Fires when Drupal checks whether a user can access a specific field on an entity. This wraps Drupal's hook_entity_field_access().

Use the Set access result action to grant or deny access.

High frequency event

This event fires for every field on every entity during page rendering. Always use specific filters (entity type, bundle, field name, operation) to narrow matches and avoid performance issues.

Note: Field access operations are view and edit (not update/delete as with entity-level access).

Fields

For any successor of this event, the account that asks for access is available under the <strong>[account]</strong> token. Example: <strong>[account:uid]</strong> provides the user ID of the account.

Furthermore, following data of the event is available:<ul><li><strong>[event:operation]</strong> holds the requested operation, such as "view".</li><li><strong>[event:field]</strong> holds the machine name of the field.</li></ul>

Restrict by entity type ID

Example: node, taxonomy_term, user

Restricts to the specified entity type (e.g., node, taxonomy_term). Comma-separated for multiple values.

Restrict by entity bundle

Example: article, tags

Restricts to the specified bundle (e.g., article, tags). Comma-separated for multiple values.

Restrict by operation

Example: view, edit

Restricts to the specified operation. For field access, the operations are view and edit (not update or delete).

Restrict by field name

Example: title, body, field_myfield

Restricts to the specified field machine name (e.g., title, body, field_image). Comma-separated for multiple values. Highly recommended to set this to avoid triggering on every field access check.
