I have a node with a entity reference field (more precisely a product reference). How do I access the fields of the referenced entity from the node?

(I’m trying to do it through a code field in the Display Suite, so I have access to the $entity object, not sure if that helps)

To explain better I would like to be able to do something like these tokens:


but with PHP, so I can cycle through the index.

You can use entity_metadata_wrapper() to easily get referenced entities, their field and much more.

$node_wrapper = entity_metadata_wrapper('node', $entity);

foreach ($node_wrapper->field_products as $product_wrapper) {
  // You can print or do whatever you like with the value of the fields 
  // of the referenced entity like below:
  print $product_wrapper->field_flow_rate->value();

I'm not sure of the exact structure of your node object (use dpm($node) or print_r($node) if you don't have a debugger). But assuming the entity_ref field is called field_products then you would do something like this:

foreach ($node->field_products as $nid) {
  $child = node_load($nid); // might be $nid[0], use dpm to find out
  $flow_rate = $child->flow_rate;
