按元字段订购 WooCommerce 产品

Question

我的每个产品都有一个特殊的元字段（时间戳）。我想按此时间戳在所有页面上订购我的产品。

这是我的函数文件中当前的代码。产品不重新订购。

add_action( 'woocommerce_product_query', 'mind_woocommerce_catalog_orderby' );
function mind_woocommerce_catalog_orderby( $query ) {
    if(!is_admin() && $query->is_main_query() ) {
        $query->set( 'meta_key','_start_date' );
        $query->set( 'orderby','meta_value' );
        $query->set( 'order','DESC' );
    }
}

我已经确认每个帖子都有一个“_start_date”元字段。

是否有我应该注意的 woocommerce 设置？

试一试。

function custom_add_postmeta_ordering_args( $sort_args ) {

    $orderby_value = isset( $_GET['orderby'] ) ? wc_clean( $_GET['orderby'] ) : apply_filters( 'woocommerce_default_catalog_orderby', get_option( 'woocommerce_default_catalog_orderby' ) );
    switch( $orderby_value ) {

        // Name your sortby key whatever you'd like; must correspond to the $sortby in the next function
        case '_start_date':
            $sort_args['orderby']  = 'meta_value';
            // Sort by meta_value because we're using alphabetic sorting
            $sort_args['order']    = 'desc';
            $sort_args['meta_key'] = '_start_date';
            // use the meta key you've set for your custom field, i.e., something like "location" or "_wholesale_price"
            break;

    }

    return $sort_args;
}
add_filter( 'woocommerce_get_catalog_ordering_args', 'custom_add_postmeta_ordering_args' );
// Add these new sorting arguments to the sortby options on the frontend
function custom_add_new_postmeta_orderby( $sortby ) {

    // Adjust the text as desired
    $sortby['_start_date'] = __( 'Sort by start date', 'woocommerce' );

    return $sortby;
}
add_filter( 'woocommerce_default_catalog_orderby_options', 'custom_add_new_postmeta_orderby' );
add_filter( 'woocommerce_catalog_orderby', 'custom_add_new_postmeta_orderby' );
