我做分页，但它不能限制每个页面后笨

Question

这是我的控制，我使用$config['per_page']来限制我的职位，但它不是在它还是所有的工作我的数据库显示，

function index() 

{ 

    $jumlah_data = $this->m_berita->jumlah_data(); 

    $config['base_url'] = base_url().'berita/index/'; 
    $config['total_rows'] = $jumlah_data; 
    $config['per_page'] = 2; 
    $from = $this->uri->segment(3); 

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

    $halaman['berita'] = $this->m_berita->data($config['per_page'],$from); 

    $urutan['berita'] = $this->db->order_by("id", "desc"); 

    $data['berita'] = $this->m_berita->data_berita()->result(); 

    $this->load->view('artikel', $data, $urutan, $halaman);  

} 

我的模型

class m_berita extends CI_Model{ 

public function __construct() 

    { 
     $this->load->database(); 
    } 

    public function data_berita(){ 
     return $this->db->get('berita'); 

    } 

    public function data($number,$offset){ 
     return $query = $this->db->get('berita',$number,$offset)->result(); 
    } 

    function jumlah_data(){ 
     return $this->db->get('berita')->num_rows(); 
    } 

，这我认为

<?php 
$no = $this->uri->segment('3') + 1; 
foreach ($berita as $u) { 
?> 

<?php $no++;?> 
<div class="container"> 
<?php $u->id; ?> 
    <h4> <?php echo $u->judul; ?> </h4> 
    <span style="margin-bottom: 5%;" class="image left 3u"><img class="fit" src="<?php echo base_url('images/').$u->gambar; ?>" alt="" /></span> 
    <?php $artikel = $u->isi; $artikel=word_limiter($artikel, 98); ?> <?php echo $artikel;?> <?php echo anchor('berita/tampil_berita/'.$u->id,'Read More'); ?> 
</div> 

<?php } ?> 
<div class="container"> 
<ul class="pagination"> 
    <li><?php echo $this->pagination->create_links(); ?></li> 
</ul> 
</div> 

Answer 1

改DB函数

到

function jumlah_data(){ 
    return $this->db->count_all('berita'); 
} 

Answer 2

控制器代码：

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

$config['base_url'] = 'base_url().'berita/index/'; 

$config['total_rows'] = $this->db->get('berita')->num_rows(); 

$config['next_link'] = 'Next'; 

$config['prev_link'] = 'Previous'; 

$config['uri_segment'] = 4; 

$config['per_page'] = 10; 

$config['num_links'] = 20; 

$config['full_tag_open'] = '<div id="pagination" class="pagination">'; 

$config['full_tag_close'] = '</div>'; 

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

$this->data['berita'] = $this->m_berita->data_berita($config['per_page']); 

型号代码：

function data_berita($per_page) { 

     $query = $this->db->get('berita', $per_page, $this->uri->segment(3)); 

     return $query->result_array(); 

    } 

查看代码：

echo $this->pagination->create_links(); 

和然后循环
