I know this is an old post and I have actually submitted a new post https://support.advancedcustomfields.com/forums/topic/using-publish_posttype-to-get-acf-fields/ in regards to using the publish action with custom post type. I am not able to use $_POST to get the acf values and using acf/save_post only get’s acf fields not wordpress fields like post title and post content. Would it be save to assume that I just need replace all of wp fields like the post title and post content editor with an acf fields?
