Figure I should start with the goal. Maybe I am going about what I am trying to do the wrong way.
I want to store the thumbnail of an oembed's $data in a separate post_meta. I don't want to overwrite or change the original _oembed_MD5 stored in the post_meta.
I've looked through the codex and also the source at oembed_dataparse & oembed_result. But when I try to access
global $post nothing is returned. I mainly need the $post->ID so I can update_post_meta($post->ID, 'oembed_thumb', $oembed_thumbnail);
So I am wondering is it possibly a priority issue where it should be higher or lower than 10(the default)?
Should I be using a different hook/filter.
I was thinking I could add in a hook for post_save set a global var for
$oembed_thumb = $data->thumbnail and when the oembed_dataparse happens reference the global $oembed_thumb. But I think that is pretty janky.
Hopefully my explanation is clear.
