For example, I have a custom post type that displays a video. That video is also a custom post type with custom fields. In order to associate the video with the post, I have a field called ‘video’ that is a Post Object. That way, I can just pick the video in a list to display on that post.
When I upgraded the plugin, the videos just stops showing up. When I revert the plugin, they work again. Actually, anything using a Post Object field – which there are quite a bit (Sliders, featured items…).
With 5.1.8 this will return a Post Object:
$post = get_post(60);
echo $post->post_title;
$fields = get_fields(60);
$video_post_object = $fields['video'];
$field = get_field('video', 60);
print_r($video_post_object); // WP_Post Object ( [ID] => 926 ... )
print_r($field);
In 5.2.X the video field is blank/null/whatever.
Field Name: video
Field Type: Post Object
Required: No
Filter by Post Type: Video
Filter by Taxonomy: –
Allow Null? No
Select Multiple? No
Return Format: Post Object
Conditional Logic: No
Video is one example, but all Post Objects return null with get_field/get_fields.
I should also note, the field groups are currently being setup in the admin section under the Custom Fields tab – so ACF is driving all of this.
