I want to get (and to set after) the value of a field collection in a field collection (multidimensional field content).

This is my code :

// The node is a custom content.

// I get the list of first collections fields.
$temp = field_collection_get($node,'field_top');
// Shows the structure you can see below in the screenshot.

// Now, I want to get the value of field_website_informations.
// I've tried several ways but I couldn't find the right way.
// The following line returns an error.
$testage = entity_metadata_wrapper($temp->value()[0], 'field_website_informations');

Is it possible to do with the Entity API?

Yes it is possible. Let's say you have a content type with a field collection named field_collection_parent, which has a field collection in it named field_collection_child, which has a field in it named field_child.

// First you need to wrap the node with entity_metadata_wrapper
$node_wrapper = entity_metadata_wrapper('node', $node);

// To get the value of field_child:
$value = $node_wrapper

// UPDATE: If a field accepts multiple values, treat it like an array
// The following line would get the first value of field_collection_child in the 
// first field_collection_parent.
$value = $node_wrapper

// To set/modify the value of field_child
  ->set('Some new value');

// To save the node after modifying
  • Thanks for help =) When I try : $value = $temp->field_top->field_website_informations->value(); I obtain this error : Undefined property: EntityListWrapper::$field_website_informations I don't understand... My custom content contain a field collection named "field_top". In the admin panel for field collection, I can see the "field top" who contain the sub-collection field "field_website_informations" Jul 13, 2014 at 12:05
  • Ok, as it seems, the field field_top is a multi-value field. I updated my answer accordingly.
