Codeigniter返回db结果错误

Question

你好朋友我有一个codeigniter问题并使用foreach返回db结果我有这个：

function get_test($id)
{
    $this -> db -> select('name, date, title, description');
    $this -> db -> from('table1');
    $this -> db -> join('table2', 'table1.id = table2.id');
    $this -> db -> where('table1.id', $id);

    $query = $this -> db -> get();
    return $query->row_array();   

      }

控制器

function index()
{
   $session_data = $this->session->userdata('logged_in');
    $data['id'] = $session_data['id'];
    //SQL
    $data['results'] = $this->model1_model->get_test($data['id']);

    $this->load->view('base/header');
    $this->load->view('incidencia/index',$data);
}

视图

<?php foreach($results as $i): ?>
  <div class="panel panel-default">
    <div class="panel-heading">
      <div class="row">
        <div class="col-md-2">
          <p><b>Id incidencia:</b> <?php echo $i['id'];?></p>
        </div>

        <div class="col-md-2">
          <p><b>Usuario:</b> <?php echo $i['name']; ?></p>
        </div>
      </div>
     </div>
  <div class="panel-body">
    <div class="col-md-10">
      <p><b></b> <?php echo $i['title]; ?><p>
      <p><b></b> <?php echo $i['description']; ?></p>
    </div>
    <div class="col-md-2">
    </div>
</div>
</div>
<?php endforeach; ?>

但我有这个错误：消息：非法字符串偏移'名称
