I'm trying to use PHP to get user IDs from an Entity Reference of users in a content type.

I have got as far as doing (where I actually get the NID from elsewhere):

$node = node_load(123);

$info = field_get_items('node', $node, 'field_my_users');

But how do I get the IDs from $info?

You just need to get the target_id from each of the field values, which you can do by looping through $info:

$uids = array();
foreach ($info as $field_item) {
  // Entity reference fields store their data in the 'target_id' column
  $uids[] = $field_item['target_id'];
}
  • Hi @Clive, yes %node instead of $node was just a typo in my question - shift+5 vs shift+4 - edited my Q and your A accordingly. I tested this by doing print (string)$field_item['target_id']; and nothing was printed. However, checking count($info) confirms the data is in there. Any ideas? – dav_i Oct 22 '12 at 8:32
  • Could you post a print_r of the output of $info in your question? – Clive Oct 22 '12 at 8:40
  • Agh - I'm an idiot - I had a spelling mistake in my field_get_items(. Your solution works perfectly. Thankyou. – dav_i Oct 22 '12 at 8:56
