Retrieves information about field instances.

Use of this function to retrieve instances across separate bundles (i.e. when the $bundle parameter is NULL) should be avoided when possible, since it loads and statically caches a potentially large array of information. Use field_info_field_map() instead.

When retrieving the instances of a specific bundle (i.e. when both $entity_type and $bundle_name are provided), the function also populates a static cache with the corresponding field definitions, allowing fast retrieval of field_info_field() later in the request.

Parameters

$entity_type: (optional) The entity type for which to return instances.

$bundle_name: (optional) The bundle name for which to return instances. If $entity_type is NULL, the $bundle_name parameter is ignored.

Return value

If $entity_type is not set, return all instances keyed by entity type and bundle name. If $entity_type is set, return all instances for that entity type, keyed by bundle name. If $entity_type and $bundle_name are set, return all instances for that bundle.
