load() method doesn't work

Thank you very much ! I was looking in stackoverflow the whole time but i forgot that i was starting with CI 4 and not CI 3 and that the posts are outdated.

Now i did it this way to save some time.

Controller/Home.php

PHP Code:

<?php namespace App\Controllers;


class Home extends BaseController
{

    public function index()
    {
        $headerData = [
            'tabTitle' => 'Online Shop',
            'tabHome' => 'active'
        ];

        echo $this->viewTemplate('home.php', $headerData);
    }

    //--------------------------------------------------------------------

} 


Controller/BaseController

PHP Code:

public function viewTemplate($viewName, $headerData = [], $footerData = [], $viewData = [])
    {
        echo view('header.php', $headerData);
        echo view($viewName, $viewData);
        echo view('footer.php', $footerData);
    } 


Now it works great.
