要使此功能正常运行，您只需要一个小功能即可对所有订单进行处理"扫描.状态在初始"钩子上显示，并将此状态更新为已完成".

To get this working you just need a little function that will scan all orders with a "processing" status on the 'init' hook, and that will update this status to "completed".

这是代码:

function auto_update_orders_status_from_processing_to_completed(){
    // Get all current "processing" customer orders
    $processing_orders = wc_get_orders( $args = array(
        'numberposts' => -1,
        'post_status' => 'wc-processing',
    ) );
    if(!empty($processing_orders))
        foreach($processing_orders as $order)
            $order->update_status( 'completed' );
}
add_action( 'init', 'auto_update_orders_status_from_processing_to_completed' );

此代码已经过测试并且可以正常工作.

This code is tested and works.
