Meta Box

Hi,

Thanks for reply.

Actually the problematic field is not the image-advanced type, but the single_image type. It corresponds to the field I have named "dlc_media_photos_couverture". Can you help me with this one ?

I will, nevertheless try your suggestion concerning the other type of field.

Hi,

This the PHP code generated through the WP back-office builder. All fields can be succesfully pulled, apart from the single image "dlc_media_photos_couverture".

FYI "dlc_media_photos_choix" corresponds to an Advanced Image field, where we can upload a gallery of images.
