Select translation

Description

Select translation implements a Views filter to select which translation of a node should be displayed in a list of nodes.

Several modes are available to select a translation:

• Use the current interface language; if not available use the original node language.
• Use the current interface language; if not available use the default site language; if not available use the original node language.
• Specify a list of languages, and use the most appropriate language.
  
  Some special values are recognized in the languages list:
  • "current" will be replaced with the current interface language;
  • "default" will be replaced with the default site language;
  • "original" will be replaced with the original node language.

Select translation also provides an API following the same selection algorithm as the Views filter.

Drupal 6 Compatibility

Select translation works with Content translations (not Entity translations).

If you have i18n, you should set 'Content selection mode' to 'All content' in i18nsettings (admin/settings/i18n).

API

Given a node id, and a selection mode, the function returns the node id to display.

Example:

  <?php
  $my_nid = select_translation_of_node($nid); // Uses 'default' mode
  $my_nid = select_translation_of_node($nid, 'original'); // Uses 'original' mode
  $my_nid = select_translation_of_node($nid, array('en', 'fr', 'current')); // Returns the best match
  ?>

Similar project : Active translation performs a similar function but it is not a Views filter - it acts on all queries of the whole site.

Drupal 7

Select translation starts using an optimized query for the Views filter plugin.

Drupal 8

Select translation works on Entity translations.

Since in Drupal 8 any node always have at least one "translation" (the original one), the include_content_without_translation option has been removed.

API

Given a node id, and a selection mode, the function returns the entity translation.

Example:

  <?php
  use Drupal
odeEntityNode;

  /* @var Drupal
odeEntityNode $my_node */
  $my_node = select_translation_of_node($nid); // Uses 'default' mode
  $my_node = select_translation_of_node($nid, 'original'); // Uses 'original' mode
  $my_node = select_translation_of_node($nid, 'en,fr,current'); // Returns the best match
  ?>
