CI_Email::attach()

attach($filename[, $disposition = ''[, $newname = NULL[, $mime = '']]])

Enables you to send an attachment. Put the file path/name in the first parameter. For multiple attachments use the method multiple times. For example:

$this->email->attach('/path/to/photo1.jpg');
$this->email->attach('/path/to/photo2.jpg');
$this->email->attach('/path/to/photo3.jpg');

To use the default disposition (attachment), leave the second parameter blank, otherwise use a custom disposition:

$this->email->attach('image.jpg', 'inline');

You can also use a URL:

$this->email->attach('http://example.com/filename.pdf');

If you’d like to use a custom file name, you can use the third paramater:

$this->email->attach('filename.pdf', 'attachment', 'report.pdf');

If you need to use a buffer string instead of a real - physical - file you can use the first parameter as buffer, the third parameter as file name and the fourth parameter as mime-type:

$this->email->attach($buffer, 'attachment', 'report.pdf', 'application/pdf');
