如何将PHP邮件（）链接添加到自动“订阅过期”电子邮件的正文中？

Question

我需要在用户订阅完成时发送的电子邮件正文中添加链接。这个链接应该发送一封邮件到一个地址，该地址声明'用户名'想要续订他们的订阅。所以我需要做一个PHP邮件（）内的PHP邮件（），如果你了解我！此外，他们点击链接后，他们应该得到一个谢谢你的消息。下面是当前'sendExpiryEmail'函数的php代码。希望你能帮助！谢谢。

公共函数sendExpiryEmail（$电子邮件）{

foreach($emails as $email){ 

     $name = $email['name']; 

     $emailaddress = $email['email']; 

     $expirydate = date('jS F Y',strtotime($email['datetime_expire'])); 



     $subject = "AZ China Report expiry reminder"; 



     $body = '<p><img src="http://az-china.com/images/azchina_logo_email.jpg"></p>

     // multiple recipients 

     $to = $emailaddress; 

     //$to = 'c23gooey@gmail.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 .= 'From: AZ China <tom.martin@az-china.com>' . "\r\n"; 



     // Mail it 

     mail($to, $subject, $body, $headers); 

    }

来处理这一点的方法是设置一个查找或结合表，那里存储您每更新请求生成与相应的氨基酸唯一识别ID用户名。

该表可能看起来像：

renewals 
------------------------------- 
renewid    | userid 
------------------------------- 
[output of uniqid()] | bob 
[output of uniqid()] | bill 
[output of uniqid()] | sarah 
... 

当你运行你的脚本来收集账户即将到期清单，AA位添加到电子邮件的步骤是：

while ... 

    $renewid = uniqid(); 

    $renewurl = "http://.../renew.php?req=$renewid"; 

    // Put that URL in the body of the email. 

    $renewsql = " 
INSERT INTO renewals (
    renewid, userid 
) VALUES (
    '$renewid', '{$email['userid']}' 
) 
"; 

    if ($db->query($renewsql)) { 
     mail(...); 
    } 
} 

假设$email['userid']是用户ID字段被调用的任何内容，并且您在查询$emails中选择了它。

然后，像http://.../renew.php?req=$renewid一个网址，你可能会做renew.php是这样的：

<?php 

$renew = preg_replace('/^a-z0-9/i', '', $_GET['req']); 

if ($renew != '') { 
    $which = $db->query(" 
SELECT userid 
FROM renewals 
WHERE renewid = '$renew' 
LIMIT 1 
"); 

    if ($which->hasRows()) { 
     $userid = $which->get(0)->field('userid'); 

     // do whatever renewal stuff with the $userid 

     $db->query("DELETE FROM renewals WHERE renewid = '$renewid'"); 
    } 
} 

你可以做的是增加一个expires列，这样就可以定期清理旧续订请求另一件事。但或多或少，这是总体思路。
