Need help with my delete button

You can use the ID of the news item. I am assuming the ID field here is simply "id".

PHP Code:

// your view


<h2><?= esc($news['title']) ?></h2>
<p><?= esc($news['body']) ?></p>

<a href="<?= '/news/delete/' . esc($news['id']) ?>">Delete</a>


// in your controller's delete method
public function delete($id)
{
    $model = new NewsModel();
    $model->where('id', (int) $id)->delete();

    return view('news/delete');
} 


A little comment if you don't mind. I'm also assuming this delete button is only within the reach of the admins. If you release this to unprivileged users, all posts are at risk to be deleted.
