Taxonomy Enum

This module allows you to synchronise taxonomy vocabularies with PHP enums. This is especially useful if you have a taxonomy vocabulary with a fixed set of terms and custom code that needs to behave differently based on which term is referenced. It basically allows you to reference a taxonomy term in code without having to hardcode ID's, which makes your code more portable between environments.

Features

• Automatically creates terms based on the enum cases
• Automatically deletes respective terms once enum cases have been removed (configurable)
• Disables the possibility to manually create/delete terms (configurable)
• Stores default field values in config as machine names instead of entity UUID's
• Allows you to get enum instances in custom code: $entity->get('some_taxonomy_enum_field')->enum
• Contains code to easily migrate existing entity reference fields: \Drupal::service('taxonomy_enum.migration')->migrateField('field_tags', 'node');
