php - 使用 Woo Cancel for Customers Plugin 在我的帐户订单列表中添加取消按钮

Question

在我的 WooCommerce 网站中，我正在使用此插件 WooCommerce Order Cancel for Customers允许客户根据付款类型和时间延迟取消订单。但是取消按钮只出现在“woocommerce_order_details_after_order_table”上。

我希望此取消按钮出现在“查看”按钮附近的“我的帐户”>“订单列表”中:


我试图编辑插件并添加以下代码:add_filter('woocommerce_my_account_my_orders_actions', array($this, 'order_cancel_button'), 10, 2);
但它不起作用:查看按钮不见了，取消按钮也没有显示。

这是整个代码:

如何让“取消”按钮出现在我的账户 > 订单列表中的操作栏中？

Answer 1

New Update May 2018: Conditional Cancel Button on my account orders list in Woocommerce

Old Update regarding your comment: The cancel button is available 3 days (from creation date) and solved a bug issue when the cancel button is pressed (made on January 2018)

无需编辑或使用此插件，您可以在操作栏中的“我的帐户”>“订单列表”中启用取消按钮，使用您将设置的一小段代码:

订单状态:您希望“取消”按钮出现的位置

从订单创建日期开始的持续时间(以天为单位)。

这是代码:

add_filter( 'woocommerce_valid_order_statuses_for_cancel', 'custom_valid_order_statuses_for_cancel', 10, 2 );
function custom_valid_order_statuses_for_cancel( $statuses, $order ){

    // Set HERE the order statuses where you want the cancel button to appear
    $custom_statuses    = array( 'completed', 'pending', 'processing', 'on-hold', 'failed' );

    // Set HERE the delay (in days)
    $duration = 3; // 3 days

    // UPDATE: Get the order ID and the WC_Order object
    if( isset($_GET['order_id']))
        $order = wc_get_order( absint( $_GET['order_id'] ) );

    $delay = $duration*24*60*60; // (duration in seconds)
    $date_created_time  = strtotime($order->get_date_created()); // Creation date time stamp
    $date_modified_time = strtotime($order->get_date_modified()); // Modified date time stamp
    $now = strtotime("now"); // Now  time stamp

    // Using Creation date time stamp
    if ( ( $date_created_time + $delay ) >= $now ) return $custom_statuses;
    else return $statuses;
}

代码位于事件子主题(或主题)的 function.php 文件或任何插件文件中。
此代码已在 Woocommerce 3+ 上进行测试并有效。你会得到类似的东西:

注:此函数返回的默认订单状态为 'pending'和 'failed'

You can also use the WC_Order object argument in the function to set some custom conditions.
