ms graph php sdk message object fails to check if there are attachments

Question

I am retrieving messages from an Outlook account. I am trying to get inline files and attachments from those messages. $graph = new Graph(); $graph->setAccessToken($this->getAccessToken()); $messageQueryParams = array ( "\$select" => "subject,receivedDateTime,from,sentDateTime,body,toRecipients,sender,uniqueBody,ccRecipients,bccRecipients,attachments", "\$orderby" => "receivedDateTime DESC", "\$top" => "200" ); $url = '/me/mailfolders/' . $folder . '/messages/delta'; $url_combiner = '?'; $getMessagesUrl = $url . $url_combiner . http_build_query($messageQueryParams); $response = $graph->createRequest('GET', $getMessagesUrl)->execute(); $messages = $response->getResponseAsObject( \Microsoft\Graph\Model\Message::class ); foreach($messages as $msg) { echo $msg->getHasAttachments(); } This code returns 'null' for $msg->getHasAttachments(); I would expect it to return a true or false. The messages I am downloading from this folder have both inline attachments and mail attachments, so I am looking for a solution to both. (Responses that point to specific points in the MS Graph PHP SDK documentation are very appreciated.)

Answer 1

This is the expected behavior, in your case getHasAttachments() method returns null since hasAttachments is not included in $select query option and therefore it is not requested from a server. It needs to be explicitly included, for example: $messageQueryParams = array ( "\$select" => "hasAttachments,...", //another params are omitted for clarity ); Then whether a message contains attachments or not could be determined like this: foreach($messages as $msg) { if($msg->getHasAttachments() == true){ //... } There is one more issue with the provided example, to retrieve Message.attachments reference property (or relationship property) it needs to be specified via $expand query string parameter instead of $select (refer official documentation for a more details), like this: $messageQueryParams = array ( "\$expand" => "attachments", //another params are omitted for clarity ); Then attachments collection could be iterated like this: foreach($messages as $msg) { foreach($msg->getAttachments() as $attachment) { //... } }
