NUM_ROWS問題3.0.3

Question

，當我用笨3.0.3，我得到了NUM_ROWS（）函數無法正常工作的問題...

我有這樣的代碼：

控制器

function search() 
{ 
     // Filter input keyword 
     $keyword = $this->input->get('keyword'); 
     $data['searchtext'] = strip_tags($keyword); 
     $check = strlen(preg_replace('/[^a-zA-Z0-9]/', '', $keyword)); 
     if($check > 3 && $check != NULL): 

      if(isset($_GET['page'])) 
      { 
       $page = ($_GET['page'] != NULL) ? $this->security->xss_clean($_GET['page']) : 1; 
      } 
      else 
      { 
       $page = 1; 
      } 

      $limit = 15; 
      $total = $this->m_songs->total_data_search($keyword); 

      $config['base_url'] = site_url().'songs/search_keyword?keyword='.$keyword; 
      $config['total_rows'] = $total; 
      $config['per_page'] = $limit; 
      $config['page_query_string'] = TRUE; 
      $config['use_page_numbers'] = TRUE; 
      $config['query_string_segment'] = 'page'; 
      $config['uri_segment'] = 4; 
      $config['full_tag_open'] = '<ul class="pagination pagination-sm">'; 
      $config['full_tag_close'] = '</ul>'; 
      $config['first_tag_open'] = '<li>'; 
      $config['first_link'] = '&laquo; First'; 
      $config['first_tag_close'] = '</li>'; 
      $config['last_tag_open'] = '<li class="last-page">'; 
      $config['last_link'] = 'Last &raquo;'; 
      $config['last_tag_close'] = '</li>'; 
      $config['next_link'] = '<span aria-hidden="true">&raquo;</span><span class="sr-only">Next</span>'; 
      $config['next_tag_open'] = '<li>'; 
      $config['next_tag_close'] = '</li>'; 
      $config['prev_link'] = '<span aria-hidden="true">&laquo;</span><span class="sr-only">Previous</span>'; 
      $config['prev_tag_open'] = '<li>'; 
      $config['prev_tag_close'] = '</li>'; 
      $config['cur_tag_open'] = '<li class="active"><a href="#">'; 
      $config['cur_tag_close'] = '</a></li>'; 
      $config['num_tag_open'] = '<li class="page">'; 
      $config['num_tag_close'] = '</li>'; 

      $this->pagination->initialize($config); 

      $offset = ($page == 1) ? 0 : ($page * $config['per_page']) - $config['per_page']; 
      $result = $this->m_songs->get_paging_search($keyword,$limit,$offset); 

      $data['pagination'] = $this->pagination->create_links(); 
      $data['total'] = $total; 

      if($result) 
      { 
       $data['offset'] = $offset; 
       $data['dummies'] = $result; 
      } 
      else 
      { 
       $data['dummies'] = NULL; 
      } 
      else: 
        $data['total'] = 0; 
        $data['dummies'] = NULL; 
        $data['pagination'] = NULL; 
      endif; 


      $data['team'] = $this->m_home->get_team(); 
      $data['contact'] = $this->m_home->get_contact(); 
      $data['pagetitle'] = 'Songs Library'; 
      $data['title'] = 'Tirtasvara Choir & Chamber Orchestra'; 
      $data['body'] = $this->load->view('songs', $data, TRUE); 

      $this->load->view('header'); 
      $this->load->view('songs',$data); 
      $this->load->view('footer'); 
    } 

型號

function total_data_search($keyword) 
{ 
    $query = $this->db->like('no_reg', $keyword) 
         ->or_like('judul_lagu', $keyword) 
         ->or_like('pencipta', $keyword) 
         ->or_like('aransemen', $keyword) 
         ->or_like('penulis_lirik', $keyword) 
         ->or_like('genre', $keyword) 
         ->or_like('gaya', $keyword) 
         ->or_like('bahasa', $keyword) 
         ->or_like('tema', $keyword) 
         ->or_like('masa_liturgi', $keyword) 
         ->or_like('kelompok_ritus', $keyword) 
         ->get('database_lagu'); 

    if($query->num_rows > 0) 
    { 
      return $query->num_rows(); 
    } 
    else 
    { 
     return NULL; 
    } 
} 

查看

<div class="row"> 
    <div class="col-xs-12 col-sm-12 col-md-12"> 
    <?php if(isset($searchtext)): ?> 
     <div class="alert alert-success" role="alert"> 
      <h4>Found <span class="text-info"><?php echo $total; ?></span> reference with keyword: <span class="text-info"><?php echo $searchtext;?></span></h4> 
      </div> 
     <?php endif; ?> 
    </div> 
</div> 

當我做了搜索功能，結果出現了，爲什麼功能產生空的結果？

但是，當我使用CodeIgniter 2.X一切順利。 如果有人能幫助解決這個問題？

Answer 1

您使用$query->num_rows作爲一個屬性在你的if語句。使用它作爲一個方法：

if($query->num_rows() > 0) 
    { 
     return $query->num_rows(); 
    }

與count()

function total_data_search($keyword) 
{ 
    $query = $this->db->like('no_reg', $keyword) 
      ->or_like('judul_lagu', $keyword) 
      ->or_like('pencipta', $keyword) 
      ->or_like('aransemen', $keyword) 
      ->or_like('penulis_lirik', $keyword) 
      ->or_like('genre', $keyword) 
      ->or_like('gaya', $keyword) 
      ->or_like('bahasa', $keyword) 
      ->or_like('tema', $keyword) 
      ->or_like('masa_liturgi', $keyword) 
      ->or_like('kelompok_ritus', $keyword) 
      ->get('database_lagu'); 

    $result = $query->result_array(); 
    $count = count($result); 
    if(!empty($count)) 
    { 
      return $count; 
    } 
    else 
    { 
      return NULL; 
    } 
}
