I'm working on a code and need to make an association, where I have to count the amount of voting in a video. The problem is that there are 2 tables of videos and votes . In videos is the videos, and there is the id of the video and the link. In votacoes has the id_video and who voted. I'm using CodeIgniter to query and list the videos:

Controller:

class Promocao extends CI_Controller {
    public function __construct() {
        parent::__construct();
        $this->load->model('miss_model', 'miss');
    }


    public function votacao($id = NULL) {

/* Pega os vídeos */
        $data['videos'] = $this->miss->find_all('id', 'desc');
        $data['titulo'] = 'Votação - TOP CLASS VIP';
        $this->load->view('votacao', $data);

    }
}

View:

<?php if (count($videos)):foreach ($videos as $row):?>
    <div class="col-md-4">    
        <video width="240" height="240" controls>
            <source src="<?php echo base_url('assets/videos/miss/' . $row['video'])?>" type="video/mp4">
            <source src="<?php echo base_url('assets/videos/miss/' . $row['video'])?>" type="video/ogg">
            Your browser does not support the video tag.
        </video>

        <?php echo anchor('promocao/votacao/' . $row['id'], 'VOTAR', 'class="btn btn-success"');?>
    </div>
<?php endforeach;?>
<?php else:?>
    <h1 class="text-center">SEM VÍDEOS</h1>
<?php endif;?>

In view I need to put 30 votes for example, ie display the number of votes cast for each video. The problem is that I do not know how to relate the two tables to the id of the video and id_video of the other table.

Well, to join in CI is like this: within the model that inherits the CI model

public function listaVideos()
{
   return $this->db->select("videos.*, votacoes.voto")
               ->join("votacoes", "votacoes.id_video=videos.id")
               ->get("videos")->result();
}

It's more or less that
a good reference is also the documentation itself: link
