Question

我是CodeIgniter Framework的新手，我试图用分页显示结果，但我有一个分页变量undefined。

这是我的模型：

class Campaign_model extends  CI_Model {

public function __construct() {
    parent::__construct();
}

public function get_campaign_lists($limit, $start) {
    $sql = 'SELECT * FROM ch_campaigns LIMIT '.$limit.', '.$start;
    $query = $this->db->query($sql);
    return $query->result();
}
}

控制器：

class Pagination extends CI_Controller {

public function __construct() {
    parent::__construct();
    $this->load->helper('url');
    $this->load->database();
    $this->load->library('pagination');
    $this->load->model('campaign_model');
}

public function index() {

    //pagination settings
    $config['base_url'] = site_url('pagination/index');
    $config['total_rows'] = $this->db->count_all('ch_campaigns');
    $config['per_page'] = "5";
    $config["uri_segment"] = 1;
    $choice = $config["total_rows"] / $config["per_page"];
    $config["num_links"] = floor($choice);

    //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(1)) ? $this->uri->segment(1) : 0;

    //call the model function to get the department data
    $data['campaignlist'] = $this->campaign_model->get_campaign_list($config["per_page"], $data['page']);           

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

    //load the department_view
    $this->load->view('campaign_view',$data);
}
}

和查看：

<div class="main-container-footer text-center">
    <?php echo $pagination; ?>
</div>

我现在尝试修复此错误一段时间，但仍然没有运气。请帮帮我。

我认为你应该在控制器的方法public function index() { $data = array(); // [...] index method implementation. }的开头添加以下行：

{{1}}

Codeigniter分页变量未定义
