function field_attach_insert

Save field data for a new entity.

The passed-in entity must already contain its id and (if applicable) revision id attributes. Default values (if any) will be saved for fields not present in the $entity.

Parameters

$entity_type: The type of $entity; e.g. 'node' or 'user'.

$entity: The entity with fields to save.

Return value

Default values (if any) will be added to the $entity parameter for fields it leaves unspecified.
