为什么在 CodeIgniter 中分页链接对我不起作用?-php问题

Why are pagination links not working for me in CodeIgniter?(为什么在 CodeIgniter 中分页链接对我不起作用?)

本文介绍了为什么在 CodeIgniter 中分页链接对我不起作用?的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我正在尝试为我的产品使用 codeigniter 分页，因此有多个页面哪些产品但对我不起作用，我不知道为什么..

这是我的控制器中的分页功能:

//code om in allecadeaus te bepalen hoeveel producten er per pagina zitten公共功能分页(){//加载分页库$this->load->library('分页');//laad Products_model voor分页$this->load->model('Pagination_model');$this->load->model('Product_model');$config = array();$config["base_url"] = base_url() ."AlleCadeausController/分页";$config["total_rows"] = $this->products->record_count();$config["per_page"] = 24;$config['cur_tag_open'] = '<a><b class="text-success">';$config['cur_tag_close'] = '</b></a>';$config["uri_segment"] = 3;$config['use_page_numbers'] =True;$config['enable_query_strings'];$this->分页->初始化($config);$page = ($this->uri->segment(3)) ?$this->uri->segment(3) : 0;$data['title'] = "产品";$data['products'] = $this->Product_model->selectProducts();$data["links"] = $this->分页->create_links();$this->load->view("allecadeaus", $data);}

通过这条线，我从产品表中获取所有产品:

$data['products'] = $this->Product_model->selectProducts();

我的分页模型:

db->count_all("products");}公共函数 fetch_products($limit, $start) {$this->db->limit($limit, $start);$query = $this->db->get_where('users',array('Is_Hidden'=>0));如果 ($query->num_rows() > 0) {foreach ($query->result() as $row) {$data[] = $row;}返回 $data;}返回假；}?>

在我的所有产品页面上，我现在尝试回显链接，但它不起作用.我没有看到正确的链接，只有 1 个链接指向其他内容.这是我在所有产品页面上查看的代码:

<li><?php echo $links;?></li>
</nav></div>

我做错了什么?

解决方案

请做如下修改:

控制器:

公共函数分页($row = 0) {//加载分页库$this->load->library('分页');//laad Products_model voor分页$this->load->model('Pagination_model');$this->load->model('Product_model');$config = array();$limit = '24';$config['base_url'] = site_url() .'/AlleCadeausController/分页';$config['full_tag_open'] = "";$config['full_tag_close'] = '
';$config['num_tag_open'] = '';$config['num_tag_close'] = '
';$config['cur_tag_open'] = '<li class="active"><a href="#">';$config['cur_tag_close'] = '</a></li>';$config['prev_tag_open'] = '';$config['prev_tag_close'] = '</li>';$config['first_tag_open'] = '
';$config['first_tag_close'] = '</li>';$config['last_tag_open'] = '
';$config['last_tag_close'] = '</li>';$config['prev_link'] = '<i class="fa fa-long-arrow-left"></i>上一页';$config['prev_tag_open'] = '
';$config['prev_tag_close'] = '</li>';$config['next_link'] = '下一页<i class="fa fa-long-arrow-right"></i>';$config['next_tag_open'] = '';$config['next_tag_close'] = '</li>';$config["total_rows"] = $this->Product_model->record_count();$config['per_page'] = $limit;$this->分页->初始化($config);$data['links'] = $this->pagination->create_links();$data['products'] = $this->Product_model->selectProducts($row,$limit);$this->load->view("allecadeaus", $data);}

型号:

function selectProducts($row,$limit){$query = $this->db->get('Your_table_name',$limit,$row);如果 ($query->num_rows() > 0){返回 $query->result_array();}别的 {返回数组()；}}函数记录计数(){$this->db->from('Your_table_name');$query = $this->db->get();$row = $query->num_rows();返回 $row;}

这会帮助你..谢谢！

I'm trying to use codeigniter pagination for my products so there are multiple pages which products but its not working for me and I don't know why..

This is my pagination function in my controller:

//code om in allecadeaus te bepalen hoeveel producten er per pagina zitten
   public function pagination() {
        //load pagination library
        $this->load->library('pagination');
        //laad Products_model voor pagination
        $this->load->model('Pagination_model');
        $this->load->model('Product_model');

        $config = array();
        $config["base_url"] = base_url() . "AlleCadeausController/pagination";
        $config["total_rows"] = $this->products->record_count();
        $config["per_page"] = 24;
        $config['cur_tag_open'] = '<a><b class="text-success">';
        $config['cur_tag_close'] = '</b></a>';
        $config["uri_segment"] = 3;
        $config['use_page_numbers'] =True;
        $config['enable_query_strings'];

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

        $page = ($this->uri->segment(3)) ? $this->uri->segment(3) : 0;
        $data['title'] = "Products";
        $data['products'] = $this->Product_model->selectProducts();
        $data["links"] = $this->pagination->create_links();

        $this->load->view("allecadeaus", $data);
    }

with this line I'm getting all the products from product table:

$data['products'] = $this->Product_model->selectProducts();

My pagination model:

<?php
class Pagination_model extends CI_Model
{

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

    public function record_count() {
        return $this->db->count_all("products");
    }

     public function fetch_products($limit, $start) {
        $this->db->limit($limit, $start);
        $query = $this->db->get_where('users',array('Is_Hidden'=>0));

        if ($query->num_rows() > 0) {
            foreach ($query->result() as $row) {
                $data[] = $row;
            }
            return $data;
        }
        return false;
    }

?>

On my all products page I now tried to echo links but it doesn't work. I don't see the correct links and its just 1 link that leads to something else. This is the code in my view on the all products page:

<div class="text-center"><nav aria-label="Page navigation">
                                            <ul class="pagination">

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

                                            </ul>
                                        </nav></div>

What am I doing wrong?

解决方案

Please make some changes as follows:

Controller:

public function pagination($row = 0) {
     //load pagination library
        $this->load->library('pagination');
        //laad Products_model voor pagination
        $this->load->model('Pagination_model');
        $this->load->model('Product_model');
        $config = array();
        $limit = '24';      
        $config['base_url'] = site_url() . '/AlleCadeausController/pagination';
        $config['full_tag_open'] = "<ul class='pagination'>";
        $config['full_tag_close'] = '</ul>';
        $config['num_tag_open'] = '<li>';
        $config['num_tag_close'] = '</li>';
        $config['cur_tag_open'] = '<li class="active"><a href="#">';
        $config['cur_tag_close'] = '</a></li>';
        $config['prev_tag_open'] = '<li>';
        $config['prev_tag_close'] = '</li>';
        $config['first_tag_open'] = '<li>';
        $config['first_tag_close'] = '</li>';
        $config['last_tag_open'] = '<li>';
        $config['last_tag_close'] = '</li>';
        $config['prev_link'] = '<i class="fa fa-long-arrow-left"></i>Previous Page';
        $config['prev_tag_open'] = '<li>';
        $config['prev_tag_close'] = '</li>';
        $config['next_link'] = 'Next Page<i class="fa fa-long-arrow-right"></i>';
        $config['next_tag_open'] = '<li>';
        $config['next_tag_close'] = '</li>';     
        $config["total_rows"] = $this->Product_model->record_count();            
        $config['per_page'] = $limit;
        $this->pagination->initialize($config);  
        $data['links'] = $this->pagination->create_links();
        $data['products'] = $this->Product_model->selectProducts($row,$limit);
        $this->load->view("allecadeaus", $data);
    }

Model:

function selectProducts($row,$limit)
        {   
            $query = $this->db->get('Your_table_name',$limit,$row);

            if ($query->num_rows() > 0){
              return $query->result_array();
            }
             else {
              return array();
            }

        }

function record_count(){        
        $this->db->from('Your_table_name');         
        $query = $this->db->get();
        $row = $query->num_rows();
        return $row;
    }

This will help you..thanks!
