本文实例讲述了Zend Framework分页类用法。分享给大家供大家参考，具体如下：

1、分页类Pagination.php，最好是把这个类放在Zend目录下

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 $_pageCount = null; //总页数
 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 $_splitString = " | ";
 //页数字间的间隔符 /
 public function __construct($itemCount, $pageSize)
 {
 if(!is_numeric($itemCount) || (!is_numeric($pageSize)))
 throw new Exception("Pagination Error:not Number");
 $this->_itemCount = $itemCount;
 $this->_pageSize = $pageSize;
 $this->_front = Zend_Controller_Front::getInstance();
 $this->_pageCount = ceil($itemCount/$pageSize); //总页数
 $page = $this->_front->getRequest()->getParam($this->_PageParaName);
 if(empty($page) || (!is_numeric($page))) //为空或不是数字，设置当前页为1
 {
 $this->_currentPage = 1;
 }
 else
 {
 if($page < 1)
 $page = 1;
 if($page > $this->_pageCount)
 $page = $this->_pageCount;
 $this->_currentPage = $page;
 }
 }
 /**
 * 返回当前页
 * @param int 当前页
 */
 public function getCurrentPage()
 {
 return $this->_currentPage;
 }
 /**
 * 返回导航栏目
 * @return string 导航html class="PageNavigation"
 */
 public function getNavigation()
 {
 $navigation = '';
 $pageCote = ceil($this->_currentPage / ($this->_navigationItemCount - 1)) - 1; //当前页处于第几栏分页
 $pageCoteCount = ceil($this->_pageCount / ($this->_navigationItemCount - 1)); //总分页栏
 $pageStart = $pageCote * ($this->_navigationItemCount -1) + 1; //分页栏中起始页
 $pageEnd = $pageStart + $this->_navigationItemCount - 1; //分页栏中终止页
 if($this->_pageCount < $pageEnd)
 {
 $pageEnd = $this->_pageCount;
 }
 $navigation .= "总共：{$this->_itemCount}条　{$this->_pageCount}页\n";
 if($pageCote > 0) //首页导航
 {
 $navigation .= '$this->_firstPageString ";
 }
 if($this->_currentPage != 1) //上一页导航
 {
 $navigation .= '$this->_previousPageString ";
 }
 while ($pageStart <= $pageEnd) //构造数字导航区
 {
 if($pageStart == $this->_currentPage)
 {
 $navigation .= "$pageStart".$this->_splitString;
 }
 else
 {
 $navigation .= '$pageStart".$this->_splitString;
 }
 $pageStart++;
 }
 if($this->_currentPage != $this->_pageCount) //下一页导航
 {
 $navigation .= ' $this->_nextPageString ";
 }
 if($pageCote < $pageCoteCount-1) //未页导航
 {
 $navigation .= '$this->_lastPageString ";
 }
 //添加直接导航框
 //$navigation .= '';
 //2008年8月27号补充输入非正确页码后出现的错误——begin
 $navigation .= ' ';
 //2008年8月27号补充输入非正确页码后出现的错误——end
 $navigation .= " ";
 return $navigation;
 }
 /**
 * 取得导航栏显示导航总页数
 *
 * @return int 导航栏显示导航总页数
 */
 public function getNavigationItemCount()
 {
 return $this->_navigationItemCount;
 }
 /**
 * 设置导航栏显示导航总页数
 *
 * @param int $navigationCount:导航栏显示导航总页数
 */
 public function setNavigationItemCoun($navigationCount)
 {
 if(is_numeric($navigationCount))
 {
 $this->_navigationItemCount = $navigationCount;
 }
 }
 /**
 * 设置首页显示字符
 * @param string $firstPageString 首页显示字符
 */
 public function setFirstPageString($firstPageString)
 {
 $this->_firstPageString = $firstPageString;
 }
 /**
 * 设置上一页导航显示字符
 * @param string $previousPageString:上一页显示字符
 */
 public function setPreviousPageString($previousPageString)
 {
 $this->_previousPageString = $previousPageString;
 }
 /**
 * 设置下一页导航显示字符
 * @param string $nextPageString:下一页显示字符
 */
 public function setNextPageString($nextPageString)
 {
 $this->_nextPageString = $nextPageString;
 }
 /**
 * 设置未页导航显示字符
 * @param string $nextPageString:未页显示字符
 */
 public function setLastPageString($lastPageString)
 {
 $this->_lastPageString = $lastPageString;
 }
 /**
 * 设置导航字符显示位置
 * @param string $align:导航位置
 */
 public function setAlign($align)
 {
 $align = strtolower($align);
 if($align == "center")
 {
 $this->_align = "center";
 }elseif($align == "right")
 {
 $this->_align = "right";
 }else
 {
 $this->_align = "left";
 }
 }
 /**
 * 设置页面参数名称
 * @param string $pageParamName:页面参数名称
 */
 public function setPageParamName($pageParamName)
 {
 $this->_PageParaName = $pageParamName;
 }
 /**
 * 获取页面参数名称
 * @return string 页面参数名称
 */
 public function getPageParamName()
 {
 return $this->_PageParaName;
 }
 /**
 * 生成导航链接地址
 * @param int $targetPage:导航页
 * @return string 链接目标地址
 */
 private function createHref($targetPage = null)
 {
 $params = $this->_front->getRequest()->getParams();
 $module = $params["module"];
 $controller = $params["controller"];
 $action = $params["action"];
 $targetUrl = $this->_front->getBaseUrl()."/$module/$controller/$action";
 foreach ($params as $key => $value)
 {
 if($key != "controller" && $key != "module" && $key != "action" && $key != $this->_PageParaName)
 {
 $targetUrl .= "/$key/$value";
 }
 }
 if(isset($targetPage)) //指定目标页
 $targetUrl .= "/$this->_PageParaName/$targetPage";
 else
 $targetUrl .= "/$this->_PageParaName/";
 return $targetUrl;
 }
}
?>

2、在indexController.php中的indexController Function里面调用：

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、在view中调用分页更简单了。

pagebar?>

或者在smarty模板情况下

<{$pagebar}>
