News section

i can only see what you have posted but index method is missing a curly brace, above that it looks un complete could  be:

Code:

public function index()
{
       

     $model = new NewsModel(); 
     $data['news'] = $model->getNews($slug);
     $data = [
         'news'  => $model->getNews(),
         'title' => 'News archive', // there is no other item so "," not needed


     ];


} //end of method

my code, this code from CodeIgniter4 User Guide

PHP Code:

<?php namespace App\Controllers;

use App\Models\NewsModel;
use CodeIgniter\Controller;

class News extends Controller
{
    public function index()
    {
        $model = new NewsModel();

        $data['news'] = $model->getNews();
    }

    public function view($slug = null)
    {
        $model = new NewsModel();

        $data['news'] = $model->getNews($slug);
    }
}

public function index()
{
    $model = new NewsModel();

    $data = [
        'news'  => $model->getNews(),
        'title' => 'News archive',
    ];

    echo view('templates/header', $data);
    echo view('news/overview', $data);
    echo view('templates/footer', $data);
} 


now you are confusing me ; two methods both called Index ? you can't have that
