function FieldDefinitionInterface::getTargetBundle

Gets the bundle the field is attached to.

This method should not be confused with EntityInterface::bundle() (configurable fields are config entities, and thus implement both interfaces):

• FieldDefinitionInterface::getTargetBundle() answers "as a field, which bundle are you attached to?".
• EntityInterface::bundle() answers "as a (config) entity, what is your own bundle?" (not relevant in our case, the config entity types used to store the definitions of configurable fields do not have bundles).

Return value

string|null The bundle the field is defined for, or NULL if it is a base field; i.e., it is not bundle-specific.
