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 <[email protected]>',
                    'to' => '[email protected]',
                    '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": "<[email protected]>",
    "message": "Queued. Thank you."
}"

Within the mailgun logs no attachments are listed:

"message": {
    "headers": {
        "to": "[email protected]",
        "message-id": "[email protected]",
        "from": "Example <[email protected]>",
        "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';
$parameters = array('from' => 'Example <[email protected]>',
                'to' => '[email protected]',
                'subject' => 'Subject',
                'text' => 'This is just a test.',
                'attachment[1]' => curl_file_create($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.

Thanks, that helped a lot. – Dulci

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 );

This does not work, it sends email but does not send attachment with that. – Candescent

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("[email protected]","Recipeint Name", "Sender Name", "[email protected]","Email subject","Email body. find two attachment","","tags", "[email protected]", $path);
  echo "<pre>".print_r($res, true)."</pre>";

$dest = "filepath/test.pdf";
$result = $mgClient->messages()->send($domain,
            array('from'    => 'Tester <[email protected]>',
              'to'      => '[email protected]',
              '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;

On Stack Overflow, the how is important, but a great part of the quality level of the site comes from the fact that people go to great lengths to explain the why. While a code-only answer get the person who asked the question past whatever hurdle they might be facing, it doesn't do them or future visitors much good in the long run.
