Detailed explanation of the usage of Zend Framework paging class, zendframework

The examples in this article describe the usage of Zend Framework paging class. Share it with everyone for your reference, the details are as follows:

1. Pagination class Pagination.php, it is best to put this class in the Zend directory

class XY_Pagination
{
  private $_navigationItemCount = 10; //导航栏显示导航总页数
  private $_pageSize = null; //每页项目数
  private $_align = "right"; //导航栏显示位置
  private $_itemCount = null; //总项目数

  private $_currentPage = null; //当前页
  private $_front = null; //前端控制器
  private $_PageParaName = "page"; //页面参数名称
  private $_firstPageString = "|<<"; //导航栏中第一页显示的字符
  private $_nextPageString = ">>"; //导航栏中前一页显示的字符
  private $_previousPageString = "<<"; //导航栏中后一页显示的字符
  private $_lastPageString = ">>|"; //导航栏中最后一页显示的字符
  private $_splitString = " | ";

2. Call in indexController Function in indexController.php:

require_once 'Zend/Pagination.php';
$Users = new Users();
//$rows = $Users->getAdapter()->fetchOne("select count(*) from users where `role`!='admin'"); //recorde count
$rows = $Users->fetchAll("`role`!='admin'")->count(); //查询记录总数
$rowsPerPage = 5; //perPage recordes
$curPage = 1;
if($this->_request->getParam('page'))
{
    $curPage = $this->_request->getParam('page');
}
//search data and display
$this->view->users = $Users->fetchAll("`role`!='admin'",'id desc',$rowsPerPage,($curPage-1)*$rowsPerPage)->toArray();
$Pager = new XY_Pagination($rows,$rowsPerPage);
$this->view->pagebar = $Pager->getNavigation();

3. It is easier to call paging in the view.

pagebar?>

or in case of smarty template
