使用codeigniter中的下一个和上一个按钮进行分页

Question

我尝试使用以下代码在 CodeIgniter 中添加分页，它带有 1 2 3 4 5 > 这种格式。但我需要添加下一个和上一个按钮。控制器：

public function chooseBale($program_id = '')

{

    $config                = [];

    $config["base_url"]    = base_url() . "ginner/choosebale/" . $program_id;

    $config["total_rows"]  = $this->GinnerModel->get_count();

    $config["per_page"]    = 10;

    $config["uri_segment"] = 2;

    $choice                = $config["total_rows"] / $config["per_page"];

    $config["num_links"]   = round($choice);

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

    $page          = ($this->uri->segment(4)) ? $this->uri->segment(4) : 0;

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

    $data['pg_title']   = 'Choose Bale';

    $data['breadcrumb'] = ['Home' => '', 'Sale' => 'nolink', 'New Process' => 'nolink', 'Choose Bale' => 'nolink'];

    $data['left_menu']  = "left-menu-ginner.php";

    $data['program']    = $this->CommonModel->getTableWhere(PROGRAM, 'id =' . $program_id);

    $data['program_id'] = $program_id;

    $data['bale_list']  = $this->GinnerModel->baleList($program_id, $config["per_page"], $page);

    $this->load->view('common/header', $data);

    $this->load->view('ginner/choose-bale');

    $this->load->view('common/footer');

}

我在模型文件中使用了以下查询来获取限制明智的记录。模型：

public function baleList($program_id, $per_page, $page)

{

    $this->db->select('gp.id, gp.lot_no, SUM(gb.weight) AS weight, SUM(gb.staple) AS staple, SUM(gb.mic) AS mic, SUM(gb.strength) AS strength, SUM(gb.trash) AS trash, gb.color_grade');

    $this->db->from(GIN_BALES . ' gb');

    $this->db->join(GIN_PROCESS . ' gp', 'gp.id=gb.process_id');

    $this->db->where('gb.sold_status', 0);

    $this->db->where('gp.ginner_id', $this->prscr_id);

    $this->db->where('gp.program', $program_id);

    $this->db->group_by('gp.id');

看法：

<p><?php echo $links; ?></p>

我在查看页面代码的表格下添加了此链接代码。分页工作到箭头到达第一页后的 5 个部分。所以我无法查看分页的第 6 页。是否需要在控制器或模型文件中进行其他更正才能以正确的方式显示分页？

Answer 1

见下面的代码，我们通过配置库配置分页链接&nbsp; &nbsp; $this->load->library("pagination");&nbsp; &nbsp; $config = array();&nbsp; &nbsp; $config["base_url"] = base_url() . "blogs";&nbsp; &nbsp; $config["total_rows"] = $this->blog->getBlogCount();&nbsp; &nbsp; $config["per_page"] = 10;&nbsp; &nbsp; $config["uri_segment"] = 2;&nbsp; &nbsp; $config['full_tag_open'] = "<ul class='pagination'>";&nbsp; &nbsp; $config['full_tag_close'] = '</ul>';&nbsp; &nbsp; $config['num_tag_open'] = '<li>';&nbsp; &nbsp; $config['num_tag_close'] = '</li>';&nbsp; &nbsp; $config['cur_tag_open'] = '<li class="active"><a href="#">';&nbsp; &nbsp; $config['cur_tag_close'] = '</a></li>';&nbsp; &nbsp; $config['prev_tag_open'] = '<li>';&nbsp; &nbsp; $config['prev_tag_close'] = '</li>';&nbsp; &nbsp; $config['first_tag_open'] = '<li>';&nbsp; &nbsp; $config['first_tag_close'] = '</li>';&nbsp; &nbsp; $config['last_tag_open'] = '<li>';&nbsp; &nbsp; $config['last_tag_close'] = '</li>';&nbsp; &nbsp; $config['prev_link'] = 'Previous';&nbsp; &nbsp; $config['prev_tag_open'] = '<li>';&nbsp; &nbsp; $config['prev_tag_close'] = '</li>';&nbsp; &nbsp; $config['next_link'] = 'Next';&nbsp; &nbsp; $config['next_tag_open'] = '<li>';&nbsp; &nbsp; $config['next_tag_close'] = '</li>';&nbsp; &nbsp; $this->pagination->initialize($config);

请检查官方分页文档：https : //www.codeigniter.com/user_guide/libraries/pagination.html#customizing-the-previous-link 这是示例。&nbsp; &nbsp; &nbsp; &nbsp; $config['base_url'] = base_url() . 'paging/custom';&nbsp; &nbsp; &nbsp; &nbsp; $config['total_rows'] = $total_records;&nbsp; &nbsp; &nbsp; &nbsp; $config['per_page'] = $limit_per_page;&nbsp; &nbsp; &nbsp; &nbsp; $config["uri_segment"] = 3;&nbsp; &nbsp; &nbsp; &nbsp; // custom paging configuration&nbsp; &nbsp; &nbsp; &nbsp; $config['num_links'] = 2;&nbsp; &nbsp; &nbsp; &nbsp; $config['use_page_numbers'] = TRUE;&nbsp; &nbsp; &nbsp; &nbsp; $config['reuse_query_string'] = TRUE;&nbsp; &nbsp; &nbsp; &nbsp; $config['full_tag_open'] = '<div class="pagination">';&nbsp; &nbsp; &nbsp; &nbsp; $config['full_tag_close'] = '</div>';&nbsp; &nbsp; &nbsp; &nbsp; $config['first_link'] = 'First Page';&nbsp; &nbsp; &nbsp; &nbsp; $config['first_tag_open'] = '<span class="firstlink">';&nbsp; &nbsp; &nbsp; &nbsp; $config['first_tag_close'] = '</span>';&nbsp; &nbsp; &nbsp; &nbsp; $config['last_link'] = 'Last Page';&nbsp; &nbsp; &nbsp; &nbsp; $config['last_tag_open'] = '<span class="lastlink">';&nbsp; &nbsp; &nbsp; &nbsp; $config['last_tag_close'] = '</span>';&nbsp; &nbsp; &nbsp; &nbsp; $config['next_link'] = 'Next Page';&nbsp; &nbsp; &nbsp; &nbsp; $config['next_tag_open'] = '<span class="nextlink">';&nbsp; &nbsp; &nbsp; &nbsp; $config['next_tag_close'] = '</span>';&nbsp; &nbsp; &nbsp; &nbsp; $config['prev_link'] = 'Prev Page';&nbsp; &nbsp; &nbsp; &nbsp; $config['prev_tag_open'] = '<span class="prevlink">';&nbsp; &nbsp; &nbsp; &nbsp; $config['prev_tag_close'] = '</span>';&nbsp; &nbsp; &nbsp; &nbsp; $config['cur_tag_open'] = '<span class="curlink">';&nbsp; &nbsp; &nbsp; &nbsp; $config['cur_tag_close'] = '</span>';&nbsp; &nbsp; &nbsp; &nbsp; $config['num_tag_open'] = '<span class="numlink">';&nbsp; &nbsp; &nbsp; &nbsp; $config['num_tag_close'] = '</span>';&nbsp; &nbsp; &nbsp; &nbsp; $this->pagination->initialize($config);&nbsp; &nbsp; &nbsp; &nbsp; // build paging links&nbsp; &nbsp; &nbsp; &nbsp; $params["links"] = $this->pagination->create_links();&nbsp; &nbsp; &nbsp;
