I used get_comment() but its parameter is $comment_ID which I has to enter manually for previous comments from wp_comments instead of that I need to get current comment means last updated comment author name based on the post_ID. However wp_posts and wp_comments are related with post_ID and comment_post_ID, so I can use SQL query to get comment_ID I tried $wpdb->get_results('select comment_ID from wp_comments where comment_post_ID = 1') its even manual process but at-least I want to pass comment_ID by fetching from database but could't do that query results nothing so is there any way to get current comment_ID for a post_ID I can get post_id by $post->ID.

Use get_comments( $args ) to get all the comments for a post.

$args= array(
    'author_email' => '',
    'ID' => '',
    'karma' => '',
    'number' => '',
    'offset' => '',
    'orderby' => '',
    'order' => 'DESC',
    'parent' => '',
    'post_id' => 0,
    'post_author' => '',
    'post_name' => '',
    'post_parent' => '',
    'post_status' => '',
    'post_type' => '',
    'status' => '',
    'type' => '',
    'user_id' => '',
    'search' => '',
    'count' => false,
    'meta_key' => '',
    'meta_value' => '',
    'meta_query' => '');

You can set post_id here and get all comments related to that post. It is same as your query.

$comments = get_comments(array('post_id'=> 'your post id'));
$comment_ids = array();
foreach($comments as $comment):
    $comment_ids[] = $comment->comment_ID;
print_r($comment_ids); // edite print_r(comment_ids);

For reference http://codex.wordpress.org/Function_Reference/get_comments

  • I need to get comment author name when ever a new comment is generated for a particular post, although may be I could get the same from get_comments() function if I could access last comment, means highest comment_ID for particular post_id THANKS

  • You can use orderby value as comment_date_gmt for get latest comment at top. After getting its 0 element you get latest comment. Then comment->comment_author will give you author name for latest comment :)
