comments_number() │ WP 0.71

Display the number of article comments and specify what text to display, with a certain number of comments.

Comment count zero – no comments yet; comment count one – one comment; more than one comment (total 42) displays 42 comments.

<p>
This post has <?php comments_number( 'no comments yet', 'one comment', '% comments'); ?>.
</p>

Let's display a link to comments for each post announcement on the category page, where the anchor of the link will be the number of post comments:

<a href="<?php the_permalink() ?>#comments">
	<?php comments_number( 'no comments', '1 comment', '% comments'); ?>
</a>

You might want to have a title above your comments section that includes the number of comments. This example shows how to do that and have all the strings also be translatable.

<h3>
<?php
printf(
	_nx( 'One Comment', '%1$s Comments', get_comments_number(), 'comments title', 'textdomain' ),
	number_format_i18n( get_comments_number() ) 
);
?>
</h3>

add_filter( 'comments_number', 'wporg_com_num', 10, 2 );

function wporg_com_num ( $out, $num ) { 

	if ( 0 === $num ) { 
		$out = '0 Comments';
	}
	elseif ( 1 === $num ) {
		$out = '1 Comment'; 
	}
	else {
		$out = "{$num} Comments";
	}

	return $out;
}

The use of _n() can simplify the above function definition to one line:

return _n( '1 Comment', "{$num} Comments", $num );
