CakePHP Mailgun带有附件的电子邮件

Question

I have an app built with CakePHP 2.9 and am trying to send emails using mailgun. The emails get delivered with all of the needed content however attachments dont show up. Mailgun log looks good except for the attachment array being empty.

I was trying to send a dynamic file (pdf) however for testing purposes I've switched to a local png file and it still isn't working

I've been trying a few ways to get the attachment to be added but havent been able to here is the code

Email code

$Email = new CakeEmail('mailgun');
$Email->template('pdf');
$Email->emailFormat('html');
$Email->to($email);
$Email->subject($configdata['Config']['accountstatementsubject']);
$Path = WWW_ROOT."pdf/";
$fileName = 'Account_'.$usersGenrate['User']['fname'].'.pdf';

$Email->attachments(WWW_ROOT.'img/bg.png');
$Email->viewVars(array('emailcontent' => $configdata['Config']['accountstatementcontent'],
                        'user' => $usersGenrate['User']));
$Email->send();

Here is the CurlTransport.php

            array(
                'text' => $email->message(CakeEmail::MESSAGE_TEXT),
                'html' => $email->message(CakeEmail::MESSAGE_HTML)
            )
        );
        foreach ($post_preprocess as $k => $v) {
            if (! empty($v)) {
                $post[strtolower($k)] = $v;
            }
        }

        if ($attachments = $email->attachments()) {
            $i = 1;
            foreach ($attachments as $attachment) {
                $post['attachment[' . $i . ']'] = "@" . $attachment["file"];
                $i++;
            }
        }
        $ch = curl_init('https://api.mailgun.net/v2/' . $this->_config['mailgun_domain'] . '/messages');
        curl_setopt($ch, CURLOPT_POST, true);

        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);

        curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_BASIC);
        curl_setopt($ch, CURLOPT_POSTFIELDS, $post);
        $response = curl_exec($ch);
        if ($response === false) {
            throw new SocketException("Curl had an error.  Message: " . curl_error($ch), 500);
        }
        $http_status = curl_getinfo($ch, CURLINFO_HTTP_CODE);
        if ($http_status != 200) {
            throw new SocketException("Mailgun request failed.  Status: $http_status, Response: $response", 500);
        }
        curl_close($ch);
        return array(
            'headers' => $this->_headersToString($email->getHeaders(), PHP_EOL),
            'message' => implode(PHP_EOL, $email->message())
        );
    }
}

Answer 1

Here is the updated code to work with attachments

Basically changed the line From

$post['attachment[' . $i . ']'] = "@" . $attachment["file"];

To

$post['attachment[' . $i . ']'] = curl_file_create($attachment["file"]);
