Чтобы получить забыли пароль

Question

В приведенном ниже коде я использовал код codeigniter. Я вводил имя пользователя и пароль в db.but. Я хочу получить забытый пароль. Я попытался, но у меня появились следующие ошибки.

Контроллер:

<?php 

class Login extends CI_Controller { 

    function index() 
    { 
     $data['main_content'] = 'login_form';

    } 

    function validate_credentials() 
    {  
     $this->load->model('membership_model');

     if($query) // if the user's credentials validated...

Ну прежде всего вам потребуется функция в контроллере, чтобы привести пользователя к забыли пользовательская страница.

public function forgot_pass(){ 
$this->load->view('forgot_pass_view'); 
} 

Тогда вам, вероятно, потребуется задать по крайней мере адрес электронной почты в представлении. Создайте еще одну функцию, чтобы проверить адрес электронной почты в контроллере, и если он совпадает с отправкой почты с новым временным паролем.

public function check_email(){ 
    $this->load->helper(array('form', 'url')); 
    $this->load->library('form_validation'); 
    $this->form_validation->set_rules('email', 'email_check', 'callback_email_check'); 
    if ($this->form_validation->run() == FALSE){ 
    //throw error 
    } else { 
    //send email 
    } 
} 
public function email_check(){ 
    //use this function to check if the email exists and return false if it is not the DB 
}
