如何传递url变量到分页 - Codeigniter - How to pass url variable to pagination?

我第一次使用Codeigniter分页库。现在，当用户从搜索表单中搜索任何东西时，我想将URL变量传递到URL末尾的分页，如http://localhost/sitename/brand/campaigns/6/?search="hello"，以在第二页上维护搜索结果。

任何想法如何与codeigniter?

下面是我的代码:

形式

<form name="frmSearch" id="frmSearch" method="get" action="<?php echo base_url(); ?>brand/campaigns">
    <input type="text" name="search" id="search" placeholder="Search campaigns" onchange="return trim(this)">
    <button type="submit" class="search-submit"></button>
</form>

控制器(campaigns_list.php)

public function __construct(){
    parent::__construct();
    $this->load->model('Campaigns_list_model');
    $this->load->library('pagination');
}
public function index($offset=0){
    IsNotLoggedIn(); // Check if a user is not logged in
    // For SEO
    $data['meta_title'] = 'Search';
    $data['meta_descripton'] = '';
    $data['meta_keywords'] = '';
    // Pagination code for campaigns code start
    $config['total_rows'] = $this->Campaigns_list_model->TotalCampaigns();
    // Check status value is number
    $status = $this->uri->segment(3);
    if(!ctype_digit($status)){
        $status = "1";
    }
    $config['base_url'] = base_url()."brand/campaigns/".$status;
    $config['per_page'] = 6;
    $config['uri_segment'] = '4';
    $config['full_tag_open'] = '<div class=""><ul class="pagination pull-right">';
    $config['full_tag_close'] = '</ul></div>';
    $config['first_link'] = '« First';
    $config['first_tag_open'] = '<li class="prev page">';
    $config['first_tag_close'] = '</li>';
    $config['last_link'] = 'Last »';
    $config['last_tag_open'] = '<li class="next page">';
    $config['last_tag_close'] = '</li>';
    $config['next_link'] = 'Next →';
    $config['next_tag_open'] = '<li class="next page">';
    $config['next_tag_close'] = '</li>';
    $config['prev_link'] = '← Previous';
    $config['prev_tag_open'] = '<li class="prev page">';
    $config['prev_tag_close'] = '</li>';
    $config['cur_tag_open'] = '<li class="active"><a href="">';
    $config['cur_tag_close'] = '</a></li>';
    $config['num_tag_open'] = '<li class="page">';
    $config['num_tag_close'] = '</li>';
    $this->pagination->initialize($config);
    $query = $this->Campaigns_list_model->GetCampaigns(6, $this->uri->segment(4));
    $data['Campaigns'] = null;
    if($query){
        $data['Campaigns'] =  $query;
    }
    // Pagination code for campaigns code end
    $this->load->view('include/brand_header', $data);
    $this->load->view('brand/campaigns_list', $data);
    $this->load->view('include/brand_footer');
}

<?php
defined('BASEPATH') OR exit('No direct script access allowed');
class My_controller extends CI_Controller {
    public function __construct() {
            parent::__construct();
            //here we will autoload the pagination library
            $this->load->library('pagination');
        }
    public function paginationExample()
    {
        //echo $this->uri->segment(2);die;
        $config = array();
        $config["base_url"] = base_url('My_controller/paginationExample');
        $config['total_rows'] =   $this->db->count_all("Your table");//here we will count all the data from the table
        $config['per_page'] = 5;//number of data to be shown on single page
        $config["uri_segment"] = 2;
        $this->pagination->initialize($config);
        $page = ($this->uri->segment(2)) ? $this->uri->segment(2) : 0;
        $data["allData"] = $this->My_model->paginationExample($config["per_page"], $page);
        $data["links"] = $this->pagination->create_links();//create the link for pagination
        $this->load->view('your view',$data);
    }
}

是否需要在url中使用搜索标签?我的意思是，你可以把搜索标签保存在一个会话变量中，也许可以使用它。这是我通常根据情况做的。这应该是，如果你有一种方法让用户重置他的搜索条件。

如果你确实需要这样使用它，你可以这样做:

if (count($_GET) > 0) $config['suffix'] = '?' . http_build_query($_GET, '', "&");
