在子主题函数中执行以下代码。php文件，如下所示。

function wc_remove_cancelled_status( $statuses ){
  if( isset( $statuses[\'wc-cancelled\'] ) ){
      unset( $statuses[\'wc-cancelled\'] );
  }
  return $statuses;
} 
add_filter( \'wc_order_statuses\', \'wc_remove_cancelled_status\' );

我认为用户可以在五分钟内更改订单状态。所以我用hook编写了下面的代码-

add_action( \'woocommerce_order_status_failed\', \'the_dramatist_woocommerce_auto_delete_order\' );
add_action( \'woocommerce_order_status_pending\', \'the_dramatist_woocommerce_auto_delete_order\' );
add_action( \'woocommerce_order_status_cancelled\', \'the_dramatist_woocommerce_auto_delete_order\' );

function the_dramatist_woocommerce_auto_delete_order( $order_id ) {
    // 5*60 = 300 seconds. Here 1minute = 60 seconds.
    wp_schedule_single_event(tim() + 300, \'the_dramatist_main_delete_event\', $order_id);
}

function the_dramatist_main_delete_event( $order_id ) {
    global $woocommerce;
    $order = new WC_Order( $order_id );
    $order_status = $order->get_status();
    if ( !$order_id )
        return false;
    if (\'cancelled\' == $order_status || \'failed\' == $order_status ||   \'pending\' == $order_status ) {
        wp_delete_post($order_id,true);
        return true;
    }
    return false;
}

P、 我想是美国sleep() 函数将导致WordPress生命周期延迟。所以我们最好使用wp_schedule_single_event 作用所以我更新了我的代码。
