Use conditions and the appropriate validation actions to add violation messages that will prevent the entity from being saved.

Fields

Type (and bundle) — config key: type

Type: select · Required: no · Default: _all

Allowed values depend on the configuration of the target site.

Value format: <entity_type_id> <bundle>, space separated. Use _all as a wildcard in either position.

This field provides a list with all created content entities and its bundles. You can also select -any-, if you want to react to all types or bundles. In configuration, the value is a single string holding the entity type ID and the bundle separated by one space, for example node article, where the wildcard _all stands for -any- in either position. See Authoring models as configuration.
