Explication détaillée des exemples de pagination utilisant CLinkPager dans Yii

Cet article explique principalement comment utiliser CLinkPager pour la pagination dans YII. Ici, nous utilisons la forme des objets pour définir la pagination :

Personnalisez d'abord LinkPager dans les composants et héritez du code spécifique de CLinkPager

Comme suit :

<?php

 */

 /**

 return $buttons;
 }
  
 protected function createTotalButton($label,$class,$hidden,$selected)
 {
 if($hidden || $selected)
  $class.=&#39; &#39;.($hidden ? self::CSS_HIDDEN_PAGE : self::CSS_SELECTED_PAGE);
 return &#39;<li class="&#39;.$class.&#39;">&#39;.CHtml::label($label,false).&#39;</li>&#39;;
 }
  
 /**

Opération dans le contrôleur :

//分页操作
$criteria=new CDbCriteria;
$criteria->order='id DESC';
$criteria->select=array('id','uid','username','title','thumb','url','clicks','time','dateline','countfavorite','quality');
$criteria->condition=$sql;
$total = Video::model()->count($criteria);
 
$pages = new CPagination($total); 
$pages->pageSize=self::PAGE_SIZE;
$pages->applyLimit($criteria);
   
$list = Video::model()->findAll($criteria);
 
$title = CommonClass::model()->find(array(
 'select'=>array('cname'),
 'condition'=>'id = '.$id,
)); 
 
$this->render('application.views.video.list',array(
 'array'=>$array,
 'arr'=>$arr,
 'result'=>$result,
 'list'=>$list,
 'pages'=>$pages,
 'title'=>$title,
));

Référencé dans vues/video/list.php :

<?php
 $this->widget(&#39;LinkPager&#39;, array(&#39;pages&#39; => $pages,));
 ?>
