Comment count next to post title?

Question

is there a simple way like a hook or function extension to show the comment count next e.g. behind the post title.

I'd like to show the comment count behind every post shown on my WordPress.

Example: Newspost on Intel (3)

...where (3) is the comment count of the post.

Any hint would be great!

Answer 1

On most cases you should be able to use the_title filter to modify the title string. Use get_comments_number() to get the comments count for the post - of given ID or the current one.

For example,

add_filter( 'the_title', 'wpse_427277_the_title', 10, 2 );
function wpse_427277_the_title( string $title, $post_id = null ): string {
    $comment_count = (int) get_comments_number( $post_id );
    if ( $comment_count ) {
        $title .= sprintf( ' (%d)', $comment_count );
    }

    return $title;
}

Modify as needed.

    <?php if( comments_open( get_the_ID() ) ) : ?>
                        <a href="<?php the_permalink(); ?>#comments" class="comments-link"><i class="fa fa-comment"></i> <?php echo en2fa( get_comments_number() ); ?></a>
                    <?php endif; ?>
