Multilingual Breadcrumb

Question

I need to show a breadcrumb on my client website but it is required to be in two languages I have tried several approaches and modules but all of it show the breadcrumb in one language only.

Please, If anyone have an idea about this I appreciate your help.

Besides, Could you please explain more about using default drupal breadcrumb what should I have been installed to use breadcrumb correctly? Do I need breadcrumb + another module ???

Regards,

Answer 1

Assuming you want your breadcrumbs like this:

  Home/La Casa >> Node/Nodo >> Friends/Amigos

You could override template_preprocess_breadcrumb like so:

  function MY_THEME_preprocess_breadcrumb(&$variables)
  {
     $breadcrumbs = &$variables['breadcrumb'];
     foreach($breadcrumbs as &$breadcrumb)
     {
         $breadcrumb .= '/' . locale($breadcrumb, null, 'SP');
     }
   }

Don't quote me on the langcodes, and this would require that you have the locale module installed and enabled, but it should output the above example breadcrumb.

I used Custom Breadcrumbs Module it has the ability to add breadcrumb for each language... For breadcrumbs which are automatically generated translation can be done in String Translation Table. I think multilingual breadcrumb can also be created using Path Breadcrumbs

Answer 3

Drupal has some mainstream contributed modules that can handle this in most cases. Using built-in interface translation and i18n_string, you can add translations for many of the main breadcrumbs in Configuration -> Regional & Language -> Translate Interface -> Translate.

Several modules can help you get these strings to begin with. You can use the potx module to pull all built-in interface strings from your other installed modules, which puts the strings into the locales_source table. Then you can use the l10n_update module to search for community-contributed translations for these strings.

For the last part of a breadcrumb that comes from a node, for example, Drupal will display the translated title of the node if it finds it. For Content Translation (node-based), the node displays its title in the breadcrumb, and for Entity Translation (field-based), you can enable the title module to convert the title property to a field, which can then be translated and displayed in the breadcrumb.

Hope this helps:

<?php
    //breadcrumb fix
        function THEME_NAME_menu_breadcrumb_alter(&$active_trail, $item) {
            global $language ;
            $lang_name = $language->language;
            $i = 0;
            foreach (array_keys($active_trail) as $key) {
                if($i!=0){
                    $translatedValue = i18n_string_translate(array('menu', 'item', $active_trail[$key]['mlid'], 'title'), $active_trail[$key]['title'], array('langcode' => $lang_name, 'sanitize' => FALSE));
                    $active_trail[$key]['title'] = $translatedValue;
                }
               $i++;
            }
        } 
    ?>

Assuming you are using the i18n module, including submodule i18n_menu, then the most reliable way of translating your breadcrumbs would be implementing hook_menu_breadcrumb_alter and run _i18n_menu_link_title function on each item.

This should work:

/**
 *   Implements hook_menu_breadcrumb_alter()
 */
function YOURMODULE_menu_breadcrumb_alter(&$active_trail, $item) {
  foreach ($active_trail as $index => $breadcrumb_item) {
    if (isset($breadcrumb_item['mlid'])) {
      $active_trail[$index]['title'] = _i18n_menu_link_title($breadcrumb_item);
    }
  }
}
