错误加入codeigniter

Question

我的加入不起作用！我有这个错误：

PHP Fatal error:  Call to a member function ris_array() on a non-object in
/Applications/MAMP/htdocs/****/application/views/exam/add_view.php on line 90.

在添加视图中：

<table border="0">
  <tr>    
    <th>ID_patient</th>    
    <th>ID_visit</th>
  </tr>

  <?php
    foreach ($query->ris_array() as $row){  
      echo $row['id_pat'];  
      echo $row['id_visit'];  
    }
  ?>
</table>

加入（表访问和患者（id_visit join id_pat））控制器：

public function join($id_pat){
  $this->load->model('visit_model');
  $data['info'] = $this->mods->joins();
  $this->load->view('add_view', $data);
}

在访问模型中：

function joins(){
  $this->db->select('*');
  $this->db->from('patient');
  $this->db->join('visit', 'visit.id_visit = patient.id_pat');
  $query = $this->db->get();
  return $query->ris_array();
}

Answer 1

在你的模型中试试这个：

function joins()
{
    $this->db->select('*');
    $this->db->from('patient');
    $this->db->join('visit', 'visit.id_visit = patient.id_pat');
    $query = $this->db->get();
    return $query;
}

在您的控制器中：

public function join($id_pat)
{
    $this->load->model('visit_model');
    $data['visits'] = $this->visit_model->joins();
    $this->load->view('add_view', $data);
}

那么在你看来：

<table border="0">
<tr>    

      <th>ID_patient</th>    

      <th>ID_visit</th>
</tr>
<?php foreach ($query as $row) : ?>
<tr>
    <td><?= $row->id_pat ?></td>
    <td><?= $row->id_visit ?></td>
</tr>
<?php endforeach; ?>
</table>

Answer 2

改变这个：

 return $query->ris_array();

收件人：

return $query->result_array();
