Using publish_posttype to get acf fields

I am working on a feature, that when a post for my custom post type is first published it will retrieve both WP fields like post_title and my custom acf fields. I have tried acf/save_post but this is only getting the acf fields and I need wordpress fields too. I’ve tried using get_post_meta and currently working with getting the acf fields via $_POST. If basically kill my function and dump all the variables I can see all the data. But when capturing the $_POST in a variable it’s returning NULL. I should also mention that I am capturing the fields to pass to an xml file using simpleXML. The xml file is getting generated and I can see all the normal WP fields just can’t seem to capture any of the ACF stuff. Here is all of my logic that I am using:

public function generateDataXML($ID, $post)
    {
        $upload = wp_upload_dir();
        $upload_dir = $upload['basedir'];
        $upload_dir = $upload_dir . '/events';

        if ( ! file_exists( $upload_dir ) ) {
            wp_mkdir_p( $upload_dir );
        }

        $xml = new \SimpleXMLElement('<rss xmlns:g="http://base.google.com/ns/1.0" />', LIBXML_NOERROR, false, 'g', true);
        $xml->addAttribute('version', '2.0');

        $channel = $xml->addChild('channel');
        $channel->addChild('title', get_bloginfo('name'));
        $channel->addChild('link', get_bloginfo('url'));
        $channel->addChild('description', get_bloginfo('description'));

        $eventID = $post->ID;
        
        $postName = $post->post_name;
        $posttitle = $post->post_title;
        $abspath = get_site_url();

        
        if (get_post_status($eventID) == 'publish') {
            //Web Data Tab
            //If no Artist Name then will capture Event Name
            $artistNameID = $_POST['acf']['field_5f223fa5381da']['field_5f223fd2381db'];
            $artistNamePost = get_post($artistNameID);
            $artistName = $artistNamePost->post_title;
            $primaryGenre = get_post_meta($artistNameID, 'genres_primary_genre', true);
            $secondaryGenre = get_post_meta($artistNameID, 'genres_secondary_genre', true);
            $eventName = $posttitle;
            $eventDate = $_POST['acf']['field_5f2241e2c0bf4']['field_5f224203c0bf5'];
            $doorsOpen = $_POST['acf']['field_5f2241e2c0bf4']['field_5f2242b5c0bf7'];
            $eventImageArray = intval($_POST['acf']['field_5f2241e2c0bf4']['field_5f245777ac9b5']);
            $image = wp_get_attachment_image_src($eventImageArray, 'full');

            //die(var_dump($_POST['acf']['field_5f2241e2c0bf4']));

            //Campaing Data
            //If Campaign Data has data fields not null it will use this instead of web data
            $campaignArtistName = intval(get_post_meta($eventID, 'artist_info_ad_campaign_artist_name_ad_campaign'));
            $campaignEventName = get_post_meta($eventID, 'show_info_ad_campaign_event_name_ad_campaign');
            $campaignEventDate = get_post_meta($eventID, 'show_info_ad_campaign_date_of_event_ad_campaign', true);
            $campaignDoorsOpen = get_post_meta($eventID, 'show_info_ad_campaign_doors_open_time_ad_campaign', true);
            $campaignEventImageArray = get_post_meta($eventID, 'show_info_ad_campaign_show_event_image_ad_campaign', true);
            $campaignImage = wp_get_attachment_image_src($campaignEventImageArray, 'full');

            $eventRow = $channel->addChild('item');
            $eventRow->addAttribute("id", $postName.'-'.$eventID);
            $eventRow->addChild("g:g:title", htmlspecialchars($posttitle));

            if ($artistNameID) {
                $eventRow->addChild('g:g:artist', $artistName);
            } else {
                if (!empty($campaignEventName)) {
                    $eventRow->addChild('g:g:event', $campaignEventName);
                } else {

                }

The post fields that you’re talking about are not fields but data in the post table. When using acf/save_post you need to $post = get_post($post_id) and then access the post information from there like $title = $post->post_title. Or you can skip getting the post and use something like $title = get_the_title($post_id)
