The comments_per_page hook in WordPress is used to modify the number of comments displayed per page on a WordPress site. This hook allows developers to customize the pagination of comments on their website.
Understanding the Hook: comments_per_page
The comments_per_page hook is located within the WordPress comments template file. It is used to control the number of comments displayed per page on a post or page. By default, WordPress displays a set number of comments per page, but this hook allows developers to change that number according to their specific needs.

The comments_per_page hook does not accept any parameters. It simply allows developers to modify the default number of comments displayed per page.
Hook Doesn’t Work: comments_per_page
If the comments_per_page hook doesn’t work as expected, it may be due to conflicts with other plugins or themes that also modify the comments pagination. To troubleshoot, developers should deactivate other plugins and switch to a default WordPress theme to see if the issue persists. Additionally, checking for syntax errors in the code implementing the hook is recommended.
Best Practices & Usage Notes (if applicable): comments_per_page
When using the comments_per_page hook, developers should consider the impact on user experience and page load times. Displaying a large number of comments per page can slow down the website, so it’s important to find a balance between displaying enough comments for engagement and maintaining site performance.

“`php
function custom_comments_per_page( $comments_per_page ) {
return 10; // Change the number of comments per page to 10
}
add_filter( ‘comments_per_page’, ‘custom_comments_per_page’ );
“`
