Ci-dessous, j'ai résumé quelques méthodes de pagination Yii et des exemples de codes couramment utilisés dans Yii. Voici la pagination ordinaire et la pagination ajax. J'espère que cet article sera utile à tout le monde.
Le premier type : pagination CListView Pour la pagination des données sous forme d'objet
Contrôleur :
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, )); }
Vue :
<?php $this->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' => ' <DIV class="alert alert-waning"> 暂无数据! </DIV> ', //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', ), )); ?>
Le deuxième type : CLinkPager Pour les données de pagination sous forme de tableau
Contrôleur :
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' => $pages)); }
Vue :
<UL> <?php foreach ($list as $item): ?> <LI> <DIV class=page-header> <?php echo $item--->news_title; ?> </DIV> <DIV class=content> <?php echo $item--->news_intro; ?> </DIV> </LI> <?php endforeach; ?> </UL> <DIV class=pagination> <?php $this--->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', ) ); ?> </DIV>
Le troisième type : DAO implémente la pagination.
Contrôleur Couche :
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'=>$pages, )); }
Couche de vue :
<?php foreach($posts as $row):?> <?php echo CHtml::link($row["remitdate"],array('delivery/view','remitdate'=>$row["sumrate"]));?> <?php echo $row["sumrate"]."<br />" ?> <?php endforeach;?> <?php //分页widget代码: $this->widget('CLinkPager',array('pages'=>$pages)); ?>
Avantages : DAO est très efficace Inconvénients : La couche de vue doit écrire elle-même certains styles, ce qui est un peu gênant <🎜 ; >
Chapitre quatre types : le widget implémente la pagination Couche de modèle :/** * @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', ), )); }
/** * 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, )); }
<?php $this->widget('zii.widgets.grid.CGridView', array( 'id'=>'delivery-grid', 'dataProvider'=>$model->statistics(), 'filter'=>$model, 'columns'=>array( 'remitdate', 'dayrate', array( 'class'=>'CButtonColumn', ), ), )); ?>
La logique approximative de js dans la vue est la suivante
$('#listview .yiiPager a').live('click',function(){ $.ajax({ url:$(this).attr('href'), success:function(html){ $('#listview').html(html); } }); return false;//阻止a标签 });
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(); }
$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, ));
<?php $this->widget('zii.widgets.CListView', array( 'dataProvider'=>$dataProvider, 'itemView'=>'_comments', //'ajaxUpdate'=> false,//这样就不会AJAX翻页 'pager' => array(//pager 的配置信息。默认为<CODE>array('class'=>'CLinkPager')</CODE>.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 )); ?>
