How It Works

The Comments add-on works by querying an individual blog/single posts for user comments or reviews. Each comment and replies are returned using the familiar Ajax Load More infinite scroll / lazy load functionality.

By using a unique comment query, existing Ajax Load More functionality and core WordPress functions such as wp_list_comments, the Comments add-on is able to return post comments or WooCommerce reviews in an intuitive and user friendly format while helping improve the overall performance and user experience of your website.

Pro-Tip: You can also lazy load Comments using the Paging add-on Рview example.

Implementing comments with Ajax Load More is a two step process and will require modification of your single post template.

Step 1 – Select Comment Template or Callback Function

The first step will be to determine how you want Ajax Load More to display your comments – with the Comments add-on you can either select an existing callback function (from your theme) or create your own repeater template to handle the markup/display of your comments.

Comment Template

Creating your own custom template for displaying WordPress comments is a straight forward and intuitive process and is much like building a standard repeater template for Ajax Load More.

Simply construct a repeater template using HTML and standard WordPress comment functions such as comment_date() and comment_author() then select this template when building out a comment shortcode.


When building a custom comment template you should never close the opening HTML element – the closing </ li> is purposely left out of the template and will be closed by WordPress – View Gist

Callback Function

A comment callback is a function that is available from within a theme and is used to render and display each comment. When you enter a callback function name into the comments_callback shortcode parameter, Ajax Load More will attempt to render comments using this function.

The majority of premium and custom themes have callbacks for displaying comments. Please see comments.php or functions.php within your theme directory to locate the callback function for your theme – see the example below.

Callback Library

Below is a collection of comment callbacks referencing the theme/plugin and callback function.

  • WooCommerce: woocommerce_comments

Step 2 –¬† Adding Shortcode to Template

Locate your existing comments_template() function and replace it with an Ajax Load More comments shortcode and other comment related functions as seen in the code sample below.

In most cases you will be directly editing single.php but dependent on your theme you may need to edit another file – e.g. index.php.
