笨行（）非對象

Question

我有問題，ION驗證庫上。我想編輯現有的組，當我嘗試D編輯我有這樣的錯誤：

哪裏是錯誤的，我所有的探索和CI文檔，但一切看起來罰款。

Fatal error: Call to a member function row() on a non-object in /var/www/ci_balcanrent/beta/modules/user/controllers/user.php on line 603

下面是編輯功能的控制器：

//edit a group 
    function edit_group($id) { 
     // bail if no group id given 
     if (!$id || empty($id)) { 
      redirect('user', 'refresh'); 
     } 

     $this->data['title'] = $this->lang->line('edit_group_title'); 

     if (!$this->ion_auth->logged_in() || !$this->ion_auth->is_admin()) { 
      redirect('user', 'refresh'); 
     } 

     $group = $this->ion_auth->group($id)->row(); 

     //validate form input 
     $this->form_validation->set_rules('group_name', $this->lang->line('edit_group_validation_name_label'), 'required|alpha_dash|xss_clean'); 
     $this->form_validation->set_rules('group_description', $this->lang->line('edit_group_validation_desc_label'), 'xss_clean'); 

     if (isset($_POST) && !empty($_POST)) { 
      if ($this->form_validation->run() === TRUE) { 
       $group_update = $this->ion_auth->update_group($id, $_POST['group_name'], $_POST['group_description']); 

       if ($group_update) { 
        $this->session->set_flashdata('success', $this->lang->line('edit_group_saved')); 
       } else { 
        $this->session->set_flashdata('error', $this->ion_auth->errors()); 
       } 
       redirect("user", 'refresh'); 
      } 
     } 

     //set the flash data error message if there is one 
     $this->data['message'] = (validation_errors() ? validation_errors() : ($this->ion_auth->errors() ? $this->ion_auth->errors() : $this->session->flashdata('error'))); 

     //pass the user to the view 
     $this->data['group'] = $group; 

     $this->data['group_name'] = array(
      'name' => 'group_name', 
      'id' => 'group_name', 
      'type' => 'text', 
      'value' => $this->form_validation->set_value('group_name', $group->name), 
     ); 
     $this->data['group_description'] = array(
      'name' => 'group_description', 
      'id' => 'group_description', 
      'type' => 'text', 
      'value' => $this->form_validation->set_value('group_description', $group->description), 
     ); 

     $this->template->build('auth/edit_group', $this->data); 
    } 

603線$組= $這個 - > ion_auth->組（$ ID） - >行（）;

型號：

/** 
    * group 
    * 
    * @return object 
    * @author Ben Edmunds 
    **/ 
    public function group($id = NULL) 
    { 
     $this->trigger_events('group'); 

     if (isset($id)) 
     { 
      $this->db->where($this->tables['groups'].'.id', $id); 
     } 

     $this->limit(1); 

     return $this->groups(); 
    } 

查看：

<?php echo form_open(current_url());?> 

     <p> 
      <?php echo lang('create_group_name_label', 'group_name');?> <br /> 
      <?php echo form_input($group_name);?> 
     </p> 

     <p> 
      <?php echo lang('edit_group_desc_label', 'description');?> <br /> 
      <?php echo form_input($group_description);?> 
     </p> 

     <p><?php echo form_submit('submit', lang('edit_group_submit_btn'));?></p> 

<?php echo form_close();?> 

Answer 1

$group = $this->ion_auth->group($id)->row(); 

問題：

$this->ion_auth->group($id)返回group類對象。所以你不能從group類調​​用Datbase row()方法。
