Extend format_value / missing ACF on attachments

Heya,

Currently we have two ACF values on attachments, when using: get_fields(); for a specific post these ACF values don’t get added.

As example, I have a post with ACF image fields when getting this post and all of its fields (get_fields($post_id)) it does not add the attachment custom values.

Is there a way of adding this info without having to hack into the image field / format_value function.

Ideal would be if I could add a filter that always gets all fields for each post and attachment and add this to the output.

Cheers,

Mark

The current output:

[0] => Array
    (
        [ID] => 433
        [id] => 433
        [alt] => 
        [title] => IMG_3499-3
        [caption] => 
        [description] => 
        [mime_type] => image/jpeg
        [type] => image
        [url] => /wp-content/uploads/2014/08/IMG_3499-3.jpg
        [width] => 1920
        [height] => 1280
        [sizes] => Array
            (
                [thumbnail] => /wp-content/uploads/2014/08/IMG_3499-3-150x150.jpg
                [thumbnail-width] => 150
                [thumbnail-height] => 150
                [medium] => /wp-content/uploads/2014/08/IMG_3499-3-640x426.jpg
                [medium-width] => 640
                [medium-height] => 426
                [large] => /wp-content/uploads/2014/08/IMG_3499-3-1024x682.jpg
                [large-width] => 640
                [large-height] => 426
            )
    )

Hi @marksmits,

I would recommend you make use of the object return type for the image fields, this would help in fetching the image array.

You can also checkout the get_field_objects() function which also returns an array of custom field objects for a specific page / post.

You can check it out here: http://www.advancedcustomfields.com/resources/get_field_objects/
