今天在猪八戒上，看到有人发布任务，要求二次开发最土团购系统，用户下单支付成功后，需要发送通知邮件，闲的没事，简单看了一下，感觉很好实现。在这里把基本思路说一下。
首先，编写邮件内容函数和模板。这个可以参考订阅邮件的发送，在/include/fuction/mailer.php这个文件里，照猫画虎，添加一个处理改邮件的函数。
function mail_order($city, $team, $partner, $order,$user){}
然后再新建一个模板，mail_order.html，具体表现形式，通过css控制即可。
函数和模板搞定，只需要调用函数，就可以将邮件发送出去了。
每一订单付款后，系统都会调用统一的一个方法，static public function BuyOne($order)，这个方法在ZTeam.class这个类里，只需要在这个方法的最后调用mail_order即可在订单付款之后，将邮件发送出去。
补充：有朋友建议我再写详细一点，那我就把代码贴出来好了。
在/include/fuction/mailer.php最后面，添加如下代码
//订单付款后，发送邮件通知
function mail_order($team, $partner, $order)
{
global $INI;
$encoding = $INI['mail']['encoding'] ? $INI['mail']['encoding'] : 'UTF-8';
$week = array('日','一','二','三','四','五','六');
$today = date('Y年n月j日 星期') . $week[date('w')];
$user = Table::Fetch('user',$order['user_id']);//获取用户信息，主要是为了得到Email
/*获取优惠券*/
$condition = array(
'order_id' => $order['id'],
);
$coupons = DB::LimitQuery('coupon', array(
'condition' => $condition,
));
/*end*/
$vars = array(
'today' => $today,
'team' => $team,
'city' => $city,
'order' => $order,
'partner' => $partner,
'coupons'=>$coupons,
'help_email' => $INI['mail']['helpemail'],
'help_mobile' => $INI['mail']['helpphone'],
'notice_email' => $INI['mail']['reply'],
);
$message = render('mail_order', $vars);
$options = array(
'contentType' => 'text/html',
'encoding' => $encoding,
);
$from = $INI['mail']['from'];
$to = $user['email'];
$subject = '您在'.$INI['system']['sitename'].'的订单信息';
if ($INI['mail']['mail']=='mail') {
Mailer::SendMail($from, $to, $subject, $message, $options);
} else {
Mailer::SmtpMail($from, $to, $subject, $message, $options);
}
}
function mail_order($team, $partner, $order)
{
global $INI;
$encoding = $INI['mail']['encoding'] ? $INI['mail']['encoding'] : 'UTF-8';
$week = array('日','一','二','三','四','五','六');
$today = date('Y年n月j日 星期') . $week[date('w')];
$user = Table::Fetch('user',$order['user_id']);//获取用户信息，主要是为了得到Email
/*获取优惠券*/
$condition = array(
'order_id' => $order['id'],
);
$coupons = DB::LimitQuery('coupon', array(
'condition' => $condition,
));
/*end*/
$vars = array(
'today' => $today,
'team' => $team,
'city' => $city,
'order' => $order,
'partner' => $partner,
'coupons'=>$coupons,
'help_email' => $INI['mail']['helpemail'],
'help_mobile' => $INI['mail']['helpphone'],
'notice_email' => $INI['mail']['reply'],
);
$message = render('mail_order', $vars);
$options = array(
'contentType' => 'text/html',
'encoding' => $encoding,
);
$from = $INI['mail']['from'];
$to = $user['email'];
$subject = '您在'.$INI['system']['sitename'].'的订单信息';
if ($INI['mail']['mail']=='mail') {
Mailer::SendMail($from, $to, $subject, $message, $options);
} else {
Mailer::SmtpMail($from, $to, $subject, $message, $options);
}
}
然后在include/template/目录下，新建一个模板文件mail_order.html。这个文件里，大家需要自己修改一下css代码，以便显示风格，和自己的网站相匹配。我随便写了一下，比较难看，只是把内容订单内容列出来了。代码比较多，我放到附件里，大家自行下载。

最后，在include/classes/ZTeam.class.php中找到static public function BuyOne这个函数，在ZCredit::Buy($order['user_id'], $order);这行代码后面添加：
$partner = Table::FetchForce(‘partner’, $team['partner_id']);
mail_order($team, $partner, $order) ;
这样，购买之后，就可以自动发送邮件通知了。
其实可以做进一步的升级，比如，用户下单之后，马上发一个通知邮件，付款成功之后，再发一个通知邮件。做一些设置，某个项目是否自动发送邮件，等等。
