如何使用comment_post_form获取Comment-ID

Question

I´m searching for a way to hook into comment_post_form and update_comment_meta, if something, but i can´t figure out how to get the comment-ID.

The function is in the functions.php

function add_comment_drawing() {

    $drawingsave = $_POST['drawinginput'];
    if ($drawingsave == 'Das Bild wird gespeichert'){
    update_comment_meta(  $comment->ID, 'drawingurl', 'Brad' );
    }


 }
add_action('comment_post', 'add_comment_drawing');

Thanks in advance

Comment Actions:

comment_post
Runs just after a comment is saved in the database. Action function arguments: comment ID, approval status ("spam", or 0/1 for disapproved/approved).

function add_comment_drawing($comment_id){
    $drawingsave = isset($_POST['drawinginput']) ? $_POST['drawinginput'] : false;
    if($drawingsave == 'Das Bild wird gespeichert'){
        update_comment_meta($comment_id, 'drawingurl', 'Brad' );
    }
}
add_action('comment_post', 'add_comment_drawing', 10, 1);
