Undefined property: stdClass::$bytes

[joshralph93]

Hi there,

I'm getting the following error when an email has an attachment of 0 bytes Undefined property: stdClass::$bytes

Attachment.php:101

$this->size = $structure->bytes;


I've wrapped it in an isset, which to gets rid of the error, but not sure if this size is required elsewhere?

Did the same to "fix" this issue, please take a look into it and make a proper fix?

I wrapped that line in isset

Attachment.php:101

  if (isset($structure->bytes)) {
            $this->size = $structure->bytes;
        } else {
            $this->size = 0; // _mysql complained on null so I made the size 0_
        }

but now get some odd output and more attachments than were actually attached to the email

Here are my attachments

Number of attachments = 8 in total

Here is my debug code in this function

Attachment.php saveAS() function

   /**
     * This function saves the attachment to the exact specified location.
     *
     * @param  string $path
     * @return bool
     */
    public function saveAs($path)
    {
        $encoding = $this->encoding;
        $dirname = dirname($path);
        if (file_exists($path)) {
            if (!is_writable($path)) {
                return false;
            }
        } elseif (!is_dir($dirname) || !is_writable($dirname)) {
            return false;
        }

        if (($filePointer = fopen($path, 'w')) == false) {
            return false;
        }
        **echo "ATTACHMENT.PHP saveAs() filePointer is $filePointer.\n";**

        switch ($encoding) {
            case 3: //base64
                $streamFilter = stream_filter_append($filePointer, 'convert.base64-decode', STREAM_FILTER_WRITE);
                break;

            case 4: //quoted-printable
                $streamFilter = stream_filter_append($filePointer, 'convert.quoted-printable-decode', STREAM_FILTER_WRITE);
                break;

            default:
                $streamFilter = null;
        }

Here is the debug output

and here are my attachments saved in my application.

It's hard to see exactly how many are being attached - there are 14 font awesome file/document icons and 17 delete icons (red x's) so does anybody have a clue why there are more attachments being created than actual real attachments?

I think it's got something to do with reading the structure of each section to find any attachments in each section.

Attachments.php:14

/**
 * This library is a wrapper around the Imap library functions included in php. This class wraps around an attachment
 * in a message, allowing developers to easily save or display attachments.
 *
 * @package Fetch
 * @author  Robert Hafner <tedivm@tedivm.com>
 */
class Attachment
{

    /**
     * This is the structure object for the piece of the message body that the attachment is located it.
     *
     * @var \stdClass
     */
    protected $structure;

    /**
     * This is the unique identifier for the message this attachment belongs to.
     *
     * @var int
     */
    protected $messageId;

    /**
     * This is the ImapResource.
     *
     * @var resource
     */
    protected $imapStream;

    /**
     * This is the id pointing to the section of the message body that contains the attachment.
     *
     * @var int
     */
    protected $partId;

    /**
     * This is the attachments filename.
     *
     * @var string
     */
    protected $filename;

    /**
     * This is the size of the attachment.
     *
     * @var int
     */
    protected $size;

    /**
     * This stores the data of the attachment so it doesn't have to be retrieved from the server multiple times. It is
     * only populated if the getData() function is called and should not be directly used.
     *
     * @internal
     * @var array
     */
    protected $data;

Clearly the above variables show this file handles attachments.

Help would be appreciated!

PS. This function's comments are incomplete so it's not easy to understand

Message.php:702

//        print_r($this->attachments);
//        echo "\n";

        if (!isset($this->attachments) || count($this->attachments) < 1)
            return false;

        if (!isset($filename))
            return $this->attachments;

        $results = array();
        foreach ($this->attachments as $attachment) {
            if ($attachment->getFileName() == $filename)
                $results[] = $attachment;
        }

        switch (count($results)) {
            case 0:
                return false;

            case 1:
                return array_shift($results);
