Question

我正在尝试为网络表单设置电子邮件通知：

$query = "UPDATE email_tbl SET notified='".mysqli_real_escape_string($conn,$notified)."', reasoning='".mysqli_real_escape_string($conn,$reasoning)."' WHERE id='$id'";

$result=mysqli_query($conn, $query);

$query2 = "SELECT `or_user` FROM `usf_tbl` WHERE `id` = $id";

$result = mysqli_query($conn,$query2);

while ($row= mysqli_fetch_assoc($result))

$to = "example@email.com, $row[or_user]";
$subject = "Email Notification";
$message = "

<html>
<p>Email Notification for $row[or_user]</p>
</html>";

我正在接收所需的电子邮件，但该电子邮件不包含“or_user”。但是，电子邮件会根据需要发送到“or_user”。为什么不在实际的电子邮件中打印“or_user”？提前谢谢。

Answer 1

$query = "UPDATE email_tbl SET notified='".mysqli_real_escape_string($conn,$notified)."', reasoning='".mysqli_real_escape_string($conn,$reasoning)."' WHERE id='$id'";

$result=mysqli_query($conn, $query);

$query2 = "SELECT `or_user` FROM `usf_tbl` WHERE `id` = $id";

$result = mysqli_query($conn,$query2);

while ($row= mysqli_fetch_array($result))
{
     $to = "example@email.com, $row['or_user']";
     $subject = "Email Notification";
     $message = "

       <html>
            <p>Email Notification for". $row['or_user']."</p>
       </html>";
}

Answer 2

使用mysqli_num_rows检查天气查询返回结果

$query2 = "SELECT `or_user` FROM `usf_tbl` WHERE `id` = $id";
$result = mysqli_query($conn, $query2);
$email = "";
$row_cnt = mysqli_num_rows($result);
if ($row_cnt > 0) {
    $row = mysqli_fetch_assoc($result);

//在不使用while循环的情况下获取数据

    $email = $row['or_user'];
    $to = "example@email.com, $email";// pass $email here
    $subject = "Email Notification";

//使用sprintf将电子邮件作为

传递给消息

$message = sprintf("<html>
<p>Email Notification for %s</p>
</html>", $email);
}//end if condition here

PHP - 无法回显$ row
