Zend Framework分页类用法详解，zendframework
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}>
