need some help

I am working on a forum script. it works when i do it mostly in the view but i really want to do is make it smarty friendly.

i can not for the life of me figure out how to get it to pass the data right.
this is for my category section

Code:

$rows       = $this->db->query("SELECT * FROM forum_category");


    $reputation = array();
    foreach ($rows->result_array() as $row)
    {

      $rep = array();
      $rep['name'] = $row['name'];
      $rep['id'] = $row['id'];

      // Add this array to the other one
      $reputation[] = $rep;



    }

    return $reputation;

this is for the topics of the forums

Code:

$sql = $this->db->query("SELECT * FROM forum_topic WHERE cat_id='$slug'");
    $war = array();
    foreach ($sql->result_array() as $rows)
    {

      $reps = array();
      $reps['subject'] = $rows['subject'];
      $reps['id'] = $rows['id'];
      $reps['desc'] = $rows['description'];
      $wars[] = $reps;

      
    }
    return $wars;

how would i go about getting this to work with smarty and codeigniter.
this is my controller for the forum.

Code:

$data['result'] = $this->forum_model->getthreads();
      $war = array();
      foreach ($data['result'] as $rows) {
        $war[] = $this->forum_model->showtopic($rows['id']);
      }

      $data['topic'] = $war;

this is what my original code looks like on the view

Code:

public function showthreads()
  {
      $query=$this->db->query("SELECT * FROM forum_category");
      foreach($query->result_array() as $row):
      ?>
      <table class='table forum table-striped'>
            <thead>
      <tr>
        <th class='cell-stat'></th>
        <th>
          <h3><?=$row['name'];?></h3>
        </th>
        <th class='cell-stat text-center hidden-xs hidden-sm'>Topics</th>
        <th class='cell-stat text-center hidden-xs hidden-sm'>Posts</th>
        <th class='cell-stat-2x hidden-xs hidden-sm'>Last Post</th>
      </tr>
    </thead>
    <tbody>
    <?
     $query=$this->db->query("SELECT * FROM forum_topic WHERE cat_id=$row[id]");
    foreach($query->result() as $topic):
    $total=$this->db->query("SELECT * FROM forum_thread WHERE thr_id='$topic->id'");
    $thread=$total->row();
    $totals=$this->db->query("SELECT * FROM forum_posts WHERE thr_id='$topic->id'");
    $post=$totals->row();
    if($total->num_rows() == 0)
    {
        $threads="<td class='hidden-xs hidden-sm'>by <a href='#'>jane doe</a><br><small><i class='fa fa-clock-o'></i> 3 months ago</small></td>";
    }else
    {
        $threads="<td class='hidden-xs hidden-sm'>by <a href='".base_url()."profile/$thread->poster'>$thread->poster</a><br><small><i class='fa fa-clock-o'></i> ".date("M d, Y g:i",$thread->date)."</small></td>";
    }
    ?>
     <tr>
        <td class='text-center'><i class='fa fa-question fa-2x text-primary'></i></td>
        <td>
          <h4><a href='<?=base_url();?>forum/<?=$topic->id;?>'><?=$topic->subject;?></a><br><small><?=$topic->description;?></small></h4>
        </td>
        <td class='text-center hidden-xs hidden-sm'><a href='#'><?=$total->num_rows();?></a></td>
        <td class='text-center hidden-xs hidden-sm'><a href='#'><?=$totals->num_rows();?></a></td>
        <?=$threads;?>
      </tr>
    <? endforeach;?>
    </tbody>
    </table>
        <?
      
      endforeach;
      }

Code:

Array ( [0] => Array ( [id] => 2 [subject] => Updates [description] => Latest Updates [cat_id] => 1 ) ) 1

Code:

$data = array(
        'user'   =>$this->user->get_user_details(),
        'results'=>$this->forum_model->getthreads(),
        'title'  =>$this->config->item('sitename'));
      $data['news'] = $this->news_model->get_news();
      foreach($data['results'] as $row)
      {
          $war[]=$row['id'];
      
      }
      foreach($war as $wars)
      {
          var_dump($wars);
      $data['forum'] = $this->forum_model->showthreads($wars);
      }

Code:

public function showthreads($slug=false)
  {
    $query = $this->db->query("SELECT * FROM forum_topic WHERE id='$slug'");
    $rows  = array();
    foreach ($query->result_array() as $row)
    {
      $rows[] = $row;
    }
    return $rows;
  }

i got this now

Code:

Array ( [0] => Array ( [0] => Array ( [id] => 1 [subject] => Lastest News [description] => Latest News [cat_id] => 1 ) ) [1] => Array ( [0] => Array ( [id] => 2 [subject] => Updates [description] => Latest Updates [cat_id] => 1 ) ) ) 1
