There are many WordPress themes that don’t show numbers on comments but we use them because they are better on other sides. So here I am discussing how to easily add numbers in your WordPress theme’s comments section.
Locate the comments.php file.
Find start of the comment loop. Something like this:
<?php if ( $comments ) : ?>
Add following code immediately above the above given code:
<?php $i = 0; ?>
Find the code that looks like this:
<?php foreach ($comments as $comment) : ?>
Placed following code immediately below the code in the above step:
<?php $i++; ?>
Use following code where you want to display your comment numbers:
<?php echo $i; ?>
Now click Save.
Open your theme’s stylesheet (style.css) and place following code anywhere on the stylesheet:
You can adjust CSS to fit your comment numbers in the placement and appearance that you like to have.
