Drupal language source from database.

Available configuration keys:

  • fetch_all: (optional) If not empty, all source languages are retrieved and available as "languages" source property. Each language is an array with the same structure as a source row.
  • domain_negotiation: (optional) If not empty and domain negotiation is enabled in the source database, the "domain_negotiation_used" source property is set to TRUE.

Example:


plugin: language
fetch_all: true
domain_negotiation: true

In this example, available languages are retrieved from the source database. Given that fetch_all and domain_negotiation are specified, each row also contains all languages and the domain negotiation status, if enabled.

For additional configuration keys, refer to the parent classes:

Plugin annotation


@MigrateSource(
  id = "language",
  source_module = "locale"
