How to integrate PHPMailer with Codeigniter 3

here is a guide

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 😉

Update 25.06.2018

Since the PHPMailer guys removed the autoloader you’ve two options now:

1.) via Composer

for those who didn’t know – Codeigniter supports Composer – you simply have to activate the autoload – you can find this in your config.php

$config['composer_autoload'] = true;

For more informations take a look here

After that – run composer like

composer require phpmailer/phpmailer

You now should have within your application/vendor folder the phpmailer files.

The library should look like

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

    public function load()
    {
        $objMail = new PHPMailer\PHPMailer\PHPMailer();
        return $objMail;
    }
}

2.) download

follow step 1

The library should look like

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

    public function load()
    {
        require_once(APPPATH.'third_party/phpmailer/src/PHPMailer.php');
        require_once(APPPATH.'third_party/phpmailer/src/SMTP.php');

        $objMail = new PHPMailer\PHPMailer\PHPMailer();
        return $objMail;
    }
}

and everything else should remain the same
