Php 如何使用MVC方法通过电子邮件重置密码？

在我的控制器中，一个Login.php：

/*     * *RESET AND SEND PASSWORD TO REQUESTED EMAIL*** */

function reset_password() {
    $account_type = $this->input->post('account_type');
    if ($account_type == "") {
        redirect(base_url(), 'refresh');
    }
    $email = $this->input->post('email');
    $result = $this->email_model->password_reset_email($account_type, $email); //SEND EMAIL ACCOUNT OPENING EMAIL
    if ($result == true) {
        $this->session->set_flashdata('flash_message', get_phrase('password_sent'));
    } else if ($result == false) {
        $this->session->set_flashdata('flash_message', get_phrase('account_not_found'));
    }

    redirect(base_url(), 'refresh');
}

在我的电子邮件_model.php中：

function account_opening_email($account_type = '', $email = '') 
{
  $system_name = $this->db->get_where('settings', array('type' => 'system_name'))->row()->description;

    $email_msg = "Welcome to " . $system_name . "<br />";
    $email_msg .= "Your account type : " . $account_type . "<br />";
    $email_msg .= "Your login password : " . $this->db->get_where($account_type, array('email' => $email))->row()->password . "<br />";
    $email_msg .= "Login Here : " . base_url() . "<br />";

    $email_sub = "Account opening email";
    $email_to = $email;

    $this->do_email($email_msg, $email_sub, $email_to);
}

function password_reset_email($account_type = '', $email = '') {
    $query = $this->db->get_where($account_type, array('email' => $email));
    if ($query->num_rows() > 0) {
        $password = $query->row()->password;
        $email_msg = "Your account type is : " . $account_type . "<br />";
        $email_msg .= "Your password is : " . $password . "<br />";

        $email_sub = "Password reset request";
        $email_to = $email;
        $this->do_email($email_msg, $email_sub, $email_to);
        return true;
    } else {
        return false;
    }
}

/*     * *custom email sender*** */

function do_email($msg = NULL, $sub = NULL, $to = NULL, $from = NULL) {

    $config = array();
    $config['useragent'] = "CodeIgniter";
    $config['mailpath'] = "/usr/bin/sendmail"; // or "/usr/sbin/sendmail"
    $config['protocol'] = "smtp";

    $config['smtp_port'] = "25";
    $config['mailtype'] = 'html';
    $config['charset'] = 'utf-8';
    $config['newline'] = "\r\n";
    $config['wordwrap'] = TRUE;

    $this->load->library('email');

    $this->email->initialize($config);

    $system_name = $this->db->get_where('settings', array('type' => 'system_name'))->row()->description;
    if ($from == NULL)
        $from = $this->db->get_where('settings', array('type' => 'system_email'))->row()->description;

    $this->email->from($from, $system_name);
    $this->email->from($from, $system_name);
    $this->email->to($to);
    $this->email->subject($sub);

    $msg = $msg . "<br /><br /><br /><br /><br /><br /><br /><hr /><center><a>&copy; 2017 blablabla</a></center>";
    $this->email->message($msg);

    $this->email->send();

    //echo $this->email->print_debugger();
}

}

}

在视图中，一个login.php：

/*     * *RESET AND SEND PASSWORD TO REQUESTED EMAIL*** */

function reset_password() {
    $account_type = $this->input->post('account_type');
    if ($account_type == "") {
        redirect(base_url(), 'refresh');
    }
    $email = $this->input->post('email');
    $result = $this->email_model->password_reset_email($account_type, $email); //SEND EMAIL ACCOUNT OPENING EMAIL
    if ($result == true) {
        $this->session->set_flashdata('flash_message', get_phrase('password_sent'));
    } else if ($result == false) {
        $this->session->set_flashdata('flash_message', get_phrase('account_not_found'));
    }

    redirect(base_url(), 'refresh');
}
