Codeigniter blog: display post title in comments table - php

Question

I am working on a blog application in Codeigniter 3.1.8 and Bootstrap 4.
There is a posts table and a comments table in the database. I have displayed all the comments in a Bootstrap 4 table. I want to display the title of the post each comment belongs to, instead of the post's id:
My Comments controller:
class Comments extends CI_Controller {
public function __construct()
{
parent::__construct();
$this->load->model('Static_model');
$this->load->model('Posts_model');
$this->load->model('Categories_model');
$this->load->model('Comments_model');
}
public function index() {
$data = $this->Static_model->get_static_data();
$data['categories'] = $this->Categories_model->get_categories();
$data['number_of_categories'] = $this->Categories_model->get_num_rows();
$data['posts'] = $this->Posts_model->get_all_posts();
$data['number_of_posts'] = $this->Posts_model->get_num_rows();
$data['comments'] = $this->Comments_model->get_all_comments();
$this->load->view('partials/header', $data);
$this->load->view('dashboard/comments');
$this->load->view('partials/footer');
}
}
In the Comments_model model I have:
public function get_all_comments(){
$this->db->select('comments.*');
$this->db->order_by('comments.id', 'DESC');
//$this->db->limit($limit, $offset);
$this->db->join('posts', 'posts.id = comments.post_id');
$query = $this->db->get('comments');
return $query->result();
}
In the view:
<tbody>
<?php foreach ($comments as $index => $comment): ?>
<tr id="<?php echo $comment->id; ?>">
<td><?php echo $index + 1; ?></td>
<td class="w-25"><?php echo $comment->comment; ?></td>
<td><?php echo $comment->name; ?></td>
<td><?php echo $posts['title']; ?></td>
<td><?php echo nice_date($comment->created_at, 'D, M d, Y'); ?></td>
<td>Aproved</td>
<td></td>
</tr>
<?php endforeach ?>
</tbody>
While <?php echo $posts->id; ?> displays the posts id, which i do not need in the view, the line results in an
Message: Undefined index: title error.
What is missing?

Hope this will help you :
get_all_comments method should be like this : add posts.title in select also
public function get_all_comments()
{
$this->db->select('comments.*,posts.title as post_title');
$this->db->order_by('comments.id', 'DESC');
//$this->db->limit($limit, $offset);
$this->db->join('posts', 'posts.id = comments.post_id');
$query = $this->db->get('comments');
return $query->result();
}
Replace it
<td><?php echo $posts['title']; ?></td>
with
<td><?php echo $comment->post_title; ?></td>
