How to Load More Posts using Ajax with a Button or on Scroll in WordPress

When your WordPress website starts to grow with more content, displaying posts in a user-friendly way becomes critical. One of the most popular UI/UX features today is the ability to load more posts without reloading the page — either through a "Load More" button or infinite scroll.

In this blog, we'll break down everything you need to know to load more posts using AJAX in WordPress — with both button click and scroll options. This enhances user experience, improves page speed, and increases user engagement.

Let’s get started.

 Why Use AJAX to Load More Posts in WordPress?

AJAX (Asynchronous JavaScript and XML) allows your website to send and receive data from the server without refreshing the page.

Benefits:

•  Seamless user experience

•  Faster loading without full page reload

•  Ideal for mobile-first designs

•  Keeps visitors engaged longer

•  Helps with SEO when implemented properly

 Method 1: Load More Posts with a Button in WordPress (Using AJAX)

Step 1: Enqueue Scripts Properly

First, we’ll add our AJAX scripts in functions.php.

php

function load_more_posts_scripts() { wp_enqueue_script('ajax-load-more', get_template_directory_uri() . '/js/load-more.js', array('jquery'), null, true); wp_localize_script('ajax-load-more', 'ajaxloadmore', array( 'ajaxurl' => admin_url('admin-ajax.php'), )); } add_action('wp_enqueue_scripts', 'load_more_posts_scripts');

Step 2: Create the Load More Button in Template

Place this in your theme file where you want posts to appear.

php

<div id="post-container"> <?php $query = new WP_Query(array( 'post_type' => 'post', 'posts_per_page' => 5, )); if ($query->have_posts()) : while ($query->have_posts()) : $query->the_post(); get_template_part('template-parts/content', get_post_format()); endwhile; endif; wp_reset_postdata(); ?> </div> <button id="load-more">Load More</button>

Step 3: Add AJAX Handler in functions.php

php

function ajax_load_more_posts() { $paged = $_POST['page'] + 1; $query = new WP_Query(array( 'post_type' => 'post', 'posts_per_page' => 5, 'paged' => $paged, )); if ($query->have_posts()) : while ($query->have_posts()) : $query->the_post(); get_template_part('template-parts/content', get_post_format()); endwhile; endif; wp_reset_postdata(); die(); } add_action('wp_ajax_load_more', 'ajax_load_more_posts'); add_action('wp_ajax_nopriv_load_more', 'ajax_load_more_posts');

Step 4: JavaScript (load-more.js)

javascript

jQuery(function($){ var page = 1; $('#load-more').on('click', function(){ page++; $.ajax({ url: ajaxloadmore.ajaxurl, type: 'post', data: { action: 'load_more', page: page }, success: function(response){ $('#post-container').append(response); } }); }); });

 Method 2: Infinite Scroll – Load on Scroll with AJAX

Want to automatically load posts as users scroll? Here’s how.

Step 1: Use Intersection Observer or Scroll Event

Add this JavaScript instead of the button click method:

javascript

jQuery(function($){ var page = 1; var loading = false; function loadMore() { if (loading) return; loading = true; page++; $.ajax({ url: ajaxloadmore.ajaxurl, type: 'post', data: { action: 'load_more', page: page }, success: function(response){ $('#post-container').append(response); loading = false; } }); } $(window).scroll(function(){ if($(window).scrollTop() + $(window).height() >= $(document).height() - 100) { loadMore(); } }); });

???? Tip: Use IntersectionObserver instead for better performance and efficiency on mobile.

 Best Practices for Load More Posts with AJAX

1. Add Loading Spinner: Let users know data is loading.

2. Accessibility: Ensure keyboard and screen reader support.

3. Progressive Enhancement: Fallback to pagination if JavaScript is disabled.

4. Use Lazy Loading for Images for better speed.

5. Use wp_nonce_field() for security in real-world apps.

 SEO Tips for AJAX Load More

• Ensure Google can index loaded content (server-side rendering helps).

• Use pushState() to update URLs when scrolling or loading more.

• Use lazy loading on images and alt attributes for SEO.
