protected $table = 'news';
protected $allowedFields = ['title', 'slug', 'body'];
public function getNews($slug = false)
{
if ($slug === false) {
return $this->findAll();
}
return $this->asArray()
->where(['slug' => $slug])
->first();
}
}
here is Controller(News.php)
<?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(),
'title' => 'News archive',
];
echo view('templates/header', $data);
echo view('news/overview', $data);
echo view('templates/footer', $data);
}
public function view($slug = null)
{
$model = new NewsModel();
$data['news'] = $model->getNews($slug);
if (empty($data['news'])) {
throw new \CodeIgniter\Exceptions\PageNotFoundException('Cannot find the news item: ' . $slug);
}
$data['title'] = $data['news']['title'];
echo view('templates/header', $data);
echo view('news/view', $data);
echo view('templates/footer', $data);
}
public function create()
{
$model = new NewsModel();
if ($this->request->getMethod() === 'post' && $this->validate([
'title' => 'required|min_length[3]|max_length[255]',
'body' => 'required',
])) {
$model->save([
'title' => $this->request->getPost('title'),
'slug' => url_title($this->request->getPost('title'), '-', true),
'body' => $this->request->getPost('body'),
]);
echo view('news/success');
} else {
echo view('templates/header', ['title' => 'Create a news item']);
echo view('news/create');
echo view('templates/footer');

View(view.php)
<h2><?=esc($news['title'])?></h2>
<p><?=esc($news['body'])?></p>
<button><a href="/news/delete" class="btn btn-danger">Delete</a></button>
i have tried the following in my controller
and it didint delete it from my database but i also did not get an error! it just redirects me to my succes page.
public function delete($id = null)
{
$model = new NewsModel();
$model->delete([
$model->where('id', $id)->delete(),
]);
return view('news/delete');
}
i have also tried this
public function delete()
{
$model = new NewsModel();
if ($this->request->getMethod() === 'post') {
$model->delete([
'title' => $this->request->getPost('title'),
'body' => $this->request->getPost('body'),
]);
echo view('news/delete');
}
DB set up
DB NAME= toets
TABLE= news

i changed my view button to
<a href="<?= '/news/delete/' . esc($news['id']) ?>">Delete</a>
and in my controller i made
public function delete($id)
{
$model = new NewsModel();
$model->where('id', (int) $id)->delete();
return view('news/delete');
