Home Forums Backend Issues (wp-admin) Set image as featured image Reply To: Set image as featured image

  • I know this is an old topic, but after doing this for some time I’ve just recently realized that using a filter isn’t needed. All you really need to do is create an image field with the field name of “_thumbnail_id”, and ACF will just update the featured image for you. There’s no error checking, but simply making your image field required deals what that problem.
