Php WooCommerce基于元数据的自定义范围目录排序

我想你已经在woocommerce_get_catalog_ordering_args钩子里挂上了你的函数.

我还假设您添加了一个定制的"推荐"排序选项，类似于:

add_filter( 'woocommerce_catalog_orderby', 'add_catalog_orderby_recommended' );
function add_catalog_orderby_recommended( $orderby ) {
    $orderby['recommended'] = __('Sort by recommended', 'woocommerce');
    return $orderby;
}

现在，请注意，$sort_args只处理‘orderby’和‘order’，而不处理‘meta_query’.

然后，您将用以下代码替换现有的挂钩函数:

add_filter( 'woocommerce_get_catalog_ordering_args', 'catalog_ordering_by_recommended', 10, 3 );
function catalog_ordering_by_recommended( $args, $orderby, $order ) {
    if ( isset( $_GET['orderby'] ) && $_GET['orderby'] === 'recommended' ) {
        // Custom sorting order
        $args['orderby'] = array(
            'meta_value_num' => 'ASC', // Sort by diameter ascending
        );
    }
    return $args;
}

add_filter( 'woocommerce_product_query', 'product_query_by_recommended', 10, 1 );
function product_query_by_recommended( $q ) {
    if ( isset($_GET['orderby']) && $_GET['orderby'] === 'recommended' ) {
        // Read cookie values
        $min_diameter = isset( $_COOKIE['Min_Diameter'] ) ? intval( $_COOKIE['Min_Diameter'] ) : 0;
        $max_diameter = isset( $_COOKIE['Max_Diameter'] ) ? intval( $_COOKIE['Max_Diameter'] ) : PHP_FLOAT_MAX;

        $meta_query = $q->get('meta_query');

        $meta_query['relation'] = 'AND';

        $meta_query[] = array(
            'key'     => '_diameter',
            'value'   => array( $min_diameter, $max_diameter ),
            'compare' => 'BETWEEN',
            'type'    => 'NUMERIC',
        );

        $q->set('meta_query', $meta_query);
        $q->set('orderby', array(
            'meta_value_num' => 'ASC', // Sort by diameter ascending
        ) );
    }
}

应该能行得通.
