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 "; //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： 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}> 更多关于zend相关内容感兴趣的读者可查看本站专题：《》、《》、《》、《》、《》、《》及《》 希望本文所述对大家基于Zend Framework框架的PHP程序设计有所帮助。 （编辑：安卓应用网） 【声明】本站内容均来自网络，其相关言论仅代表作者个人观点，不代表本站立场。若无意侵犯到您的权利，请及时与联系站长删除相关内容! |
