<?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);

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($news['body'])?></p>
<button>Delete</button>
i have tried the following in my controller
and it didint delete it from my database but i also did not get an error! it just redirects me to my succes page.
public function delete($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
id|title|slug|body

Answer 1

i changed my view button to
Delete
and in my controller i made
public function delete($id)
{
$model = new NewsModel();
$model->where('id', (int) $id)->delete();
return view('news/delete');
}
