Drupal 6 field instances source from database.

Available configuration keys:

  • node_type: (optional) The content type (machine name) to filter field instances retrieved from the source. If omitted, all field instances are retrieved.

Example:


source:
  plugin: d6_field_instance
  node_type: page

In this example field instances of type page are retrieved from the source database.

For additional configuration keys, refer to the parent classes.

Plugin annotation


@MigrateSource(
  id = "d6_field_instance",
  source_module = "content"
)
