Sorry! Cannot seem to find the page you were looking for.

PHP Code:

public function check(){

        $validation = $this->validate([
            'email' => [
                'rules'  => 'required|valid_email|is_not_unique[users.email]',
                'errors' => [
                    'required' => 'Email is required.',
                    'valid_email' => 'Please check the Email field. It does not appear to be valid.',
                    'is_not_unique' => 'Email not registered in our server.',
                ],
            ],
            'password' => [
                'rules'  => 'required|min_length[5]|max_length[20]',
                'errors' => [
                    'required' => 'Password is required.',
                    'min_length' => 'Password must have atleast 5 characters in length.',
                    'max_length' => 'Password must not have characters more thant 20 in length.',
                ],
            ],
        ]);

        if(!$validation){
            return  redirect()->to('auth/login')->with('validation', $this->validator)->withInput();
        }else{
            $email = $this->request->getPost('email');
            $password = $this->request->getPost('password');
            $userModel = new UserModel();
            $user_info = $userModel->where('email', $email)->first();

            $check_password = Hash::check($password, $user_info['password']);
            if( !$check_password ){
                return  redirect()->to('auth/login')->with('fail', 'Incorect password.')->withInput();
            }else{
                $session_data = ['user' => $user_info];
                session()->set('LoggedUser', $session_data);
                $data['xin_chao']='abc';
              
                return  redirect()->to('auth/home');

            }
        }
    } 


thank you for reading

Hi. Check if you have correctly set destination route auth/home in app/Config/Routes.php. It could be something like this:

PHP Code:

$routes->get('auth/home', 'Auth::home'); 


You could also check if you have correct variables $baseURL and $indexPage in app/Config/App (or in .env file if you are using it), because redirect()->to() is based on these values.

---

If it does not work, then try only redirection on a fresh CodeIgniter's installation.

app/Config/App.php

PHP Code:

// ...
// change these variables
    public string $baseURL = 'http://localhost:8080/'; // change if you are not using "php spark serve" or if it started on a different port
    public string $indexPage = ''; // removing index.php proved to me in all cases
// ... 


app/Config/Routes.php

PHP Code:

// ...
// add these routes
$routes->get('from', 'Home::from');
$routes->get('to', 'Home::to');
//... 


app/Controller/Home.php

PHP Code:

// ...
// add these methods
    public function from()
    {
        return redirect()->to('to');
    }
    public function to()
    {
        echo 'Successfully redirected to home/to.';
    }
// ... 


Access this URL in a web browser (based on $baseURL): http://localhost:8080/from and watch if it is working. If it will work, then the problem is somewhere in your code or settings.

if you are using validation,  it is pretty much sure you want to g back to the same page with the validation error in this case instead of using 

PHP Code:

return redirect()->to() 


  you can use

PHP Code:

redirect()->back() 


, although the way you have done it should work, just check your routes in the console 

Code:

php spark routes

thjs code under line  working  good

header("Location:".base_url('login'));

thjs code under line  working  good

header("Location:".base_url('login'));

your code won't work until you use die or exit after header function.

Learning Codeigniter 

thjs code under line  working  good

header("Location:".base_url('login'));

It's  OK
//return redirect()->to('login');
header("Location:".base_url('login'));//BYOOS_tag
exit();
