我正在为我的网站进行分页，我正在显示来自数据库上两个表的数据我在我的页面中有分页但它的行为不像它假设的那样表现它不会改变页面。目前我在网页上显示了 16 条记录，并且已将$config['per_page'] = 1;分页栏设置为 16，但它不会翻阅页面，所有记录都显示在页面上。任何帮助将不胜感激，这是我的代码：

控制器

 <?php

class Result_controller extends CI_Controller{

    function getall(){

        $this->load->model('result_model');
        $data['query'] = $this->result_model->result_getall();
        // print_r($data['query']); die();


        $this->load->library('pagination');

        $config['base_url'] = 'http://localhost/Surva/index.php/result_controller/getall';
        $config['total_rows'] = $this->db->get('tblanswers, credentials')->num_rows();
        $config['per_page'] = 1;
        $config['num_links'] = 10;


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

        $data['records'] = $this->db->get('tblanswers, credentials', $config['per_page'], $this->uri->segment(1, 0))->result_array();
        $data['pagination'] = $this->pagination->create_links();
        $this->load->view('result_view', $data);




        }


}

?>

看法

   <div>    






     <table border="1">


      <tr>
         <th>Name</th>
         <th>Second Name</th>
         <th>Phone</th>
         <th>Email</th>
         <th>Answer</th>
         <th>Comment</th>
     </tr>
      <?php foreach ($query as $row): ?> 
     <tr>

         <td><?php echo $row->name; ?></td>
         <td><?php echo $row->second_name; ?></td>
         <td><?php echo $row->phone; ?></td>
         <td><?php echo $row->email; ?></td>
          <td> <?php echo $row->answerA;?>
          <?php echo $row->answerB;?>
          <?php echo $row->answerC;?></td>
         <td><?php echo $row->comment;?><br></td>

     </tr>

      <?php endforeach; ?>

     </table>  
     <?php if (isset($pagination))
      {
       echo $pagination;
      // echo "<pre>"; var_dump($query);
       } ?>

模型

function result_getall(){

   return $this->db->select('tblanswers.*,credentials.*')
                         ->from('tblanswers, credentials')
                         ->get()
                         ->result_object();

查询并不神奇地知道您只需要 x 条记录。Codeigniter 将显示您从模型中输入的任何内容。

function getall(){

        $this->load->model('result_model');
        // print_r($data['query']); die();


        $this->load->library('pagination');

        $config['base_url'] = 'http://localhost/Surva/index.php/result_controller/getall';
        $config['total_rows'] = $this->db->get('tblanswers, credentials')->num_rows();
        $config['per_page'] = 1;
        $config['num_links'] = 10;
        $config['uri_segment'] = 3; //guessing here, but this is where the uri segment you use to change pages goes.
        if($this->uri->segment('3')) {
        $offest = $this->uri->segment('3');
        } else {
        $offest = 0;
        }
        $data['query'] = $this->result_model->result_getall($config['per_page'],$offset);


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

        $data['records'] = $this->db->get('tblanswers, credentials', $config['per_page'], $this->uri->segment(1, 0))->result_array();
        $data['pagination'] = $this->pagination->create_links();
        $this->load->view('result_view', $data);




        }



Model:

function result_getall($limit=0,$offset=0){

   if($limit != 0)
   {
   return $this->db->select('tblanswers.*,credentials.*')
                         ->from('tblanswers, credentials')
                         ->limit($limit, $offset)
                         ->get()
                         ->result_object();
   } else {
   return $this->db->select('tblanswers.*,credentials.*')
                         ->from('tblanswers, credentials')
                         ->get()
                         ->result_object();
   }

请注意，在控制器中，我将偏移量和每页传递给模型，然后使用它们来限制模型本身的返回。

您应该循环通过 $records 而不是 $query。$query 包含所有记录。

这样做

    $this->load->library('pagination');
    $limit = 10;

    $total = $this->legend_model->get_legend_count($language_id);

    $config['base_url'] = base_url().'legend/index/';
    $config['total_rows'] = $total;
    $config['per_page'] = $limit;
    $config['uri_segment'] = 3;

    $config['first_link'] = '<< First';
    $config['last_link'] = 'Last >>';
    $config['next_link'] = 'Next ' . '&gt;';
    $config['prev_link'] = '&lt;' . ' Previous';
    $config['num_tag_open'] = '<span class="number">';
    $config['num_tag_close'] = '</span>';

    $config['cur_tag_open'] = '<span class="current"><a href="#">';
    $config['cur_tag_close'] = '</a></span>';

    $this->pagination->initialize($config);
    $data['offset'] = $offset;
    $data['legends'] = $this->legend_model->get_legend($language_id, $limit, $offset);

    $this->template->write('title', 'Legend : Manage Legend');
    $this->template->write_view('content', 'legend/index', $data);
    $this->template->render();
