Faceted search and i18n under Drupal 5

Upon further inspection, I read in the documentation that Faceted search should work with i18n. In Site Configuration>Multilingual System>Translation, all vocabularies are checked, (so that they are translated by the localisation system), but still the vocabulary names are not translated. (The terms are translated though).

Has anybody got any ideas?

Thanks,

A Burton

Thanks for your swift reply. We are stuck with Drupal 5 for the moment because some of the modules we use have not yet been updated to Drupal 6. I will try and see if I can find a solution by studying the i18ntaxonomy, i18nstrings and faceted search modules. If anyone has any ideas or could help me, it would be most appreciated. I'm a bit surprised that no one else has had the same problem.

Thanks again,

A Burton

I found a solution by intercepting the facted search object and translating the vocabulary name before the block is created.
David, you said:

t() is not meant to be used with user data, which means it won't be added to Faceted Search for localizing term or vocabulary names.

but for me vocabulary names are not user data. Could you please explain? Terms don't need to be localized as they are translated by the i18n module.

Anyway here is the modification I did to the hook_block implementation faceted_search_ui_block in the file faceted_search_ui.module. I have commented the modified lines. Please note, I started this post for version 5.x-1.0-beta4 but the following modif does not work for that version. We decided to stay with the 5.x-0.11 for which this modif works. Sorry, but I don't know how to make a patch. Any comments would be appreciated.

  }
}

Same modification in function faceted_search_ui_stage_facet() which is called when there are too many categories to display and we click on "more...". There are probably other places where the fix has to be made, but for us it is sufficient at least until we can upgrade to version 6.

/**

  global $_faceted_search_ui_current_search;

  # copy faceted search object to avoid manipulating the original...
  $_faceted_search_ui_current_search_copy = drupal_clone($_faceted_search_ui_current_search);

  # translate the vocabulary name...
  foreach($_faceted_search_ui_current_search_copy->_facets as $facet) {

  }

  faceted_search_ui_add_css();
  faceted_search_ui_add_tooltips();
  
  // Build the search results, which are required to count nodes per category
  $_faceted_search_ui_current_search_copy->execute();

  // Find what facet to show
  list($index, $facet) = $_faceted_search_ui_current_search_copy->get_facet_by_id($_faceted_search_ui_current_search_copy->ui_state['facet-key'], $_faceted_search_ui_current_search_copy->ui_state['facet-id']);
  if (!isset($index) || !isset($facet)) {
    drupal_not_found();
    return;
  }

  faceted_search_ui_set_title($_faceted_search_ui_current_search_copy);
  $categories = faceted_search_ui_build_categories($_faceted_search_ui_current_search_copy, $index); // TODO: paging
  return theme('faceted_search_ui_stage_facet', $_faceted_search_ui_current_search_copy, $index, $facet, $categories);
}

OK, thanks. I think it will be alright because we have only have 15 vocabulary names to be translated with t(). Thanks again for you time,
