Provides the display for a field

This function corresponds to the hook_field_formatter_view() function of the Drupal Field API.

This function provides the display for a field when it is viewed on the web page. The content returned by the formatter should only include what is present in the $items[$delta]['values] array. This way, the contents that are displayed on the page, via webservices and downloaded into a CSV file will always be identical. The view need not show all of the data in the 'values' array.

Parameters

$element:

$entity_type:

$entity:

$langcode:

$items:

$display:

Return value

An element array compatible with that returned by the hook_field_formatter_view() function.
