you're not passing $data view. controller should this:
public function show_news() { $this->load->model('user'); $data = []; $data['news'] = $this->user->get_news(); $this->load->view('news', $data); } your view should checking if $news false, because you'll have issues foreach if loop on value false. model should returning result_array not result, foreach cam't loop on objects..
public function get_news() { $q = $this->db->get('news'); return($q->num_rows() > 0) ? $q->result_array() : false; } your view should this:
<?php if($news !== false) { foreach($news $row) { echo "<li>{$row['title']}</li>"; echo "<li>{$row['date']}</li>"; } } else { echo "no news see here!"; } ?> your title doesn't link error in post, that's solution 1 in title.
