下家公司用的框架是yii,这几天看了下相关教程,今儿把分页教程写下,最后把tp的分页也给整合进了yii,因为个人觉得yii分页没有tp用的顺手。
首页,在models目录里创建个Auth.php的模型文件,里面写入
class Auth extends CActiveRecord {
public static function model($className = __CLASS__) {
return parent::model($className);
}
public function tableName() {
return '{{auth}}';
}
}
class IndexController extends Controller {
public function actionList() {
$criteria = new CDbCriteria();
$criteria->order = 'a_id desc';
$count = Auth::model()->count($criteria);
$page = new CPagination($count);
$page->pageSize = 10;
$page->applyLimit($criteria);
$auth = Auth::model()->findAll($criteria);
$this->renderPartial('auth', array('page' => $page, 'list' => $auth));
}
public function actionList1() {
$p = isset($_GET['page']) ? $_GET['page'] : 0;
$criteria = new CDbCriteria();
$criteria->select = "a_id,a_nickname";
$criteria->condition='';
$criteria->limit = 10;
$criteria->offset = $p == 0 ? 0 : (($p-1)*10);
$criteria->order = 'a_id desc';
$auth = Auth::model()->findAll($criteria);
$count = Auth::model()->count($criteria);
$page = new CPagination($count);
$page->pageSize = 10;
$page->applyLimit($criteria);
$this->renderPartial('auth', array('page' => $page, 'list' => $auth));
}
}
其中actionList和actionList1是$criteria的两种写法
最后在views目录里添加index目录,并在index目录内添加auth.php文件,里面写入
widget('CLinkPager',array(
'firstPageLabel'=>'首页',
'lastPageLabel'=>'末页',
'prevPageLabel'=>'上一页',
'nextPageLabel'=>'下一页',
'pages'=>$page,
'maxButtonCount'=>13,
)
);
?>
首先,把tp的AjaxPage.class.php和Page.class.php移动到yii的项目目录下的 protected/components下面,并且把文件名称分布改为AjaxPage.php和Page.php,分别进入两个文件,把里面的C方法去掉,也就是这一句
$this->varPage = C('VAR_PAGE') ? C('VAR_PAGE') : 'p' ;
改为
$this->varPage = 'p' ;
// autoloading model and component classes
'import'=>array(
'application.models.*',
'application.components.*',
),
其次,在protected/config.php/目录里新建一个common.php文件,这个文件就放些项目的公共函数,熟悉tp的朋友应该知道tp也有公共函数文件,很好用,这里借鉴下,yii应该也有吧,目前还没发现。在该文件写入
// 根据页码获取列表
function getListByPage($model, $select = '*', $condition = '', $limit = 10, $order = '', $p = '', $ajax = 0) {
// 初始化参数
$_GET['p'] = isset($_GET['p']) ? intval($_GET['p']) : 1;
$limit = intval($limit) > 0 ? intval($limit) : 10;
if ($p) {
$_GET['p'] = intval($p) ? intval($p) : 1;
}
$criteria = new CDbCriteria();
$count = $model->count($criteria);
if ($ajax) {
$Page = new AjaxPage($count, $limit);
} else {
$Page = new Page($count, $limit);
}
$result['page'] = trim($Page->show());
$criteria->select = $select;
$criteria->condition = $condition;
$criteria->limit = $Page->listRows;
$criteria->offset = $Page->firstRow;
$criteria->order = $order;
$list = $model->findAll($criteria);
$result['list'] = $list;
return $result;
}
这个文件可就要引入了,不然加载不了,可以在项目的入口文件index.php里自行引入,代码如下
require_once(dirname($config) . '/common.php');
public function actionPage() {
$model = Auth::model();
$info = getListByPage($model);
$this->renderPartial('page', array('info' => $info));
}
同时利用findAll也可以实现分页的查询效果,代码如下
function getListByPage($model, $select = '*', $condition = '', $limit = 10, $order = '', $p = '', $ajax = 0) {
if (!$model) {
return array();;
}
// 初始化参数
$_GET['p'] = isset($_GET['p']) ? intval($_GET['p']) : 1;
$limit = intval($limit) > 0 ? intval($limit) : 10;
if ($p) {
$_GET['p'] = intval($p) ? intval($p) : 1;
}
$count = $model->count();
if ($ajax) {
$Page = new AjaxPage($count, $limit);
} else {
$Page = new Page($count, $limit);
}
$result['page'] = trim($Page->show());
$result['list'] = $model->findAll(array(
'select' => $select,
'condition' => $condition,
'order' => $order,
'limit' => $Page->listRows,
'offset' => $Page->firstRow,
));
return $result;
}
