I am implementing comment function by AJAX. At the moment wp insert post is used. However, this function does not have a key for entering three values of “reply attribute”.

In other words, I want to input three values “forum ID”, “topic ID” and “Reply To ID” with wp insert post.

It key is like the next “???” .

wp_insert_post(array(
    'post_title'   => (string)$_POST['replyTitle'],
    'post_content' => (string)$_POST['replyContent'],
    'post_status'  => 'publish',
    'post_author'  => get_current_user_id(),
    'post_type'    => 'reply'
    '???'          => (string)$_POST['forumID'],
    '???'          => (string)$_POST['topicID'],
    '???'          => (string)$_POST['replyToID'],
), true);

How can I register these three values with wp insert post?

I look forward to your response.
