Well I wanted to call this library/plugin Freak_Swift_Mailer, but then& somebody killed my creativity&

Anyway, this is my solution for using SWIFT MAILER library with CI.

RESOURCES:

=> FORUM

=> official SWIFT MAILER WEBSITE

=> 4webby.com for tutorials

REQUIREMENTS:

- CodeIgniter 1.5.1/1.5.2 (http://www.codeigniter.com/download.php)

INSTALLATION:

1. download SWIFT MAILER from SWIFT MAILER website (choose PHP4 or PHP5 version according to your needs)
2. unzip Swift-X.0.X-phpX.zip in a local folder
3. create a folder called my_classes in your system/application directory
4. copy the files INSIDE the folder Swift-X.0.X-phpX/lib/ in your system/application/my_classes/ directory
5. enable hooks in your application/config/config.php file
   
6. /*
|--------------------------------------------------------------------------
| Enable/Disable System Hooks
|--------------------------------------------------------------------------
|
| If you would like to use the "hooks" feature you must enable it by
| setting this variable to TRUE (boolean). See the user guide for details.
|
*/
$config['enable_hooks'] = TRUE;

7. add the following lines in application/config/hooks.php
8. $hook['pre_controller'][] = array(
'class' => 'MyClasses',
'function' => 'index',
'filename' => 'MyClasses.php',
'filepath' => 'hooks'
);

9. in your system/application/hooks/ create a new file called MyClasses.php with the following inside
10. <?php
if (!defined('BASEPATH')) exit('No direct script access allowed');

class Myclasses
{
/**
* includes the directory application\my_classes\ in your includes directory
*
*/
function index()
{
//includes the directory application\my_classes\Swift\
ini_set('include_path', ini_get('include_path').':'.BASEPATH.'application/my_classes/');
}
}
?>


    Be carefull to change the colon ':' to semicolon ';' if you use the above hook on Windows server/local server
    
    Windows example:
    //Windows
ini_set('include_path', ini_get('include_path').';'.BASEPATH.'application/my_classes/')
    
    Linux example:
    //Linux
ini_set('include_path', ini_get('include_path').':'.BASEPATH.'application/my_classes/')

11. build a controller to test that everything works fine (example taken here)
12. class Mail extends Controller
{
function Mail()
{
parent::Controller();

}

function index()
{
//Load in the files we'll need
require_once "Swift.php";
require_once "Swift/Connection/SMTP.php";

//Start Swift
$swift =& new Swift(new Swift_Connection_SMTP("your.smtp.com"));

//Create the message
$message =& new Swift_Message("My subject", "My body");

//Now check if Swift actually sends it
if ($swift->send($message, "recipient@email.com", "sender@email.com")) echo "Sent";
else echo "Failed";
}
}

?>

13. now build other controllers/methods to suit your needs. Check out the SWIFT MAILER DOCUMENTATION

14. use the examples in the documentation, but change
    //Load in the files we'll need
require_once "lib/Swift.php";
require_once "lib/Swift/Connection/SMTP.php";
    to
    //Load in the files we'll need
require_once "Swift.php";
require_once "Swift/Connection/SMTP.php";

15. HAPPY CODING!
