CodeIgniter 2.0.3分頁類起始頁

Question

我正在嘗試使用codeigniter分頁類。

這裏是我的代碼

$this->load->library('pagination'); 

$config['base_url'] = base_url('language/'.$this->uri->segment(2)); 
$config['total_rows'] = $page_count; 
$config['per_page'] = 1; 
$config['num_links'] = '2'; 
$config['uri_segment'] = '2'; 

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

$data['pages'] = $this->pagination->create_links(); 

但隨後，在第一頁的URL會看起來像

localhost/language/something/ 

，而第二頁是

localhost/language/something/1 

這看起來有點奇怪，是否有可能在第一頁上的URL從1開始？

以下是覆蓋內置分頁類的代碼。將它放在應用程序/庫中，然後像正常一樣完成所有其他操作。

我已經爲原始類的每一行添加了一條評論。

注意：在示例代碼中，您將總頁數放在total_rows config值中。請務必記錄總記錄數，而不是總頁數。

<?php if (! defined('BASEPATH')) exit('No direct script access allowed'); 

class MY_Pagination extends CI_Pagination { 

    function create_links() 
    { 
    // If our item count or per-page total is zero there is no need to continue. 
    if ($this->total_rows == 0 OR $this->per_page == 0) 
    { 
     return ''; 
    } 

    // Calculate the total number of pages 
    $num_pages = ceil($this->total_rows/$this->per_page); 

    // Is there only one page? Hm... nothing more to do here then. 
    if ($num_pages == 1) 
    { 
     return ''; 
    } 

    // Determine the current page number. 
    $CI =& get_instance(); 

    if ($CI->config->item('enable_query_strings') === TRUE OR $this->page_query_string === TRUE) 
    { 
     if ($CI->input->get($this->query_string_segment) != 0) 
     { 
     $this->cur_page = $CI->input->get($this->query_string_segment); 

     // Prep the current page - no funny business! 
     $this->cur_page = (int) $this->cur_page;

URL中的數字不是頁碼，它是記錄偏移量。

例如，如果你把它設置爲25條記錄每頁：

$config['per_page'] = 25; 

第1頁的URL會是這樣：

localhost/language/something/ 

和第2頁會是這樣：

localhost/language/something/25 

和第3頁...

localhost/language/something/50
