how to data in basecontroller.php pass to footer.php view codeigniter 4

1. BaseController.php

PHP Code:

<?php
namespace App\Controllers;
use CodeIgniter\Controller;
use CodeIgniter\HTTP\CLIRequest;
use CodeIgniter\HTTP\IncomingRequest;
use CodeIgniter\HTTP\RequestInterface;
use CodeIgniter\HTTP\ResponseInterface;
use Psr\Log\LoggerInterface;
use App\Models\HeaderModel;

class BaseController extends Controller{
  
    protected $data=array();
    protected $session;
    protected $option ='';
    public function initController(RequestInterface $request, ResponseInterface $response, LoggerInterface $logger){
        parent::initController($request, $response, $logger);

        $this->db = \Config\Database::connect();
        $this->session = \Config\Services::session();

        $mSite= new HeaderModel();
        $this->option = $mSite->site_option_bottom();
        $this->data['site_name']        = $this->option->site_name;
    }

    
} 


2.footer.php

PHP Code:

<?php echo $this->site_name; ?>

NOTE FOR SOMEONE NEED

i only write demo, if you do your project, you can write  method function to show

1. in BaseController.php 

PHP Code:

<?php
namespace App\Controllers;
use CodeIgniter\Controller;
use CodeIgniter\HTTP\CLIRequest;
use CodeIgniter\HTTP\IncomingRequest;
use CodeIgniter\HTTP\RequestInterface;
use CodeIgniter\HTTP\ResponseInterface;
use Psr\Log\LoggerInterface;
use App\Models\HeaderModel;

class BaseController extends Controller{
  
    protected $data;
    protected $session;

    public function initController(RequestInterface $request, ResponseInterface $response, LoggerInterface $logger){
        parent::initController($request, $response, $logger);

        $this->data = \Config\Database::connect();
        $this->session = \Config\Services::session();

        $mSite = new HeaderModel();
        $data['test']= $mSite->site_option_bottom();
     //path view footer.php in your project
        return view('Site\footer',$data);
    }

    
} 


in footer.php we show this

PHP Code:

<?php

print_r($test); 
?>

PHP Code:

return view(”template", $this->data);
// Send param in controller view

#ozornick ,no, I mean without controller but still showing data in the footer.php, in codeigniter 3 can do this, ci4 cant do this

In what situation is the template called without a controller?
If this is some private information output, it must be passed to the method.
Do you have a working use case?

in codeigniter 3, i only write code in  my_controller

view footer.php do like


$demo =$this->option ->myfunction();

echo $demo->site_name

Hmm. In CI 3 $this is "more global" as I recall.
For your last example, the function should return something (object).

PHP Code:

// in my_function(), example
return $this; 


I can’t guess anymore, expect others or try it yourself
