为什么 Codeigniter 使用分页在每个页面上显示相同的数据？

Question

Codeigniter 使用分页在每个页面上显示相同的数据。我认为URL 存在问题，因为它无法从 url 获取 3rd uri 段。

http://127.0.0.1/hmvc/business_list/?p=2

而我使用的代码是……

public function index()
{



    $query = $this->db->query('SELECT * FROM categories');
    $pagination_limit = '10';

    $config = array();
    $config['base_url'] = base_url().'business_list/';

    $config['display_pages'] = true;
    $config['first_link'] = 'First';

    $config['total_rows'] = $query->num_rows();
    $config['per_page'] = $pagination_limit;
    $config['uri_segment'] = 3;

    $config['full_tag_open'] = "<ul class='pagination pagination-right margin-none'>";
    $config['full_tag_close'] = '</ul>';
    $config['num_tag_open'] = '<li>';
    $config['num_tag_close'] = '</li>';
    $config['cur_tag_open'] = "<li class='disabled'><li class='active'><a href='#'>";
    $config['cur_tag_close'] = "<span class='sr-only'></span></a></li>";
    $config['next_tag_open'] = '<li>';
    $config['next_tagl_close'] = '</li>';
    $config['prev_tag_open'] = '<li>';
    $config['prev_tagl_close'] = '</li>';
    $config['first_tag_open'] = '<li>';
    $config['first_tagl_close'] = '</li>';
    $config['last_tag_open'] = '<li>';
    $config['last_tagl_close'] = '</li>';

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

    $page = ($this->uri->segment(3)) ? $this->uri->segment(3) : 0;

    $data['results'] = $this->Business_model->fetch_comments_data($config['per_page'], $page);

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

     $data['title'] = "Business List";

    $this->load->view('categories',$data);

}

请帮忙。

Answer 1

你需要改变这个：

$page = ($this->uri->segment(3)) ? $this->uri->segment(3) : 0;

到

$page = ($this->input->get('p') ? $this->input->get('p') : 0);

我认为 Codeigniter URI Segment 在您的情况下不起作用，因为如果您的网址是这样的

http://127.0.0.1/hmvc/business_list/page/2

那么第一段是business_list，第二段是page，但是您使用查询字符串，所以需要更改

Answer 2

花点时间了解一下你在那里做什么。

$query = $this->db->query('SELECT * FROM categories');

您似乎没有定义 LIMIT 和 OFFSET。
