我的分页在Codeigniter控制器中不起作用

Question

我的codeigniter控制器遇到问题，该分页代码无法正常工作：

function index()
{
    $data['title'] = "Hope Center - Home";

    $config['base_url'] = base_url().'Home';

    $config['total_rows'] = $this->donation_model->get_search_count();
    $config['per_page'] = 3;
    $config['uri_segment'] = 3;
    $config['full_tag_open'] = '<ul class="pager">';
    $config['full_tag_close'] = '</ul>';
    $config['num_tag_open'] = '<li class="rounds">';
    $config['num_tag_close'] = '</li>';
    $config['cur_tag_open'] = '<li class="rounds active"><a class="page-link" href="#">';
    $config['cur_tag_close'] = '</a></li>';
    $config['next_tag_open'] = '<li class="next">';
    $config['next_tagl_close'] = '</a></li>';
    $config['prev_tag_open'] = '<li class="previous">';
    $config['prev_tagl_close'] = '</li>';
    $config['first_tag_open'] = '<li class="rounds disabled">';
    $config['first_tagl_close'] = '</li>';
    $config['last_tag_open'] = '<li class="rounds">';
    $config['last_tagl_close'] = '</a></li>';
    $config['attributes'] = array('class' => 'page-link');
    $this->pagination->initialize();
    $data['donation_info'] = $this->donation_model->get_donation_info($config['per_page'],$this->uri->segment(3));

    $this->load->view('frontend/layouts/header',$data);
    $this->load->view('frontend/home',$data);
    $this->load->view('frontend/layouts/footer');
}

我在上面添加了完整的控制器功能代码。
