Returns boolean TRUE or FALSE based on - success or failure, enabling it to be used conditionally:: - - if ( ! $this->email->send()) - { - // Generate error - } - - This method will automatically clear all parameters if the request was - successful. To stop this behaviour pass FALSE:: - - if ($this->email->send(FALSE)) - { - // Parameters won't be cleared - } - - .. note:: In order to use the ``print_debugger()`` method, you need - to avoid clearing the email parameters. - - .. php:method:: attach($filename[, $disposition = ''[, $newname = NULL[, $mime = '']]]) - - :param string $filename: File name - :param string $disposition: 'disposition' of the attachment. Most - email clients make their own decision regardless of the MIME - specification used here. https://www.iana.org/assignments/cont-disp/cont-disp.xhtml - :param string $newname: Custom file name to use in the e-mail - :param string $mime: MIME type to use (useful for buffered data) - :returns: CI_Email instance (method chaining) - :rtype: CI_Email - - Enables you to send an attachment.
