Question

我有两个数据库表用户＆amp; user_players我试图让它与之合作。

users
CREATE TABLE `users` (
 `id` int(11) NOT NULL AUTO_INCREMENT,
 `firstname` varchar(100) COLLATE utf8_unicode_ci NOT NULL,
 `lastname` varchar(100) COLLATE utf8_unicode_ci NOT NULL,
 `email` varchar(100) COLLATE utf8_unicode_ci NOT NULL,
 `phone_number` varchar(15) COLLATE utf8_unicode_ci NOT NULL,
 `username` varchar(100) COLLATE utf8_unicode_ci NOT NULL,
 `password` varchar(100) COLLATE utf8_unicode_ci NOT NULL,
 `salt` varchar(32) COLLATE utf8_unicode_ci NOT NULL,
 `joined` datetime NOT NULL,
 `group` int(11) NOT NULL,
 PRIMARY KEY (`id`)
) ENGINE=MyISAM AUTO_INCREMENT=58 DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci

这不是所有的user_players，而是讨论所需的全部内容。

user_players
CREATE TABLE `user_players` (
 `id` int(11) NOT NULL AUTO_INCREMENT,
 `user_id` int(11) NOT NULL,
 `firstname` varchar(100) COLLATE utf8_unicode_ci NOT NULL,
 `lastname` varchar(100) COLLATE utf8_unicode_ci NOT NULL,
 `username` varchar(100) COLLATE utf8_unicode_ci NOT NULL,
 `email` varchar(100) COLLATE utf8_unicode_ci NOT NULL,

我想向具有2,3,4和5组的用户发送php电子邮件。然后，我希望在user_players表中包含用户的名称。（我在页面中执行随机播放并将随机播放的结果插入到user_players中以获取随机顺序）。然后，我想在我的电子邮件中的user_players表中列出用户订单。即：

鲍勃
苏西
吉姆

等

$con = mysqli_connect("localhost", "root", "", "db");
$stmt = $con->prepare("SELECT * FROM users, user_players WHERE users.`group`=2, 3, 4, 5");

    $order_row = mysqli_fetch_assoc($stmt);

    $order_id = $_POST['id'];
    $order_firstname = $order_row['firstname'];
    $order_lastname = $order_row['lastname'];
    $order_username = $order_row['username'];
    $order_email = $order_row['email'];
    $order_group = $order_row['group'];

    $to = $order_email;
    $subject = ' Draft Order';
    $message .= '
    <html>
    <head>
        <title>Draft Order</title>
    </head>
    <body>
        <p>Hi '.$order_firstname.',</p><br>
        <p>The Sunday Funday draft order has been created. This is a completely randomized selection.</p>
        <p>The draft order is of the following:</p><br>';
        foreach($order_row as $order) {
            echo $order_firstname;
        }
        $message .='<p>Thank you,</p>
        <p>Administration</p>
    </body>
    </html>
    ';

    $from = "user-requests@example.com";
    $Bcc = "user-requests-confirm@example.com";

    // To send HTML mail, the Content-type header must be set
    $headers  = 'MIME-Version: 1.0' . "\r\n";
    $headers .= 'Content-type: text/html; charset=iso-8859-1' . "\r\n";

    // Additional headers
    $headers .= 'To: ' .$to. "\r\n";
    $headers .= 'From: ' .$from. "\r\n";
    $headers .= 'Bcc: '.$Bcc. "\r\n";

    // Send the email
    mail($to,$subject,$message,$headers);
}

我收到了电子邮件的关注错误..

Warning: mysqli_fetch_assoc() expects parameter 1 to be mysqli_result, boolean given in /home4/pfarley1/public_html/example.com/userCreator.php on line 248

Notice: Undefined variable: message in /home4/pfarley1/public_html/example.com/userCreator.php on line 267

Warning: Invalid argument supplied for foreach()

有谁知道如何才能使这项工作？
