🔰 PHP Programming Tutorial 19 - Send Email using PHPMailer in CodeIgniter 4 🔰

Overview

In this example, I am going to show you how to send Email using PHPMailer in CodeIgniter.

For sending Email in CodeIgniter, we use an external library PHPMailer. By using composer you can download this library into your project.

You need to run following command in your project's root directory.

Example:

composer require phpmailer/phpmailer

Here, we are using 3 files for generating PDF file:

Controller: 	Email.php           app\Controllers\Email.php View:		compose.php         app\Views\compose.php

app/Config/Routes.php

$routes->add('email/compose', 'Email::compose'); $routes->post('email/send-email', 'Email::send_email');

app/Controllers/Email.php

<?php namespace App\Controllers;  use App\Controllers\BaseController; use PHPMailer\PHPMailer\PHPMailer; use PHPMailer\PHPMailer\Exception;  class Email extends BaseController {          public function __construct() { 		     }          public function compose() {              echo view('compose');          }          public function send_email() {              $email          = $this->request->getPost('email');         $subject        = $this->request->getPost('subject');         $message        = $this->request->getPost('message');                  $mail = new PHPMailer(true);   		try { 		     		    $mail->isSMTP();   		    $mail->Host         = 'host'; //smtp.google.com 		    $mail->SMTPAuth     = true;      		    $mail->Username     = 'username';   		    $mail->Password     = 'password'; 			$mail->SMTPSecure   = 'tls';   			$mail->Port         = 587;   			$mail->Subject      = $subject; 			$mail->Body         = $message; 			$mail->setFrom('username', 'display_name'); 			 			$mail->addAddress($email);   			$mail->isHTML(true);       			 			if(!$mail->send()) { 			    echo "Something went wrong. Please try again."; 			} 		    else { 			    echo "Email sent successfully."; 		    } 		     		} catch (Exception $e) { 		    echo "Something went wrong. Please try again."; 		}              }      }

app/Views/compose.php

<form action="<?php echo base_url('email/send-email') ?>" class="form-horizontal" id="add_email_form" autocomplete="off" method="post" accept-charset="utf-8">     <div class="form-group">         <label for="inputName" class="col-sm-2 control-label">Recipient Email</label>         <div class="col-sm-10">             <input type="hidden" name="id" value="9" id="id" />             <input type="hidden" name="source_id" value="2" id="source_id" />             <input type="text" name="email" value="" id="email" placeholder="Recipient Email Address" class="form-control" required />         </div>     </div>     <div class="form-group">         <label for="inputName" class="col-sm-2 control-label">Subject</label>         <div class="col-sm-10">             <input type="text" name="subject" value="" id="subject" placeholder="Subject" class="form-control" required />         </div>     </div>     <div class="form-group">         <label for="inputName" class="col-sm-2 control-label">Message</label>         <div class="col-sm-10">             <textarea class="form-control" name="message" id="message"></textarea>         </div>     </div>     <div class="form-group">         <div class="col-sm-offset-2 col-sm-10">             <button type="submit" class="btn btn-info">Send Email</button>         </div>     </div> </form>
