在订单视图列WooCommerce中显示自定义字段值

要在自定义列中显示此自定义订单商品元数据，请使用以下内容：

    
      // Display data to custom column in admin orders list
add_action( ‘manage_shop_order_posts_custom_column’ , ‘display_enclosed_invoice_order_column_data’ );
function display_enclosed_invoice_order_column_data( $column ) {
    global $the_order, $post;
if( $column  == 'cost_center' ) {
    $values = []; // Initializing
    // Loop through order items
    foreach ( $the_order->get_items() as $item ) {
        if( $cost_centre = $item->get_meta( 'Cost Center' ) ) {
            $values[] = $cost_centre;
        }
    }
    // Display the value(s)
    if( sizeof( $values ) > 0 ) {
        echo implode( ', ', $values); // Convert the array to a coma separated string
    }
}
}
