用php发送电子邮件？

我对PHP非常陌生，正在用PHP尝试一个在线订购网站。我在尝试使用“抄送”发送确认电子邮件时遇到问题

每次处理订单时，订单总是发送到指定的“抄送”地址，但不发送到“收件人”。很可能是由于我的代码中的错误

在收到的电子邮件确认中，它仅显示“发件人”部分，“收件人”部分为空，如下所示：

From: Business@business.co.uk
To: *This space is empty*
CC: orders@business.co.uk

有人能帮我指出哪里出了问题吗？我已经附上下面的代码

//Code to retreive customer email
 $query  = "SELECT od_email 
 FROM tbl_order";
  $result = mysql_query($query) or die(mysql_error());
    $data = mysql_fetch_assoc($result); 

//THIS IS THE EMAIL SENT TO THE CUSTOMER and the restaurant
//define the receiver of the email
$_SESSION['od_email'] = $data['od_email'];
$sendto = $_SESSION['od_email'];
//define the subject of the email
$subject = 'Order Confirmation | Ref No for Order: '.  $_SESSION['orderId']; //this session function works properly
//define the message to be sent. Each line should be separated with \n
$message = 'test';
//Who the message is from
$from = "business@business.co.uk";
$cc = "orders@business.co.uk";
//define the headers we want passed. Note that they are separated with \r\n
$headers  = 'MIME-Version: 1.0' . "\r\n";
$headers .= 'Content-type: text/html; charset=iso-8859-1' . "\r\n";
$headers .= "From:" . $from . "\r\n";
//bcc header going to the restaurant
$headers .= "cc:" . $cc . "\r\n";
//send the email
$mail_sent = @mail( $sendto, $subject, $message, $headers );




unset($_SESSION['od_email']);

我需要它显示的是：

From: **business@business.co.uk**
To: **$_SESSION['od_email'];**
CC: **orders@business.co.uk**

提前感谢您提供的任何帮助

看来问题已经在评论中得到了回答，但全文如下：

未填充

$\u会话['od\u email']

变量，因此收件人地址为空

解决方案是添加查询以从最近的订单中获取用户名：

$sql = "SELECT od_email FROM tbl_order BY od_id DESC LIMIT 1"; 
$result = mysql_query($sql) or mysql_error(); 

//define the receiver of the email 
$row = mysql_fetch_row($result); 
$to = $row[0]

您正在使用会话。在使用之前，您还没有启动任何会话

开始会话。将此添加到页面顶部

session_start();

您确定$\u会话['od\u email']有值吗？如果您
var\u dump（$\u SESSION['od\u email']）
，您会得到什么？完成此操作时也会发生同样的情况。我相信它确实有价值。此字段数据库中的每个部分都有一个有效的测试电子邮件地址。但是，我希望它在客户下订单后选择订单的电子邮件地址。这就是我假设我使用会话功能的原因。我仍然不确定为什么要设置$会话['od\u email']，然后在结束时取消设置。不过，这里最可能的问题似乎是$sendto（和$_SESSION['od_email']）为NULL或空白<代码>退出（$sendto）mail（）之前的code>应该打印它的值。此外，您的查询看起来应该是这样的：“从tbl_order中选择od_电子邮件，其中id=$\u会话['orderId']”，这样您就不会选择每一行。您将如何设置$\u会话['od_电子邮件']”？因为我刚刚意识到它没有设定。基本上，我需要检索会话中的最后一个订单。这就是我设置$会话['od\u email']的原因。有没有更简单的方法从数据库获取这些信息？您需要从MySQL结果中获取数据：$row=MySQL\u fetch\u row（$result）$to=$row[0]；
