CodeIgniter的分頁與指數函數

Question

我有，當我按下一個子類，它加載其所有產品在類別，然後使用該索引作爲一個產品列表：

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

，因爲它可能含有很多產品，我使用CI的分頁庫。它工作得很好，當我去到第二或第三頁：

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

但是，當我返回到第一頁，它會失去子類的ID：

http://localhost/ClickBasket/listproductscontroller/index 

因此，的數據子頁面中的子類別及其產品無法找到。你如何解決這個問題？我仍然在學習CodeIgniter的分頁庫。

嘗試

我的代碼：

//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);
