要使此工作正常运行，您只需要一个小功能即可扫描所有带有处理"命令的订单.'init' 钩子上的状态，并且会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".

代码如下:

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' );

此代码已经过测试且有效.

This code is tested and works.

代码位于活动子主题(或主题)的 function.php 文件中.或者也可以在任何插件 php 文件中.
