Hello Readers! Here is the code to send link to your email address when you click on Forgot Password link during login in cakephp.

Create a view forgot_password.ctp and paste the below code to it:

<?php echo $this->Session->flash(); ?>
<div class="container">
    <div class="midBlock clearfix">
      <div class="col-md-12">
        <h1 class="text-center">Enter your credentials below to  <p>Reset Password</p></h1>
          <?php echo $this->Form->create('User',array('controller'=>'users','inputDefaults' => array('label' => false,'div' => false))) ;?>
            <ul class="login">
              <li>
                <?php echo $this->Form->input('email',array('type'=>'text','placeholder'=>"Enter Email")); ?>
              </li>
              <li>
                <?php echo $this->Form->submit('Send',array('class'=>'btnNew')); ?>
                <p>Click here to <a href="registration">Sign up</a> now</p>
              </li>
            </ul>
          </form>
      </div>
    </div>
  </div>

Now create a function in UserController.php:

public function forgot_password()
	{
		if (!empty($this->request->data)) {

			$result  = $this->User->find('first', array('conditions' => array('User.email' => $this->request->data['User']['email'])));
			/*Create msg*/
			$i       = 16;
			$cstrong = true;
			$bytes   = openssl_random_pseudo_bytes($i, $cstrong);
			$hex     = bin2hex($bytes);

            // print_r($result['User']['id']);die;
			$msg = '';
			$msg = 'Click the link to reset password <a href="http://localhost/htmltophp/users/reset/' . $hex .'">http://localhost/htmltophp/users/reset/' . $hex .'</a>';


			$msg .= '';

			$msg = wordwrap($msg, 70);
			try {
				$Email = new CakeEmail();
				$Email->from(array(
					'abc@example.com' => 'My Site'
					));
				$Email->to($this->request->data['User']['email']);
				$Email->subject("Forgot Password");
				$Email->send($msg);
				$this->request->data['User']['id']   = $result['User']['id'];
				$this->request->data['User']['hexkey'] = $hex;
				if ($this->User->save($this->request->data)) {
					$this->Session->setFlash('Email sent. Please check your email id');
				}
			}
			catch (Exception $e) {
				echo 'Error:' . $e->getMessage();
			}
		}

	}

WE have used CakeEmail class to send email which is new in cakephp.

Note:  Firstly add this line to UserController.php to ensure that the class is loaded.

App::uses('CakeEmail', 'Network/Email');

Next thing you are required to do is change the default function of email.php with the following code:

public $default = array(
		'transport' => 'Smtp',
		'from' => array('abc@example.com' => 'My Site'),
		'host' => 'smtpout.secureserver.net',
		'port' => 25,
		'timeout' => 30,
		'username' => 'abc@example.com',
		'password' => '',
		'client' => null,
		'log' => false,
		'emailFormat' => 'html',
		'charset' => 'utf-8',
		'headerCharset' => 'utf-8',
	);
