我对电子邮件模板中的循环有疑问。我当前的电子邮件库传递了一组数据和一个模板（.html）来搜索和替换。如果我只需要替换方括号[variable]中包含的任何元素，这可以正常工作。然而，我的库无法处理数据数组（循环），我需要一个比下面丑陋方法更优雅的解决方案
干杯。
电子邮件库

self::$mailer->IsHTML(true);
self::$mailer->Subject = $subject;

self::$mailer->From = self::$CI->config->item('email_primary');
try{
if(self::$mailer->Send()){
return true;

}
}
return false;
}
非定义模板的丑陋方法
注意：抱歉这里形成不良......
我不必使用预先制作的模板，而是必须动态传递模板，以便运行带有数据的foreach循环

编辑：感谢Landons，
if ($order->update_attributes($update_order)) {
$output = $this->load->view('orders/email', array(
'data' => $somedata
), true);
if (Mailer::sendIt($output, '', $user->email, 'Purchase Confirmation: #' . $order->order_sku . '', false)) {
return true;
}
}
答案 0 :(得分：1)
您是否考虑过将数据传递给视图（并返回内容，而不是显示内容）？
