CodeIgniter 2.0.3 Начальная страница класса Pagination Class

Вот код для переопределения встроенного класса разбиения на страницы. Поместите его в приложение / библиотеки и просто сделайте все остальное, как обычно.

Я добавил комментарий к каждой строке, которую я редактировал из исходного класса.

ПРИМЕЧАНИЕ. В вашем примере кода вы ставите общие страницы в значение конфигурации total_rows. Обязательно укажите общее количество записей, а не общее количество страниц.

 <?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) $this->cur_page; } } else { if ($CI->uri->segment($this->uri_segment) != 0) { $this->cur_page = $CI->uri->segment($this->uri_segment); // Prep the current page - no funny business! $this->cur_page = (int) $this->cur_page; } } $this->num_links = (int)$this->num_links; if ($this->num_links < 1) { show_error('Your number of links must be a positive number.'); } if ( ! is_numeric($this->cur_page) || $this->cur_page < 1) // EDITED { $this->cur_page = 1; // EDITED } // Is the page number beyond the result range? // If so we show the last page if (($this->cur_page * $this->per_page) > $this->total_rows) // EDITED { $this->cur_page = ($num_pages - 1); // EDITED } $uri_page_number = $this->cur_page; //$this->cur_page = floor(($this->cur_page/$this->per_page) + 1); // EDITED // Calculate the start and end numbers.

Номер в URL-адресе не является номером страницы, это смещение записи.

Например, если вы установите 25 записей на страницу:

 $config['per_page'] = 25; 

URL-адрес страницы 1 будет следующим:

 localhost/language/something/ 

и стр. 2:

 localhost/language/something/25 

и стр. 3 …

 localhost/language/something/50
