我們經(jīng)常在finder中使用”查看”列出改條數(shù)據(jù)的一些詳細(xì)信息，那么如果列出的信息太多導(dǎo)致一個頁面放不下了怎么辦呢？今天我就給大家講講如何在finder“查看”中進(jìn)行分頁。

首先，我們需要在lib/finder/xxx.php中添加構(gòu)建函數(shù)__construct()，進(jìn)行一些參數(shù)設(shè)定：

class notebook_finder_item{public function __construct($app){$this->app = $app;$this->render = app::get('notebook')->render();$this->controller = app::get('notebook')->controller('admin_notebook');$this->pagelimit=10;}

然后，在“查看”的方法中做以下修改：

function detail_email($id){if(!$id) return null;$render = app::get('notebook')->render();$nPage = $_GET['detail_email'] ? $_GET['detail_email'] : 1;$singlepage = $_GET['singlepage'] ? $_GET['singlepage']:false;$Oemail = kernel::single("notebook_mdl_item");$items = $Oemail->db->select('select item_email from sdb_notebook_item limit '.$this->pagelimit*($nPage-1).','.$this->pagelimit);$this->render->pagedata['item'] = $items;if($_GET['page']) unset($_GET['page']);$_GET['page'] = 'detail_email';$count =$Oemail->count();$render->pagedata['pager']=$a=$this->controller->pagination($nPage,$count,$_GET);return $this->render->fetch('admin/itememail.html');}

同時，我們要把detail_edit復(fù)制一份放到對應(yīng)的controller中，添加如下函數(shù)：

class notebook_ctl_admin_notebook extends desktop_controller{var $workground = 'notebook_ctl_admin_notebook';var $pagelimit = 10;public function __construct($app){parent::__construct($app);header("cache-control: no-store, no-cache, must-revalidate");}function detail_email($id=null){if(!$id) return null;$render = $this->app->render();$nPage = $_GET['detail_email'] ? $_GET['detail_email'] : 1;$Oemail = kernel::single("notebook_mdl_item");$items = $Oemail->db->select('select item_email from sdb_notebook_item limit '.$this->pagelimit*($nPage-1).','.$this->pagelimit);//print_r($nPage);die;$render->pagedata['item'] = $items;if($_GET['page']) unset($_GET['page']);$_GET['page'] = 'detail_email';$count =$Oemail->count();$render->pagedata['pager']=$this->pagination($nPage,$count,$_GET);return $render->fetch('admin/itememail.html');}public function pagination($current,$count,$get){ //本控制器公共分頁函數(shù)$app = app::get('notebook');$render = $app->render();$ui = new base_component_ui($this->app);$link = 'index.php?app=notebook&ctl=admin_notebook&act=ajax_html&id='.$get['id'].'&finder_act='.$get['page'].'&'.$get['page'].'=%d';//echo $link;$this->pagedata['pager'] = $ui->pager(array('current'=>$current,'total'=>ceil($count/$this->pagelimit),'link' =>$link,));return $this->pagedata['pager'];}public function ajax_html(){$finder_act = $_GET['finder_act'];//print_r($_GET['id']);die;$html = $this->$finder_act($_GET['id']);echo $html;}

最后一步，在html頁面中要顯示分頁信息的地方，加入變量<{$pager}>，就OK了！
