WooCommerce - 通過「save_post」掛鉤更新訂單時發送通知電子郵件

Question

WooCommerce在創建新訂單時創建新帖子shop_order帖子類型。所以我想用wordpress save_post動作鉤發送訂單通知郵件。

我寫了下面的代碼：

add_action('save_post', 'notify_shop_owner_new_order', 10, 3); 
function notify_shop_owner_new_order($post_ID, $post) { 
    if($post->post_type == 'shop_order') { 
     $headers = 'From: foo <foo@bar.com>'; 

     $to = 'foo@bar.com'; 
     $subject = sprintf('New Order Received'); 
     $message = sprintf ('Hello, musa ! Your have received a new order from .Check it out here :'); 

     wp_mail($to, $subject, $message, $headers); 
    } 
} 

但它不工作。

如果下面我用不用是檢查型工作原理：

add_action('save_post', 'notify_shop_owner_new_order', 10, 3); 
function notify_shop_owner_new_order($post_ID, $post) { 
    $headers = 'From: foo <foo@bar.com>'; 

    $to = 'foo@bar.com'; 
    $subject = sprintf('New Order Received'); 
    $message = sprintf ('Hello, musa ! Your have received a new order from .Check it out here :'); 

    wp_mail($to, $subject, $message, $headers); 
} 

我不明白是什麼問題。我需要使用功能參數$post和$post_id來獲得帖子鏈接。

任何幫助？

感謝

你需要先拿到$ post對象是這樣的：

add_action('save_post', 'notify_shop_owner_new_order', 1, 2); 
function notify_shop_owner_new_order($post_ID){ 

    // Get the post object 
    $post = get_post($post_ID); 

    if($post->post_type == 'shop_order') { 
     $headers = 'From: musa <wordpress@muazhesam.com>'; 

     $to = 'musa.ssmc42@gmail.com'; 
     $subject = sprintf('New Order Received'); 
     $message = sprintf ('Hello, musa ! Your have received a new order from .Check it out here :'); 

     wp_mail($to, $subject, $message, $headers); 
    } 
} 

代碼進行了測試和工程...

代碼放在您的活動子function.php文件主題（或主題）。或者也可以在任何插件php文件中使用。
