find :-) – Triskelion Jun 11 '13 at 19:16
