function hook_field_extra_fields_display_alter

Alters the display settings of pseudo-fields before an entity is displayed.

This hook is called once per displayed entity. If the result of the hook involves reading from the database, it is highly recommended to statically cache the information.

Parameters

$displays: An array of display settings for the pseudo-fields in the entity, keyed by pseudo-field names.

$context: An associative array containing:

  • entity_type: The entity type; e.g., 'node' or 'user'.
  • bundle: The bundle name.
  • view_mode: The view mode, e.g. 'full', 'teaser'...
