Question

Basically i’m trying to build a comment system. The user looks at a photo on the site, and then can view all the comments made by other members.

Each comment will be looped out using a foreach (currently working fine), but what I need to do is then run a seperate query for each comment to get the user details of the user who posted it. These details are stored on a seperate database (otherwise i’d just do a join).

My model has this in it so far:

public function get_comment($id)
{
    $db_photos = $this->load->database('photos', TRUE);
    $db_photos->select('id, comment, userid, photoid');
    $db_photos->from('comments');
    $db_photos->where('photoid', $id);

    return $db_photos->get()->result();
}

And here’s the controller:

public function view($id)
    {   

        $data['comment'] = $this->viewphoto_model->get_comment($id);
        if (empty($data['comment'])) { show_404(); }

        $this->load->view('templates/header', $data);
        $this->load->view('viewphoto/viewphoto', $data);
        $this->load->view('templates/footer', $data);
    }

And then the view:

<?php foreach ($comment as $comments): ?>
        <div class="ViewPhoto-CommentsBox">
        <? echo $comments->comment; ?>
        </div>
        <?php endforeach ?>

So basically I need to grab the ‘userid’ value from each comment and then run a query on the ‘users’ database to get the user details for each comment posted.

Any help is most appreciated 🙂

EDIT:

Still not working, here’s latest version.

Controller:

change your controller like this.

 public function view($id)
        {       
              $comment= $this->viewphoto_model->get_comment($id);

              if($comment->num_rows() > 0)
                {
                    foreach ($comment->result() as $r)
                    {
                        $data['reg'][$i]['comment']=$r->comment;
                        $data['reg'][$i]['id']=$r->id;           

                       // Get user details from user table
                        $user_profile=$this->viewphoto_model->get_user_profile_details($r->userid);
                        if($user_profile->num_rows() > 0)
                        {
                            foreach ($user_profile->result() as $row)
                            {
                                // user details whatever you have in your db.
                                $data['reg'][$i]['name']=$row->name;
                                $data['reg'][$i]['gender']=$row->gender;
                                $data['reg'][$i]['phone_no']=$row->phone_no;
                            }
                        }

                        $i++;
                    }
                }
            $this->load->view('templates/header', $data);
            $this->load->view('viewphoto/viewphoto', $data);
            $this->load->view('templates/footer', $data);
        }

View file: you can use details like below.

<?php if(isset($reg)) { foreach ($reg as $comments): ?>
        <div class="ViewPhoto-CommentsBox">
        <? echo $comments['comment']; ?>
         <? echo $comments['name']; // user detail ?>
        </div>
        <?php endforeach ?>
        <? } ?>
