如何向所有Wordpress用戶發送電子郵件

Question

我正在嘗試向所有用戶發送有關自定義事件的電子郵件。 為此，我編寫了以下代碼，但無法正常工作。 我究竟做錯了什么？

//send mail to all users

$result= $wpdb->get_var( $wpdb->prepare("SELECT user_email FROM $table_users"));

foreach($result as $email) {

      $headers = "MIME-Version: 1.0" . "\r\n";
      $headers .= "Content-type:text/html;charset=UTF-8" . "\r\n";
      $headers.= "From:mysite<info@mysite.com>\r\n";
      $message = "<b>Dear! user</b>,<br/><br/> A new share is available to purchase 
                        for amount $".$sellamt."<br>this is an automated mail.pls  don't reply to this mail. ";
      $send=mail($email,"mysite:New share Available to Purchase!",$message,$headers);
}

header('Location: /offer_csuccess');  
exit();

Answer 1

使用get_users函數可根據角色或您傳遞的任何參數獲取所有用戶。

$users = get_users();

foreach( $users as $user ) {

    wp_mail( $user->user_email, "New Share Available to Purchase!", $message );
}

此外，使用WordPress的好處是不必每次都提及標題。 您只需要使用wp_mail即可 。 實際上，發送電子郵件確實更加簡單。

希望對您有所幫助:)

Answer 2

獲取所有用戶函數get_users();

$all_users = get_users();
foreach ($all_users as $user) {


      $headers = "MIME-Version: 1.0" . "\r\n";
      $headers .= "Content-type:text/html;charset=UTF-8" . "\r\n";
      $headers.= "From:mysite<info@mysite.com>\r\n";
      $message = "<b>Dear! user</b>,<br/><br/> A new share is available to purchase 
                        for amount $".$sellamt."<br>this is an automated mail.pls  don't reply to this mail. ";
      $send=mail($user->user_email,"mysite:New share Available to Purchase!",$message,$headers);
}

 exit();
