I just figured I'd pass along a quick little hack that will allow image attachments to take advantage of the new "image" tag that is part of the Mandrill API.
In the mail.php plug-in script add a new array for image attachments. I called mine "$iAttachments"
private function mandrillSend()
{
$action = 'send';
$to = array();
$attachments = $this->GetAttachments();
$mAttachments = array(); //file attachments
$iAttachments = array(); //image attachments //<--- add this image array
if(count($attachments) > 0) {
Add an "image" match conditional on $mime_type as shown below:
if(count($attachments) > 0) {
foreach($attachments as $attachment) {
// a lot of people are setting wrong mime_type when using the addAtachment function
// let us try to determine the mime_type ourselves on the base of the filename
//
$mime_type = $this->detectMimeType($attachment[1]);
if(!$mime_type) {
$this->writeToLog(JText::sprintf('PLG_SYSTEM_MANDRILL_UNSUPPORTED_ATTACHMENT', $attachment[2], $mime_type));
// if one of the files is not an image/txt or pdf, then use standard phpmailer
// the mandrill api doesn't support other formats right now
$this->phpMailerSend();
};
//<--- look for attachments with mime type of "image"
//<--- add these images to the new $iAttachment array
if (preg_match('/^image/',$mime_type)) {
$iAttachments[] = array(
'name' => $attachment[2],
'type' => $mime_type,
'content' => $this->EncodeFile($attachment[0])
);
//<--- any other attachments get added to the original $mAttachments array, as per normal
} else {
$mAttachments[] = array(
'name' => $attachment[2],
'type' => $mime_type,
'content' => $this->EncodeFile($attachment[0])
);
}
}
}
Assign to the mandrill message object a new "images" array using the new $iAttachments
if(count($mAttachments)) {
$mandrill->message['attachments'] = $mAttachments;
}
//<--- assign $iAttachments to a new mandrill message "images" array.
if(count($iAttachments)) {
$mandrill->message['images'] = $iAttachments;
}
Now, image attachements will be given a "Content-Disposition" of "inline" as opposed to "attachment" and will display in html messages properly.
