Purges the field data for a single field on a single pseudo-entity.

This is basically the same as field_attach_delete() except it only applies to a single field. The entity itself is not being deleted, and it is quite possible that other field data will remain attached to it.

Parameters

$entity_type: The type of $entity; e.g. 'node' or 'user'.

$entity: The pseudo-entity whose field data is being purged.

$field: The (possibly deleted) field whose data is being purged.

$instance: The deleted field instance whose data is being purged.

function field_purge_data($entity_type, $entity, $field, $instance) {
  // Each field type's hook_field_delete() only expects to operate on a single
  // field at a time, so we can use it as-is for purging.
  $options = array(
    'field_id' => $instance['field_id'],
    'deleted' => TRUE,
  );
  _field_invoke('delete', $entity_type, $entity, $dummy, $dummy, $options);

  // Tell the field storage system to purge the data.
  module_invoke($field['storage']['module'], 'field_storage_purge', $entity_type, $entity, $field, $instance);

  // Let other modules act on purging the data.

    $function = $module . '_field_attach_purge';
