function field_info_instance

Returns an array of instance data for a specific field and bundle.

The function populates a static cache with all fields and instances used in the bundle, allowing fast retrieval of field_info_field() or field_info_instance() later in the request.

Parameters

$entity_type: The entity type for the instance.

$field_name: The field name for the instance.

$bundle_name: The bundle name for the instance.

Return value

An associative array of instance data for the specific field and bundle; NULL if the instance does not exist.
