Hi, I am new to CI and I am having trouble wrapping my head around some simple things. Right now all I am trying to do is just put the number of comments a blog post has under the post but for the life of me I cant figure out how to. I understand how you would do it with just PHP but obviously the point is to have CI make life easier so I am trying to use it. Any help would be much appreciated. Thanks

For people not familiar with the blog video tutorial here is the controller code:

Code:
function Blog(){

        parent::Controller();

        $this->load->helper('url');

        $this->load->helper('form');

    }

    function index(){

        $data['title'] = 'Mike\'s Blog';

        $data['heading'] = 'Mike\'s Blog Heading';

        $data['query'] = $this->db->get('entries');

        $this->load->view('blog_view', $data);

    }

    function comments(){

        $data['title'] = 'Mike\'s Blog';

        $data['heading'] = 'Mike\'s Comment Heading';

        $this->db->where('entry_id', $this->uri->segment(3));

        $data['query'] = $this->db->get('comments');

        $this->load->view('comment_view', $data);

    }

    function comment_insert(){

        $this->db->insert('comments', $_POST);

        redirect('blog/comments/' . $_POST['entry_id']);

    }

}

?&gt;

and the blog view code:

Code:
&lt;html&gt;

    &lt;head&gt;

        &lt;title&gt;&lt;?php echo $title; ?&gt;&lt;/title&gt;

    &lt;/head&gt;

    &lt;body&gt;

    <h1>&lt;?php echo $heading; ?&gt;</h1>

        &lt;?php foreach($query->result() as $row): ?&gt;

            <h3>&lt;?php echo $row->title; ?&gt;</h3>

            <p>&lt;?php echo $row->body; ?&gt;</p>

            <p>&lt;?php echo anchor('blog/comments/' . $row->id, 'Comments'); ?&gt;</p>

            <hr>

        &lt;?php endforeach; ?&gt;

    &lt;/body&gt;

&lt;/html&gt;
