Loading helper before controller - Cyto5 - 08-27-2020

What is a good way to load a helper before the controllers run. I am trying to use a function in a helper file inside my controller __construct() function and I am autoloading them in the basecontroller right now but they are not available when __construct() is ran. What would be the best method of making sure the helper is available from within a controllers __construct()?

Thanks.

Can you show some code?

I want this but my Perm class uses a function in an auto-loaded helper file so this doesn't work.

PHP Code:
class AdminBaseController extends \App\Controllers\BaseController
{
    public function _defaultAdminPerms()
    {
        Auth::reqLogin();
        Perm::hasOrRedirect('IS_ADMIN', '/dashboard');
    }
}


class Courses extends \App\Controllers\Admin\AdminBaseController
{
    public function __construct()
    {
        parent::__construct();
        $this->_defaultAdminPerms();
    }
} 

However this works but it requires calling the function at the start every every public controller

PHP Code:
class AdminBaseController extends \App\Controllers\BaseController
{
    public function _defaultAdminPerms()
    {
        Auth::reqLogin();
        Perm::hasOrRedirect('IS_ADMIN', '/dashboard');
    }
}


class Courses extends \App\Controllers\Admin\AdminBaseController
{
    public function __construct()
    {
        parent::__construct();
    }
    
    public function f1()
    {
        $this->_defaultAdminPerms();
        ...
    }
    
    public function f2()
    {
        $this->_defaultAdminPerms();
        ...
    }
    
    public function f3()
    {
        $this->_defaultAdminPerms();
        ...
    }
}

Don't know exactly why this is (haven't looked in the code itself), but you can use an initController method instead of __construct to do what you want.

PHP Code:
public function initController(\CodeIgniter\HTTP\RequestInterface $request, \CodeIgniter\HTTP\ResponseInterface $response, \Psr\Log\LoggerInterface $logger)
{
    // Do Not Edit This Line
    parent::initController($request, $response, $logger);

    $this->_defaultAdminPerms();
}

Thank you I think that is working now I actually have it inside a custom admin adminbasecontroller that extends the default basecontroller and it looks to be working from that.

PHP Code:
class AdminBaseController extends \App\Controllers\BaseController
{
    public function __construct()
    {
        parent::__construct();
    }
    
    public function initController(\CodeIgniter\HTTP\RequestInterface $request, \CodeIgniter\HTTP\ResponseInterface $response, \Psr\Log\LoggerInterface $logger)
    {
        parent::initController($request, $response, $logger);
        $this->_defaultAdminPerms();
    }
    
    public function _defaultAdminPerms()
    {
        Auth::reqLogin();
        Perm::hasOrRedirect('IS_ADMIN', '/dashboard');
    }

}

PHP Code:
public function __construct()
    {
        parent::__construct();
    } 

This code are unnecessary, in case you are only doing just that.

I have other code inside that function but good tip if anyone else does that and has nothing else. Thanks!

You could also place it in common.php

RE: Loading helper before controller - someone - 10-01-2020

Is this a good way to control before and after actions in CI4?

PHP Code:
   private function beforeRequest()
    {
        echo "Before";
    }

    private function afterRequest()
    {
        echo "After";
    } 

And my initController looks like that;

PHP Code:
    public function initController(\CodeIgniter\HTTP\RequestInterface $request, \CodeIgniter\HTTP\ResponseInterface $response, \Psr\Log\LoggerInterface $logger)
    {
        
                $this->beforeRequest();
        // Do Not Edit This Line
        parent::initController($request, $response, $logger);

        //--------------------------------------------------------------------
        // Preload any models, libraries, etc, here.
        //--------------------------------------------------------------------
        // E.g.:
                // $this->session = \Config\Services::session();
                $this->afterRequest();    
         }

I think what you want there are controller filters.
