Mailgun send mail with attachment

Question

I am trying to send a mail with attachments with mailgun. The mail itself is fine, but it is missing the attachment. Also in the mailgun log it shows up fine, but the attachment array is empty.

I replaced my credentials with example.com. The file is placed in a subdirectory and is readable.

$filename = 'directory/example.pdf';
$parameters = array('from' => 'Example <example@mail.example.com>',
                    'to' => 'example@example.com',
                    'subject' => 'Subject',
                    'text' => 'This is just a test.',
                    'attachment[1]' => '@' . $filename);

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'https://api.mailgun.net/v3/mail.example.com/messages');
curl_setopt($ch, CURLOPT_USERPWD, 'api:key-ThisIsJustARandomString');

curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: multipart/form-data'));
curl_setopt($ch, CURLOPT_POSTFIELDS, $parameters);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

$response = curl_exec($ch);

I don't get an error, this is the $response:

string(103) "{
    "id": "<20170514122638.8820.55203.4543B111@mail.example.com>",
    "message": "Queued. Thank you."
}"

Within the mailgun logs no attachments are listed:

"message": {
    "headers": {
        "to": "example@example.com",
        "message-id": "20170514122638.8820.55203.4543B111@mail.example.com",
        "from": "Example <example@mail.example.com>",
        "subject": "Subject"
    },
    "attachments": [],
    "size": 349
},

According to all documentation I found this would be the correct solution, but it is not working.

Thanks in advance for all replies.

Answer 1

Change your first code to:

$filename = 'directory/example.pdf';
$parameters = array('from' => 'Example <example@mail.example.com>',
                'to' => 'example@example.com',
                'subject' => 'Subject',
                'text' => 'This is just a test.',
                'attachment[1]' => curl_file_create($filename, 'application/pdf', 'example.pdf'));

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'https://api.mailgun.net/v3/mail.example.com/messages');
curl_setopt($ch, CURLOPT_USERPWD, 'api:key-ThisIsJustARandomString');

curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: multipart/form-data'));
curl_setopt($ch, CURLOPT_POSTFIELDS, $parameters);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

$response = curl_exec($ch);

I changed '@'.$filename to curl_file_create($filename, 'application/pdf', 'example.pdf').

See documentation curl_file_create and check the notes for PHP < 5.5.

Answer 2

or use the api https://documentation.mailgun.com/en/latest/api-sending.html#examples

once the domains and parameters are set you can then just use $result = $mgClient->messages()->send( $domain, $params );

Answer 3

This worked for me.

<?php
 $path = $filename;
 define('MAILGUN_URL', 'https://api.mailgun.net/v3/domainname'); 
 define('MAILGUN_KEY', 'private api key from mail gun');
 **function sendmailbymailgun**($to,$toname,$mailfromname,$mailfrom,$subject,
  $html,$text,$tag,$replyto, $path){

$array_data = array(
'from'=> $mailfromname .'<'.$mailfrom.'>',
'to'=>$toname.'<'.$to.'>',
'subject'=>$subject,
'html'=>$html,
'text'=>$text,
'o:tracking'=>'yes',
'o:tracking-clicks'=>'yes',
'o:tracking-opens'=>'yes',
'o:tag'=>$tag,
'h:Reply-To'=>$replyto,
 'attachment[0]' =>  curl_file_create(__dir__."\\".$path, 'application/pdf', $path),
 'attachment[1]' =>  curl_file_create(__dir__."\\".$path, 'application/pdf', "example.pdf")
);
$session = curl_init(MAILGUN_URL.'/messages');
curl_setopt($session, CURLOPT_HTTPAUTH, CURLAUTH_BASIC);
curl_setopt($session, CURLOPT_USERPWD, 'api:'.MAILGUN_KEY);
curl_setopt($session, CURLOPT_POST, true);
curl_setopt($session, CURLOPT_POSTFIELDS, $array_data);
curl_setopt($session, CURLOPT_HTTPHEADER, array('Content-Type: multipart/form-data'));
curl_setopt($session, CURLOPT_HEADER, false);
curl_setopt($session, CURLOPT_ENCODING, 'UTF-8');
curl_setopt($session, CURLOPT_RETURNTRANSFER, true);
curl_setopt($session, CURLOPT_SSL_VERIFYPEER, false);
$response = curl_exec($session);
curl_close($session);
$results = json_decode($response, true);
return $results;
}

  //: call the function
  $res = sendmailbymailgun("example@yahoo.com","Recipeint Name", "Sender Name", "sender@example.com","Email subject","Email body. find two attachment","","tags", "no-reply@example.com", $path);
  echo "<pre>".print_r($res, true)."</pre>";  


?>

Answer 4

$dest = "filepath/test.pdf";
$result = $mgClient->messages()->send($domain,
            array('from'    => 'Tester <test@test.com>',
              'to'      => 'test@test02.com',
              'subject' => 'Testing',
              'html'    => '<h1>Normal Testing</h1>',
              'attachment' => array(
                array(
                    'filePath' => $dest,
                    'filename' => 'test.pdf'
                    )
                )
              ));

This code is worked properly for me.

Answer 5

This works for me. I have passed the attachment file URL in the attachment array. now I can send multiple attachments in email.

$attachment = [  0 => 
'https://www.crm.truerater.com/public/assets/client_upload_images/1634327873.png',
         1 => 'https://www.crm.truerater.com/public/assets/client_upload_images/1634327873.png'  
];

    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, 'https://api.mailgun.net/v3/truerater.com/messages');
    curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_BASIC);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_POST, 1);
    $post = array(
        'from' =>  $mailfromname .'<'.$mailfrom.'>',
        'to' => $toname.'<'.$to.'>',
        'cc' => '',
        'bcc' => '',
        'subject' => $subject,
        'html'=>$html,
        'text'=>$text,
        'o:tracking'=>'yes',
        'o:tracking-clicks'=>'yes',
        'o:tracking-opens'=>'yes',
        'o:tag'=>$tag,
        'h:Reply-To'=>$replyto,
    );
    if(sizeOf($attachment) > 0){
        $i=0;
        foreach ($attachment as $attach){
            $attachPath = substr($attach, strrpos($attach, '/public/') + 1);
            $post['attachment['.$i.']'] = curl_file_create($attach, '', substr($attachPath, strrpos($attachPath, '/') + 1));
            $i=$i+1;
        }
    }
    $headers_arr = array("Content-Type:multipart/form-data");
    curl_setopt($ch, CURLOPT_POSTFIELDS, $post);
    curl_setopt($ch, CURLOPT_USERPWD, 'api' . ':' . $key);
    curl_setopt($ch, CURLOPT_HEADER, $headers_arr);
    curl_setopt($ch, CURLOPT_ENCODING, 'UTF-8');
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
    
    $result = curl_exec($ch);
    
    
    if (curl_errno($ch)) {
        $result = curl_error($ch);
        \Log::info($result);
    }
    else{
        $result = json_decode($result,true);
    }
    curl_close($ch);
   
    \Log::info($result);
    return $result;
