function hook_field_update_instance

Act on a field instance being updated.

This hook lets modules react to the update of an existing field instance. It is called after the definition is saved, so it cannot be used to modify the instance itself.

Parameters

$instance: The instance as it is post-update.

$prior_$instance: The instance as it was pre-update.
