Hello Reader's ,

Today in my blog, I am going to explain about the mail function in CakePHP3 and how you can use it for sending a mail. It is simple to implement in your project.

First, you need to configure email transports and email delivery profiles in your config/app.php. Here i am using gmail ssl for sending a mail.

Add gmail SSl setting in Email Transport array in app.php file

 'EmailTransport' => [
        'default' => [
            'className' => 'Mail',
            // The following keys are used in SMTP transports
            'host' => 'localhost',
            'port' => 25,
            'timeout' => 30,
            'username' => 'user',
            'password' => 'secret',
            'client' => null,
            'tls' => null,
             'url' => env('EMAIL_TRANSPORT_DEFAULT_URL', null),
        ],
      'gmail'=> [
          'host' => 'ssl://smtp.gmail.com',
          'port' => 465,
          'username' => 'YourEmailID@gmail.com',  //your gmail address
          'password' => 'YourMailPassword',        //your gmail password
          'className' => 'Smtp',
          'log' => true,
          'context' => [
            'ssl' => [
                'verify_peer' => false,
                'verify_peer_name' => false,
                'allow_self_signed' => true
            ]
          ]
        ],
    ],

After completing this then add below Function in the controller.

public function send_mail()
	{		
		
		$msg='Hellow User';
		$subject='CakePHP3 Mail';
		$to=yourEmailId@domain.com;
		$true=$this->sendUserEmail($to,$subject,$msg);
		 if($true=='1')
		 {
			$this->Flash->success(__('Mail Send'));
			return $this->redirect(['action' => 'index']);
		 }
		 else
		 {
			$this->Flash->success(__('Error'));
			return $this->redirect(['action' => 'index']);
		 }
    
	}

In the above function we are passing param to another function which placed in config/appController.php.

Add Mail Library in your AppController.php file.

use Cake\Network\Email\Email;

Now add sendUserEmail () Function in appController.php

public function sendUserEmail($to,$subject,$msg)
    {
      $email = new Email();    
       $email
            ->transport('gmail')
            ->from(['yourEmailID@domain.com' => 'yourEmailID@domain.com'])
            ->to($to)
            ->subject($subject)
             ->emailFormat('html')
            ->viewVars(array('msg' => $msg))
            ->send($msg);         
            return 1;
    }
