field_attach_view

7 field.attach.inc field_attach_view($entity_type, $entity, $view_mode, $langcode = NULL)

Returns a renderable array for the fields on an entity.

Each field is displayed according to the display options specified in the $instance definition for the given $view_mode.

field_attach_prepare_view() and field_attach_view() are two halves of the same operation. It is safe to call field_attach_prepare_view() multiple times on the same entity before calling field_attach_view() on it, but calling any Field API operation on an entity between passing that entity to these two functions may yield incorrect results.

Sample structure:

array(
  'field_foo' => array(
    '#theme' => 'field',
    '#title' => the label of the field instance,
    '#label_display' => the label display mode,
    '#object' => the fieldable entity being displayed,
    '#entity_type' => the type of the entity being displayed,
    '#language' => the language of the field values being displayed,
    '#view_mode' => the view mode,
    '#field_name' => the name of the field,
    '#field_type' => the type of the field,
    '#formatter' => the name of the formatter,
    '#items' => the field values being displayed,
    // The element's children are the formatted values returned by
    // hook_field_formatter_view().
  ),
);

Parameters

$entity_type: The type of $entity; e.g. 'node' or 'user'.

$entity: The entity with fields to render.

$view_mode: View mode, e.g. 'full', 'teaser'...

$langcode: The language the field values are to be shown in. If no language is provided the current language is used.

Return value

A renderable array for the field values.
