? How do I email a LINK from this Codeigniter 3 form? ?

I am working on a basic blog application in Codeigniter 3.1.8 and Bootstrap 4.

I have added a registration and login system to this application. I am current working on a password reset system.

I was able to do these 2 things separately:

Send a password reset email containing dummy text.
Create a valid password reset link.
I was unable however, to send the email once the reset link was inserted into the email body.

Here is he controller:

PHP Code:

class Newpassword extends CI_Controller {
    public function __construct()
    {
        parent::__construct();
    }

    private $sender_email = "[email protected]";
    private $sender_name = "Razvan Zamfir";
    private $user_email = '';
    private $subject = 'Pasword reset link';
    private $reset_token = '';
    private $reset_url = '';
    private $reset_link = '';
    private $body = '';

    public function index() {
        // Display form
        $data = $this->Static_model->get_static_data();
        $data['pages'] = $this->Pages_model->get_pages();
        $data['tagline'] = 'Reset your password';
        $data['categories'] = $this->Categories_model->get_categories();

        // Form validation rules
        $this->form_validation->set_rules('email', 'Email', 'required|trim|valid_email');
        $this->form_validation->set_error_delimiters('<p class="error-message">', '</p>');

        if(!$this->form_validation->run()) {
            $this->load->view('partials/header', $data);
            $this->load->view('auth/passwordreset');
            $this->load->view('partials/footer');
        } else {
            if ($this->Usermodel->email_exists()) {

                  //Get user email
                  $this->user_email = $this->input->post('email');

                    //create token
                    $this->reset_token = md5(str_shuffle($this->user_email));

                    //create url
                $this->reset_url = base_url('changepasword/') . $this->user_email . '/'. $this->reset_token;

                //create reset link
                $this->reset_link = '<a href="' . $this->reset_url . '">password reset link</a>';

                echo $this->reset_link;die();

                $this->body = "Here is your $this->reset_link. \n\nAfter clicking it you will be redirected to a page on the website where you will be able to set a new pasword.";

                // Send mail and rediect
                $this->sendResetMail();             
            } else {
                $this->session->set_flashdata('email_non_existent', "The email you provided does not exist in our database");
            }
           redirect('newpassword');
        }
    }

    public function sendResetMail() {
        // Loading the Email library
        $config['protocol'] = 'sendmail';
        $config['charset'] = 'utf-8';
        $config['mailtype'] = 'html';

        if(!$this->load->is_loaded('email')){
            $this->load->library('email', $config);
        } else {
          $this->email->initialize($config);
        }

        // Build the body and meta data of the email message
        $this->email->from($this->sender_email, $this->sender_name);
        $this->email->to($this->user_email);
        $this->email->subject($this->subject);
        
        $this->email->message($this->body);

        if($this->email->send()){
            $this->session->set_flashdata('reset_mail_confirm', "A pasword reset link was send to the email address $this->user_email");
        } else{
            $this->session->set_flashdata('reset_mail_fail', "Our atempt to send a pasword reset link to $this->user_email has failed");
        }
    }
} 


I have inspected the link, it is valid and the value of the href attribute is as intended, but once I remove echo $this->reset_link;die() I see the attempt to send the email failing:



Why?

Echo out the variable to see what it is doing.

PHP Code:

echo $this->reset_url;
exit();
