We will take a look at two ways of creating an AJAX category filter for WooCommerce for your store. In case you don’t know, AJAX means that our filters will work fully without a page refresh:

• First, we will create product category filters for a WooCommerce block theme, using the WordPress Interactivity API.
• Second, if your store has been out there for many years, there is a big chance that you’re using a classic WordPress theme (for example, the Storefront theme), and I will take a look at that case as well.

Let’s dive into it.

In this guide, I will dive deep into the process of creating an AJAX category filter for a WordPress website. We will do it both with the help of plugins and without plugins at all.

In this tutorial, I will show you two examples of how to use Select2 when creating custom fields in WordPress admin. Particularly, I will show you how to do it in meta boxes in the classic editor, but you can do the same for taxonomy settings or options pages.

In the first example, we will use Select2 to create a multiselect dropdown with tags. In the second one, it will become more interesting; we will do the same for posts, but also with an AJAX search (both examples will also be implemented in two ways – programmatically and with my Simple Fields plugin).

In this tutorial, I will uncover two ways how you can load more products with AJAX on your WooCommerce store’s pages.

1. Firstly, I will show you can do it in classic WooCommerce themes, for example, Storefront.
2. Then, we will do it for a block theme.

As a bonus, we will take a look at how to create an infinite scroll for WooCommerce products.

In this tutorial, I am going to show you how you can implement asynchronous post loading in WordPress or even an infinite scroll.

Please consider that there could be two different implementations for the AJAX load more button and it depends on the theme you’re using today. For example:

• If you’re using old-fashioned themes, then you can create a load more button with a little bit of PHP and JavaScript code (and that’s exactly what we’re going to do in this tutorial).
• If you’re using block themes (FSE themes), then the whole implementation comes down to a custom block which will represent our load more button. I am going to talk about it as well.

No matter which way you choose, upgrading your AJAX load more button into an infinite scroll is not a big deal, by the way.

In this tutorial, we will discuss different ways of how you can create paginated comments in WordPress, in every of the mentioned ways we’re going to use AJAX (it means, that the comments pagination, load more button, or infinite scroll will work without page refresh).
