How to integrate PHPMailer with Codeigniter 3

Question

Hi I am trying to use PHPMailer Library from GitHUB in my Codeigniter application.

I downloaded the code and unzipped in my application\library folder. So there I have a folder called vendor inside which resides the source code for PHPMailer.

Now I created a File named Bizmailer_Controller.php.

<?php defined('BASEPATH') OR exit('No direct script access allowed');

/**
* 
*/
class Bizmailer_Controller extends CI_Controller
{

    public function __construct()
    {
        parent::__construct();

        require "vendor\phpmailer\phpmailer\PHPMailerAutoload";
        $this->Bizmailer = new PHPMailer();
        //Set the required config parameters
        $this->Bizmailer->isSMTP();                                      // Set mailer to use SMTP
        $this->Bizmailer->Host = 'smtp1.example.com;smtp2.example.com';  // Specify main and backup SMTP servers
        $this->Bizmailer->SMTPAuth = true;                               // Enable SMTP authentication
        $this->Bizmailer->Username = '[email protected]';                 // SMTP username
        $this->Bizmailer->Password = 'secret';                           // SMTP password
        $this->Bizmailer->SMTPSecure = 'tls';                            // Enable TLS encryption, `ssl` also accepted
        $this->Bizmailer->Port = 465;    
        //return $api;
    }
}

Now in my controllers I am trying to load it like this :

$this->load->library('Bizmailer');
$mail = new Bizmailer();

And I Get this error :

An Error Was Encountered

Unable to load the requested class: Bizmailer

So Please guide me how I can load or integrate this library in Codeigniter.

Answer 1

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
