Mailgun Sent mail With attachment

Question 1

You need to change the last parameter in the following way: attachment[1]' => '@aaa.rar

We have some samples in our documentation for this use case. Just click PHP in the top bar to switch the language. http://documentation.mailgun.net/user_manual.html#examples-sending-messages-via-http

Please don't hesitate to send us an email with any questions to support@mailgunhq.com. We are always happy to help.

Question 2

I realise this is old but I've just run into this problem and this page is pretty much the only info I can find on the net. So I hope this will assist someone else. After talking to MailGun support I've found the following works with the current API.

Cycles through an array of zero to n attachment files:

    $attachmentsArray = array('file1.txt', 'file2.txt');
    $x = 1;
    foreach( $attachmentsArray as $att )
    {
        $msgArray["attachment[$x]"] = curl_file_create( $att );
        $x ++;
    }

    // relevant cURL parameter, $msgArray also contains to, from, subject  parameters etc.
    curl_setopt($ch, CURLOPT_POSTFIELDS,$msgArray);

Question 3

The documentation doesn't say it explicitly, but the attachment itself is bundled into the request as multipart/form-data.

The best way to debug what's going on is use Fiddler to watch the request. Make sure you accept Fiddler's root certificate, or the request won't issue due to the SSL error.

What you should see in Fiddler is for Headers:

Cookies / Login

Authorization: Basic <snip>==

Entity

Content-Type: multipart/form-data; boundary=<num>

And for TextView:

Content-Disposition: form-data; name="attachment"
@Test.pdf

Content-Disposition: form-data; name="attachment"; filename="Test.pdf"
Content-Type: application/pdf
<data>

Note that you POST the field 'attachment=@<filename>'. For form-data, the field name is also 'attachment', then has 'filename=<filename>' (without the '@') and finally the file contents.

I think CURL is supposed to just do this all for you magically based on using the '@' syntax and specifying a path to a file on your local machine. But without knowing the magic behavior it's hard to grok what's really happening.

For example, in C# it looks like this:

public static void SendMail(MailMessage message) {
    RestClient client = new RestClient();
    client.BaseUrl = apiUrl;
    client.Authenticator = new HttpBasicAuthenticator("api", apiKey);

    RestRequest request = new RestRequest();
    request.AddParameter("domain", domain, ParameterType.UrlSegment);
    request.Resource = "{domain}/messages";
    request.AddParameter("from", message.From.ToString());
    request.AddParameter("to", message.To[0].Address);
    request.AddParameter("subject", message.Subject);
    request.AddParameter("html", message.Body);

    foreach (Attachment attach in message.Attachments)
    {
        request.AddParameter("attachment", "@" + attach.Name);
        request.AddFile("attachment",
            attach.ContentStream.WriteTo,
            attach.Name,
            attach.ContentType.MediaType);
    }

    ...
    request.Method = Method.POST;
    IRestResponse response = client.Execute(request);
}

Question 4

I got stuck on this issue for a while and the answers here helped me, but there is something I came across which is not mentioned yet.

I had been sending my POST parameters with a blank/NULL 'cc' value, such as: $post_data['cc'] = NULL;. This did not prevent me from sending text emails (no attachment), but it did cause problems when sending an email with an attachment. Removing the blank cc from my array resolved part of the issue.

Additionally I had been using http_build_query before posting my data via PHP curl and that prevented my email with attachment from being sent successfully.

Removing the empty cc and http_build_query resolved this for me. Maybe an uncommon case, but posting in case it is helpful for someone who has the same issue.

Question 5

Add attachment file:

"attachment[1]" = "@$_FILES['careerDocument']['tmp_name'];filename=test.jpg".
($contentType ? ';type=' . $contentType : '' ) ;
curl_setopt($ch, CURLOPT_POSTFIELDS, ($message));

Question 6

Thsi worked for me:

<?php

$filePath='@Wealth_AC_AMF.pdf';

$curl_post_data=array(
    'from'    => 'Excited User <noreply@test.com>',
    'to'      => 'test@gmail.com',
    'subject' => 'Hello',
    'text'    => 'test',
'attachment[1]' => $filePath
);

$service_url = 'https://api.mailgun.net/v3/test.com/messages';
$curl = curl_init($service_url);
curl_setopt($curl, CURLOPT_HTTPAUTH, CURLAUTH_BASIC);
curl_setopt($curl, CURLOPT_USERPWD, "api:key-test"); 

curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_POST, true);

curl_setopt($curl, CURLOPT_POSTFIELDS, $curl_post_data);
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false); 


$curl_response = curl_exec($curl);  
$response = json_decode($curl_response);
curl_close($curl);

var_dump($response);



 ?>

Question 7

This worked for me...

class Email {

    function send($array, $file_array) {
        $mgClient = new Mailgun('YOUR_MAILGUN_API_KEY');
        $domain = "mg.YOUR_DOMAIN.com";
        $result = $mgClient->sendMessage($domain, $array, array('attachment' => $file_array));
        return $result;
    }   
}

$array = array(
    'from'    => 'From <from@from.com>',
    'to'      => 'To <to@to.com>',
    'subject' => 'Your Subject',
    'html'    => '<h1>Hooray!</h1>',
);

$file_array = array('/var/www/scripts/test.csv');
echo json_encode($Email::send($array, $file_array));

Question 8

This is working fine for me.

require '../../vendor/autoload.php';
use Mailgun\Mailgun;

# Instantiate the client.
$mgClient = new Mailgun('key-b0e955');
$domain = "domain.com";

# Make the call to the client.
$result = $mgClient->sendMessage("$domain",
  array('from'    => '<postmaster@domain.com>',
        'to'      => '<test@gmail.com>',
        'subject' => 'csv file',
        'text' => 'csv test file'
       ),array('attachment' => [
    ['remoteName'=>'student.csv', 'filePath'=>'/form/stu.csv']
  ]) );

Question 9

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;
