CodeIgniter 带有索引功能的分页

Question

我有一个产品列表，当我按下一个子类别时，它会加载该子类别中的所有产品并将索引用作：

http://localhost/ClickBasket/listproductscontroller/index?subcategory=4

因为它可以包含很多产品，所以我使用了 CI 的分页库。当我转到第二页或第三页时效果很好：

http://localhost/ClickBasket/listproductscontroller/index/1?subcategory=4
http://localhost/ClickBasket/listproductscontroller/index/2?subcategory=4

但是当我返回第一页时，它会丢失子类别的id：

http://localhost/ClickBasket/listproductscontroller/index

因此，在页面中找不到该子类别及其产品的数据。你如何解决这个问题？我还在学习 CodeIgniter 的分页库。

Answer 1

试试

我的代码：

//pagination
 $this->load->library('pagination');
 $config['base_url']   = site_url('/ClickBasket/listproductscontroller/index');
 $config['total_rows'] = $this->db->query('SELECT FOUND_ROWS() count;')->row()->count;
 $config['per_page']   = 9;
 #$config['uri_segment'] = 4;
 $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='disabled'><li class='active'><a href='#'>";
 $config['cur_tag_close']        = "<span class='sr-only'></span></a></li>";
 $config['next_tag_open']        = "<li>";
 $config['next_tagl_close']      = "</li>";
 $config['prev_tag_open']        = "<li>";
 $config['prev_tagl_close']      = "</li>";
 $config['first_tag_open']       = "<li>";
 $config['first_tagl_close']     = "</li>";
 $config['last_tag_open']        = "<li>";
 $config['page_query_string']    = true;
 $config['query_string_segment'] = 'page';
 $config['reuse_query_string']   = true;
 $config['use_page_numbers']     = true;
 $config['last_tagl_close']      = "</li>";
 $this->pagination->initialize($config);
