Attachment id issue

[klysiak]

Hi,

I received an email with attachments and those were not recognized by your library.
The issue was that originally imap_fetchstructure got the following:

[type] => 3 [encoding] => 3 [ifsubtype] => 1 [subtype] => PDF [ifdescription] => 0 [ifid] => 1 [id] => <> [bytes] => 277320 [ifdisposition] => 1 [disposition] => attachment [ifdparameters] => 1
Your code:
$attachmentId = $partStructure->ifid ? trim($partStructure->id, " <>") : (isset($params['filename']) || isset($params['name']) ? mt_rand() . mt_rand() : null);

was generating empty $attachmentId so if($attachmentId) returned false and the attachments were not processed.

Temporarily I added
$attachmentId = $partStructure->ifid ? ((trim($partStructure->id, " <>") != '')?trim($partStructure->id, " <>"):mt_rand() . mt_rand()) : (isset($params['filename']) || isset($params['name']) ? mt_rand() . mt_rand() : null);

and it is working. I will check if it is causing any further issues.

Maybe you have better suggestion?

This is a very bad construction

[yiioverflow]

Yes. So I didnt merged it yet.

I would suggest doing so, but check:

    /**
     * @param object $structure
     * @param array $params
     * @return string|null
     */
    public static function getAttachmentId($structure, $params): ?string
    {
        if ($structure->ifid && !empty(trim($structure->id, " <>"))) {
            $attachmentId = trim($structure->id, " <>");
        } elseif (isset($params['filename']) || isset($params['name'])) {
            $attachmentId = mt_rand() . mt_rand();
        } else {
            $attachmentId = null;
        }

        return $attachmentId;
    }

Hello. If the name of the attached file is too long, then the OS does not allow it to be saved. Can the file name be generated randomly, for example through the uniqid function? It would be nice not to save the files, but to get its contents through the method.

Yes it would be nice. We check the length of the file, if it is too large, then we replace it with a unique value
