问题
Good day! I'm trying to make a forgot password function in the CodeIgniter framework but I'm getting 2 errors when i try to send the e-mail.
Some database info (I'm using phpMyAdmin):
Db name: kadokado
Db table name: users
Db email column: email
Db password column: wachtwoord
My controller file (Auth.php) :
<?php
class Auth extends CI_Controller{
public function forgot()
{
$this->form_validation->set_rules('email', 'Email', 'required|valid_email');
if($this->form_validation->run() == FALSE) {
$this->load->view('templates/header');
$this->load->view('forgot');
$this->load->view('templates/footer');
}else{
$email = $this->input->post('email');
$clean = $this->security->xss_clean($email);
$userInfo = $this->user_model->getUserInfoByEmail($clean);
if(!$userInfo){
$this->session->set_flashdata('flash_message', 'We hebben dit email adres niet kunnen vinden');
redirect(site_url().'auth/login');
}
if($userInfo->status != $this->status[1]){ //if status is not approved
$this->session->set_flashdata('flash_message', 'Your account is not in approved status');
redirect(site_url().'auth/login');
}
//build token
$token = $this->user_model->insertToken($userInfo->id);
$qstring = $this->base64url_encode($token);
$url = site_url() . 'auth/reset_password/token/' . $qstring;
$link = '<a href="' . $url . '">' . $url . '</a>';
$message = '';
$message .= '<strong>A password reset has been requested for this email account</strong><br>';
$message .= '<strong>Please click:</strong> ' . $link;
echo $message; //send this through mail
exit;
}
}
public function reset_password()
{
$token = $this->base64url_decode($this->uri->segment(4));
$cleanToken = $this->security->xss_clean($token);
$user_info = $this->user_model->isTokenValid($cleanToken); //either false or array();
if(!$user_info){
$this->session->set_flashdata('flash_message', 'Token is invalid or expired');
redirect(site_url().'auth/login');
}
$data = array(
'voornaam'=> $user_info->voornaam,
'email'=>$user_info->email,
'token'=>base64_encode($token)
);
$this->form_validation->set_rules('wachtwoord', 'Wachtwoord', 'required|min_length[5]');
$this->form_validation->set_rules('passconf', 'Password Confirmation', 'required|matches[wachtwoord]');
if ($this->form_validation->run() == FALSE) {
$this->load->view('templates/header');
$this->load->view('reset_password', $data);
$this->load->view('templates/footer');
}else{
$this->load->library('wachtwoord');
$post = $this->input->post(NULL, TRUE);
$cleanPost = $this->security->xss_clean($post);
$hashed = $this->password->create_hash($cleanPost['wachtwoord']);
$cleanPost['wachtwoord'] = $hashed;
$cleanPost['user_id'] = $user_info->id;
unset($cleanPost['passconf']);
if(!$this->user_model->updatePassword($cleanPost)){
$this->session->set_flashdata('flash_message', 'Er is iets foutgegaan');
}else{
$this->session->set_flashdata('flash_message', 'Uw wachtwoord is geupdate, u kunt nu inloggen');
}
redirect(site_url().'auth/login');
}
}
}
My model file (User_Model.php) :
<?php
class user_model extends CI_model {
public function getUserInfoByEmail($email)
{
$q = $this->db->get_where('users', array('email' => $email), 1);
if($this->db->affected_rows() > 0){
$row = $q->row();
return $row;
}else{
error_log('no user found getUserInfo('.$email.')');
return false;
}
}
public function getUserInfo($user_id)
{
$q = $this->db->get_where('users', array('user_id' => $user_id), 1);
if($this->db->affected_rows() > 0){
$row = $q->row();
return $row;
}else{
error_log('no user found getUserInfo('.$user_id.')');
return false;
}
}
public function insertToken($user_id)
{
$token = substr(sha1(rand()), 0, 30);
$date = date('Y-m-d');
$string = array(
'token'=> $token,
'user_id'=>$user_id,
'created'=>$date
);
$query = $this->db->insert_string('tokens',$string);
$this->db->query($query);
return $token . $user_id;
}
public function isTokenValid($token)
{
$tkn = substr($token,0,30);
$uid = substr($token,30);
$q = $this->db->get_where('tokens', array(
'tokens.token' => $tkn,
'tokens.user_id' => $uid), 1);
if($this->db->affected_rows() > 0){
$row = $q->row();
$created = $row->created;
$createdTS = strtotime($created);
$today = date('Y-m-d');
$todayTS = strtotime($today);
if($createdTS != $todayTS){
return false;
}
$user_info = $this->getUserInfo($row->user_id);
return $user_info;
}else{
return false;
}
}
}
?>
My view file (reset_password.php) :
<div class="col-lg-4 col-lg-offset-4">
<h2>Reset your password</h2>
<h5>Hello <span><?php echo $firstName; ?></span>, Voer uw wachtwoord 2x in aub</h5>
<?php
$fattr = array('class' => 'form-signin');
echo form_open(site_url().'auth/reset_password/token/'.$token, $fattr); ?>
<div class="form-group">
<?php echo form_password(array('name'=>'wachtwoord', 'id'=> 'wachtwoord', 'placeholder'=>'Wachtwoord', 'class'=>'form-control', 'value' => set_value('wachtwoord'))); ?>
<?php echo form_error('password') ?>
</div>
<div class="form-group">
<?php echo form_password(array('name'=>'passconf', 'id'=> 'passconf', 'placeholder'=>'Confirm Password', 'class'=>'form-control', 'value'=> set_value('passconf'))); ?>
<?php echo form_error('passconf') ?>
</div>
<?php echo form_hidden('user_id', $user_id);?>
<?php echo form_submit(array('value'=>'Reset Password', 'class'=>'btn btn-lg btn-primary btn-block')); ?>
<?php echo form_close(); ?>
</div>
And these are the errors I'm getting:
A PHP Error was encountered
Severity: Notice
Message: Undefined property: Auth::$user_model
Filename: controllers/Auth.php
Line Number: 123

2nd error:

I have absolutely no clue what I'm doing wrong and I hope someone can help me. Thanks!
回答1:
Load user model in auth controller. You can load it in constructor or in the function.
class Auth extends CI_Controller{
function __construct(){
parent::__construct();
$this->load->model('user_model'); // load user model
}
public function forgot(){
// your code
}
In Function
class Auth extends CI_Controller{
public function forgot(){
$this->load->model('user_model'); // load user model
// your code
}
Not tested
回答2:
You need to make sure that the user_model class is loaded from the controller. Like so:
class Auth extends CI_Controller {
function __construct() {
$this->load->model('user_model');
}
}
And be sure that you have the spelling/capitalization correct in the model class.
class User_Model extends CI_Model {
// rest of code
}

@frodo again.
First Error : in your controller code, you need to initialize model first than only you can use the model property.
public function forgot(){
// Changes required
$this->load->model('user_model');
$userInfo = $this->user_model->getUserInfoByEmail($clean);
}
Second Error :
if($userInfo->status != $this->status[1]){
$this->session->set_flashdata('flash_message', 'Your account is not in approved status');
redirect(site_url().'auth/login');
}
How you get the value of $this->status[1] variable. You can simply use if($userInfo->status != true).
Please change this code and let me know if you have any error.
