$this->email->to(
        array('[email protected]', '[email protected]', '[email protected]')

cc($cc)

Parameters:	$cc (mixed) – Comma-delimited string or an array of e-mail addresses

Sets the CC email address(s). Just like the “to”, can be a single e-mail, a comma-delimited list or an array.

bcc($bcc[, $limit = ''])

Parameters:	$bcc (mixed) – Comma-delimited string or an array of e-mail addresses $limit (int) – Maximum number of e-mails to send per batch
Returns:	CI_Email instance (method chaining)
Return type:	CI_Email

Sets the BCC email address(s). Just like the to() method, can be a single e-mail, a comma-delimited list or an array.

If $limit is set, “batch mode” will be enabled, which will send the emails to batches, with each batch not exceeding the specified $limit.

subject($subject)

Parameters:	$subject (string) – E-mail subject line
Returns:	CI_Email instance (method chaining)
Return type:	CI_Email

Sets the email subject:

$this->email->subject('This is my subject');

message($body)

Parameters:	$body (string) – E-mail message body
Returns:	CI_Email instance (method chaining)
Return type:	CI_Email

Sets the e-mail message body:

$this->email->message('This is my message');

set_alt_message($str)

Parameters:	$str (string) – Alternative e-mail message body
Returns:	CI_Email instance (method chaining)
Return type:	CI_Email

Sets the alternative e-mail message body:

$this->email->set_alt_message('This is the alternative message');

This is an optional message string which can be used if you send HTML formatted email. It lets you specify an alternative message with no HTML formatting which is added to the header string for people who do not accept HTML email. If you do not set your own message CodeIgniter will extract the message from your HTML email and strip the tags.

set_header($header, $value)

Parameters:	$header (string) – Header name $value (string) – Header value
Returns:	CI_Email instance (method chaining)
Return type:	CI_Email

Appends additional headers to the e-mail:

$this->email->set_header('Header1', 'Value1');
$this->email->set_header('Header2', 'Value2');

clear([$clear_attachments = FALSE])

Parameters:	$clear_attachments (bool) – Whether or not to clear attachments
Returns:	CI_Email instance (method chaining)
Return type:	CI_Email

Initializes all the email variables to an empty state. This method is intended for use if you run the email sending method in a loop, permitting the data to be reset between cycles.

foreach ($list as $name => $address)
{
        $this->email->clear();

        $this->email->to($address);
        $this->email->from('[email protected]');
        $this->email->subject('Here is your info '.$name);
        $this->email->message('Hi '.$name.' Here is the info you requested.');
        $this->email->send();
}

If you set the parameter to TRUE any attachments will be cleared as well:

$this->email->clear(TRUE);

send([$auto_clear = TRUE])

Parameters:	$auto_clear (bool) – Whether to clear message data automatically
Returns:	TRUE on success, FALSE on failure
Return type:	bool

The e-mail sending method. 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.

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

Parameters:	$filename (string) – File name $disposition (string) – ‘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 $newname (string) – Custom file name to use in the e-mail $mime (string) – MIME type to use (useful for buffered data)
Returns:	CI_Email instance (method chaining)
Return type:	CI_Email

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');

attachment_cid($filename)

Parameters:	$filename (string) – Existing attachment filename
Returns:	Attachment Content-ID or FALSE if not found
Return type:	string

Sets and returns an attachment’s Content-ID, which enables your to embed an inline (picture) attachment into HTML. First parameter must be the already attached file name.

$filename = '/img/photo1.jpg';
$this->email->attach($filename);
foreach ($list as $address)
{
        $this->email->to($address);
        $cid = $this->email->attachment_cid($filename);
        $this->email->message('<img src="cid:'. $cid .'" alt="photo1" />');
        $this->email->send();
}

Note

Content-ID for each e-mail must be re-created for it to be unique.

print_debugger([$include = array('headers', 'subject', 'body')])

Parameters:	$include (array) – Which parts of the message to print out
Returns:	Formatted debug data
Return type:	string

Returns a string containing any server messages, the email headers, and the email messsage. Useful for debugging.

You can optionally specify which parts of the message should be printed. Valid options are: headers, subject, body.

Example:

// You need to pass FALSE while sending in order for the email data
// to not be cleared - if that happens, print_debugger() would have
// nothing to output.
$this->email->send(FALSE);

// Will only print the email headers, excluding the message subject and body
$this->email->print_debugger(array('headers'));

Note

By default, all of the raw data will be printed.
