public function EntityViewBuilderInterface::viewField

Builds a renderable array for the value of a single field in an entity.

The resulting output is a fully themed field with label and multiple values.

This function can be used by third-party modules that need to output an isolated field.

• Do not use inside node (or any other entity) templates; use render($content[FIELD_NAME]) instead.
• The FieldItemInterface::view() method can be used to output a single formatted field value, without label or wrapping field markup.

The function takes care of invoking the prepare_view steps. It also respects field access permissions.

Parameters

\Drupal\Core\Field\FieldItemListInterface $items: FieldItemList containing the values to be displayed.

string|array $display_options: Can be either:

• The name of a view mode. The field will be displayed according to the display settings specified for this view mode in the $field definition for the field in the entity's bundle. If no display settings are found for the view mode, the settings for the 'default' view mode will be used.
• An array of display options. The following key/value pairs are allowed:
  • label: (string) Position of the label. The default 'field' theme implementation supports the values 'inline', 'above' and 'hidden'. Defaults to 'above'.
  • type: (string) The formatter to use. Defaults to the 'default_formatter' for the field type. The default formatter will also be used if the requested formatter is not available.
  • settings: (array) Settings specific to the formatter. Defaults to the formatter's default settings.
  • weight: (float) The weight to assign to the renderable element. Defaults to 0.

Return value

array A renderable array for the field values.
