Zend Framework分页类用法详解_php实例

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}>
