Untranslatable strings "Order total"

If I'm not mistaken, it's because these items are coming from fields. Their labels would need to be translated using some sort of field translation module.

You need the i18n_fields module.

Can you please post a screenshot of what you're talking about?

Ok, that part of the page is generated by the Price field display formatter called "Formatted amount with components".

The particule code comes from commerce_price_field_formatter_view around line 439:

        // Add the actual field value to the array.
        $components['commerce_price_formatted_amount'] = array(
          'title' => check_plain($instance['label']),
          'price' => $item,
          'weight' => $weight + 1,
        );

Notice that it's just using the label of the Price field instance, in particular the Order Total price field attached to orders. I'd expect you to be able to translate this label like any other field label with i18n_fields. Is this not the case?

The field label cannot (and should not) be translated by Drupal core since D7.2.

See issue #1157426: Field system uses t() incorrectly and inconsistently for Drupal core and #1157512: Labels are not translated with i18n_field for Drupal core. for a fix that will be added to the Internationalization module.

Also, duplicate of #1121722: Improve DX of instance translation.

I found this alternative : http://www.drupalons.fr/node/5247
It's works for me.

/*
*  Implements hook_themet_commerce_price_formatteed_components().
*  Fix Order total for drupal commerce.
*/
function yout_theme_commerce_price_formatted_components($vars) {
  $vars['components']['commerce_price_formatted_amount']['title'] = t('Montant Total');
  return theme_commerce_price_formatted_components($vars);
}

I can't get the field label "Order total" translated. the sceenshot 1 is what it looks like when I search "Order total" as a field. And when I click on edit, I got the page as screenshot 2, with no filed shown up for me to enter the translation I want.

Did I miss anything or did it wrong?

Really want to get the issue fixed. All other fields and the module work great after all.
