Add products sorting option by star rating ASC in Woocommerce

I'm looking for a way to sort the products by star rating (asc and desc). It seems that i would need to create a custom code for this since something like this for example isn't implemented in Woocommerce.

$options['rating-asc'] is a the piece of code that doesn't work/exist but i use it to express the function i'm looking for like $options['title-desc'].

add_filter( 'woocommerce_catalog_orderby', 'rory_add_custom_sorting_options' );

function rory_add_custom_sorting_options( $options ){
    $options['rating-asc'] = 'Rating (Asc)';
    return $options;
 
}

First you need to define 'rating-asc' sorting options arguments in a custom function hooked in woocommerce_get_catalog_ordering_args hook.

As sorting option "Sort by average rating" exists, if you look to default existing arguments for sorting products by "rating" key, you have that array:

$args = array(
    'orderby' => array(
        'meta_value_num' => 'DESC',
         'ID' => 'ASC'
    ),
    'order' => 'ASC',
    'meta_key' => '_wc_average_rating'
);

So you just need to change 'meta_value_num' => 'DESC' to 'meta_value_num' => 'ASC', then your right working code is going to be like:

add_filter( 'woocommerce_get_catalog_ordering_args', 'enable_catalog_ordering_by_ratings' );
function enable_catalog_ordering_by_ratings( $args ) {
    if ( isset( $_GET['orderby'] ) && 'rating-asc' === $_GET['orderby']
    && isset($args['orderby']['meta_value_num']) ) {
       $args['orderby']['meta_value_num'] = 'ASC';
    }
    return $args;
}

Now you can insert your new sorting option just after "Sort by average rating" existing one like:

add_filter( 'woocommerce_catalog_orderby', 'catalog_orderby_ratings_asc_filter' );
function catalog_orderby_ratings_asc_filter( $options ){
    $sorted_options =[];

    foreach( $options as $key => $label ){
        if( 'rating' === $key ) {
            $sorted_options['rating'] = $options['rating'] . ' ' . __('(Desc)', 'woocommerce');
            $sorted_options['rating-asc'] = $options['rating'] . ' ' . __('(Asc)', 'woocommerce');
        } else {
            $sorted_options[$key] = $label;
        }
    }

    return $sorted_options;
}

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

Your code should work only for adding the sorting option to the dropdown, but if you want it to have effect you need to link it to a meta key or something by adding the correct arguments to the catalog products query like this:

add_filter( 'woocommerce_get_catalog_ordering_args', 'rory_custom_sorting_args' );
 
function rory_custom_sorting_args( $args ) {
 
    if( isset( $_GET['orderby'] ) && 'rating-asc' === $_GET['orderby'] ) {
        $args['meta_key'] = 'rating-asc'; // Replace this with the meta key you want to use for ordering products
        $args['orderby'] = array( 'meta_value' => 'ASC' );
    }
 
    return $args;
 }
