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}>
