Displaying recent comments on your blog, lets your visitors know about the recent comments on your blog and also encourages them to make comments.

Though “Recent Comments” does not come as a default widget with WordPress, there are many plugins available for this functions. But if you don’t want to install anymore plugins, then here is the simple code snippet for you.

<?php
global $wpdb;
$sql = “SELECT DISTINCT ID, post_title, post_password, comment_ID, comment_post_ID, comment_author, comment_date_gmt, comment_approved, comment_type,comment_author_url, SUBSTRING(comment_content,1,30) AS com_excerpt FROM $wpdb->comments LEFT OUTER JOIN $wpdb->posts ON ($wpdb->comments.comment_post_ID = $wpdb->posts.ID) WHERE comment_approved = ’1′ AND comment_type = ” AND post_password = ” ORDER BY comment_date_gmt DESC LIMIT 10“;

$comments = $wpdb->get_results($sql);
$output = $pre_HTML;
$output .= “\n<ul>”;
foreach ($comments as $comment) {
$output .= “\n<li>”.strip_tags($comment->comment_author) .”:” . “<a href=\”" . get_permalink($comment->ID).”#comment-” . $comment->comment_ID . “\” title=\”on “.$comment->post_title . “\”>” . strip_tags($comment->com_excerpt).”</a></li>”;
}
$output .= “\n</ul>”;
$output .= $post_HTML;
echo $output;
?>

Just place this code, wherever you want to show recent comments, may be your sidebar.

This code will list the 10 most recent comments. If you want to list more or less comments, simply change the “10″ in the $sql variable highlighted in red.

Thats it you are done.
