Hello,

My website has MetaBox and WPML installed, with English as the primary language and German as the secondary language.

I have the ID of the German version of the post type "merchant". I thought I would be able to get a field value of that post with the below code. Both the post type and field are translatable in WPML, and have been translated.

$merchant_name = rwmb_get_value( 'content_long_title', '', $postID );

But that returns nothing.

This returns the expected German value:
```
$postIDde = apply_filters( 'wpml_object_id', $postID, 'merchant', false, 'de');
$merchant_name = get_post_meta( $postIDde, 'content_long_title', true);
```
This returns nothing either:
```
$postIDde = apply_filters( 'wpml_object_id', $postID, 'merchant', false, 'de');
$merchant_name = rwmb_get_value( 'content_long_title', '', $postIDde );
```
Can rwmb_get_value not deal with fields that have been made translatable with WPML? If there is a way to make it work, please let me know.

Hi Arno,

I do not see any issue when using the helper function rwmb_get_value() to display the translation field value on the frontend. But you can try to use the helper function rwmb_meta() in this case.

See how it works on my demo site https://monosnap.com/file/Tbj5Hc91OgrVMusrk2BW7oQ4WzNCKb

Steps to reproduce:
- Go to WPML > Settings > Enable translate for the field content_long_title
- Translate the post and field value
- Add this code to the post template to display the field value
```
$content_long_title = rwmb_meta( 'content_long_title' );
echo 'content_long_title: ' . $content_long_title;
```

Hi Long,

Great, rwmb_meta works for me. I can pass the original post ID, so I don't need to request the translated post ID first. That's one less line of code 🙂 I'm not sure why rwmb_get_value() only works for English in my case.

Thanks!
