第一种：CListView分页 针对对象形式的数据分页
代码如下[Controller]
public function actionAjax() {
$criteria = new CDbCriteria();
//$criteria->order = "news_id DESC";
$criteria->condition = "user_id = 1";
$dataProvider = new CActiveDataProvider("News", array(
"pagination" => array(
"pageSize" => Yii::app()->params["pagesize"],
"pageVar" => Yii::app()->params["pagevar"],
),
"criteria" => $criteria,
));
$this->render("view", array(
"dataProvider" => $dataProvider,
));
}
[View]
widget("zii.widgets.CListView", array(
"dataProvider" => $dataProvider, //数据
"itemView" => "_view", //显示的模版
"id" => Yii::app()->controller->id,
"itemsTagName" => "ul",
"ajaxVar" => "", //默认为page或ajax 去掉后url更简洁
"htmlOptions" => array("class" => Yii::app()->controller->id),
"loadingCssClass" => "loading", //默认为list-view-loading
//"template" => "{summary}{sorter}{items}{pager}",//显示的顺序
//"ajaxUpdate" => false, //是否ajax分页 false或分页显示的容器id
//"beforeAjaxUpdate" => "before_ajax_update", //回调函数 在common.js里完成
//"afterAjaxUpdate" => "after_ajax_update",
"emptyText" => "
暂无数据！
", //无数据时显示内容
"pagerCssClass" => "pagination", //分页的class
"pager" => array(
"selectedPageCssClass" => "active", //当前页的class
"hiddenPageCssClass" => "disabled", //禁用页的class
"header" => "", //分页前显示的内容
"maxButtonCount" => 10, //显示分页数量
"htmlOptions" => array("class" => ""),
"firstPageLabel" => "首页",
"nextPageLabel" => "下一页",
"prevPageLabel" => "上一页",
"lastPageLabel" => "末页",
),
));
?>
第2种：CLinkPager 针对数组形式的数据分页
[Controller]
public function actionIndex() {
$criteria = new CDbCriteria();
$criteria->order = "news_id DESC";
$criteria->condition = "user_id = 1";
$count = News::model()->count($criteria);
$pages = new CPagination($count);
$pages->pageSize = 10;
$pages->applyLimit($criteria);
$list = News::model()->findAll($criteria);
$this->render("index", array("list" => $list, "pages" => $pages));
}
[View]
news_title; ?>
news_intro; ?>
widget("CLinkPager", array(
"pages" => $pages,
"selectedPageCssClass" => "active", //当前页的class
"hiddenPageCssClass" => "disabled", //禁用页的class
"header" => "", //分页前显示的内容
"maxButtonCount" => 10, //显示分页数量
"htmlOptions" => array("class" => ""),
"firstPageLabel" => "首页",
"nextPageLabel" => "下一页",
"prevPageLabel" => "上一页",
"lastPageLabel" => "末页",
)
);
?>
三. DAO实现分页.
[Controller层]
public function actionReport()
{
$sql = "select remitdate, sum(rate) sumrate from td_delivery
group by remitdate
order by remitdate desc";
$criteria=new CDbCriteria();
$result = Yii::app()->db->createCommand($sql)->query();
$pages=new CPagination($result->rowCount);
$pages->pageSize=2;
$pages->applyLimit($criteria);
$result=Yii::app()->db->createCommand($sql." LIMIT :offset,:limit");
$result->bindValue(":offset", $pages->currentPage*$pages->pageSize);
$result->bindValue(":limit", $pages->pageSize);
$posts=$result->query();
$this->render("report",array(
"posts"=>$posts,
"pages"=>$pages,
));
}
[View层]
$row["sumrate"]));?>
" ?>
//分页widget代码:
$this->widget("CLinkPager",array("pages"=>$pages));
?>
优点: DAO效率高; 缺点: view层需要自己写一些样式,稍显麻烦一点
四. widget实现分页
代码如下[model层]
/**
* @var string attribute : 日运费 (统计用)
* 需要对新增加的字段做个声明
*/
public $dayrate;
/*
* 统计功能: 统计每日的运费
*/
public function statistics()
{
$criteria = new CDbCriteria;
$criteria->select = "remitdate, sum(rate) AS dayrate";
$criteria->group = "remitdate";
return new CActiveDataProvider(get_class($this), array(
"criteria"=>$criteria,
"sort"=>array(
// 表头设置点击排序的字段
"attributes"=>array(
"remitdate",
"dayrate"=>array(
"asc"=>"dayrate",
"desc"=>"dayrate DESC",
)
),
"defaultOrder"=>"remitdate desc",
),
));
}
[Controller层]
/**
* 运单统计功能:
* 按日期统计
*/
public function actionReport()
{
$model=new Delivery("statistics");
$model->unsetAttributes(); // clear any default values
$this->render("report",array(
"model"=>$model,
));
}
[View层]
widget("zii.widgets.grid.CGridView", array(
"id"=>"delivery-grid",
"dataProvider"=>$model->statistics(),
"filter"=>$model,
"columns"=>array(
"remitdate",
"dayrate",
array(
"class"=>"CButtonColumn",
),
),
)); ?>
优点: 可以使用自带的样式; 缺点: 效率略低.
五，Ajax分页
YII中ajax分页有多种实现方法，比较传统的就是在view中写JS来实现，大概的就是这样:
在view中js大概逻辑是这样
代码如下$("#listview .yiiPager a").live("click",function(){
$.ajax({
url:$(this).attr("href"),
success:function(html){
$("#listview").html(html);
}
});
return false;//阻止a标签
});
然后在controller中判断ajax请求，再使用renderPartial方法渲染局部List视图，然后局部视图会被view中的ajax
方法填充到局部刷新的div中。controller的大概逻辑是
代码如下if (Yii::app()->request->isAjaxRequest) {
$this->renderPartial("_comments",array(
"model" => $model,
"comments" => $comments,//在局部视图中foreach得到每条数据
"pages" => $pages,
));
Yii::app()->end();
｝
后来发现YII中的CListview更方便，封装了分页，foreach显示list，还支持数据排序。具体的可以在YII的API手册
中发掘。使用CListview是默认ajax分页的，使用方法如下：
代码如下controller中：
$criteria = new CDbCriteria();
$criteria->order = "`create_time` DESC";
$dataProvider = new CActiveDataProvider("Comments", array(
"pagination"=>array(
"pageSize"=>Yii::app()->params["commentsPerPage"],//设置分页条数以确定取出数据的条数
),
"criteria"=>$criteria,
));
$this->render("comments",array(
"model" => $model,
"dataProvider" => $dataProvider,
));
然后在view中：
代码如下widget("zii.widgets.CListView", array(
"dataProvider"=>$dataProvider,
"itemView"=>"_comments",
//"ajaxUpdate"=> false,//这样就不会AJAX翻页
"pager" => array(//pager 的配置信息。默认为array("class"=>"CLinkPager").也可以自己配置
"nextPageLabel" => "下一页 »",
"prevPageLabel" => "« 上一页"
),
//在这里还可以配置一些排序规则，具体可以查阅手册
)); ?>
这样就实现了Ajax分页，很方便。
