PHP Mailer and Codeigniter 3

1. installing PHP Mailer

Download the latest PHPMailer Build from Github. You can find the project here

Click now on "clone or download" and download it as zip - as in the image below is shown. 

The folder in the zip is called PHPMailer-master. Unzip this in your application/third_party/ folder and rename the folder to phpmailer. You should see something like this 

2. PHP Mailer Library

Imho its best to create a library which handles your PHPMailer Object (PHPMailer_Library.php) This library could look like

class PHPMailer_Library
{
    public function __construct()
    {
        log_message('Debug', 'PHPMailer class is loaded.');
    }

    public function load()
    {
        require_once(APPPATH."third_party/phpmailer/PHPMailerAutoload.php");
        $objMail = new PHPMailer;
        return $objMail;
    }
}

3. Using this library in one of your controllers, models etc.

class Welcome extends CI_Controller {


    public function index()
    {
        $this->load->library("phpmailer_library");
        $objMail = $this->phpmailer_library->load();
    }
}

i think this should pretty much do the job. If you've any troubles, don't hesitate to ask ;)
