How to show the comment count for a certain WordPress post using a shortcode

Just add this WordPress Code Snippet to the functions.php file in your current WordPress theme in order to show the comment count for a certain WordPress post using a shortcode.

/**
 * Get post comment count using shortcode
 *
 * @author WPSnacks.com
 * @link https://www.wpsnacks.com
 */
function comment_shortcode($atts) {
	extract( shortcode_atts( array(
		'id' => ''
	), $atts ) );

	$num = 0;
	$post_id = $id;
	$queried_post = get_post($post_id);
	$cc = $queried_post->comment_count;
		if( $cc == $num || $cc > 1 ) : $cc = $cc.' Comments';
		else : $cc = $cc.' Comment';
		endif;
	$permalink = get_permalink($post_id);

	return '<a href="'. $permalink . '" class="comments_link">' . $cc . '</a>';

}
add_shortcode('comments', 'comment_shortcode');

Then just use this shortcode in your content to display the comment count for a certain post:

[comments id=”20″]

Replace the 20 above with the ID of the post you want to show the comment count from.
