Retrieving attachments from forwarded message with embedded attachment about php-ews

[Garethp]

I can see a couple of possible problems here. The first is that you're not getting the right mailItem. You say there's only 1 message in the mailbox, and you're right, the array of MailItems only has one item in the array. So $mailItem = $mail[1]; should be $mailItem = $mail[0];

Secondly, there are two kinds of attachments. Email attachments and File Attachments. In your original post on james' repo, you were trying to get an ItemAttachment, not a FileAttachment. Can you do a var_dump on $mailItem->getAttachments() ?

In order to get an ItemAttachment, you should instead do $itemAttachment= $mailItem->getAttachments()->getItemAttachment()[0]; In a release in the next week there'll be a way to get both ItemAttachments and FileAttachments in one go, but for the moment you need to get them separately like this.

Sorry about the rookie mistake with the mailItem. I have corrected it and I am able to get the attachment's name and content type, but not the content itself (to save to a file).

Here's the php file:
require_once "vendor/autoload.php";
use jamesiarmes\PEWS\API\Type;
use jamesiarmes\PEWS\Mail\MailAPI;
$api = MailAPI::withUsernameAndPassword($server, $username, $password);

$mail = $api->getMailItems();

$mailItem = $mail[0];
$mailItem = $api->getItem($mailItem->getItemId());

var_dump($mailItem->getAttachments() );

$itemAttachment= $mailItem->getAttachments()->getItemAttachment()[0];
//var_dump ($itemAttachment);

$attachment = $api->getAttachment($itemAttachment->getAttachmentId());
$name = $attachment->getName();
$contentType = $attachment->getContentType();
////The line below errors out
$content = $attachment->getContent();

echo "The name is $name, the type is $contentType\n";

here is the php_error log:

Okay, so if you take a look at ItemAttachmentType class and the Microsoft Documentation, you see that ItemAttachments and FileAttachments don't work in the same way.

Rather than having a content like FileAttachments, it has the Item directly. For example, if you're attaching a Mail Message (MessageType) to another mail, when you get your ItemAttachment you can do $itemAttachment->getMessage()->getSubject() to get the subject. Or if the attachment is a Calendar Item, you can do $itemAttachment->getCalendarItem()->getStart() to get the start time.

I'm still investigating this, and I'll probably include a feature to make it easier to get the item soon, but first I need to be able to analyze an email that has one of these ItemAttachments attached to it. For now, this should work. So it turns out that there's a good reason that FileAttachments and ItemAttachments are separated

[Garethp]

That being said, looking at this stackoverflow answer, there could be a way of saving the item. Maybe something like $content = base64_encode((string) $itemAttachment->getMessage()->getMimeContent()); but I can't confirm that yet and it's untested, just a theory

Okay, so if you run on the dev-master branch of this library, you'll be able to save ItemAttachments now. It'll be included in the next release, but dev-master now includes MimeContent of ItemAttachments. So you should be able to save attachments like

$attachments = $item->getAttachments();
$itemAttachment = $attachments[0]->getItemAttachment();
$itemAttachment = $api->getAttachment($itemAttachment->getAttachmentId());

$contentType = $itemAttachment()->getContentType();
$content = (string) $itemAttachment()->getItemAttachment()->getMimeContent();

You'll have to figure out the file extension on your own though

Garethp, Thank you for all your assistance. I verified I was able to get access to the attached message's attachments!

I sincerely appreciate your time and effort. Now I need to convert my old script from the original fork to use your fork for everything (e.g. moving messages to a folder, reply-all, etc).

Here is the final snippet that worked for me.

$attachments = $mailItem->getAttachments();
$theItemAttachment = $attachments->getItemAttachment();

$itemAttachment = $api->getAttachment($theItemAttachment[0]->getAttachmentId());

$contentType = $itemAttachment->getContentType();
$content = base64_decode((string) $itemAttachment->getItemAttachment()->getMimeContent());

///Use https://github.com/php-mime-mail-parser/php-mime-mail-parser to extract the MIME attachments to a file(s)

While I don't have a Reply-All function, you can use the API::moveItem() function for moving emails. If there's any other features you come across that you use constantly, let me know and I'll see what I can do to build it in.
