Question

为什么我在同一页面中获取所有数据？

该函数正在工作，因为它将页面（1,2,3）显示为数据库表中的数据数。但是在一页中显示数据。

我的应用程序的控制器页面调用引导程序分页

public function reportTransaction(){
    //pagination settings followed from that tutorial
    //base url defined application
    $config['base_url'] = site_url('inventory/reportTransaction'); 

    //code that gets rows from the transaction model
    $config['total_rows'] = $this->transactionLog->countAll();

    //defined per page as 5
    $config['per_page'] = 5; 

    $config["uri_segment"] = 3; 
    $choice = $config["total_rows"] / $config["per_page"];
    $config["num_links"] = ceil($choice);

    //echo $config["num_links"];

   //config for bootstrap pagination class integration
    $config['full_tag_open'] = '<ul class="pagination">';
    $config['full_tag_close'] = '</ul>';
    $config['first_link'] = false;
    $config['last_link'] = false;
    $config['first_tag_open'] = '<li>';
    $config['first_tag_close'] = '</li>';
    $config['prev_link'] = '&laquo';
    $config['prev_tag_open'] = '<li class="prev">';
    $config['prev_tag_close'] = '</li>';
    $config['next_link'] = '&raquo';
    $config['next_tag_open'] = '<li>';
    $config['next_tag_close'] = '</li>';
    $config['last_tag_open'] = '<li>';
    $config['last_tag_close'] = '</li>';
    $config['cur_tag_open'] = '<li class="active"><a href="#">';
    $config['cur_tag_close'] = '</a></li>';
    $config['num_tag_open'] = '<li>';
    $config['num_tag_close'] = '</li>';

    $this->pagination->initialize($config);
    $data['page'] = ($this->uri->segment(3)) ? $this->uri->segment(3) : 0;

    //call the model function to get the transaction data
    $data['posts'] = $this->transactionLog->get_report();           
    $data['pagination'] = $this->pagination->create_links();

    //print_r($data['posts']);
    //load the department_view
    $this->load->view('admin/reportTransaction', $data);
    $this->header();
    $this->footer();
}

在控制器中调用的模型

function get_report($limit = null)
    {
        if ($limit != null) {
            $this->db->limit($limit['limit'], $limit['offset']);
        }

        $q = $this->db->query("SELECT `transaction`.`transaction_id`, ABS(`cost`) as cst,`transaction`.`date_posted`, ABS(`unit`) as unt, `detail`.`name` as sam, `product`.`productName` as pam, `transaction`.`type` FROM `transaction` INNER JOIN `detail` ON `detail`.`type`=`transaction`.`type` INNER JOIN `product` ON `product`.`product_id`=`transaction`.`product_id`");

//        $q = $this->db->get($this->table);

        if ($q->num_rows() > 0) {
            foreach ($q->result() as $row)
            {
                $data[] = $row;
            }
        }
        return $data;
    }

    function countAll()
    {
        return $this->db->count_all($this->table);
    }

查看显示控制器数据的应用程序的页面！这是在同一页面中显示数据的表

   <table class="table tablesorter table-bordered table-hover table-striped sortable">
             <thead>
                <tr>
                    <th>S/B Name</th>
                    <th>Product Name</th>
                   <th>Unit</th>
                   <th>Date Posted</th>
                </tr>
             </thead>
             <tbody>
                <?php $i=1; foreach($posts as $post): ?>
                <tr <?=($i % 2 == 0) ? 'class="even"' : '' ?>>
                    <td><?=$post->sam?></td>
                    <td><?=$post->pam?></td>
                  <td><?=$post->unt?></td>
                   <td><?=$post->date_posted?></td>
                </tr>
                <?php $i++; endforeach; ?>
             </tbody>
          </table>
       <div class="row">
          <div class="col-md-12 text-center">
              <p><?php echo $pagination; ?></p>
          </div>
      </div>
    </div>

到达系统的问题所有数据都显示在同一页面中分页页码根据数据增加，但数据显示在同一个表中

将get_report()更改为以下

public function get_report($segment,$per_page)
{
  $data = array();

    $q = $this->db->query('SELECT `transaction`.`transaction_id`, ABS(`cost`) as cst,`transaction`.`date_posted`, ABS(`unit`) as unt, `detail`.`name` as sam, `product`.`productName` as pam, `transaction`.`type` FROM `transaction` INNER JOIN `detail` ON `detail`.`type`=`transaction`.`type` INNER JOIN `product` ON `product`.`product_id`=`transaction`.`product_id` LIMIT '.$segment.', '.$per_page);

    if ($q->num_rows() > 0) {
        $data = $q->result_array()
    }
    return $data;
}

现在使用LIMIT参数

在控制器中调用它

$data['posts'] = $this->transactionLog->get_report($data['page'],$config['per_page']);

现在检查

Codeigniter Bootstrap分页（页面显示同一表中的所有数据）
