Arrange sort WooCommerce products displayed in a specific product category

Question

I have 15 product categories and 50+ products into my WooCommerce website. I want to arrange (sort) products from a specific category with an array of product ids.

This is my code attempt:

add_filter( 'woocommerce_get_catalog_ordering_args', 'my_ordering_function', 10, 2 );
function my_ordering_function( $args ) {

    $product_category = 'engineering-service'; 

    if( ! is_product_category($product_category) ) return $args;

    $args['post__in'] = array( 181, 8622, 8689, 8832 );
    $args['orderby'] = 'post__in';
    $args['order'] = 'ASC';

    return $args;
}

This doesn't work.

Which hooked function do I need to use? How can I do that programmatically?

Answer 1

You are not using the right hook and the right way. Try the following:

add_filter( 'woocommerce_product_query', 'engineering_service_product_query', 10, 2 );
function engineering_service_product_query( $q, $query ) {
    $product_category = array('engineering-service');
    $product_ids      = array( 181, 8622, 8689, 8832 );

    if( is_product_category( $product_category ) ) {
        $q->set('post__in', $product_ids );
        $q->set('orderby', 'post__in');
        $q->set('order', 'ASC');
    }
}

Code goes in functions.php file of your active child theme (or active theme). Tested and works.
