Second, PHP paging class calling example:

1. Get the number of pages returned by the URL:

  2. $cur_page = 1;
  3. if (isset($_GET["pageNo"])) {
  4. $cur_page = $_GET["pageNo"];
  5. }
Copy code

2, Create pagination object:

  2. $nums: the total number of certain data
  3. $page_size: the number displayed on each page
  4. $cur_page: the current page number
  5. $request: other optional URL request parameters
  6. $pager = new Pager($nums, $page_size , $cur_page, $request);
Copy code

3, smarty assignment:

  2. $show = Get the data to be displayed
  3. $this->tpl->assign('numlink', $pager->nextPage()); // Get the paging list
  4. $this-> ;tpl->assign('data',$show);
Copy code
