CodeIgniter урок 14

У тебя ошибка:

 else{echo ("Новость не отредактирована"); }

скобки лишние. 

Попробуй такой код для удаления и редактирования новости:

	public function edit($slug = NULL) {

		$this->data['title'] = 'Редактировать новость';
		$this->data['news_item'] = $this->News_model->getNews($slug);

		if (empty($this->data['news_item'])) {
			show_404();
		}
		
		$this->data['id_news'] = $this->data['news_item']['id'];
		$this->data['title_news'] = $this->data['news_item']['title'];
		$this->data['content_news'] = $this->data['news_item']['text'];
		$this->data['slug_news'] = $this->data['news_item']['slug'];

		if($this->input->post('slug') && $this->input->post('title') && $this->input->post('text')) {

			$id = $this->data['news_item']['id'];
			$slug = $this->input->post('slug');
			$title = $this->input->post('title');
			$text = $this->input->post('text');

			if($this->News_model->updateNews($id, $slug, $title, $text)) {
				$this->data['title'] = 'Успешно обновлено';
				$this->load->view('templates/header', $this->data);
				$this->load->view('news/edited');
				$this->load->view('templates/footer');
			}
		}
		else{
			$this->load->view('templates/header', $this->data);
			$this->load->view('news/edit', $this->data);
			$this->load->view('templates/footer');

	}	}  

	public function delete($slug = NULL) {


		$this->data['news_delete'] = $this->News_model->getNews($slug);

		if(empty($this->data['news_delete'])) {
			show_404();
		}

		$this->data['title'] = "Удалить новость";
		$this->data['result'] = "Ошибка удаления ".$this->data['news_delete']['title'];
