Frontend: create post and comment with custom fields

  • Hello,
    I need to create a post and the first comment with metadata from the frontend.
    It is a review website where people can add a product generic info sheet (product post type), and their multi-criteria rating (comment).

    I am using ACF and ACF Frontend Form for Elementor.
    I created two ACF fields groups:
    – one for the ratings / comments
    – one to create a new product AND the very first rating.

    I managed to create new posts, comments alone work fine,
    but I cannot add my ACF fields to the first comment when the post is created.

    I tried this code in functions.php:

    function my_acf_comment_meta ( $post_id ) {
    	$meta1 = get_field('form_meta_1');
    	$current_user = wp_get_current_user();
    	$agent = $_SERVER['HTTP_USER_AGENT'];
    	$ip = $_SERVER['REMOTE_ADDR'];
        $com_meta = array(
            "comment_meta_1" => $meta1,
            "comment_meta_2" => 'Lorem ipsum',
    	$data = array(
    		'comment_post_ID' => $post_id,
    		'comment_author' => $current_user->display_name,
    		'comment_author_email' => $current_user->user_email,
    		'comment_content' => $comment,
    		'comment_agent' => $agent,
    		'comment_author_IP' => $ip,
    		'comment_date' => date('Y-m-d H:i:s'),
    		'comment_date_gmt' => date('Y-m-d H:i:s'),
    		'comment_approved' => 1,
    		'comment_meta' => $com_meta,
    	$comment_id = wp_insert_comment($data);
    add_action('acf/save_post', 'my_acf_comment_meta', 99);

    This way I can add a comment with only the static value of comment_meta_2,
    but comment_meta_1 is empty, instead of showing the value of my frontend form field form_meta_1 .

    If don’t push my fields in the comment array but I try

    $meta1 = get_field('form_meta_1');
    add_comment_meta($comment_id, 'comment_meta_1', $meta1);

    add_comment_meta($comment_id, ‘comment_meta_2’, ‘Lorem ipsum’);`
    I get the very same result: static data is stored in the comment, ACF data is not.
    Any ideas? Thank you in advance

  • First thing you need to do is install and activate the WordPress Comments Fields. Upon activation, the plugin will add a new menu item labeled ‘Comments Fields’ in your WordPress menu.
