Reads in fields that match an array of conditions.


array $params: An array of conditions to match against. Keys are columns from the 'field_config' table, values are conditions to match. Additionally, conditions on the 'entity_type' and 'bundle' columns from the 'field_config_instance' table are supported (select fields having an instance on a given bundle).

array $include_additional: The default behavior of this function is to not return fields that are inactive or have been deleted. Setting $include_additional['include_inactive'] or $include_additional['include_deleted'] to TRUE will override this behavior.

Return value

An array of fields matching $params. If $include_additional['include_deleted'] is TRUE, the array is keyed by field id, otherwise it is keyed by field name.
