I have a content type (a) referenced to another content type (b) by url widget, how can I get the ID of the referenced node (b)?
Thanks.

i need to get the node id for getting it's fields values and using them in node(a) fields — abd, Apr 4 '12 at 15:00
So you probably want to write a module and implement some custom code in this hook for example. — Countzero, Apr 4 '12 at 15:03
what function can fulfill (get the nid for referenced node)? — abd, Apr 4 '12 at 15:08
There's no function. You have to retrieve it with your own code from the $build variable. Please read the doc in the page referenced above. — Countzero, Apr 4 '12 at 15:25

You can get node id using :

$nid = $node->field_reference['und'][0]['nid'];

And you can check it out from this:

drupal_set_message($nid);
