我是CodeIgniter的新手。我被困在一些寻找分页的地方。有人帮助我。
class Pagination2 extends My_controller {
public function __construct()
{
parent::__construct();
$this->load->helper('form');
$this->load->helper('url');
$this->load->database();
$this->load->library('pagination');
$this->load->model('pagination_model');
$userdata=$this->session->userdata('userdata');
if(!isset($userdata['user_role']))
{
redirect(base_url('admin'));
}
}
public function manage($page = 0)
{
$this->load->library('pagination');
$per_page = 10;
$_POST = $_GET;
$search= $this->input->get('book_name')?$this->input->get('book_name'):'NIL';
$this->db->limit($per_page,$page);
if($search=='NIL')
{
$data['content_fb'] = $this->db->get('tbl_books')->result();
}
else
{
$this->db->like('name', $search);
$res = $this->db->get('tbl_books');
$data['content_fb'] = $res->result();
}
// $data['content_fb'] = $this->db->select('id')->limit($per_page,$page)->get('content_fb')->result();
$config['base_url'] = base_url('pagintion2/manage');
$config['total_rows'] = $this->db->count_all('tbl_books');
$config['per_page'] = $per_page;
$choice = $config["total_rows"]/$config["per_page"];
$config["num_links"] = floor($choice);
$config['use_page_numbers'] = TRUE;
$config['page_query_string'] = TRUE;
$config['uri_segment'] = 3;
$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'] = '«';
$config['prev_tag_open'] = '<li class="prev">';
$config['prev_tag_close'] = '</li>';
$config['next_link'] = '»';
$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>';
$config['num_tag_close'] = '</li>';
// CodeIgniter Pagination URL with GET Parameters
// http://subhra.me/codeigniter-pagination-url-get-parameters/
if (count($_GET) > 0) $config['suffix'] = '?' . http_build_query($_GET, '', "&");
$config['first_url'] = $config['base_url'].'?'.http_build_query($_GET);
$this->pagination->initialize($config);
$data['pagination_links'] = $this->pagination->create_links();
// echo $data['pagination_links'];
$data['templatepart']='backend/pagination2';
$userdata= $this->session->userdata('userdata');
$data['data']= $this->Admin_model->getdata('user',array('id'=>$userdata['id']));
$this->load->view('backend/layout',$data);
}
}
问题：
当我生成查询字符串时，例如。 ？per_page = 2给我一个致命的错误，并且无法操纵查询字符串。
例如：
localhost/xxx/pagintion2/manage?per_page=2&book_name=Learning
错误：
404 Page Not Found
请给我一些解决方案。如果您有重新编码的代码，请与我分享。
问候

1.创建用于保存查询的SQL表
--
-- Table structure for table `ci_query`
--
CREATE TABLE `ci_query` (
`id` int(11) NOT NULL,
`query_string` text,
`date_created` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP
) ENGINE=MyISAM DEFAULT CHARSET=utf8;
cerate文件：My_input.php
if (!defined('BASEPATH')) exit('No direct access allowed.');
/**
* Description of My_input
*
* @author Dragan
*/
class MY_Input extends CI_Input{
function __construct() {
parent::__construct();
}
/**
* Save query in database
*/
function save_query($query_array){
$CI =& get_instance();
$CI->db->insert('ci_query', array('query_string' => http_build_query($query_array)));
return $CI->db->insert_id();
}
/**
* Load query from database
*/
function load_query($query_id) {
$CI =& get_instance();
$rows = $CI->db->get_where('ci_query', array('id' => $query_id))->result();
if (isset($rows[0])) {
parse_str($rows[0]->query_string, $_GET);
}
}
}
在您的Controller cerate功能
中 public function search() {
$query_array = array(
'book_name' => $this->input->post('book_name')
);
$query_id = $this->input->save_query($query_array);
redirect("pagintion2/manage/$query_id");
}
更改您的管理功能
public function manage ($query_id = 0,$start=0){
$this->input->load_query($query_id);
$query_array = array(
'book_name' => $this->input->get('book_name')
);
$per_page = 10;
$search= $this->input->get('book_name')?$this->input->get('book_name'):'NIL';
if($search=='NIL')
{
$data['content_fb'] = $this->db->get('tbl_books')->result();
}
else
{
$this->db->like('name', $search);
$res = $this->db->get('tbl_books');
$data['content_fb'] = $res->result();
}
$this->load->library('pagination');
$config['base_url'] = site_url()."pagintion2/manage/$query_id";
$config['total_rows'] = $this->db->count_all('tbl_books');
$config['uri_segment'] = 4;
$config['per_page'] = 10;
$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'] = '«';
$config['prev_tag_open'] = '<li class="prev">';
$config['prev_tag_close'] = '</li>';
$config['next_link'] = '»';
$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['pagination_links'] = $this->pagination->create_links();
// output search data
$data['list_of_books_by_category'] = $this->model_your_model_name->get_list_of_books_by_category($query_array, $per_page, $start);
$data['templatepart']='backend/pagination2';
$userdata= $this->session->userdata('userdata');
$data['data']= $this->Admin_model->getdata('user',array('id'=>$userdata['id']));
$this->load->view('backend/layout',$data);
