Redirect - oliver - 12-06-2018
Hi,
I have created a BaseController extending CI Controller :
Code:
<?php namespace App\Controllers;
class BaseController extends \CodeIgniter\Controller
{
protected $env_data;
protected $env_user;
function __construct()
{
$this::init();
}
function init() {
$this->env_data = ['init'=>'yes'];
$this->env_user = [];
if(empty($this->env_user)) {
return redirect()->to('/login');
}
}
}Code:
<?php namespace App\Controllers;
class Home2 extends BaseController
{
public function __construct()
{
parent::init();
}
public function index()
{
print_r($this->env_data);
//return redirect()->to('/login');
return view('welcome_message', $this->env_data);
}
}Can someone confirm this is the expected result?
Why is redirection not working in BaseController?
Thanks in advance!
RE: Redirect - kilishan - 12-06-2018
The redirect method returns a RedirectResponse class in CI4, which you must return from your methods. In Home2 it's doing parent::init(), but not returning the RedirectResponse if it is returned.
A second issue you'll run into, though, is that redirects cannot be returned from class constructors now, since we are using a class. You should instead look into using Controller Filters for those type of situations.

Hi,
Thanks for your answer, Kilishan.
I've read the guide concerning filters : seems to be a real improvement in CI4!
But I still can't get my redirect working.
I created application/Filters/AuthFilter.php :
Code:
<?php namespace App\Filters;
use Config\Services;
use CodeIgniter\HTTP\RequestInterface;
use CodeIgniter\HTTP\ResponseInterface;
use CodeIgniter\Filters\FilterInterface;
class AuthFilter implements FilterInterface
{
public function before(RequestInterface $request)
{
echo "filtered";
return redirect('login');
}
public function after(RequestInterface $request, ResponseInterface $response)
{
}
}Then I changed Config/Filters:
Code:
<?php namespace Config;
use CodeIgniter\Config\BaseConfig;
class Filters extends BaseConfig
{
public $aliases = [
'csrf' => \App\Filters\CSRF::class,
'toolbar' => \App\Filters\DebugToolbar::class,
'honeypot' => \App\Filters\Honeypot::class,
'authfilter' => \App\Filters\AuthFilter::class
];
public $globals = [
'before' => [
'authfilter' => ['except'=>['login']]
],
'after' => [
'toolbar'
],
];
public $methods = [];
public $filters = [];
}But when I try to reach Home2::index, only "filtered" is displayed, no redirection takes place :
Code:
<?php namespace App\Controllers;
class Home2 extends BaseController
{
public function __construct()
{
parent::init();
}
public function index()
{
return view('welcome_message', $this->env_data);
}
}Code:
<?php namespace App\Controllers;
class BaseController extends \CodeIgniter\Controller
{
protected $env_data;
protected $env_user;
function __construct()
{
$this::init();
}
function init() {
helper('html', 'url');
$this->env_data = ['init'=>'yes'];
$this->env_user = [];
}

I have learned a lot by looking at Lonnie's sample code like his Myth Auth etc;
You can find them here.

In the documentation it only mentions that it redirects a response, but doesn't state clearly how you need to handle that response.
