I’m trying to do a woocommerce query that results in all products that have the custom attribute Height that are in a specific range.

function testing_woo_product_query($q)
{
    $min_height = 1;
    $max_height = 5;
    //Product custom attribute Height, get all products between min_height and max_height
    $q->set("tax_query", array(
        "relation" => 'AND',
        array(
            "taxonomy" => "Height",
            "field" => "slug",
            "terms" => array($min_height),
            "operator" => ">="
        ),
        array(
            "taxonomy" => "Height",
            "field" => "slug",
            "terms" => array($max_height),
            "operator" => "<="
        )
    ));
}

add_action("woocommerce_product_query", "testing_woo_product_query");
