Question

is there any way to remove an attachment from Zend_Mail object? Simple
example:

$mail = new Zend_Mail();

//..configuring the email..

$mail->createAttachment($myImage,
                        'image/gif',
                        Zend_Mime::DISPOSITION_INLINE,
                        Zend_Mime::ENCODING_BASE64);
$mail->send();

now, I would like to modify the object and send it again

$mail->clearSubject()
     ->setSubject('new subject');

is there any posibility to remove the attachment from this object that
was set previously?

Answer 1

You can do it this way:

$mail = new Zend_Mail();
$mail->createAttachment("...");

$parts = $mail->getParts();
foreach ($parts as $k => $v) {
    if ($v->disposition == "attachment") {
        unset($parts[$k]);
    }
}
$mail->setParts($parts);
$mail->hasAttachments = false;

This will only remove parts where their MIME disposition is set to attachment.
