field_read_instance

7 field.crud.inc field_read_instance($entity_type, $field_name, $bundle, $include_additional = array())

Reads a single instance record from the database.

Generally, you should use field_info_instance() instead, as it provides caching and allows other modules the opportunity to append additional formatters, widgets, and other information.

Parameters

$entity_type: The type of entity to which the field is bound.

$field_name: The field name to read.

$bundle: The bundle to which the field is bound.

array $include_additional: The default behavior of this function is to not return an instance that has been deleted, or whose field is inactive. Setting $include_additional['include_inactive'] or $include_additional['include_deleted'] to TRUE will override this behavior.

Return value

An instance structure, or FALSE.
