Zend Framework分页类用法详解

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}>
