Woocommerce related product from primary category

Hello,

Please use the code given below in your theme’s functions.php file to display related products from the primary category:

function rank_math_get_primary_term_id( $taxonomy = 'category', $post = null ) { 
            $post = get_post( $post ); 
         
            $primary_term = get_post_meta(get_queried_object_id(), 'rank_math_primary_product_cat', true);
            return $primary_term;
        } 	
add_filter( 'woocommerce_get_related_product_cat_terms', function( $terms, $product_id ) {
    if ( function_exists( 'rank_math_get_primary_term_id' ) ) {
        $primary_term_product_id = rank_math_get_primary_term_id( 'product_cat', $product_id );
        if ( $primary_term_product_id ) {
            return array( $primary_term_product_id );
        }
    }
    return $terms;
}, 10, 2 );

Hope this helps. Let us know if you need any other assistance.

Thanks.

Hello,

I have checked the filter and it worked fine on my end. Let us know how that goes.

Thanks.

Hello,

We have enabled the option to remove out of stock products and they should no longer be added to the related products list:

We tested a couple of dresses and didn’t see any out-of-stock products.

Hope this helps solve your issues.

Don’t hesitate to get in touch if you have any other questions.
