I have a question regarding loops within an email template. My current email library gets passed an array of data and a template(.html) to search and replace. This works fine if I just need to replace any element wrapped in a square bracket [variable] . My library however can not deal with arrays of data(looping) and I need a more elegant solution than the ugly approach below
Cheers.
Email Library

self::$mailer = new PHPMailer();
self::$CI =& get_instance();
self::$CI->load->helper('file');

$callback = function ($matches) use ($data){
return ( isset($data[$matches[1]]) )
? $data[$matches[1]]

};
return preg_replace_callback(

$callback,
read_file(EMAIL_TEMPLATES . $template));
}

self::$mailer->SMTPSecure = "ssl";
self::$mailer->Host= self::$CI->config->item('email_host');

}
if($prep)

else

self::$mailer->Body = $data;

self::$mailer->IsHTML(true);
self::$mailer->Subject = $subject;
self::$mailer->AddAddress($to);
self::$mailer->FromName = self::$CI->config->item('email_from');
self::$mailer->From = self::$CI->config->item('email_primary');
try{
if(self::$mailer->Send()){
return true;

throw new phpmailerException(self::$mailer->ErrorInfo);

}
}
return false;
}
Ugly Approach for non-defined templates
Note: sorry about poor formating here…
Instead of using a pre-made template, I have to pass a template on the fly so I can run a foreach loop with the data

Edit: Answer Thanks to 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;
}
}
Have you considered simply passing data to a view (and returning the content, rather than displaying it)?
