[Closed] add_attachment not called when media is duplicated

Hi there,

Thank you for contacting WPML support. While you are waiting for one of my colleagues to take this ticket and work on it, let me provide you with the first debugging steps or if I can help with the issue quickly.

I understand that the add_attachment hook (https://developer.wordpress.org/reference/hooks/add_attachment/) is only triggered for the original language's attachment after uploading it in the media library. You believe it should be triggered for every attachment in every language.

Did I get that right?

If you let us know your goal, we can check if WPML can help with a hook (something like: https://wpml.org/wpml-hook/wpml_apply_save_attachment_actions/). If it's a bug, we can escalate it to our developer.

Looking forward to hearing back from you.

Hi David,

Thank you for contacting WPML support, I'd be happy to help you with this issue.

I can see that issue on my demo site. I think there is a workaround by using the filter hook "wpml_object_id" to get the translation attachment ID. For example:

add_action( 'add_attachment', function( $post_id ) {
	error_log ( 'Image id: ' . $post_id );
	$translated_post_id = apply_filters( 'wpml_object_id', $post_id, 'attachment', false, 'fr');
	error_log ( 'Image id FR: ' . $translated_post_id );
});

You will see the translation attachment ID in the debug log. Refer documentation https://wpml.org/wpml-hook/wpml_object_id/

Look forward to your reply.
Thanks

Hi,

The filter "wpml_post_duplicates" works when you duplicate a post/page into second languages. It does not work with media items in this case.

the problem is I do not know ahead of time the language to use. And the site may have more than one language.

Then you can use the filter hook "wpml_active_languages" to get all active languages on your site and use the filter hook "wpml_object_id" above to get translation attachment ID based on the languages.
Refer to the documentation https://wpml.org/wpml-hook/wpml_active_languages/

Look forward to your reply.
Thanks
