How Do I Add a Custom Filter in WooCommerce?

Adding a custom filter in WooCommerce is a great way to add extra functionality to your online store. By adding a custom filter, you can easily change the way products are displayed on your store, or even add new features to your shop. In this article, we will show you how to add a custom filter in WooCommerce.

Before we begin, you need to have a basic understanding of how WooCommerce works. If you don’t know how WooCommerce works, we recommend that you check out our WooCommerce 101 course. Once you’re familiar with the basics of WooCommerce, you can come back to this article and follow the instructions below.

Adding a custom filter in WooCommerce is easy. All you need to do is add a new function to your child theme’s functions.php file. In this function, you will need to use the add_filter() function. This function allows you to modify an existing WooCommerce filter. For example, if you want to change the way products are displayed on your store, you can use this function to modify the woocommerce_product_loop() filter.

In the example below, we will show you how to add a custom filter that will change the number of products displayed on your store’s homepage. To do this, we will use the pre_option_posts_per_page filter. This filter allows us to change the number of posts that are displayed on our site before the options are saved in the database.

Example:

function my_custom_filter( $posts_per_page ) {
    return 10; //Change this number to whatever you want
}
add_filter( 'pre_option_posts_per_page', 'my_custom_filter' );

• You can learn more about the add_filter() function by reading the WordPress codex.
